[00:16] <davidmitchell> If I'd like to submit a patch to ffmpeg, is it acceptable to submit a pull request to the GitHub mirror, or do I really need to subscribe to the mailing list and email it? [00:20] <kierank> mailing list is better [00:20] <durandal_1707> davidmitchell: http://ffmpeg.org/contact.html [00:22] <davidmitchell> Thanks, durandal_1707, I read that and only found the link to the MPlayer patch guidelines, which are still geared towards svn [00:22] <davidmitchell> did I miss a link? [00:25] <durandal_1707> davidmitchell: http://libav.org/developer.html#Submitting-patches (our fork) [00:26] <durandal_1707> replace every occurence of libav with ffmpeg [00:34] <kierank> davidmitchell: http://ffmpeg.org/developer.html#Submitting-patches-1 [00:38] <davidmitchell> wow, that's buried pretty deeply [00:42] <michaelni> suggestions, patches and pull requests to improve the docs are welcome! [00:44] <michaelni> also you dont strictly have to subscribe but if you dont it may take a day or 2 until the mail shows up [00:44] <michaelni> depends on how busy the ML people are [00:57] <CIA-31> ffmpeg: 03Michael Niedermayer 07master * r1843e6c8aa 10ffmpeg/libavcodec/mjpegdec.c: [00:57] <CIA-31> ffmpeg: thp: Fix handling of restart interval [00:57] <CIA-31> ffmpeg: Fixes Ticket903 [00:57] <CIA-31> ffmpeg: Signed-off-by: Michael Niedermayer <michaelni(a)gmx.at> [00:57] <CIA-31> ffmpeg: 03Michael Niedermayer 07master * ra91f206665 10ffmpeg/libavcodec/mjpegdec.c: [00:57] <CIA-31> ffmpeg: ljpegdec: reset restart interval for each plane of a non interleaved file.

However, a git pull doesn't show this happening. What is the status for it in ffmpeg? [03:19] <Compn> michaelni will know :) [03:19] <Compn> whats libpostproc do again ? hasnt it been on depreciated list for years ? [03:21] <Compn> of course sometimes michaelni merges things from libav that he shouldnt.. it happens when merging 1000s of commits [03:23] <Snaggle> I'm just curious as to the discrepancy between gitweb and a git pull. I don't have a preference as to which way to actually go [03:23] <Compn> ah, sometimes merges show up in the commit but arent actually merged to git [03:24] <Compn> it will list everything as merged, even things that are marked as not-to-be-merged [03:24] <Compn> at least it did in the past on the list [03:25] <Snaggle> ahh [03:26] Action: Snaggle pokes gitweb for not being clear [03:27] <michaelni> we wont deprecate libpostproc [03:27] <michaelni> the commit was not merged but showed up, like compn said ... [03:27] <ohsix> git log, there was some messages about it [03:28] <ohsix> oicnm [03:28] <michaelni> i guess i should have replied on the ML or added a note to the merge commit to clarify [03:29] <Snaggle> michaelni: no biggie. I was just curious [03:29] <Compn> i find it wrong that libav removed sonic riff tags [03:29] <Compn> i guess they dont care about decoding currently existing samples [03:30] <Compn> wonder if anyone used it as a codec ever :) [03:42] <Compn> michaelni : it might make sense to start a kind of running ffmpeg-libav changelog [03:42] <Compn> well, thats probably a lot of work [03:43] <Compn> and maybe no one even cares about the differences [07:42] <CIA-31> ffmpeg: 03Michael Niedermayer 07master * r668a74e808 10ffmpeg/tests/Makefile: [07:42] <CIA-31> ffmpeg: buildsystem: add $EXESUF to the used tool for fate [07:42] <CIA-31> ffmpeg: Signed-off-by: Michael Niedermayer <michaelni(a)gmx.at> [07:42] <CIA-31> ffmpeg: 03Michael Niedermayer 07master * rd9816cd5df 10ffmpeg/libavcodec/imgconvert.c: [07:42] <CIA-31> ffmpeg: imgconvert: add PIX_FMT_GRAY8A to pix_fmt_info [07:42] <CIA-31> ffmpeg: Fixes selecting gray8a for PAM [07:42] <CIA-31> ffmpeg: Signed-off-by: Michael Niedermayer <michaelni(a)gmx.at> [10:23] <CIA-31> ffmpeg: 03Nicolas George 07master * rbbf372e145 10ffmpeg/libavfilter/vf_overlay.c: overlay: do not leak x/y expressions.

[00:30] <toolfan> I'm trying to use FFmpeg in my app for encoding, and I suspect that I may be using the wrong pixel format. I've looked through the docs, but I can't seem to find a list of which formats each encoder supports. Is there such a list, or will I have to look through the source for this info? [01:06] <lahwran> how would I convert from animated gif using ffmpeg? it seems to be only reading the first frame :/ [01:16] <falip> toolfan: not sure if this will help you but ffmpeg -formats and ffmpeg -codecs [01:18] <falip> toolfan: as to which which encoders each format supports, I don't know, i've asked similar questions, usually people just seem to know for containers and codecs they use frequently. [01:18] <lahwran> oh hm [01:19] <lahwran> seems that it has multiple frames but far too high framerate [01:36] <toolfan> falip: ok, thanks. I guess I'll have to dive into the source to get a definitive answer. [02:13] <Arthur_D> hi, how do I output ffprobe to a file? Tried ffprobe file.avi > output.txt but it doesn't work [02:16] <grepper> ffprobe file.avi > output.txt 2>&1 [02:18] <Arthur_D> thank you very much :) [05:57] <llrcombs> is there a way to give ffplay a playlist of files and have it play them one by one? (possibly displaying a default image or looping a default video if it runs out of files to play) [06:00] <llrcombs> if not, I suppose I can use VLC [06:03] <lahwran> will it not take it if you just give it more than one? [06:03] <lahwran> perhaps multiple -i [06:04] <llrcombs> lahwran: I want to be able to add items to the playlist as it goes [06:04] <llrcombs> so it looks like VLC is where I should be [06:04] <lahwran> ffplay is rather minimal [06:04] <llrcombs> ffplay's probably not the best choice for anything that complex [06:04] <lahwran> so yes [06:05] <llrcombs> only thing I can't find in VLC is making it loop a default file if it runs out of playlist items [06:05] <lahwran> I'm trying to convert from gif to avi - I'm using a three step process where I detect the gif's frame "rate", use imagemagick "convert" to convert to png, and then convert to avi with ffmpeg -r <detected framerate> -i <gif file> <avi file> [06:06] <lahwran> https://gist.github.com/38590783d681126c6ae4 < this is my code - gif2avi.py [06:06] <llrcombs> anything going wrong? [06:06] <lahwran> however, it's resulting in a damaged avi file [06:06] <lahwran> and I don't understand why [06:06] <llrcombs> did you specify a video codec? [06:06] <lahwran> no [06:06] <llrcombs> try that [06:07] <lahwran> what's a good one for very small files? [06:07] <llrcombs> I usually reccomend x264 for nearly anything, as it's pretty versatile [06:07] <lahwran> I have plenty of space and encoding speed is a priority, that still your recommendation? [06:07] <llrcombs> x264 can be very fast [06:08] <llrcombs> there's actually a "veryfast" setting [06:08] <lahwran> -vcodec x264, yes? [06:08] <llrcombs> I think it's libx264, actually [06:08] <llrcombs> are these gifs animations? [06:08] <lahwran> yes [06:08] <llrcombs> -preset veryfast -tune animation [06:09] <lahwran> erm [06:09] <lahwran> wait, what do you mean by "animation? [06:09] <lahwran> " [06:09] <lahwran> they're various content, some of them converted video [06:09] <llrcombs> then take out the -tune animation part [06:10] <llrcombs> if it needs to be faster, set it to superfast. If you can bear slower, set it to faster [06:10] <llrcombs> do the output files need to decode fast? [06:11] <lahwran> Unrecognized option 'preset' [06:11] <lahwran> fast enough to play is all [06:11] <llrcombs> that's strange [06:11] <llrcombs> what's the exact command, and what version are you on? [06:11] <llrcombs> ffmpeg -version [06:12] <lahwran> FFmpeg 0.6-4:0.6-2ubuntu6 [06:12] <llrcombs> ahh, that's old [06:12] <llrcombs> go grab 0.9.1 [06:12] <llrcombs> or latest git [06:12] <lahwran> I'd prefer not to compile it if I don't have to [06:12] <lahwran> compiling takes ages on this cpu [06:12] <llrcombs> 0.6 is not actively maintained [06:13] <llrcombs> you need to move to a newer version [06:13] <llrcombs> you might be able to find a precompiled one [06:14] <llrcombs> if you can't find one, I might be able to cross-compile it for you [06:15] <lahwran> I'll grab it from https://launchpad.net/~jon-severinsson/+archive/ffmpeg [06:16] <llrcombs> ahh, good [06:16] <llrcombs> grab that, then try it [06:18] <lahwran> suddenly: everything breaks [06:18] <lahwran> (it's still installing) [06:18] <lahwran> nope, same result [06:19] <lahwran> Unrecognized option 'preset'\nFailed to set value 'veryfast' for option 'preset' [06:19] <llrcombs> what's ffmpeg -version say? [06:19] <lahwran> ffmpeg 0.9.1-4:0.9.1-0ubuntu1~jon1~maverick1 [06:20] <llrcombs> hmm [06:20] <llrcombs> try with -vpre instead of -preset [06:20] <llrcombs> what's the build date? [06:20] <lahwran> I dunno [06:21] <lahwran> how do I find out? :P [06:21] <llrcombs> it's in -version [06:21] <lahwran> https://gist.github.com/769199a7a63f3fdf339e [06:21] <lahwran> 2012-01-07 on the ubuntu ppa page [06:22] <lahwran> -vpre works somewhat better; recognizes the option, but not the preset "veryfast" [06:22] <lahwran> "File for preset 'veryfast' not found" [06:22] <llrcombs> hmm, -preset was added on 2011-5-3, so it should be fine... [06:23] <llrcombs> list the files in /usr/local/share/ffmpeg [06:23] <lahwran> no such file or directory [06:23] <lahwran> https://gist.github.com/a0bb05df4b6317454ea8 [06:28] <lahwran> when I remove the vpre option, it says Unknown encoder 'libx264' [06:28] <llrcombs> ahh, there's our problem [06:28] <llrcombs> your build is compiled without libx264 [06:28] <lahwran> heavenly. [06:28] <llrcombs> you could try another codec [06:28] <llrcombs> or another build [06:28] <llrcombs> maybe it has libvpx? [06:28] <lahwran> sounds like I'll have to build it myself after all [06:28] <llrcombs> or theora [06:28] <llrcombs> or mpeg4 [06:29] <lahwran> hm [06:29] Action: lahwran tries mpeg4 [06:30] <lahwran> that worked. [06:30] <lahwran> thanks! [06:31] <llrcombs> if you need encoding to be even faster, I reccomend building your own ffmpeg with libx264 and setting it to veryfast. Otherwise, stick with your current settings, maybe mess with the arguments a bit [07:06] <lahwran> llrcombs: hm, half an hour of encoding [07:06] <lahwran> and then I try to play a file and vlc crashes and ffplay spews crap [07:08] <lahwran> ffplay does play it sort of though, however completely different problem seems to be occurring (in addition to the damaged file, which I'm still confused about) - the delta frames are shown as mostly-black images, probably due to the imagemagick convert command not interpolating the frames [10:44] <lahwran> hm, configure doesn't seem to be finding my lame installation [10:44] <lahwran> https://gist.github.com/cba048dea6db7fe17579 [10:44] <lahwran> pretty sure I built it myself ages ago [14:49] <ackbahr> Hi! What should I do about this message (and an output file that contains only audio)? [14:50] <sacarasc> About what message? [14:50] <ackbahr> sacarasc: Hey, you'r here as well? Good question.... This one : [mpeg @ 0x17c2e20] VBV buffer size not set, muxing may fail [14:51] <Mavrik> paste whole command line and output to a pastebin [14:51] <Mavrik> that message isn't helpful [14:52] <ackbahr> Mavrik: ok! [14:53] <KuroiTsuki> hi. umm, someone of mplayer/mencoder team told me that someone from ffmpeg team don't want to fix issue when embedded subs of mkv stay longer than they are supposed to in result video. why is that ffmpeg team don't want to fix issue? [14:54] <ackbahr> Mavrik: http://pastebin.com/FCaDeaTd [14:54] <Mavrik> KuroiTsuki, we're mostly not developers here [14:54] <Mavrik> mailing lists are the right way to communicate with the devs [14:56] <Mavrik> ackbahr, what are you trying to achieve with the command line? re-encode a 3gp to a mpeg2 file? [14:56] <KuroiTsuki> ffmpeg-user or ffmpeg-devel? [14:56] <ackbahr> Yes; in fact it's a script for all my cameras/phones/etc. [14:56] <Mavrik> KuroiTsuki, devel [14:56] <Mavrik> (probably) [14:57] <KuroiTsuki> lol [14:57] <KuroiTsuki> i see, thank you :) [14:57] <ackbahr> It makes smaller versions of all videos that can be e-mailed as is (are?). [14:57] <Mavrik> ackbahr, ffmpeg is sensitive to order of command line parameters [14:57] <Mavrik> now you're forcing ffmpeg to interpret your input as mpeg-2 video and encode with a default codec (mpeg-1 it seems) [14:58] <Mavrik> you need to move the -vcodec parameter after the "-i" input file parameter [14:58] <ackbahr> Mavrik: seems I recall that from the beginning of the man page, but didn't think about it here... Great! [14:58] <Mavrik> ackbahr, you'll also have to move other parameters [14:59] <Mavrik> do something like [14:59] <Mavrik> ffmpeg -y -i <file> -vcodec -deinterlace -threads 4 [14:59] <Mavrik> because right now -deinterlace (might) not work and "-threads 4" sets decoding threads not encoding threads [15:00] <Mavrik> you're not getting any video because your input is probably H.264 and you're forcing a MPEG-2 decoder to decode it :) [15:01] <ackbahr> Mavrik: Just moving the -vcodec seemed to work, but I might get quicker results with -thread in the right place.... Or in both? [15:02] <Mavrik> just move it after -i... you won't get any significant speedups if you set them for decoding [15:03] <ackbahr> Ok. What about deinterlace? [15:03] <ackbahr> Mavrik: Only an encoding feature? [15:04] <Mavrik> yeah [15:04] <Mavrik> but I'm not sure about that one, it was replaced by -vf yadif (video filter) in new versions [15:04] <ackbahr> Mavrik: Do you think I should use this one? [15:05] <Mavrik> yadif is a better filter, I'm just not sure if it works with your ffmpeg [15:05] <Mavrik> anyway, gotta go, :) [15:05] <ackbahr> Mavrik: Thanks a lot, you made my day! [16:16] <CrazyThinker> What is the best way to convert a mkv(h264) video to mp4(mpeg-4)? [16:17] <CrazyThinker> losslessly [16:17] <CrazyThinker> I tried doing just ffmpeg -i file.mkv file.mp4 -s hd1080 [16:17] <CrazyThinker> but it destroyed the quality of the video [16:25] <JEEB> do you want to change the video codec or do you just want to remux [16:25] <JEEB> if you just want to remux it'll be lossless [16:26] <JEEB> mpeg4 codec (mpeg-4 part 2 has no lossless mode) [16:26] <JEEB> so switching video codecs would be lethal [16:26] <JEEB> ffmpeg -i input.mkv -acodec copy -vcodec copy out.mp4 [16:26] <JEEB> ^ this would copy audio and video streams from the input and would mux them into mp4 [16:30] <CrazyThinker> JEEB, my TV has a problem with h264 encoding [16:30] <CrazyThinker> so I want to preserve the quality and convert it to avi or mpg [16:30] <CrazyThinker> is that possible? [16:31] <JEEB> you can use a lot of bitrate and make it look similar'ish [16:31] <JEEB> but it isn't lossless :P [16:31] <JEEB> anyways, I have no idea about the settings you have to give the mpeg4 encoder so don't ask me [16:32] <JEEB> I don't encode for crappy plastic toys in anything else but H.264, thankfully [16:33] <CrazyThinker> Thanks anyway [18:37] <stonie> hi.. i want to create a video from single images.. trying with "ffmpeg -f image2 -i DSC_%04d.JPG foo.avi" always gives me "DSC_%04d.JPG: No such file or directory" .. files are all caled DSC_1159.JPG... DSC_1270.JPG [18:39] <relaxed> the number sequence must start at (or near) zero [18:40] <relaxed> you can cat jpgs though, cat *.JPG | ffmpeg -f image2pipe -vcodec mjpeg -i - [19:42] <stonie> ok thanks trying that [20:05] <BLZbubba> hello there, does anyone have a good command line for making high quality ipod touch 4g mp4 files? [20:13] <Mavrik> can you tell the H.264 profile and level it supports? [21:22] <cbreak> BLZbubba: H.264 video up to 720p, 30 frames per second, Main Profile level 3.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats [21:22] <cbreak> from apple's page [21:22] <cbreak> h.264 is the highest quality codec those things support [21:23] <cbreak> And iPhones: H.264 video up to 1080p, 30 frames per second, High Profile level 4.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats [21:23] <cbreak> (the 4S variant) [21:24] <cbreak> no idea how ffmpeg exposes those, but x264 has a --level switch [21:26] <JEEB> -level -profile:v [21:26] <JEEB> -profile:v main [21:26] <JEEB> -level 3.1 [21:26] <JEEB> should work [21:27] <relaxed> if that fails, -level 31 [23:41] <JodaZ> wait, so what color space is video normally encoded in ? [23:41] <JodaZ> like h264 on your standard blueray [23:45] <Mavrik> yuv420 probably [23:45] <Mavrik> it's the only really widely supported pixel format with acceleration everywhere [23:53] <JodaZ> Mavrik, what does that mean ? y is 4 bit and u is 2 ? [23:53] <JodaZ> i don't get the fancy box graphics on wiki [23:55] <Mavrik> JodaZ, it means that every 8 pixels (two rows of 4) of black and white information get two 2x2 blocks of color information [23:56] <Mavrik> JodaZ, http://en.wikipedia.org/wiki/Chroma_subsampling#Sampling_systems_and_ratios [00:00] --- Mon Jan 16 2012

[00:37] <funman> ok finally got it [00:37] <funman> http://pastie.org/3181237 [00:37] <funman> the .exe and dlls all have debug symbols [00:38] <funman> i can insert breakpoints and have complete backtraces when they happen [00:38] <Compn> lol [00:38] <Compn> ok that is a useless backtrace [00:38] <funman> indeed but the other binary i have (without symbols) actually show function name in the bt [00:38] <Compn> no function names [00:40] <uau> funman: do you have function names when you set a breakpoint elsewhere? [00:40] <funman> it just says it's in DXVA2CreateVideoService() from Windows' dxva2.dll [00:40] <uau> could be that the issue is that the stack is corrupted [00:40] <funman> uau: yeah, just checked with WinMain [00:40] <funman> likely [00:40] <uau> so it would not be an issue looking up the names, but the addresses might not correspond to functions [00:42] <funman> even the last one? [00:42] <funman> shouldn't it be resolved from IP/PC ? [00:43] <uau> well maybe it crashed after jumping to a return address read from corrupted stack [00:43] <funman> true [00:43] <funman> it's Windows code so we dont know [00:43] <uau> you could check whether the asm makes any sense [00:45] <funman> the address doesn't make sense at all [00:45] <funman> "No function contains program counter for selected frame." [00:46] <funman> VLC looks if that function exist but doesn't call it [00:46] <uau> i think that message you quoted only means there's no debug info [00:46] <uau> so it can't automatically show asm for exactly the whole function [00:46] <funman> ah but it comes from 'disassemble' [00:46] <uau> you need to give it more arguments probablly [00:47] <funman> ooh ok [00:47] <funman> well it makes sense [00:47] <funman> it is NULL dereference [00:47] <uau> what is? [00:48] <funman> http://pastie.org/3181294 [00:48] <funman> rdx = 0 [00:49] <uau> that looks like meaningful code though [00:49] <funman> ffmpeg has no reference to DXVA2CreateVideoService [00:49] <uau> so lack of debug info rather than a random address [00:49] <funman> uau: yeah, the first line is *(rdx) = rax; iiuc (translated to C) [00:50] <uau> well that alone could happen to occur in random memory [00:50] <funman> yeah [00:50] <uau> i mean that overall the asm looks like a meaningful function [00:51] <funman> the second function in the backtrace doesnt point to valid memory though [00:52] <funman> in any case it's annoying to debug [00:55] <funman> ah and i dont see symbols defined in vlc .dll s [00:56] <funman> http://pastie.org/3181327 [00:57] <funman> enough for today :) [00:57] <uau> funman: was that after starting the process? [00:58] <funman> yes [00:59] <funman> same thing if i don't run the process [00:59] <funman> i'll ask help on #mingw-w64 they are helpful - just need some timezone concordance [01:00] <uau> so the libraries should already have been loaded? [01:00] <funman> yeah [01:00] <funman> well maybe [01:00] <funman> DLLs are special [01:03] <funman> ramiro left a long time ago? last time i saw him was 1 year ago or something [01:04] <michaelni> last post from ramiro on ffmpeg-dev was 5 Nov 2011, thats not so long ago [01:13] <Compn> ramiro left irc and stopped his autobuilds site after the fork [01:13] <Compn> but i saw him once or twice on the list [01:13] <Compn> or something [01:17] <CIA-31> ffmpeg: 03Carl Eugen Hoyos 07master * r7c10d3ca2e 10ffmpeg/libavcodec/ (pamenc.c version.h): [01:17] <CIA-31> ffmpeg: Simplify 32bit RGB pam encoding.

[00:00] <llrcombs> but not on x264, yeah? [00:00] <JEEB> with everything [00:00] <JEEB> it's something you only use when you're developing something that needs the same qp values [00:00] <llrcombs> heh, someone told me it didn't work with x264 [00:00] <JEEB> because qp is not something you use for normal encodes .-. [00:00] <JEEB> well, in any case it's not something to use [00:00] <llrcombs> how do you force it to be the same actual _quality_? [00:01] <JEEB> you'll have to buy a few thousand chinese child laborers for that [00:01] <llrcombs> or do you just have to mess around until you find a good compromise between size and quality? [00:01] <JEEB> because there is no automated way to find the same quality for your eyes [00:01] <JEEB> the closest alternative is to use -crf [00:01] <JEEB> and find the highest crf value that still looks good for you [00:01] <JEEB> start at around 24 [00:01] <JEEB> and if it looks bad, lower it [00:02] <JEEB> values lower than 18 aren't usually needed, so don't lower it too much from 24 before trying stuff in the middle [00:02] <llrcombs> 0 is lossless, right? [00:02] <JEEB> 0 is lossless mode with 8bit libx264 [00:02] <JEEB> with >8bit libx264 the crf values start to go negative as well [00:03] <JEEB> thus it's better off to use -qp 0 for lossless if you think you ever will use >8bit libx264 [00:03] <JEEB> if you use only 8bit libx264 you can use crf zero just fine [00:03] <llrcombs> what would you reccomend for MJPEGs? [00:04] <llrcombs> if I want the highest quality possible and the original file is MJPEG [00:04] <JEEB> no idea, I only use ffvhuff and libx264 [00:04] <llrcombs> I used -sameq at first to go to libx264, since I didn't really understand what it did [00:04] <JEEB> well, if you want to have a lossless copy of the file in H.264 then you can use -crf 0 [00:04] <JEEB> and have a lossless copy [00:05] <llrcombs> won't that be ridiculously huge? [00:05] <JEEB> well, depends [00:05] <JEEB> it will be big of course, as it is lossless [00:05] <JEEB> but whether or not it is bigger than the original is a separate matter [00:05] <JEEB> of course, MJPEG is not lossless so I might even leave it as-is :P [00:05] <llrcombs> true [00:06] <JEEB> oh, highest quality possible as in output and not lossless? [00:06] <JEEB> as in, "export" [00:06] <JEEB> (last stage of whatever workflow) [00:06] <JEEB> something that end users watch, and that isn't edited [00:06] <llrcombs> as in, highest quality I can get from this original without lossless [00:06] <JEEB> what are you going to be using this for? [00:07] <JEEB> end users? [00:07] <JEEB> editing? [00:07] <JEEB> as in, only for watching, or a working copy / whatever? [00:07] <llrcombs> sharing on Mediafire and YouTube (though I think no matter what my quality settings are, it won't make YouTube look any different) [00:07] <llrcombs> watching [00:07] <JEEB> k [00:07] <JEEB> then what I just said [00:08] <JEEB> highest crf that still looks good [00:08] <JEEB> and setting preset to the slowest you can take should give you compression [00:09] <llrcombs> http://www.youtube.com/watch?v=cUwjrIU9AsE&list=UU1qXejKCgpHeK-_DR8NDdkw&in… <-- I used -sameq and didn't specify crf, bitrate, etc... and ended up with this [00:09] <llrcombs> looks a little better not on YT, MOVs are here: http://www.mediafire.com/?w4d6rz648sg8y#19mj8p79zcjje [00:09] <JEEB> well, youtube'll re-encode your stuff in any case so to maximize profit there you might as well upload the original MJPEG there (or in case of you doing editing/whatever lossless H.264) [00:10] <llrcombs> not bad for YT, IMHO [00:10] <llrcombs> I'd have to reencapsulate the files for YT if I wanted to up the originals, as I'm pretty sure YT doesn't like THPs [00:11] <llrcombs> and I'm not sure if the mjpeg format here is standard [00:11] <JEEB> yeah, lossless H.264 via libx264 or ffvhuff or something [00:11] <JEEB> should be the "thing as-is" [00:12] <JEEB> also, -sameq's quality depends on the QPs of the original thing, and how they work on the output codec >_> When you mismatch codecs it becomes even more fun [00:13] <llrcombs> just out of curiosity now, as you seem to know a fair amount about codecs, can you identify what format these captions are: http://www.mediafire.com/?w4d6rz648sg8y#a4j6s38nq6mz2 [00:13] <llrcombs> I've been trying to figure them out; I've never seen binary captions before [00:13] <llrcombs> (mostly because one usually sees simple SRTs or SSAs) [00:14] <llrcombs> they were all compressed with LZ77, but the files up'd at that link are extracted [00:15] <JEEB> if this is out of some game there's a good chance they're in some weird proprietary format [00:15] <llrcombs> yeah, that's what I've been thinking [00:15] <llrcombs> ahh well [00:15] <llrcombs> the video files they correspond to are a weird proprietary format too, but ffmpeg supports it! [00:16] <JEEB> luckily enough :D [00:16] <llrcombs> they're THP files, which are used solely in GameCube + Wii games [00:16] <llrcombs> strangely-encapsulated not-quite-standard MJPEG with custom PCM audio [00:16] <JEEB> looking at the size of the captions I'll guess it's image-based [00:17] <llrcombs> I was guessing that it was in multiple languages, but image-based is possible too, I suppose [00:17] <JEEB> (easier for the game console to deal with too, since it doesn't have to render text) [00:19] <llrcombs> ahh well, it was worth a shot [00:19] <llrcombs> I can manually remake subs for them, there aren't that many lines [00:20] <JEEB> reminds me that I should see if I could continue the development of the ARIB caption app an internets friend of mine started [00:20] <JEEB> (used in Japanese digital TV) [00:21] <llrcombs> I've got a bug in trac right now about some rainbow artifacts in a few of the THP files on that page [00:21] <llrcombs> (most of the ones from FE9) [00:36] <dualbus> hi, I'm trying to stream live audio using ffserver; I'm capturing the audio from a network camera with a python script I made; the script outputs pcm_s16le, 4096 hz, 2 channels, and I'm piping that to ffmpeg [00:36] <dualbus> the exact command is " python -u audio.py | ffmpeg -vn -f s16le -codec pcm_s16le -sample_rate 4096 -channels 2 -i - -vn -f mp2 -codec libmp3lame -sample_rate 8000 -channels 2 http://localhost:8090/feed1.ffm" [00:37] <dualbus> http://dpaste.org/oEH9T/ [00:37] <relaxed> why -f mp2? [00:37] <dualbus> thats my ffserver.conf [00:38] <dualbus> relaxed: I don't really know, I've tried ogg/mp2 as an output format [00:38] <dualbus> and liblamemp3 and libvorbis as output acodec [00:39] <dualbus> but all the ffmpeg command does is to capture some blocks, and then it exits (breaking the pipe) [00:39] <dualbus> if I do the same command, but instead of pushing to the ffm location, I do record.mp3 it works correctly [00:40] <dualbus> so I'm guessing i'm doing something wrong in the ffserver config, but I don't know what [00:41] <dualbus> at first I thought it was my python script, since there is a delay between each output block (about 1sec) [00:42] <dualbus> but if I transcode directly to hard-drive it works correcly [00:48] <llrcombs> OHSHIT [00:48] <llrcombs> ohwait, this is freenote [00:48] <llrcombs> *freenode [00:48] <llrcombs> I forgot what net I was on [00:49] <llrcombs> I'm used to foonetic's netsplits, which take out about a quarter of whatever channel I'm in [01:23] <AkiraBot> wow 0.8.10 released [02:04] <PovAddict> does the mp4 container support embedded subtitles? [02:05] <microchip_> yes [02:05] <PovAddict> what codec should I use [02:05] <PovAddict> ? [02:06] <PovAddict> I have a .mp4 with h264 video and aac audio, and separately, a subtitle file in SRT format [02:06] <PovAddict> what codec should I tell ffmpeg to transcode the subtitles into? [02:08] <llrcombs> SSA? [02:09] <PovAddict> I thought both SSA and SRT were things created by the "community"? [02:10] <PovAddict> http://en.wikipedia.org/wiki/MPEG-4_Part_17 apparently this is what mpeg4 uses, does ffmpeg have any support for it? [02:13] <muken> there is no software supports mpeg-4 part17 (mp4s with OTI=0x08) [02:14] <PovAddict> "no software" is a bit of a strong statement, that wikipedia page says VLC can decode... [02:15] <muken> i think it is 3gpp timed text. timed text != mpeg-4 part17 [02:19] <muken> fourcc for mpeg-4 streaming text is 'mp4s', and for 3gpp timed text is 'tx3g'. i have never seen 'mp4s' case [02:20] <PovAddict> is there any subtitle format, embedded or separate-file, that is supported by Windows / WMP out of the box? [03:10] <shintaku> thank goodness... there's a channel [03:11] <shintaku> i'm trying to convert my massive 25GB movie into a smaller, sub 300MB mp4. the current resolution of the movie is 1680x1050. i'd like to half that.

[03:17] <PovAddict> yeah, trying without scaling first [03:17] <Arthur_D> how do I use ffprobe to display width&height of all video files in a folder? [03:18] <shintaku> same thing [03:18] <shintaku> w/o the -s [03:22] <PovAddict> I think that codec isn't supported by ffmpeg (yet) [03:24] <shintaku> poo [03:44] <CalimeroTeknik> how do I drop id3 tags when transcoding a file? [04:04] <shintaku> ok, converted to m4v w/ quicktime. i can now convert m4v to mp4. when i do, though, it looks like crap. any idea how to control quality. i tried -b 1200.

[04:19] <shintaku> yeah, just want it in mp4 [04:19] <PovAddict> it already is [04:20] <shintaku> m4v = mp4? [04:20] <shintaku> i don't know [04:20] <PovAddict> ok, try this: ffmpeg -i ~/Movies/iShowU-Capture2/Resources/iShowU-Capture2\ -\ Computer.m4v -vcodec copy out.mp4 [04:20] <shintaku> will do. thanks a bunch. [04:40] <shintaku> well, thanks a lot for your help, PoVAddict. heading to bed [05:49] <PovAddict> hi [05:49] <PovAddict> I have a 720x306 video which I want to transcode into a 16:9 DVD [05:51] <PovAddict> the original resolution is something like 2.35:1, so I need either padding or cropping to fit 16:9 [05:52] <PovAddict> however, if I use -target pal-dvd and pad it, ffmpeg first scales it from 720x306 to 720x576 and then pads *that* into 1024x576, which is not an allowed resolution in DVD [05:52] <PovAddict> dvdauthor somehow manages to create a .VOB but I don't think it's exactly compatible... [06:32] <PovAddict> took me a while but I managed to do what I wanted - wheew [06:59] <PovAddict> what's a reasonable bitrate for AC3 audio in a DVD? [07:00] <PovAddict> I don't know about ac3 quality, but using the default 448 kb/s for AC3 seems way overkill considering my source material is 160 kb/s MP3 [12:47] <mvip> I'm having a somewhat odd issue. I need to turn a sequence of one or two images into a video. Let's say I have image1.png, then I will need to turn that into a 7 second long video. Any points on how to best go about to do that? [12:48] <mvip> If i just do 'ffmpeg -i foo.png foo.mpg' that will generate a video that is a fraction of a second long [13:19] <mvip> For the record, the command is "ffmpeg -loop_input -t $SECONDS -r 1 -i $INPUT -s hd1080 -vcodec libx264 $OUTPUT" [17:55] <praedo> hello [17:56] <praedo> i use crf and -t to specify a time limit [17:56] <praedo> is it safe to predict the final bitrate of a 2 hour video considering the bitrate of a -t 60 chunk? [17:57] <JEEB> nothing is really safe if you encode a part of a thing, but you should get a better view if you encode 500-1500 frame chunks from various parts of the video [17:58] <JEEB> instead of just the first 60sec [17:58] <relaxed> is there a reason why you wouldn't use 2 pass instead? [18:03] <praedo> i don't know how [18:03] <praedo> i learned a command line which is gives quite a good quality [18:04] <praedo> and i understood that 2 pass would take a very long time [18:04] <praedo> ffmpeg -i file -deinterlace -vcodec libx264 -preset medium -crf 20 -threads 0 -acodec libfaac -aq 100 output.mp4 [18:04] <praedo> this is what i always use [18:04] <JEEB> if you want all encodes to have the same size for the same length (same average bitrate), then you use 2pass. If you just want to set quality, crf is what you want. [18:05] <praedo> but sometimes i have to repeat everything by changing 20 to 22 or 24 [18:05] <JEEB> also, some places do a crf 1st pass, and then set a bitrate and do a second pass if the crf encode is too big [18:05] <JEEB> (mostly video hosting sites) [18:06] <praedo> i want good quality for all lenghts with a result of 1300-1400 kbps [18:06] <JEEB> if you're that set for a bitrate [18:06] <JEEB> just use 2pass .-. [18:07] <praedo> okay... please tell me the basic commands [18:07] <praedo> with this example: [18:07] <praedo> ffmpeg -i file -deinterlace -vcodec libx264 -preset medium -crf 20 -threads 0 -acodec libfaac -aq 100 output.mp4 [18:07] <JEEB> -pass 1 -b:v 1400k for the first pass and -pass 2 -b:v 1400k for the second? [18:07] <JEEB> and preset should be set to the slowest you can take [18:07] <JEEB> http://mewiki.project357.com/wiki/X264_Settings#preset <- listing [18:07] <praedo> and both passes will take the same? [18:08] <JEEB> nah, second pass is faster [18:08] <JEEB> or well [18:08] <relaxed> also, remove -deinterlace and add -vf yadif [18:08] <JEEB> first pass will use faster settings [18:08] <JEEB> and second pass will be faster because it doesn't have to do frame type decisions [18:08] <JEEB> IIRC [18:08] <praedo> so i don't specify medium? i get a good quality with medium but it takes 8 hours for a 45min video [18:08] <praedo> pentium 4 [18:08] <llrcombs> JEEB: what's placebo, anyway? [18:08] <llrcombs> "supermegaincrediblyslow"? [18:09] <JEEB> llrcombs, everything up to eleven [18:09] <JEEB> yeah [18:09] <praedo> i want the same good quality i get with medium [18:09] <JEEB> for benchmarks [18:09] <praedo> how should the 2 pass commands look like [18:09] <praedo> ? [18:09] <llrcombs> JEEB: is it ever worthwhile? [18:09] <JEEB> praedo, if you don't specify medium it will get set as the default .-. [18:09] <JEEB> llrcombs, not really -- it's there for benchmarks [18:09] <JEEB> just like ultrafast [18:09] <llrcombs> JEEB: gotcha, so veryslow is usually your best bet if you can stand it [18:10] <JEEB> although some people really don't care as they get double-digit frame rates with SD content with placebo [18:10] <JEEB> lol [18:10] <JEEB> praedo, take away -crf and add -pass 1 -b:v 1400k for the first pass and -pass 2 -b:v 1400k for the second pass? [18:12] <praedo> good, and i don't specify medium? [18:12] <JEEB> medium is default .-. [18:12] <JEEB> so if you don't specify it, it will get automatically used [18:13] <llrcombs> I've heard conflicting statements on this: does setting the preset adjust video quality, filesize, or both? [18:13] <praedo> i see [18:13] <Mavrik> llrcombs, mostly quality, filesize is dependant on bitrate [18:14] <JEEB> llrcombs, it sets basically how much time is given to compression algorithms (read: how slow algorithms are used) [18:14] <JEEB> when you use crf it can affect the file size, with bitrate encoding it affects the quality [18:14] <relaxed> praedo: http://pastebin.com/raw.php?i=ERVw0xZd [18:15] <JEEB> (note that the quality that crf values give are not exactly the same between settings because different algorithms change how the crf value gets calculated) [18:18] <Mavrik> ah. [20:07] <XeonBloomfield> Hello [20:07] <XeonBloomfield> "-acodec vorbis" and "-acodec libvorbis" are two different things, right? [20:18] <saste> XeonBloomfield: vorbis -> internal codec, libvorbis -> wrapper around libvorbis [20:19] <XeonBloomfield> saste: I see [20:19] <XeonBloomfield> saste: vorbis (internal) is saying little... to ass... [20:20] <XeonBloomfield> saste: it convert about 5 times faster, but quality is terrible [20:27] <praedo> JEEB, why -y in the 2nd pass? that will overwrite the file... so where are the stats of the 1st pass stored? [20:28] <JEEB> I haven't said ANYTHING about -y >_> [20:28] <JEEB> ask the guy who actually gave you that [20:28] Action: JEEB smacks praedo for highlighting the wrong guy [20:28] <praedo> http://pastebin.com/raw.php?i=ERVw0xZd [20:28] <praedo> isn't that correct? [20:28] <JEEB> yes, that is not me [20:29] <praedo> i know [20:29] <praedo> please have a look [20:29] <praedo> isn't -y needed then? [20:29] <JEEB> I don't care, I am watching video now so you can take the lower priority [20:30] <JEEB> and the -y is probably in case you are actually outputting the 1st pass into a file instead of NUL or /dev/null [20:30] <JEEB> that's all [20:42] <diegoviola> hi [20:43] <diegoviola> i want to extract part of some movie from 00:03:15 to 00:03:30, and encode this to ogg/theora/webm into another file, is this possible with ffmpeg? [20:52] <falip> what is a standard video and audio codec for FLV? [20:52] <Hyperi> New one is pretty much the same as mp4 iirc [20:53] <Hyperi> falip: http://en.wikipedia.org/wiki/Flash_Video [20:53] <falip> what about old one? [20:53] <JEEB> falip, FLV can take VP3, VP62, Sorenson Spark, H.264 IIRC video-wise [20:53] <JEEB> audio wise mp3, aac at least [20:53] <JEEB> probably more [20:53] <falip> ta [20:53] <Hyperi> Oh right, I only use H.264 in my mp4 FLV [20:54] <Hyperi> As it works for HTML5 browsers aswell nicely :P [20:54] <Hyperi> <video> tag that is, and not restricted to Flash [20:54] <JEEB> mp4 is what the container format in mpeg-4 specs is normally called .-. [20:54] <falip> does ffmpeg set a container format based on extension, or is there a special switch? [20:54] <JEEB> there is a format switch IIRC as well [20:55] <Hyperi> like -vcodec parameter? :> [20:55] <JEEB> nah, that's video codec [20:55] <JEEB> but yeah, similar switch [20:55] <falip> JEEB: there is -formats but that just lists formats. [20:56] <JEEB> yeah [20:56] <JEEB> I don't remember what the format setting switch was :P [20:56] Action: JEEB usually sets the output file name in a way that ffmpeg can guess [20:57] <Hyperi> 'man ffmpeg' might help :P [20:58] <ioni> jeeB did you find out the problem? [20:59] <JEEB> ioni, nope -- I don't have access to the box and helping the guy was too herp derp [20:59] <JEEB> http://ffmpeg.org/ffmpeg.html is another good place to check stuff :3 [20:59] <ioni> k [20:59] <falip> how do you distinguish between mpeg the container format and the codec? [20:59] <falip> is it only a container format? [20:59] <JEEB> uhh [21:00] <JEEB> there are lots and lots of mpeg-specified container formats :< [21:00] <falip> ah I see [21:00] <JEEB> mpeg-ts , mpeg-ps , iso media | mp4 [21:00] <JEEB> etc. etc. [21:00] <JEEB> usually they are distinguished by extensions, but of course that isn't always completely correct [21:01] <JEEB> (someone can make an mkv file f.ex. and then rename it avi) [21:02] <falip> there is such a thing as a mpeg audio codec(mp3), but no mpeg video codec is there? only codecs for the mpeg video format [21:03] <falip> i mean [21:03] <falip> there is such a thing as a mpeg audio codec(mp3), but no mpeg video codec is there? only codecs for the mpeg container format [21:03] <falip> actually i suppose there is like mpeg1video [21:04] <falip> so is mpeg set of container formats, and video codecs, and audio codecs? [21:05] <falip> set=a set [21:08] <JEEB> mpeg is an entity that does specifications of formats [21:08] <JEEB> those can be a lot of stuff [21:08] <JEEB> ranging from audio, video codecs f.ex. to containers and other similar stuff [21:09] <JEEB> some mpeg video codecs: mpeg-1, mpeg-2, mpeg-4 part 2, mpeg-4 part 10 (also called H.264/AVC) [21:11] <JEEB> audio wise you have: mpeg-1 layer 1, layer 2, layer 3 (layer 3 is also what you call "mp3") [21:11] <JEEB> and then some others, including ALS in mpeg-4 [21:12] <JEEB> (ALS is part of mpeg-4 part 3, which also contains a lot of other formats .-. ) [21:25] <falip> thanks btw I found a force format option -f fmt [21:29] <JEEB> yeah [21:29] <JEEB> that was it [21:38] <diegoviola> anyone please? [21:40] <sacarasc> diegoviola: -ss and -t [21:40] <diegoviola> sacarasc: thanks [21:41] <diegoviola> can i encode h264/mkv to webm? [21:41] <diegoviola> with ffmpeg [21:45] <sacarasc> Yes. [21:46] <diegoviola> ok ty [22:10] <falip> why do I get this error [22:10] <falip> C:\>ffmpeg -i w.flv -vcodec svq1 -acodec libmp3lame w2.flv [22:10] <falip> it says video codec not compatible with flv [22:10] <falip> but surely sorenson spark is [22:10] <falip> compatible with flv [22:16] <JEEB> falip, then your ffmpeg version just doesn't support muxing it there or something .-. [22:16] <JEEB> I'd personally use H.264/AAC within flv tho [22:22] <falip> what about for mp4? [22:23] <falip> would you do -vcodec mpeg4 -acodec libmp3lame ? [22:24] <JEEB> nope [22:24] <JEEB> at least if I wanted compression/good control of quality [22:24] <JEEB> lol [22:24] <JEEB> libx264 <3 [22:25] <falip> when do you use libx264 and when h264? [22:26] <JEEB> h264 is the H.264 decoder, libx264 is a mighty good H.264 encoding library [22:26] <falip> howcome one only specifies one then when doing -vcodec? [22:26] <falip> aren't both a decoder and encoder necessary to convert from one to another? [22:27] <JEEB> yes, but the decoder is usually automatically used if the format is identified [22:27] <sacarasc> If you want to use h264 for decoder, you can use -vcodec h264 in the input section. [22:27] <JEEB> ^ [22:27] <JEEB> pretty much "set -vcodec before -i", right? [22:27] <JEEB> after -i it becomes the encoder selection [22:28] <falip> is it better to do -ss and -t before -t or after? [22:28] <falip> I mean before -i or after? [22:31] <falip> i think i got it.. as an output is slower but more accurate [22:31] <falip> for -ss anyway is what i've got noted down from some time. [22:31] <falip> to do with keyframe or something. like whether it cuts at that. [22:36] <falip> I just tried to convert an mpg to mp4, libx264 and I got the errors [22:36] <falip> [libx264 @ 01e0d010] broken ffmpeg default settings detected [22:36] <falip> [libx264 @ 01e0d010] use an encoding preset (vpre) [22:37] <JEEB> you have an old ffmpeg >_> [22:37] <JEEB> get a new one [22:37] <falip> ok but out of interest what would I have done? [22:37] <JEEB> back then you had to use the ffmpeg's presets that would override ffmpeg's then-broken defaults [22:37] <JEEB> now ffmpeg uses libx264's defaults [22:38] <JEEB> and has -preset to set libx264's presets [22:38] <falip> what defaults was it set to back then? [22:38] <JEEB> Something Quite Awful [22:38] <JEEB> awful enough to make libx264 block their usage :P [22:38] <falip> was it the settings for another codec or something? [22:38] <JEEB> well [22:39] <JEEB> they pretty much had one line of defaults for ALL codecs [22:39] <falip> heh [22:39] <JEEB> I think it was either 200kbps or 300kbps, with some very basic features used >_> [22:39] <falip> so now it autodetects? [22:39] <falip> or does it piss off all the other codecs? [22:40] <falip> piss off = slang, for annoy [22:40] <JEEB> nah, now it just uses libx264's defaults for libx264 [22:40] <falip> british slang [22:40] <JEEB> which is the sane thing to do [22:40] <JEEB> no idea about other codecs [22:40] <falip> k [22:40] <JEEB> also, overall libx264 usage got a lot easier [22:41] <JEEB> you got -preset to set libx264's presets, -profile:v to set libx264's profile, and -level for libx264's level setting [22:42] <JEEB> before those additions got in, I would've never used ffmpeg to encode libx264 .-. [22:42] <JEEB> because you basically had to write down the settings in a very herpy derpy way [22:43] <diegoviola> ffmpeg is awesome [22:43] <diegoviola> -t and -ss worked great for me, thank you all [22:44] <Mavrik> JEEB, is it -profile:v now? :) [22:45] <JEEB> Mavrik, just setting -profile works too unless you're using aac encoding >_> [22:45] <JEEB> because nowadays profile tries to get applied to both, and aac encoding seems to have "profile" [22:45] <JEEB> thus, setting -profile:v will only have it affect video [22:45] <Mavrik> yeah, I thought it was "-vprofile" so I'mnot really sure which is the "last" version :P [22:46] <JEEB> -profile:v seems to be the final way [22:46] <JEEB> (for now) [22:46] <Mavrik> ^^ [22:47] <Mavrik> eh, I'll deal with it when my tests fail with -vprofile -_- [22:47] <JEEB> yeh [22:48] <huglester> guys where I can find information on how to put watermark over video? I'm using 0.9.. so searchign for fresh docs... I trie to look in the archive, but it has some files which probably need to be compiled somehow to open them [22:49] <Mavrik> huglester, http://ffmpeg.org/libavfilter.html [22:49] <huglester> ah.. so it's done via libavfilter? thanks [22:50] <Mavrik> huglester, yeah, it's a video filter [22:50] <JEEB> the overlay video filter [22:50] <JEEB> IIRC [22:50] <Mavrik> huglester, you're looking for the overlay filter [22:51] <Mavrik> oh, I'm late -_- [22:51] <huglester> thank you :) [22:51] <huglester> Yeah I was going to ask it.. because could not find the word 'watermark' in the docs [22:51] <huglester> but after I searched for '.png' I foudn out about overlay :))) [22:52] <falip> I think I just got the ffmpeg command to convert an mpg to mp4 -vcodec libx264 without any -profile or -level [22:53] <JEEB> sure [22:53] <JEEB> you don't need to set those unless you are encoding for some limit [22:53] <JEEB> just make sure you have a new'ish ffmpeg and you'll start getting sane settings >_> [22:53] <falip> yeah this is the latest one [22:53] <falip> the previous one gave the error [22:53] <JEEB> yup [22:53] <falip> when you say some limit, what kind of limit? [22:54] <JEEB> hardware devices, etc. [22:54] <JEEB> profiles = feature limits [22:54] <JEEB> level = memory limits [22:54] <falip> oh ok [22:54] <JEEB> http://mewiki.project357.com/wiki/X264_Settings#preset <- also, a listing for libx264's presets [22:54] <JEEB> (basically use the slowest preset you can take speed-wise :)) [22:54] <falip> is there anything that lists recommended video and audio codecs for each common container format? [22:55] <JEEB> not that I think [22:55] <falip> when ffmpeg wasn't good for libx264, what did you use? [22:56] <Mavrik> falip, instead of checking which codec for container, rather check which codec will work best for content and target devices and then choose container accordingly [22:56] <JEEB> x264's command line encoder [22:56] <JEEB> I still am better with controlling x264cli than libx264 via ffmpeg :D [22:57] <falip> Mavrik: well i can find like one piece of software isn't good at playing a file so I need to convert it to something else [22:58] <Mavrik> *shrug* [22:58] <Mavrik> pretty much anything can play H.264/LC-AAC in MP4 nowdays, so that's a very safe bet [22:58] <falip> they all seem just as good in terms of quality, when they play! [22:58] <Mavrik> unless you have some special demands [22:59] <falip> well, i have some old windows machines with a WMP that won't see mp4 [22:59] <falip> and i have some software to split videos, that won't play mp4 it seems [22:59] <falip> xilinx, they have a piece of software for combining them that works properly really well [22:59] <falip> so i like to use their splitter too [23:00] <Mavrik> huh [23:00] <Mavrik> then you'll have to check what those WMPs can play [23:00] <falip> I mean xilisoft is the software. [23:00] <falip> WMP=windows media player [23:00] <falip> no WMPs ;-) [23:01] <falip> sometimes I play things in an early WMP that won't accept mp4 at all. [23:03] <huglester> guys, anything here does seem invalid for you here? /usr/local/bin/ffmpeg -y -i 4_4734464ac1fc386a1a79c4f036e2e7af.avi_240.mp4 -vf "movie=watermark_video.png [logo]; [in][logo] overlay=10:main_h-overlay_h-10 [out]" watermark.mp4 [23:04] <huglester> I am hetting these errors: http://d.pr/iD3X [23:06] <Mavrik> hmm... either you don't have png support compiled into ffmpeg or you confused it with it [23:07] <huglester> I'll just try try jpeg now, to see if there are any changes [23:07] <Mavrik> huglester, check ffmpeg -codecs to see if your ffmpeg supports png [23:10] <huglester> Mavrik: seems no :( giving .jpg file worked! [23:10] <huglester> need to search on how to enable png support [23:11] <huglester> Thank you very much [23:14] <huglester> Mavrik: do I need ffmpeg with png support, or avfilter..? [23:16] <falip> what does this line mean? [23:16] <falip> EV libx264 libx264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 [23:16] <falip> encoder, video OK [23:16] <falip> but what's the H.264 / AVC thing mean? [23:17] <falip> AVC is a different video codec, so what does it mean in that context? [23:17] <microchip_> falip: AVC = advanced video coding, which is another name for H.264 [23:23] <falip> and sorenson is another name for H.263? [23:23] <JEEB> nah, sorenson spark is a H.263-based codec [23:23] <microchip_> yes, although it's a modification of .263 [23:23] <microchip_> H.263* [23:23] <JEEB> http://wiki.multimedia.cx/index.php?title=Sorenson_Spark [23:28] <falip> so when -codecs has lines like this [23:28] <falip> DEVSD flv Flash Video (FLV) / Sorenson Spark / Sorenson H.263 [23:28] <falip> EV libx264 libx264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 [23:28] <falip> the right hand side is a mix really [23:29] <falip> 'cos for the libx264 line AVC is another name for H.264 [23:29] <falip> but for the flash line, Sorenson is not another name for flash [23:29] <falip> so what does that right hand side set out to achieve? [23:30] <falip> also is there a quick way to cut 5 seconds off a long video in ffmpeg? [23:31] <falip> using -ss 0 -t .. takes quite a while. [23:31] <falip> i'd rather have a cut function maybe it'd be quicker [23:31] <falip> than an extract function [23:33] <JEEB> sorenson spark was IIRC the first codec in 'flv' flash video, no? [23:33] <JEEB> thus it's like mpeg4 [23:33] <huglester> I'm lost :( how do I compile png support in? maybe I need to compile ffmpeg with: --enable-decoder=png ? [23:34] <JEEB> which is really mpeg-4 part 2 [23:34] <JEEB> (the first video codec in mpeg-4) [23:40] <diegoviola> how do i tell ffmpeg not to encode audio while encoding some video [23:41] <falip> Is AVC a name for the encoder and the decoder? [23:41] <sacarasc> diegoviola: -an or -acodec copy [23:41] <diegoviola> sacarasc: i mean i don't want audio at all in the output file [23:41] <diegoviola> i want to exclude it [23:41] <sacarasc> Then the first one. [23:41] <diegoviola> ty [23:42] <JEEB> falip, the video format in itself is called MPEG-4 Part 10 AVC / ITU-T H.264 or whatever [23:42] <JEEB> the name of the decoder in ffmpeg is h264 [23:42] <JEEB> and the encoder available to encode in that format is libx264 [23:43] <falip> diegoviola: -an means no audio [23:43] <falip> if i recall. and -vn means no video [23:44] <diegoviola> falip: thanks [23:44] <falip> wow, so h264 and h.264 are different things, such fiddly syntax! [23:44] <microchip_> falip: no they're not [23:44] <JEEB> nope, ffmpeg's codec's name just doesn't have the dot there :P [23:45] <falip> yeah JEEB I call that fiddly syntax! [23:46] <JEEB> well, it's usual to drop stuff like that on command line usually .-. [23:46] <falip> and do any decoders have a name like h264.. or only libx264? [23:47] <falip> doh i mean [23:47] <falip> and do any encoders have a name like h264.. or only libx264? [23:47] <JEEB> external encoders have a name like "libSOMETHING" [23:47] <microchip_> falip: nope, only libx264 [23:47] <JEEB> internal encoders/decoders have a name set inside ffmpeg [23:47] <falip> well, libmp3lame-yes. But mp2 is just mp2. [23:48] <JEEB> yes, because it's internal [23:48] <JEEB> lib = library [23:48] <falip> ok [23:48] <falip> so i guess the ones that were around when ffmpeg was built! [23:48] <falip> and the others are external? [23:48] <microchip_> falip: whay do you even care how it's called? just use it :P [23:49] <microchip_> falip: it has little to do with when ffmpeg was built [23:49] <falip> microchip_: you mean just call it ;-) [23:49] <microchip_> falip: it has to do with whether there's an ffmpeg implementation of a specific codec or not [23:50] <falip> well maybe initially they reinvented the wheel then later they decided to use libraries more. [23:51] <falip> though their philosophy as to which they made internal and which they made external isn't important and certainly wouldn't be of interest to you microchip_ if you think even what it is called doesn't matter much!

[00:00] <ubitux> anyway, doesn't matter [00:00] <Compn> fedora has some crazy security things [00:00] <Compn> used to affect mplayer even [00:00] <Compn> or was that redhat [00:00] <Compn> hmm [00:01] <gnafu> I haven't had any issues with SELinux for the last few releases at least.

[03:06] <ubitux> michaelni: i think "amongth" is not a correct english word [03:07] <ubitux> maybe you wanted to use "among" (or eventually "amongst" which seem less common) [03:13] <michaelni> ubitux, locally fixed, thx [03:43] <durandal11707> hmm rsync server is sending crap to me [03:46] <ubitux> seriously& wtf: http://stackoverflow.com/questions/5637178/clang-2-9-crt1-not-found-error [03:46] <ubitux> it's been 1 hour i'm trying to understand why clang isn't able to build a single binary [03:46] <ubitux> i needed to add the gcc version in that list& [04:28] <ubitux> michaelni: i think i won't use ioc soon [04:28] <ubitux> it just ate my 6GB of ram in a few seconds running one of the fate test [04:28] <ubitux> so i don't think it's wise to use it on my box :p [04:30] <ubitux> i may be doing something wrong or hiting an incompatibility somewhere [04:30] <ubitux> but well, i don't have much time for this, i already gave it too much time [04:49] <durandal11707> libcdio input format is missing long name [15:21] <cbsrobot> ubitux ping [16:05] <ubitux> cbsrobot: pong [16:05] <cbsrobot> ubitux: just a (maybe stupid) question [16:05] <cbsrobot> how should I pass the timecodecontext from the decode to the encoder ? [16:07] <ubitux> i don't know at all :) [16:07] <cbsrobot> and should we add a dummy codec for timecode streams ? [16:07] <cbsrobot> lol [16:09] <cbsrobot> and I guesst the timecode api is not stable yet [16:09] <cbsrobot> ok to change the the arguments for [avpriv,ff]_framenum_to_smtpe_timecode ? [16:14] <ubitux> do you really need to change that? [16:14] <ubitux> changing it means deprecating the old one [16:14] <ubitux> what do you need to change? [16:22] <cbsrobot> Im ff_timecode I replaced the drop with a flags [16:23] <cbsrobot> and instead of submitting drop to them I need to submit flags [16:24] <cbsrobot> but I can also add a workaround [16:25] <ubitux> ah yes i wanted to do that for the new api [16:26] <cbsrobot> so what do you think ? [16:26] <ubitux> well the best things to do is to rewrite the timecode api in lavu properly [16:27] <ubitux> i will work on this starting monday [16:27] <cbsrobot> ok [16:27] <cbsrobot> I'll send a WIP to the ML [16:27] <ubitux> atm i don't have time for this unfortunately [16:27] <ubitux> yes good idea [16:28] <cbsrobot> ok [16:28] <ubitux> feel free to change the prototype for the WIP [16:28] <cbsrobot> ok [16:31] <cbsrobot> btw - mov can add a fontname (size etc.) to the timecode atom [16:31] <ubitux> yes [16:31] <cbsrobot> what to do with it ? [16:31] <cbsrobot> missude metadata ? [16:31] <cbsrobot> *misuse [16:31] <ubitux> i don't really know& [16:32] <ubitux> in the best world a timecode track just like subtitles should be generated [16:32] <ubitux> with the style set with ass tags [16:33] <ubitux> but we are not at that point yet, i'd ignore it& [16:33] <ubitux> except if you need to keep it in transcode maybe [16:34] <cbsrobot> well yes [16:35] <cbsrobot> two more things to consider when doing transcode is the udta tag for the timecode track [16:35] <cbsrobot> it's used for the name of the track [16:35] <cbsrobot> I think it's used by editing applications like final cut to be able to match the timecode type [16:36] <cbsrobot> like auxTC, sourceTC, etc [16:37] <cbsrobot> and there seems to be the tref tag on the video track referencing to the timecode tracks [16:38] <cbsrobot> but I'm not sure what happens if they are ignored [16:39] <ubitux> i really don't know much about the mov [16:39] <ubitux> i won't be able to help a lot [16:43] <NapHtaKeRoSene> i have invented area map in 8 hours, good time? [16:58] <ubitux> can anyone try "make libavutil/eval-test && valgrind ./libavutil/eval-test" and tell me if there are valgrind failures? [16:58] <ubitux> i don't understand the issue here, and i suspect a valgrind or libc bug [16:59] <ubitux> though, i'm not able to reproduce it in a simpler .c [17:28] <ubitux> mmh, might be related to http://sourceware.org/bugzilla/show_bug.cgi?id=12424 [17:39] <j-b> is Carl around? [17:44] <av500> on irc? [17:44] <av500> rarely I would say [17:56] <j-b> crap [17:57] <ubitux> my logs say he came only once here in 2011 [17:57] <ubitux> for exactly 3 minutes [17:58] <av500> j-b: you lost email access? [17:59] <j-b> yes [18:01] <av500> hadopi? [18:01] <j-b> yes [18:02] <av500> j-b: if you are on the run, I have friends in paris that could hide you [18:02] <j-b> not yet [18:02] <j-b> source code of BD+ is still hidden [18:02] <j-b> and the keys are still on http://vlc-bluray.whoknowsmy.name/ [18:04] <funman> what's the plan for revealing BD+ source btw? [18:12] <j-b> having someone test it [18:12] <j-b> and fix it [18:12] <j-b> separate the sensitive data [18:21] Action: JEEB wonders if any of his discs actually contain BD+ [18:23] <gnafu> Wait, there's progress being made on playing back BD+ discs? Awesome! [18:24] <gnafu> The day I can play most or all commercial Blu-ray discs in VLC is the day I buy a BD-ROM drive for my computer and start buying at least a few Blu-rays. [18:26] <JEEB> I already buy stuff I like, or what I find cheaply. But I don't have a drive .-. I get the data of those blu-ray discs in other ways. [18:26] <Compn> j-b : i can mail carl if you want ? [18:27] <j-b> Compn: you're nice [18:27] <j-b> I will do it [18:27] Action: Compn asks the dumb questions :) [18:28] <gnafu> JEEB: Yeah, I'll probably start buying some soon anyway. There are certain movies I know will really benefit from HD, and then other Blu-rays that are just so darn cheap. [18:29] <JEEB> yeh [18:29] <gnafu> I just got a projector, so I'll probably be buying a dedicated player soon anyway. Right now, I just have an Oppo 971H (which is excellent for upscaling DVDs, but it's not the same). [18:30] <Compn> encryption schemes only hurt paying customers [18:30] <JEEB> indeed [18:30] <Compn> i will not buy into something that affects my use of it :P [18:31] Action: Compn is blu free! [18:31] <j-b> http://source.ffmpeg.org/?p=libaacs.git;a=summary [18:32] <gnafu> Compn: That's largely how I feel, but it's getting hard to resist now that I have a 70" HD display (and a nice 1080p monitor for my computer as well)... [18:33] <gnafu> But I'm trying to hold out for an open source implementation, allowing me to have my cake (commercial Blu-ray discs) and eat it too (watch it, decode it, and play with it in Linux). [18:35] <funman> iiuc libbd+ contains mandatory powerdvd9 memdumps, that's all taht is "sensitive" [18:37] <j-b> dvd8 [18:40] <Compn> well [18:40] <Compn> j-b : you could always tell those secret blu key guys to submit patches to mplayer [18:40] <Compn> mplayer isnt afraid of anything :D [18:41] <j-b> this is not like 10 years ago, you know [18:41] <Compn> is it worse? [18:41] <gnafu> I think mplayer is a pretty cool guy. Eh fights copy protection and doesnt afraid of anything. [18:42] <j-b> Compn: yes, way worse [18:42] <j-b> Compn: to host it correctly, you need now servers outside of USA, EU, Russia and Japan [18:43] <Compn> ah, software patents [18:43] <j-b> no [18:43] <j-b> DRM breakage [18:43] <Compn> ah [18:43] <Compn> i thought it was still legal in usa for interoperability [18:43] <j-b> no [18:43] <j-b> Compn: shipping 30M/month binaries libdvdcss, I know the mess [18:43] <Compn> i guess that one key showed that was incorrect :\ [18:43] <Compn> doh [18:43] <j-b> and Sony will fight [18:43] <Compn> yeah, you know best :) [18:43] <j-b> they already told me [18:48] <Compn> i remember they tried to harass digg about that aacs key [18:49] <Compn> are there distros that even accept libdvdcss ? [18:49] <funman> what we (including i) don't get is how libaacs is different from libdvdcss [18:49] <funman> and libbd+ [18:50] <funman> Compn: iirc altlinux (russian distro) did/does [18:53] <gnafu> funman: Well, the content on Blu-ray discs is, like, 6 times the resolution of DVD content, so it's at least 6 times more important to protect it. [18:56] <funman> so i can go and sell VHS copies in front of MPAA offices? [18:56] <funman> well i hope oyu're not serious [18:56] <Compn> that would only make sense if you could divide by zero [18:56] <Compn> funman [18:56] <funman> if you sell drugs your sentence isn't proportional to the amount you sold [18:57] <funman> video content isn't worth protecting only at some resolution [18:57] <funman> to me libaacs + libbd+ = libdvdcss, same same [18:57] <Compn> and yes that was a joke [18:58] <Compn> gnafu also did the mplayer doesnt afraid of anything meme :) [18:58] <funman> sorry i didnt catch it - bad day [18:58] <Compn> j-b : anyways, lots of people want to help if they can with bluray stuff. just let us know if we can. [18:58] Action: Compn goes afk [19:00] <funman> Compn: j-b: first thing would be release code to select peoples remove "sensitive" stuff, then release non-working sources so everyone can improve on it [19:02] Action: ubitux kicks CIA-31 [19:02] <CIA-31> ow [19:04] <gnafu> funman: General rule of thumb for interpreting what I say is that I'm probably not serious ;D. [19:05] <gnafu> Especially if I use one or more smilies, or if I put "like" in the middle of a sentence like a valley girl :-).

[19:51] <CIA-31> ffmpeg: Signed-off-by: Reimar Döffinger <Reimar.Doeffinger(a)gmx.de> [20:17] <ubitux> it seems running all the valgrind tests doesn't take 1-2hours actually, but more like 6 or 8 [20:17] <ubitux> :( [21:53] <uau> michaelni: IIRC libpostproc is not quite "100% the same ABI" in 51 and 52 [21:54] <uau> there was a help string symbol that changed, IIRC from a pointer to a string to the string itself [21:55] <uau> yes ffmpeg still has this in postprocess.h: [21:55] <uau> extern const char *const pp_help; ///< a simple help text [21:55] <uau> #else [21:55] <uau> extern const char pp_help[]; ///< a simple help text [21:57] <ohsix> what are the implications of the constness change to code that is built against the old version [21:58] <michaelni> uau, i had not realized that this changed :( [21:58] <uau> ohsix: what "constness change"? you must have misread that [21:59] <ohsix> * pp_help and pp_help[] are the same, *const pp_help and pp_help[] are not [22:00] <uau> ohsix: you're confused [22:01] <ohsix> and? [22:02] <ohsix> i guess if it's in front of const it's not the same, nevermind [22:04] <ohsix> or is it [22:04] <beastd> if i am not mistaken it is an array-vs-pointer change [22:04] <ohsix> that's what cdecl says [22:07] <uau> ohsix: that difference actually mattered for mplayer2 code (and likely for mplayer 1, as the relevant part came from it) [22:07] <ohsix> but it doesn'ttt [22:08] <ohsix> an array declared like that is equivalent to a pointer [22:08] <ohsix> it just changes the constness of the reference [22:08] <uau> there was a global constant help string struct where one element was initialized to "&pp_help" [22:09] <ohsix> what jerks [22:09] <uau> in postproc 51 that means pointer to the pointer [22:09] <uau> in postproc 52 that means pointer to the first character of the string [22:09] <uau> definitely completely different meanings [22:10] <ohsix> that's an api change though, unless you have something writing the strings (that's discernable at compile time, all bets for constness are off at runtime), not an abi change [22:10] <uau> it is an abi change [22:10] <uau> in 51 abi the symbol "pp_help" is resolved to point to the first byte of a pointer [22:11] <uau> in 52 abi the symbol "pp_help" is resolved to point to the first byte of a string [22:11] <uau> definitely different abi [22:11] <ohsix> oh i see [22:11] <ohsix> pointer size change since it's char [22:11] <uau> you're still missing the biggest difference [22:12] <ohsix> i'm not missing the one that drew me to the wrong conclusion now, though [22:12] <uau> the api actually changed "less" in a way; something like say "pp_help[0]" would still give the same result on an API level, even though the underlying ABI changed [22:13] <uau> in 51 abi that'd mean "read pointer from the location given by pp_help, then read character from the location given by the pointer" [22:13] <uau> in 52 abive that'd mean "read character from the location given by the pp_help symbol" [22:15] <beastd> ohsix: what makes you think it is equivalent to a pointer? the syntax deceives you into using it like pointer/array but the binary interface is quite a different thing, isn't it? [22:16] <ohsix> beastd: yea the binary interface is what i was thinking of, and assuming char and the native pointer size were wquivalent [22:16] <beastd> ohsix: you are missing the (now missing) indirection [22:17] <ohsix> ok [22:17] <michaelni> i guess the best way to resolve this in 0.9.2 would be to compile & install postproc for both ABIs [22:20] <iive> i actually wonder how the underling assembler have changed. [22:20] <michaelni> maybe someone has a better idea ... [22:22] <uau> iive: you mean when using the symbol? [22:23] <iive> yes. I would assume that in the [] case the linker would try to overwrite the address in the calling binary. [22:23] <uau> "char *p = pp_help;" in 51 this would resolve the symbol pp_help (which could have been done at link time, or could result in a call to resolve dynamic linking), and then would do a load from the pp_help address [22:24] <uau> in 52 it would resolve the symbol pp_help, and that itself would be the result [22:41] <iive> michaelni: building and installing two separate and almost identical libraries sounds like horrible idea. especially for such small difference. And then you'd have the same problem for the headers and picking the right library at link time... [22:42] <michaelni> iive, the headers are a problem :( [22:44] <michaelni> i guess that leaves adding a switch to configure so the person compiling can choose which he wants [22:47] <iive> there is another solution, you can make the pointer a null one. it would also constitute an empty string. still I'm not sure it NULL pointer won't break the programs that use it without checking. [22:48] <iive> it NULL/if NULL [22:48] <iive> and is horrible bit of hackery.... [23:19] <funman> any clue on a win64 application using ffmpeg's dxva2? [23:19] <funman> i know it's broken in vlc/win64 but no idea if it's on ffmpeg or vlc side [23:20] <funman> and WMP works [23:40] <Compn> funman : dumb question, why not just use 32bit ? [23:43] <funman> Compn: 64 is 2 times better than 32!! [23:43] <Compn> when it works. [23:43] <funman> more seriously 32bits work fine [23:43] <Compn> ah [23:43] <funman> the question could have been "why using windows" :) [23:44] <Compn> well since you cant really use ffmpeg dxva2 by itself, its going to be difficult to figure if its ffmpeg or vlc [23:44] <funman> well the bug is somewhere [23:44] <Compn> and since its pretty much only vlc (and possibly mpc-ht) using dxva2, if they fix it, they will fix ffmpeg too ;P [23:44] <funman> and debugging tools for windows are crap when they exist at all [23:44] <funman> yeah [23:44] <funman> they = me in this case [23:44] <Compn> oh ok [23:45] <Compn> so your question is [23:45] <Compn> how do you debug a win64 mingw app ? [23:45] <kierank> gdb [23:45] <Compn> right [23:45] <funman> do you guys have gdb/mingw skills? [23:46] <Compn> add in a bunch of printfs' to vlc and ffmpeg and see how far it gets [23:46] <funman> well in fact i have a backtrace [23:46] <Compn> gdb works fine on mingw, well, on 32bit, i havent tested 64 but it should be the same. [23:46] <funman> but only function names, no lines [23:46] <Compn> did you compile everything with debug symbols ? [23:46] <funman> and vlc use DLLs so it's a bit special [23:46] <funman> yeah [23:46] <Compn> but if you paste the backtrace at least we can try to figure where its crashing [23:47] <Compn> even without lines, maybe [23:47] <funman> are you interested in helping me with that? i'll reboot to windows [23:47] <Compn> i am trying to figure out who is the mingw64 master [23:48] <Compn> kshawkeye / zeranoe and whoever added dxva2 to ffmpeg [23:48] <Compn> who else does 64mingw [23:48] Action: Compn thinks [23:48] <funman> ramiro [23:49] <Compn> Gianluigi Tiesi also does a lot of mplayer mingw stuff [23:50] <Compn> reimar plays with it i think [23:51] <Compn> well you can always boot to windows and ask [23:51] <Compn> we can try :) [23:53] <funman> ok let's see [00:00] --- Sat Jan 14 2012

[02:50] <kode54> is there any way to convert a left/right stereo video pair to a side by side video without using stupid hacks like converting all the videos to image files and assembling them with imagemagick? [02:50] <kode54> I'd rather just use avisynth for that, except that's not portable [03:08] <iive> kode54: ffmpeg support multiple input file and video filter system that can handle parallel branches. [03:08] <iive> but i'm not sure about the exact syntax. [03:19] <kode54> I see video filter options [03:19] <kode54> what would be really handy would be if the input specifier could specify a stream id from existing inputs [03:19] <kode54> since the input video I have is an AVI file with two video streams [03:20] <kode54> ah, split option [03:21] <kode54> no [03:26] <kode54> http://ffmpeg-users.933282.n4.nabble.com/libavfilter-multiple-input-td32373… [03:26] <kode54> I see nobody answered it [03:30] <ubitux> -f lavfi -i "movie=a.mp4 [a]; movie=b.mp4 [b]; [a][b] overlay=..." ? [03:46] <kode54> got it [03:46] <llrcombs> anyone here know anything about weird caption formats? [03:46] <kode54> ffmpeg -i HNI_0043.AVI -map 0:0 -map 0:1 -vf "[in]pad=iw*2:0:0:0:black, [T1]overlay=480:0, scale=0:ih*2[out]; movie=HNI_0043.AVI:si=2[T1]" -acodec libmp3lame -ab 192k -vcodec libx264 -crf 20 HNI_0043_sxs.mkv [03:47] <kode54> to turn 3DS video into side by side format suitable for youtube [03:47] <kode54> 3DS is AVI, with two 480x240 MJPEG streams sandwiching a 16KHz mono IMA ADPCM stream [03:48] <kode54> video filter trickery to overlay and stretch the video [03:48] <kode54> stretch is needed for youtube aspect handling after turning on 3D side by side mode [05:07] <misslesbian> Hello [05:25] <epsilon> what can be the reason, if ffmpeg is ignoring -acodec and -vcodec for output format? [05:26] <epsilon> trying to grab video, but it's taking mpg4 video and mp2 audio whatever I say [05:29] <relaxed> epsilon: pastebin.com [05:32] <epsilon> http://paste.debian.net/152112 - I tell to use v/acodec, but in lines 27/28 they are ignored [05:35] <drv> you need to put the output options after the input options [05:35] <drv> move -acodec xyz and -vcodec xyz after /dev/video0 [05:37] <epsilon> ah better [05:45] <epsilon> I was fooled cause -vcodec copy worked at the "wrong" position [05:51] <relaxed> epsilon: Your output will be huge. [05:52] <relaxed> -sameq does nothing in that command [05:53] <epsilon> ok, it's leftover from earlier test, cause -vcdiec was ignored [05:53] <relaxed> In fact if Zeus came down from heaven and made me king of the world, my first course of action would be to remove -sameq forever [05:54] <relaxed> then world peace [06:02] <epsilon> question is the bitrate... what should I take to encode analog PAL (720x480) into mpeg4, like ~8MBits as -sameq used? [06:04] <relaxed> If you just want great quality I recommend -qscale 3. [06:05] <Ginks> what would you recommend for a watermark overlay? [06:05] <Ginks> -qscale or qmax? [06:05] <relaxed> the qscale range is 1 (highest quality) - (lowest) 31 [06:05] <Ginks> I'm not even sure what qscale is [06:06] <Ginks> vs qmax [06:06] <Ginks> I'm not doing any scaling though [06:06] <Ginks> lol [06:06] <epsilon> qscale applies to VBR? I prefer CBR... [06:07] <Ginks> cbr is actually what I think I should be doing since it's streaming [06:07] <epsilon> I want to cut the grabbed video later with other tools, CBR vid and audio is better for that in my experience [06:07] <epsilon> VBR often resulted in async audio [06:07] <relaxed> keep it lossless if you're going to be editing [06:08] <epsilon> I'l keep PCM for audio, but video I'd like to use mpeg4 due to size [06:11] <relaxed> vbr should not affect sync in any way. [06:42] <epsilon> zomg [06:43] <epsilon> I wonder why I can't open libxvid encoded video in virtualdub in Windows -> I have to open hex editor and change manually "xvid" in the avi file to "XVID" [06:47] <relaxed> ffmpeg has -vtag [08:28] <burek> is there any ffmpeg based subtitle editor? [08:28] <burek> or any subs editor that supports h264 [08:34] <cbreak-work> h264 does not support subtitles [08:56] <jck_true_> burek: I think you're confusing with mp4 [08:57] <jck_true_> burek: Might wanna look at mp4box - http://gpac.wp.institut-telecom.fr/ [09:01] <cbreak-work> hmm... ffmpeg compiles fine on OS X, but somehow it fails to link on Ubuntu :( [09:02] <burek> no, i have subtitleeditor which doesnt want to load h264 movie [09:02] <burek> so im asking is there any other subtitle editor [09:02] <burek> which can load h264 movie [09:02] <burek> so i can edit my subtitles [09:03] <jck_true_> burek: Extract them with mp4box [09:03] <burek> and? [09:03] <cbreak-work> h264 doesn't support subtitles [09:03] <burek> :) [09:03] <burek> ok you are seriously misunderstanding something [09:03] <cbreak-work> if you have a movie that has subtitles, then it's most likely some container format that does [09:03] <burek> i have my subtitles [09:03] <burek> and a movie downloaded from the internet [09:04] <burek> i need a movie as a ref. point to sync subs [09:04] <burek> thats all [09:04] <jck_true_> oh [09:04] <jck_true_> no clue [09:04] <jck_true_> sorry [09:04] <burek> i dont need to embed/extract subs from a container :) [09:22] <burek> i solved it by installing gstreamer0.10-ffmpeg package :) thanks to all for help :) [09:25] <cbreak-work> I switched back from git master tip to n0.9.1 [09:26] <cbreak-work> but ffmpeg still doesn't compile on linux [09:26] <cbreak-work> http://paste.the-color-black.net/224216 [09:26] <cbreak-work> well, linker error that is, not a compiler error [09:31] <cbreak-work> well... seems all .o files are ... 0 bytes [09:53] <cbreak-work> well, finally managed to compile ffmpeg, but now it doesn't link: [09:53] <cbreak-work> http://paste.the-color-black.net/224219 [09:54] <cbreak-work> the same code does link on OS X [12:24] <cjhmdm> hello, can the latest source for ffmpeg & x264 still be found at git://git.videolan.org/x264 & git://source.ffmpeg.org/ffmpeg ? [12:25] <sacarasc> http://ffmpeg.org/download.html has the address for ffmpeg. http://www.videolan.org/developers/x264.html for x264. [12:28] <JEEB> cjhmdm, yes -- the repository address for x264 hasn't changed for ages [12:28] <JEEB> can be seen in the gitweb, too @ http://git.videolan.org/gitweb.cgi?p=x264.git [12:29] <cjhmdm> JEEB: thanks [13:08] <elkng> the smartphone supports natively "MP3/WMA/eAAC+" and "MP4/H.263/H.264", how can I convert video to supported format ? [13:08] <elkng> this: "ffmpeg -i 1.flv -vcodec h263 -vb 2000k -s 320x240 -ab 128k -ar 44100 -ac 2 -acodec libmp3lame -y -f avi 1.avi" cant be played [13:08] <elkng> and this: "mencoder 1.flv -o 2.avi -oac mp3lame -ovc xvid -xvidencopts bitrate=687" cant be played [13:17] <dipanjan> hi, can someone please explain to me the syntax of padding using -vf? [13:17] <dipanjan> -vf pad=width:height:x:y:color [13:31] <cjhmdm> hello, if I'm setting the following options - -b:v 1200k -minrate 1200k -maxrate 1200k - what would the proper -bufsize be? [13:32] <cjhmdm> or does it really matter? I'm not sure what this setting does exactly, so not sure how important it is [13:43] <burek> does anyone have a working example of burning subtitles onto a video? :) [13:43] <burek> using ffmpeg :) [13:46] <ubitux> -vf ass=foobar.ass [13:47] <burek> thx :) and how to convert txt/srt to ass? :) [13:49] <ubitux> gaupol/subtitleseditor/aegisub ? [13:49] <ubitux> maybe ffmpeg is able to do it btw [13:49] <ubitux> maybe try ffmpeg -i foobar.ass foobar.srt (not sure it will work) [13:49] <burek> subtitleeditor [13:50] <burek> heh save as :) thanks :D [13:52] <shroomM> anyone has any experience with ms's adaptive streaming solution - smooth streaming ? [13:56] <burek> ms? :S [13:56] <shroomM> microsoft ;) [13:57] <burek> yeah, i was afraid you're gonna say that :/ [13:58] <shroomM> haha, lol [13:58] <burek> :) [14:04] <ideea> hi :) can any1 help me: i have source video in WMV format, but when i try to convert it, to, for example, flv with this command: http://pastie.org/3178088 i get this error: http://pix.am/bUbG/ [14:08] <ideea> friends, help :D [14:13] <JEEB> first of all... [14:13] <JEEB> lol old ffmpeg .-. [14:13] <ideea> dunno, all from sid's rep [14:14] <JEEB> also, damn at that libx264 stuff... [14:14] <ideea> simplt apt-get :) [14:14] <JEEB> just build current libx264 and ffmpeg and apt-get the faac devel/lib package if you need that >_> [14:14] <ubitux> at least 3 years old [14:14] <JEEB> oh, and you probably need current yasm for x264 so build that first, too [14:15] <ideea> on other server: freebsd i have 0.8.5.git-9719f25 version [14:15] <ideea> but there another error [14:16] <ideea> http://pix.am/bNih/ [14:17] <ideea> input/output error with thw same command. [14:17] <ideea> :( [14:18] <ideea> well, here is full configured server for my task, but i can't get this convertation to work [14:18] <JEEB> > gcc from 2007 [14:18] <JEEB> anyways [14:18] <JEEB> minimize the command line [14:19] <JEEB> also jesus fuck that configure line .-. [14:19] <ideea> its important parameters for ffmpeg :) [14:19] <ideea> that i need. [14:19] <JEEB> ffmpeg -i input.wmv -vcodec libx264 -crf 20 -an out.flv [14:19] <JEEB> try this first [14:20] <ideea> same error [14:20] <JEEB> then it's borked [14:20] <JEEB> easy as that [14:20] <JEEB> either the compile or the input file [14:20] <JEEB> I'm going to bet on the compile first [14:20] <ideea> maybe, there is some problem with wmv? cause i can convert flv to mpg, for example [14:22] <JEEB> anyways, what gcc does the linux box have? [14:22] <JEEB> (don't tell me it's older than that freebsd's 4.2) [14:22] <ideea> 4.2.1 [14:22] <JEEB> .-. [14:22] <JEEB> ok, I don't want to have anything to do with you, sorry [14:22] <ideea> rofl :D [14:23] <ideea> any1 other?:)) [14:23] <ideea> or, tell me what to write to admins, they will configure server for it [14:23] <JEEB> in any case, build on some relatively sane set-up current yasm, current libx264 and ffmpeg with the minimal configure line (./configure --enable-gpl --enable-nonfree --enable-libx264 --enable-libfaac or so) [14:23] <JEEB> and check if it still fails [14:26] <ideea> ok, ty, i will tell support team of content srver to do this. [14:26] <JEEB> also, make sure that the wmv has no drm on it :V [14:27] <ideea> drm? [14:28] <JEEB> "digital rights management" [14:28] <JEEB> encrypted files in other words [14:28] <JEEB> which will naturally fail [14:28] <ideea> no, nothing with this. all videos are mine. [14:28] <ideea> well, its for porno studio.. :) [14:29] <JEEB> it seems like you just don't understand what I'm talking about at all .-. [14:30] <JEEB> in any case, do what I said and try with current libx264 and ffmpeg [14:30] <ideea> yes, i already wrote support team to do this, then i will try. [14:30] <ideea> thank you. [14:32] <JEEB> also, does this wmv file work? http://www.mediafire.com/?jllmmt3jtwh [14:33] <JEEB> with something simple like ffmpeg -i input.wmv -vcodec libx264 -crf 20 -an out.flv [14:49] <burek> I'm gonna build a generic big fat ffmpeg [14:49] <burek> and let people download and use it [14:49] <burek> (without non-free stuff) [14:49] <burek> even better, i'll make a cron job to rebuild it every 7 days [14:50] <burek> so they will have the latest binary all the time [14:59] <Mavrik> for which OS? :) [15:13] <ideea> JEEB, no. Also, with last ffmpeg, lib..etc same error. [15:46] <arbn> On one particular Linux box, ffmpeg produces an empty mp3 when piped some webm video input. I have the verbose output:http://bpaste.net/show/21766/ [15:46] <arbn> Any ideas on why? I can provide more details. [15:58] <relaxed> arbn: Works here. Maybe your ffmpeg is too old. [15:59] <arbn> The thing is, it worked on another machine with the exact same ffmpeg package. [16:01] <burek> Mavrik, debian most probably :) [16:05] <relaxed> burek: I have big fat staic builds people can download. https://sites.google.com/site/linuxencoding/builds [16:05] <relaxed> static* [16:05] <burek> great :) [16:06] <burek> we can make a list of OSes for download [16:06] <burek> to save time for others [16:06] <burek> i mean builds for different OSes :) [16:07] <arbn> OK. Saving the data to the command-line works. It's only when I try to convert through a pipe that it produces empty output. [16:10] <relaxed> arbn: you can cheat, ffmpeg -i input.webm -f nut - 2>/dev/null | ffmpeg -f nut -i - out.mp3 [16:11] <relaxed> actually, ffmpeg -i input.webm -vn -f nut - 2>/dev/null | ffmpeg -f nut -i - out.mp3 [16:17] <relaxed> arbn: er, that isn't lossless ^^, ffmpeg -i out.webm -vn -acodec pcm_s16le -f nut - 2>/dev/null | ffmpeg -f nut -i - -y out.mp3 [16:18] <relaxed> that's my final answer. [16:20] <arbn> relaxed: my input is coming via a pipe, not a file. [16:20] <arbn> It's raw piped video data. [16:20] <arbn> [nut @ 0x8712880]EOF before video frames [16:20] <arbn> pipe:: Operation not permitted [16:23] <relaxed> if it's raw yuv you need to tell ffmpeg how to decode it. ... | ffmpeg -s WxH -r framerate -pix_fmt yuv420p -f rawvideo -i - [16:25] <arbn> ffmpeg -loglevel quiet -i pipe:0 out.mp3 [16:26] <arbn> It works fine, expect on this one machine. Now raw video, but the WebM bytes. Sorry. [16:26] <arbn> Not raw* [16:28] <arbn> I am piping a WebM file byte-by-byte to stdin, and trying to encode into mp3. [16:28] <relaxed> I don't think that's going to work [16:28] <arbn> It does. On every machine I've tried it on, except this one. [16:32] <relaxed> my mistake, it does work. [16:34] <arbn> Yeah. Except that, in this one case, the mp3 output is empty. I wouldn't expect ffmpeg to stop reading the stream until EOF, though, so I don't understand at all. [16:38] <arbn> Oh. The ffmpeg output is different... [16:39] <arbn> Would the difference between "libmp3lame" and "mp3" be significant? [16:41] <relaxed> what's different? [16:42] <arbn> Stream #0.0: Audio: libmp3lame, 44100 Hz, stereo, s16, 64 kb/s [16:42] <arbn> Under "metadata:" [16:42] <arbn> The other machine has "mp3" there. [16:44] <relaxed> Are you sure they're using the same packages? I think "mp3" is the old name for "libmp3lame" [16:45] <arbn> Oh. No, these aren't the same packages. I'll try it on the machines that have the same packages, and then paste the output for both on bpaste. [16:55] <arbn> http://bpaste.net/show/21774/ [16:55] <arbn> There. As you can see, the top output concludes with 0kb audio. [16:56] <arbn> The command is the same. [16:57] <relaxed> the solution would seem to be updating the other machines ffmpeg version [16:59] <relaxed> it looks like 0.6.3 predates webm [17:00] <arbn> Oh. Wow. No idea how I missed that. I need to sleep. Thanks for your help and patience. [17:01] <relaxed> you're welcome [17:07] <NapHtaKeRoSene> hi [17:07] <NapHtaKeRoSene> i have invented area map in 8 hours, good time? [18:16] <naeluh> Hi all having trouble installing yasm can anyone give me a hand I am on ubuntu [18:22] <grepper> naeluh: if apt-get install yasm is failing you probably need help in #ubuntu [18:22] <naeluh> grepper:okay cool [18:56] <Budd> I'd like to decode video frames into RGB, but with layout of row > channel > column (in decreasing order of significance) [18:57] <Budd> All the RGB formats I see listed put the three channels for one pixel together. [18:57] <Budd> Is there a way to specify my own format for libavformat to use, or should I just suck it up and reorder the data myself? [19:10] <teratorn> Budd: you mean planar rgb? [19:10] <Budd> teratorn: not quite, but that would be better. [19:11] <teratorn> see the GBRP* formats then, I guess [19:13] <Budd> My layout goal is to have all the red values for one row contiguous, then group three of those to make one line. [19:14] <Budd> I think my error was grepping for RGB, not GBR - thanks! [19:15] <Budd> nope - not seeing GBRP in libavutil/pixfmt.h [19:17] <Budd> I suppose learning to to the SSE shuffle will let me reorder pixels fast enough. [19:17] <Budd> I may write a tune called the "SSE shuffle" [19:19] <fris> trying to compile 0.9.1 and keep getting this error http://pastie.org/3179640 any ideas? [19:40] <naeluh> hi is there documentation on installing libfaac? thanks!! [20:03] <naeluh> cant install libfaac can some one help [20:29] <arbn> naeluh: Give more detail than "can't install". What's happening? [20:30] <naeluh> arbn: thanks [20:31] <naeluh> arbn: I am on ubuntu lucid I used command sudo apt-get install faac should that be suffcient? [20:31] <naeluh> it looked like it worked [20:32] <relaxed> you will need the -dev package too [20:32] <arbn> If you're compiling ffmpeg, you want libfaac-dev, yeah. [20:32] <naeluh> like this sudo apt-get install libfaac-dev libfaac0 [20:32] <arbn> I think so. I don't use Ubuntu or Debian. [20:33] <naeluh> I did that and it looks like it worked [20:43] <naeluh> weird it still isnt wrking [20:43] <naeluh> is there a way to find out if libfaac is installed ? [20:44] <relaxed> are you running ./configure --enable-libfaac --enable-nonfree ? [20:49] <naeluh> would I run that when I configure ffmpeg [20:49] <relaxed> yes [20:55] <naeluh> I think it might be a problem with an install script I am using its this one http://www.ffmpeginstaller.com/ [20:55] <naeluh> I think maybe I should try to compile it myself [20:55] <naeluh> cause it seems to be screwing up [21:18] <JEEB> [mp4 @ 0x1da33c0] malformated aac bitstream, use -absf aac_adtstoasc -> [aac @ 0xc13700] Multiple RDBs per frame with CRC is not implemented. [21:18] <JEEB> normal behavior? [21:19] <JEEB> (mp4 output with ffaac) [21:19] <JEEB> (yes, the person I'm helping doesn't have any other aac encoders installed) [21:26] <relaxed> you're stream copying aac to mp4 [21:27] <relaxed> ? [21:27] <JEEB> nope [21:27] <JEEB> -acodec aac [21:27] <JEEB> (with strict experimental) [21:27] <relaxed> that shouldn't happen [21:28] <JEEB> ...yeah [21:28] <relaxed> then your answer is no :) [21:30] <JEEB> http://pastie.org/3180336 -> http://pastie.org/3180342 [21:30] <JEEB> some arch packaged ffmpeg [21:30] <JEEB> ffmpeg -i input.derp -s 480x272 -vcodec libx264 -crf 22 -preset fast -profile main -level 3 -x264opts ref=3:b-pyramid=none:weightp=1 -acodec aac -strict experimental -ab 192k -absf aac_adtstoasc out.mp4 [21:30] <JEEB> s/profile/profile:v/ [21:30] <JEEB> should be the command line [21:31] <JEEB> he can't paste it all because he seemingly is using his distro without a DE... and not through ssh .-. [21:32] <ioni> maybe ffmpeg master requires a more newer x264? [21:33] <JEEB> I don't see libx264 being the problem >_> [21:33] <Milos_SD> Hello... I have a little problem with gstreamer-ffmpeg in Ubuntu 11.10 ... I have ffmpeg compiled from source from git. Today I compiled a new version of ffmpeg from latest git, and Totem and mozilla-totem can't play any videos. When I do "gst-inspect" I get this on the begining: http://pastebin.com/d698m1hT How can I solve this? [21:33] <ioni> that is a 2 days old snapshot [21:34] <ioni> jeeB let me do another package [21:34] <JEEB> oh, you're the guy responsible for this? [21:34] <JEEB> lol [21:34] <ioni> yeah :) [21:34] <JEEB> also, add libvo_aacenc if you can... you're already at gplv3 anyways >_> [21:34] <ioni> no [21:34] <JEEB> aww [21:35] <ioni> is not in the repos and i don't want to maintain yet another package [21:35] <JEEB> oh well, for a mobile device ffaac should be good enough [21:35] <JEEB> if it would work .-. [21:35] <JEEB> anyways, a newer libx264 isn't a bad idea, but I just don't see why an older libx264 would be the problem here >_> [21:36] <JEEB> libx264 seems to be working fine, but the audio part seems to herp a derp [21:36] <ioni> i don't have time now to recompile all packages for new x264 [21:36] <JEEB> well, as I said I don't really think that error happens because of libx264 >_> [21:37] <JEEB> at least it doesn't show itself anywhere [21:37] <ioni> Milos_SD, gstreamer-ffmpeg doesn't use external ffmpeg [21:37] <ioni> at least developers do not suggest using it [21:38] <Milos_SD> ioni, so why does it segfault when I have ffmpeg from source, and not when I have ffmpeg from ubuntu repo? [21:38] <ioni> JEEB i686 or x86_64? [21:38] <ioni> Milos_SD, no idea, get a trace [21:38] <JEEB> ioni, no idea -- I'll ask the guy >_> [21:39] <ioni> cool [21:41] <ioni> jeeB http://pkgbuild.com/~ioni/ffmpeg/ [21:41] <JEEB> linked to the guy [21:41] <Milos_SD> ioni, this: http://paste.ubuntu.com/803410/ ? [21:41] <ioni> Milos_SD, no [21:41] <ioni> gdb trace [21:46] <Milos_SD> ioni, never mind, fixed it by compiling gstreamer-ffmpeg :D [21:46] <ioni> jeeb any news? [21:46] <JEEB> ioni, seems to do the same thing [21:46] <ioni> ok [21:47] <ioni> let me compile new x264+ffmpeg rebuild [21:50] <relaxed> JEEB: If the preson you're helping is using 64bit linux: https://sites.google.com/site/linuxencoding/builds [21:51] <ioni> relaxed, because using some random binary from internet helps a lot ?:) [21:51] <ioni> while keeping the distro version broken [21:53] <JEEB> relaxed, thanks but I have no idea about which arch he is even now. He never answered that question, just tried ioni's newer compile [21:53] <JEEB> I actually asked the guy for ssh access to his box so I could handle compilation of multimedia stuff etc. for him... but it seems like he hasn't even installed openssh yet .-. [21:54] <JEEB> no idea how the hell he's using arch without a DE and without using it externally via ssh [21:54] <relaxed> ioni: I have no control over distro's broken ffmpeg packages and all the control over my own. [21:55] <ioni> the point is that is better to fix the bug upstream rather that workaround the issue by using some random stuff [21:55] <ioni> jeeB tell him to install the new packages [21:55] <ioni> x264 and ffmpeg [22:06] <ioni> jeeB don't forget to pacman -Suu after [22:06] <ioni> x264 had a soname bump [22:07] <JEEB> posted that to the guy... kind of herping a derp because I can't get access to the box so I can't exactly see what the heck he's doing .-. [22:51] <ioni> jeeB any luck? [23:21] <ValW> @find *air*supply* [23:43] <gentt> Hello guys [23:43] <gentt> I need some help with the commands [23:44] <gentt> 'man' didn't help much [23:44] <llrcombs> what are you having trouble with? [23:44] <gentt> so i have video .mp4 which is in 1080p [23:44] <gentt> i want to convert it into .avi with 480p [23:44] <gentt> what command should i use? [23:45] <gentt> llrcombs, ? [23:46] <llrcombs> ffmpeg -i original.mp4 -acodec nameYourCodec -vcodec nameYourCodec -s 854x480 out.avi [23:46] <llrcombs> throw in an -acodec and bitrate settings [23:46] <llrcombs> (right now that command is incomplete) [23:46] <llrcombs> or make it 720x480 if you want DVD quality [23:47] <llrcombs> here, have a cheat sheet: http://rodrigopolo.com/ffmpeg/cheats.html [23:55] <gentt> llrcombs, what nameYourCodec would be? [23:57] <gentt> in the end i just used ffmpeg -i original.mp4 -sameq -s 854x480 out.flv [23:59] <JEEB> > sameq [23:59] <llrcombs> well, if you want an FLV, that works [23:59] <JEEB> sameq does not do what you think it does [23:59] <JEEB> the new ffmpeg help should properly say what it does [23:59] <llrcombs> JEEB: I've been wondering, what exactly does it do? [23:59] <llrcombs> (assuming I'm using latest git [I am]) [23:59] <JEEB> it has always done the same thing. it copies the qp values from source and uses them as-is. [00:00] --- Sat Jan 14 2012

[02:04] <OanaStra_> ubitux: yes [02:06] <ubitux> first, fix your indent [02:06] <ubitux> next, change ff_vorbis_floor1_render_list prototype to make it return an int [02:06] <ubitux> so you can return -1 in this function too if render_line fails (aka raise the error at a upper level) [02:07] <ubitux> then in the decoder (vorbisdec), check the return value of ff_vorbis_floor1_render_list [02:07] <ubitux> and return AVERROR_INVALIDDATA in case of a negative value [02:08] <OanaStra_> the prototype meaning making it int ff_vorbis_floor1_render_list no? [02:13] <OanaStra_> ubitux: http://pastebin.com/JNKNbeqP my diff [02:14] <ubitux> yes something like this, but you need to change the prototype in the header file [02:14] <ubitux> and your patch is not done [02:14] <OanaStra_> done that too [02:15] <ubitux> then your diff is incomplete [02:16] <OanaStra_> http://pastebin.com/cxGWT10M [02:16] <OanaStra_> this is the full one [02:18] <OanaStra_> ubitux: any comments on it? [02:19] <ubitux> overall looks good if it works but: [02:19] <ubitux> line 25: indent is wrong [02:19] <ubitux> nit: i'd add a comment such as: if (!adx) // avoid FPE [02:19] <ubitux> you can merge the two if [02:19] <ubitux> if (lx < samples && [02:19] <ubitux> render_... [02:20] <OanaStra_> ok [02:20] <ubitux> also, it is common to use if (foobar() < 0) instead of exact -1 [02:20] <ubitux> (it allows to return different kind of error for instance) [02:20] <ubitux> line 75: indent is wrong [02:21] <OanaStra_> done all of those [02:22] <ubitux> if you fix these, git commit with a proper message ("vorbis: fix FPE [...]") I think you can submit it to ffmpeg-devel [02:22] <ubitux> (with git send-email -1 for instance) [02:22] <ubitux> did you ever use git send-email btw? [02:22] <OanaStra_> no [02:22] <OanaStra_> i must set it up [02:22] <ubitux> wanna try? [02:22] <OanaStra_> yes [02:23] <ubitux> do you have a gmail or you're using another smtp? [02:23] <OanaStra_> gmail [02:23] <ubitux> then: http://pastie.org/3169740 [02:23] <OanaStra_> 1st please look at my diff once again http://pastebin.com/LzZuR7gb [02:23] <ubitux> add sth like that in your ~/.gitconfig [02:23] <OanaStra_> if it is good [02:24] <ubitux> you still have a == -1 [02:24] <ubitux> multiple ones actually [02:24] <ubitux> you forgot to merge the if () line 48 [02:24] <ubitux> and you can keep the line break [02:24] <ubitux> if (lx < samples && [02:24] <ubitux> render_line... < 0) [02:24] <ubitux> return -1 [02:25] <ubitux> while you are at it, you can fix the broken vertical align after changing the void into int (see the parameters columns) [02:26] <OanaStra_> put how many spaces in front of it? [02:26] <ubitux> just remove one space each line [02:27] <ubitux> "vorbis_floor1_entry * list" must be vertically aligned with "uint16_t *y_list..." and "int multiplier..." [02:27] <ubitux> do you see what i mean? [02:27] <ubitux> (you need to change it in both the .c and .h) [02:27] <OanaStra_> yes [02:28] <ubitux> sorry for all these nits [02:28] <ubitux> :) [02:28] <OanaStra_> no no , i`m glad i can help [02:28] <OanaStra_> http://pastebin.com/M2UW2N9f [02:28] <OanaStra_> this is the last one [02:28] <OanaStra_> latest* [02:29] <ubitux> "< 0" is preferred to "<0" [02:30] <ubitux> also, indent is broken line 54 (are you indenting by hand?) [02:30] <ubitux> you didn't break the line either when merging the if (we try to avoid very long line) [02:31] <OanaStra_> using TextMate and when i hit enter it thinks it`s tab and puts me beneath the previous line [02:31] <OanaStra_> how can i break it as to be good ? [02:31] <ubitux> i showed you two times :) [02:32] <ubitux> read the logs :p [02:32] <OanaStra_> oh yes [02:32] <OanaStra_> i`m a bit zzz [02:32] <OanaStra_> ok done all of those [02:32] <OanaStra_> so know mail it ? or you wanna take a look at the final version? [02:33] <ubitux> 02:23:29 <@ubitux> then: http://pastie.org/3169740 [02:33] <ubitux> 02:23:37 <@ubitux> add sth like that in your ~/.gitconfig [02:33] <ubitux> for the mail [02:33] <ubitux> the do a proper git commit, and then git send-email -1 (to send the last commit) [02:33] <ubitux> and you send it to ffmpeg-devel(a)ffmpeg.org [02:34] <ubitux> if you are not subscribed to the mailing list, you will need to wait for moderation [02:34] <OanaStra_> i am subscribed [02:35] <OanaStra_> but where do i put the pass for the gmail account? [02:35] <OanaStra_> it will be required when i git send-emal ? [02:35] <OanaStra_> email* [02:35] <OanaStra_> requested not required [02:36] <ubitux> you will be prompted a few questions [02:36] <OanaStra_> ko [02:36] <OanaStra_> ok [02:37] <OanaStra_> ubitux: vorbis: fix FPE when multiple values of x in the floor1 list [02:37] <OanaStra_> ubitux: good commit message ? [02:38] <ubitux> sounds good yes [02:40] <OanaStra_> ubitux: Message-ID to be used as In-Reply-To for the first email? what should i say here? [02:42] <ubitux> leave it blank [02:43] <OanaStra_> ubitux: http://pastebin.com/VGA0tTat any idea? [02:44] <ubitux> ah yeah you need a few perl mail related packages to use it [02:44] <OanaStra_> know the name of them?

[04:29] <michaelni> ill CC you when i post it to the ML [04:29] <OanaStratulat> thx [04:29] <michaelni> your patch is ok, it just can be done a bit simpler [04:30] <OanaStratulat> posting to ML now or i`ll go to zz ? [04:33] <michaelni> i need to run some tests first to make sure it works and breaks nothing [04:33] <michaelni> then ill post [04:34] <OanaStratulat> ok [04:34] <OanaStratulat> awaiting for it [04:34] <OanaStratulat> until then good night [04:35] <michaelni> OanaStratulat, mail sent [04:35] <OanaStratulat> michaelni: thx [04:36] <OanaStratulat> gn [04:36] <michaelni> gn [04:46] <michaelni> ubitux, btw, thx for mentoring Oana!

[23:43] <ubitux> only audio afaik [23:43] <gnafu> Not open source, but Adobe Connect works well across Windows, Mac, and Linux. [23:43] <ubitux> same for mumble (not sure it's the name) [23:43] <Compn> heh videochat [23:44] <gnafu> Each participant can send and receive video and audio, and presenters can share application windows or desktops, and there is a whiteboard feature and such. [23:44] <ubitux> it's free? [23:44] <gnafu> No :-(. [23:44] <gnafu> But for what it costs, I find it to be very nice. [23:44] <Compn> theres gotomeeting [23:44] <Compn> but thats not free [23:44] <Compn> and a hack for linux support [23:45] <Compn> oh there was 'dimdim' [23:46] <Compn> but its not open source anymore [23:46] <Compn> ubitux : http://www.bigbluebutton.org/ [23:46] <Compn> there [23:46] <gnafu> I'm hoping WebRTC makes some of these kinds of things easier to do freely in the browser. [23:47] <Compn> BigBlueButton is an open source web conferencing system built on over fourteen open source components to create an integrated solution that runs on mac, unix, or PC computers. In the true sense of open source, we invite you to try out and participate in our project. [23:47] <ubitux> let me check :) [23:47] <ubitux> thx [23:49] <ubitux> mpf. !@$ flash; i still can't click on the accept/cancel security check& [23:49] <ubitux> it's been years i have this issue, and not a single flash update solved it [23:51] <Compn> what flash security check ? [23:51] Action: Compn never seen one [23:51] <Compn> use an updated browser [23:52] <ubitux> if you want to share the webcam, you need to allow flash to access it [23:52] <ubitux> and thus there is a popup [23:52] <Compn> oh [23:52] <ubitux> michaelni: yes i'm not able to get them either [23:52] <ubitux> i guess that's not yet supported [23:53] <gnafu> Hmm, I've not had problem clicking the button to allow. [23:53] <gnafu> s/had problem/had a problem/ [23:53] <gnafu> ubitux: Do you have nspluginwrapper installed? [23:54] <gnafu> I wonder if that's interfering. [23:55] <ubitux> no [23:55] <Compn> what web browser / version ? [23:56] <ubitux> i tried with firefox9 and chromium 16 [23:56] <ubitux> but i have this issue since firefox3 (when i actually noticed it, but it might already existed for long) [23:57] <gnafu> What OS do you use? [23:58] <ubitux> archlinux, 64bits [23:58] <ubitux> but i was able to reproduce the exact same issue using an ubuntu vm [23:58] <Compn> 64bits :) [23:59] Action: gnafu uses Fedora 64-bit with 64-bit Flash in Firefox 9 without issue. [23:59] <ubitux> (i reported the issue but they didn't seem to be able to reproduce it) [23:59] <gnafu> It is odd that it doesn't happen in other distros. [23:59] <ubitux> it happens in ubuntu with my tests [23:59] <gnafu> Strange. [23:59] <ubitux> but well i must be cursed [23:59] <gnafu> I wonder what Fedora does differently. [23:59] <ubitux> or totally stupid [00:00] --- Fri Jan 13 2012

[00:38] <darkstarbyte> anyone know a lot about multithreading in ffmpeg? [01:01] <Ginks> threads=0 or threads=auto I think [01:12] <darkstarbyte> I was wondering how effective threads were on the mpeg2 codec [02:00] <iive> darkstarbyte: not that much. I remember that things like reading from the same bitstream were memory hogs [02:00] <iive> so even the bitstream should be copied for each thread. [02:01] <naeluh> hey is there a way to install libfacc on ubuntu lucid ? [02:02] <iive> naeluh: do you mean libfaac ? [02:02] <naeluh> live: yes [02:04] <naeluh> live: 1 sec I think it ma9y have installed [02:21] <naeluh> hey so I am getting ERROR: libfaac not found [02:21] <naeluh> live: is there a way to install it [02:24] <shevy> naeluh http://downloads.sourceforge.net/faac/faac-1.28.tar.bz2 [02:24] <naeluh> awesome thanks let me try it ! [02:30] <naeluh> awesome worked how about libmp3lame [02:32] <iive> you can download it from sf.net too [02:34] <naeluh> awesome [02:34] <naeluh> hows everyone doin today [02:35] <naeluh> weird now it says I dont have libopencore_amrnb [02:37] <naeluh> is there a place to download that [02:37] <shevy> hmm that's an odd lib [02:37] <naeluh> maybe I dont need it [02:37] <shevy> I know libfaac, I know liblame but I never heard of that libopencore* before [02:37] <naeluh> I will try with enablbing it [02:37] <naeluh> enable [02:38] <shevy> I think I found it... let me dig https://trac.pjsip.org/repos/changeset/3911/pjproject/trunk/pjmedia/src/pjm… [02:38] <shevy> it belongs to that project probably [02:38] <shevy> http://www.pjsip.org/release/1.12/pjproject-1.12.tar.bz2 seems to be the stable one [02:39] <naeluh> awesome! [02:39] <naeluh> how bout libtheora [02:39] <naeluh> is there one out there [02:39] <naeluh> thanks again [02:40] <shevy> libtheora is easy [02:40] <shevy> works for me very well http://downloads.xiph.org/releases/theora/libtheora-1.2.0alpha1.tar.xz [02:40] <shevy> or look for another version http://downloads.xiph.org/releases/theora/?C=M;O=D but the above should be the latest [02:41] <naeluh> shevy: u r gr8 [02:41] <shevy> I have those things in local files [02:42] <shevy> "compile libtheora" in bash compiles it for me. if it can not find it locally, it will download it and put it into SOURCE_DIRECTORY/name_of_program ... like /Depot/libtheora/ [02:42] <naeluh> cool thanks !! [02:49] <naeluh> is there a way to untar a file like libogg-1.3.0.tar.xz [02:50] <shevy> yes [02:50] <shevy> the binary (or script is called) [02:50] <shevy> "unxz" [02:50] <shevy> it is bundled there http://tukaani.org/xz/xz-5.0.3.tar.bz2 [02:50] <shevy> .xz files usually have smaller size than .bz2, that's why they are used [02:51] <shevy> you can however also download other formats naeluh like http://downloads.xiph.org/releases/ogg/libogg-1.3.0.tar.gz [02:54] <naeluh> weird when I run ./configure --prefix=/usr && it wont configure ? [02:54] <naeluh> \ [02:55] <naeluh> ls [02:55] <naeluh> wrong diretory [02:55] <naeluh> directory [02:59] <shevy> hmm [02:59] <shevy> you should not use the && I think [02:59] <shevy> "./configure --prefix=/usr" should be enough [02:59] <shevy> my alias to this is "cusr" [02:59] <shevy> :) [03:00] <shevy> or rather "doit"... as alias being ./configure --prefix=/usr, then make, then make install [03:06] <naeluh> I got it I was in the wrong directory [03:08] <darkstarbyte> Unrecognized option 'acodec' [03:08] <darkstarbyte> Is ffmpeg broken on my computer? [03:09] <durandal_1707> full cmd output [03:10] <darkstarbyte> http://pastebin.com/QfEdu8ZR [03:11] <relaxed> ffmpeg, not ffprobe [03:11] <darkstarbyte> crap [03:11] <darkstarbyte> a typo [03:11] <relaxed> -profile:v high [03:12] <darkstarbyte> oh [03:14] <darkstarbyte> that explains that error [03:14] <naeluh> I got it wrkin thanks [03:15] <shevy> cool naeluh [03:16] <naeluh> yeah its al configured but that one libopencore ? it still couldnt find it after I installed that one link [03:17] <naeluh> shevy I am going to try it without and see how it goes [03:24] <naeluh> shevy can you show me how to determine the Absolute path to ffmpeg executable? [03:25] <naeluh> thanks again [03:25] <newl> which [03:25] <newl> which ffmpeg [03:25] <naeluh> I installed using these instructions http://ubuntuforums.org/showpost.php?p=9868359&postcount=1289 [03:26] <naeluh> I guess the latest one [03:26] <naeluh> newl does that make sense [03:26] <newl> is your 'i guess the latest one' the answer to 'which ffmpeg' (god i love that one ...) no just type it in a terminal [03:27] <naeluh> newl your a funny guy [03:28] <naeluh> I found it thanks !! [03:30] <naeluh> weird I used the which ffmpeg command it showed me a directory /usr/local/bin/ffmpeg then I tried to cd to it and it said that it didnt exist? [03:30] <shevy> well [03:30] <shevy> something is odd [03:31] <naeluh> yeah [03:31] <shevy> if you used --prefix=/usr then ffmpeg would be at /usr/bin/ffmpeg [03:31] <shevy> also, that is a binary, not a directory, so you can't cd to a file [03:31] <naeluh> oh okay [03:31] <shevy> you can give the absolute path though and look what it outputs ./usr/local/bin/ffmpeg [03:31] <shevy> hmm or without the . [03:33] <naeluh> I am using a drupal installation which is asking for the path to ffmpeg executable I am trying to find it but no luck [03:33] <newl> naeluh: which shows you the full path to the binary (man which) [03:34] <naeluh> weird thats what I used and it is not recognizing it [03:34] <shevy> drupal [03:34] <shevy> isn't that some webserver thingy [03:34] <naeluh> shevy drupal.org [03:34] <naeluh> its a cms [03:34] <shevy> perhaps it can not see your /usr/local/dir [03:34] <shevy> because you have a base dir somewhere else [03:35] <naeluh> I think it can [03:35] <newl> try /usr/local/bin maybe it just wants the dir it is in - anyway drupal should be using your system path to find stuff ?? I would hope [03:35] <naeluh> can I create a sym link or somethin [03:35] <shevy> naeluh hmm... my apache has a document root that is somewhere in /www/bla [03:35] <shevy> and from there, it cant see my /usr/bin things [03:36] <naeluh> maybe a symlink to the /www [03:36] <shevy> sure, symlink into your root dir [03:42] <naeluh> ln -s /usr/local/bin/ffmpeg /www/ffmpeg [03:43] <naeluh> I used this but doesnt seem to wrk [03:47] <newl> you need the symlink directive in your httpd.conf for that dir? [03:49] <naeluh> I ran a check install on the ffmpeg folder and it output this [03:49] <naeluh> Done. The new package has been installed and saved to [03:49] <naeluh> /root/ffmpeg/ffmpeg_5:git-2012-01-11-4093d13-1_amd64.deb [03:49] <naeluh> You can remove it from your system anytime using: [03:49] <naeluh> dpkg -r ffmpeg [03:49] <naeluh> does that mean its in the root directory? [03:52] <newl> -> /root/ffmpeg more likely [03:55] <shevy> naeluh when you use dpkg by default it would install into /usr/bin [03:56] <shevy> if not, then tell the debian/ubuntu guys they are idiots [03:56] <naeluh> is there a way to test if ffmpeg is installed [03:56] <naeluh> or something [03:56] <shevy> if you use shell, just type "ffmpeg -v" [03:56] <naeluh> ffmpeg: error while loading shared libraries: libfaac.so.0: cannot open shared object file: No such file or directory [03:57] <shevy> libfaac.so.0 is not existing on your system [03:57] <shevy> also make sure to run "ldconfig" [03:57] <shevy> and try again [03:57] <shevy> /usr/lib/ls *faac* [03:57] <shevy> libfaac.a libfaac.la libfaac.so libfaac.so.0 libfaac.so.0.0.0 [03:57] <shevy> stat libfaac.so.0 [03:57] <shevy> File: `libfaac.so.0' -> `libfaac.so.0.0.0' [03:58] <shevy> I dont believe you naeluh [03:58] <shevy> I compiled libfaac into /usr and it works fine here for me. [03:58] <naeluh> wait shevy should I change that file [03:58] <shevy> depends on what you did before [03:58] <shevy> you probably did not compile libfaac into /usr prefix [04:00] <naeluh> so I would have to recompile libfaac and then recompile ffmpeg ? [04:05] <shevy> naeluh I dont think you compiled any of this either [04:05] <shevy> you used apparently a .deb package [04:05] <newl> what does ldd /usr/local/bin/ffmpeg | grep libfaac [04:05] <shevy> it's bad to mix things. debian/ubuntu wants its users to stick to its schemata [04:05] <naeluh> okay [04:06] <naeluh> hey I gotta go go am going to try again tomorrow and see if I can get it to work thanks for your help!!! [04:18] <newl> why would drupal use ffmpeg any way [10:27] <eightfold> is there a "plain" MPEG-4 ASP encoder, or is ASP only available as XviD, DivX etc? [10:28] <Tjoppen> -vcodec mpeg4 perhaps? [10:48] <upvar> how do i increase the contrast of my transcode slightly [13:14] <libin_v> Hi All, I would like to create an IPhone app which allows me to send CMSampleBuffer to an ffmpeg client over the network. Any pointers as to how I can achieve this? [13:17] <libin_v> After some amount of research .. I think I need to get the ImageBuffer from SampleBuffer. Put them into AVFrame and encode these frames using av_encode_video and then write them into a socket. .. am I right ?? [14:05] <chub_> anybody here knows about ffmpeg linking with quick sync's dlls and using quicksync for encoding/decoding? [14:27] <abli> Hi! what units is the 'time' in, which is printed on the command line when converting a video? I.e. there is a continously updating line like this: "size= 10826kB time=1316.57 bitrate= 67.4kbits/s". What units is the time part in? [14:42] <Mavrik> abli, seconds [14:43] <abli> ok, thanks [15:38] <gdp16> Hi [15:46] <gdp16> I have question [15:58] <Mavrik> good for you ;) [15:58] <gdp16> ^^ [15:59] <gdp16> currently I am building ffmpeg in cygwin environment [15:59] <gdp16> and it's configured using below configuration [16:00] <gdp16> --enable-cross-compile \ --cross-prefix=i686-pc-mingw32- \ --target-os=mingw32 \ --arch=x86 \ --sysroot=/usr/i686-pc-mingw32/sys-root/ \ --sysinclude=/usr/i686-pc-mingw32/sys-root/mingw/include/ \ --enable-static \ --disable-shared \ --enable-zlib \ --extra-cflags='-mno-cygwin -mms-bitfields' \ [16:00] <gdp16> when I run, ffmpeg [16:00] <gdp16> ffmpeg can't load libz-1.dll [16:00] <gdp16> does anyone have idea? [16:03] <JEEB> you built/have a dynamic zlib installed and that got linked [16:03] <JEEB> nothing more, nothing less [16:03] <JEEB> also, I think newer gccs don't work with -mno-cygwin so you must be using something old [16:03] <JEEB> but that's a separate problem :P [16:05] <gdp16> I use i686-pc-mingw32-gcc version 4.5.2 [16:06] <gdp16> and how to avoid this error? is there any special configuration to not use zlib shared library? [16:08] <JEEB> dunno, I just usually don't have the dynamic lib around .-. [16:09] <gdp16> @JEEB, did you also build ffmpeg in cygwin, if you did, would you let me know your configuration? [16:11] <JEEB> I use msys/mingw in most cases >_> [16:11] <gdp16> owh... [16:13] <Guest59107> hi guys, i'm trying make a image loop video with fade in and fade out. How can i make it to fade in & fade out from white ? [16:13] <Guest59107> here is my command [16:13] <Guest59107> http://pastebin.com/Ymn71cSj [16:40] <gdp16> @JEEB, i try to build in msys/mingw environment. [16:40] <gdp16> but I got warning, pkg-config not found.. [16:40] <gdp16> is that OK? [16:40] Action: JEEB sighs [16:41] <JEEB> if you don't understand that you could've just dealt with the dynamic lib of zlib and built a static lib I'm quite sure you're completely not sure what you're doing .-. [16:42] <gdp16> hmmm.. [16:43] <gdp16> I am newbie in here ^^.. [16:50] <Guest59107> if anyone could help me, i will send you a pint of beer :) [16:53] <Guest59107> oh well it was worth a try [16:53] <cbreak-work> hmm... ffmpeg headers fail to compile on linux [16:53] <cbreak-work> they worked fine on mac os [16:54] <cbreak-work> error: /usr/local/include/libavutil/common.h:170:47: error: UINT64_C was not declared in this scope [17:48] <dericed> maybe a dumb question: can I run latest git of ffmpeg with libx264 on Ubuntu 10.04. I have a project where I need both the latest ffmpeg and the LTS of Ubuntu [17:51] <gdp16> yes [17:51] <gdp16> I think you can use git command [17:51] <dericed> thanks [17:52] <thoro> Hello everyone - so, I'd like to decode a MPEG4-Video Stream from an ACTi Hardware Encoder (TCP Stream) and use the rendered frame in a .net Application - I already parse the tcp stream and filter out the raw MPEG4 data, I've initialized a AVIOContext with callbacks at read_packet and seek, but after the first 10 bytes i get 2 errors ( err{or,}_recognition separate: 193588380; 86261680, err{or,}_recognition combined: 193588380; 265008619) af [17:54] <thoro> I'm currently initializing the stream with av_open_input_stream and a pre selected AVInputFormat (m4v) [18:30] <thoro> okay got it working :) - used new instead of av_alloc_context [18:41] <thoro> how can I reduce the cached time? [18:44] <kriegerod> thoro: you can open your tcp socket as input, iirc [18:48] <pasteeater> dericed: of course http://ubuntuforums.org/showpost.php?p=9868359&postcount=1289 [18:51] <Arthur_D> once again, I'll ask if anyone knows how to improve the resulting audio when recording video with glc and audio with ffmpeg. If anyone knows how to make the resulting audio not stutter, I'd be very grateful [18:56] <pasteeater> Arthur_D: does the audio stutter when you do not record video at the same time? [18:57] <pasteeater> also, use a pastebin site to show your ffmpeg command and the complete console output [18:57] <thoro> kriegerod: but I need the data that's sent in the B2 headers and there's auth -- btw it already works :), just 800 ms delay - how do I minimize that? [18:58] <kriegerod> thoro: do you _decode_ packets using libavcodec also? if so, probably there're options that can be tuned to speedup [18:59] <kriegerod> for example, you can turn on decoding multithreading [18:59] <kriegerod> although its better to check all the system, possibly several places can be enhanced in terms of performance [19:00] <thoro> I don't think it's a performance problem [19:00] <Arthur_D> pasteeater: no, it does not stutter when I don't record video at the same time. I'll put up a pastebin ASAP [19:00] <thoro> it just just caches stuff like in vlc player where you can reduce the Caching [19:01] <thoro> okay, it definitly caches a certain amount of KB (just reduced the Bitrate and now the lagg is much higher) [19:01] <kriegerod> if you just give it data stream, and take back AVPacket's, it should not cache anything [19:01] <thoro> yeah I do that [19:05] <Arthur_D> pasteeater: http://pastebin.com/chERRADi [19:10] <pasteeater> Arthur_D: i do not believe MP3 is officially supported in MP4. [19:10] <pasteeater> is $fname.mp4 or $fname.wav stuttering? [19:11] <Arthur_D> pasteeater: both, if I open the .wav in Audacity there are gaps in the file [19:12] <pasteeater> where does $fname.wav come from? i don't see a ffmpeg command making that [19:13] <Arthur_D> wait, I'll paste the whole file. Somehow I removed that part when I tried to remove the commented lines (there are lots :P) [19:14] <Arthur_D> http://pastebin.com/TwrkcnQ0 [19:16] <zpmorgan> Is there a way to turn a video into a bunch of 1-second audio clips with associated screenshots? [19:18] <zpmorgan> and what are the rawest formats for both images & audio?? [19:48] <zap0> PCM [19:51] <pasteeater> Arthur_D: -threads 0 does nothing for audio [20:08] <Megapixar> any advice on missing lpthread please? http://pastebin.ca/2102735 [20:13] <Megapixar> BTW, on ffmpeg.org is a spelling mistake, under News section: "Januar 5, 2012..." [20:18] <dericed> BTW, on http://ffmpeg.org/libavfilter.html#scale there is a mistake. The sar argument is listed twice. [20:21] <Arthur_D> pasteeater: OK, will remove that then. But I doubt it would matter for the stuttering [20:25] <pasteeater> Arthur_D: same here. ping burek if you ever see him here. he knows more about audio capture than me. [20:27] <Arthur_D> thanks. I've been trying to fix this for a couple days, but I've had no luck. Hopefully burek will know something of help [20:28] <pasteeater> dericed: http://ffmpeg.org/pipermail/ffmpeg-devel/2012-January/119064.html [20:30] <Megapixar> Any advice on missisng pthreads library? getting same arror with 0.9.1 as well. http://pastebin.ca/2102735 [20:31] <JEEB> Megapixar, does it work with -L/usr/lib64 ? [20:33] <Arthur_D> pasteeater: one more thing: about the video output - will the parameters I'm using give the highest possible output quality? I will later edit videos together and I'd like to keep them as lossless as possible [20:34] <pasteeater> if you're editing then use a lossless output that is edit friendly as an intermediate file. [20:34] <pasteeater> i wonder if you can use '-c:a copy' with alsa/pulse input. [20:35] <pasteeater> ...then output from editor as lossless too and re-encode with ffmpeg/x264 (or encode directly from editor if you trust it). [20:36] <Arthur_D> so -acodec copy and -vcodec copy will output to an editor-friendly format? That's why I'm using libx264 since I know I can open it in editors [20:36] <pasteeater> no [20:36] <Arthur_D> what do you suggest to use? [20:37] Action: pasteeater must go afk. tags JEEB into ring. [20:37] Action: JEEB takes out the :effort: card [20:37] <Arthur_D> :D [20:38] <Arthur_D> as you can see, I'm by no means an expert. With audio, I know WAV and FLAC is lossless, but what to use for video I have no idea [20:39] <JEEB> no "normal" H.264 decoder that is in some commercial editor supports lossless H.264, so libx264 is out of the question I guess [20:39] <JEEB> if you're on windows you could use ffvhuff with WAV/PCM in avi [20:39] <Arthur_D> I'm on Linux [20:39] <JEEB> there are video editors on lunix? [20:40] <Arthur_D> why would there not be? [20:40] <JEEB> anyways, that then depends on what library is used to load the clips, and even more importantly -- how old [20:41] <JEEB> anyways, ffvhuff + wav/pcm in avi is a safe bet [20:41] <Arthur_D> I'm using a rolling-release distro, Arch Linux [20:41] <JEEB> since even the old stuff supports that [20:41] <Arthur_D> ok, what extension does it use? [20:41] <JEEB> ? [20:41] <Arthur_D> filename extension [20:41] <JEEB> ffmpeg -i input.derp -vcodec ffvhuff -acodec pcm16lewhatever derp.avi [20:42] <Arthur_D> ok, thanks :) [20:42] <JEEB> you can also test crf 0 libx264 at some point of time with the editor to check if it supports lossless H.264 [20:43] <Arthur_D> alright, sounds good. Now I have two options, thanks :) [20:44] <JEEB> if lossless H.264 works with the editor, you might want to make GOPs shorter, because usually editing means lots of seeking [20:44] <JEEB> and the less frames you have to decode before getting a picture after seeking, the better [20:45] <Arthur_D> um, okay [20:47] <Arthur_D> any reason to use lossless H.264 instead of ffvhuff? [20:48] <JEEB> it compresses better [20:48] <Arthur_D> ok, I will try to see if I can use that then [20:48] <JEEB> ffvhuff is just fast [20:48] <JEEB> very fast [20:48] <JEEB> in both decoding and encoding [20:49] <Arthur_D> hm, well I think it's more compelling to use that then [20:49] <Arthur_D> I've got plenty of disk space [20:49] <Megapixar> JEEB: no, same error. I looked inside /usr/lib64/lpthread.so since its only 222 bytes. http://pastebin.ca/2102744 should I rebuild pthread, if so how would I do that? [20:51] <JEEB> I don't know... haven't dealt with weird multilib distros [21:49] <eightfold> can anyone recommend any more recent and good quality codec shoot-outs. i'm looking at a 2005 shoot-out at doom9. seems to be the latest. [21:54] <pasteeater> eightfold: you might be interested by http://x264dev.multimedia.cx/archives/102 [21:54] <pasteeater> still old, but not as [21:54] <pasteeater> or same time and just use x264 [21:57] <JEEB> s/same/save/ [22:33] <ircdearia> Is there a way I can use ffmpeg to create a v4l2 device so that I can stream/broadcast a video live over network/Internet? [23:13] <eightfold> pasteeater: thanks. are those mighty settings lines necessary when using like ie mpeg-4 asp? isn't there something like lame's --preset or -Vx? [23:14] <pasteeater> eightfold: not really. generally i just use -qscale if encoding with -c:v mpeg4 [23:15] <pasteeater> lower value is higher quality. [23:15] <pasteeater> sane range is 3-5. consider 2 to be visually lossless, IIRC. [23:17] <eightfold> pasteeater: sorry for a stupid question. but is there such a thing as "pure" mpeg-4 asp (as presented in this blog-post). i thought there was only implementations of mpeg-4 part 2 such as xvid divx etc. [23:21] <kriegerod> when ffmpeg prints its stats on _new_ line, instead of rewriting old on the same line, it means it has reconnected? (applying to applehttp stream) [23:46] <epsilon> I need a hint, I'm trying to record through the mic-in of the soundcard: http://paste.debian.net/152069 [23:47] <epsilon> I can hear the sound via alsa and headphone directly, but the recorded file is empty. [23:47] <epsilon> I also tried different hw, codec, sample rate, no effect. Any ideas? [23:55] <ircdearia> loopback is perhaps a useful keyword relative to my question [00:00] --- Fri Jan 13 2012

[00:00] <durandal_1707> i dont know out of head [00:00] <durandal_1707> maybe fourcc [00:00] <durandal_1707> where you found that? [00:02] <OanaStratulat> durandal_1707: Stream #0:1(eng): Video: h264 (Main) (avc1 / 0x31637661) [00:05] <OanaStratulat> durandal_1707: can you point me the line where the duration is calculated? [00:05] <durandal_1707> avc1 is fourcc and 0x31... is its hex representation [00:05] <durandal_1707> OanaStratulat: you need to start reading mov demuxer [00:09] <durandal_1707> michaelni: ffplay -vf format=bgr555le,format=rgb555be fate-suite/dxtory/dxtory_mic.avi [00:10] <durandal_1707> something is not right with endianess and rgb2rgb conversion [00:28] <cbsrobot> OanaStratulat: concerning the bug 599 [00:28] <OanaStratulat> cbsrobot: yes [00:28] <cbsrobot> I think mov.c calculates the duration from the info in the mdhd atom [00:29] <cbsrobot> timescale 5994, duration: 2004952 [00:30] <cbsrobot> but the tkhd (and elst ) atom have a duration of 179700 [00:30] <cbsrobot> so: 179700 / 5994 = 29.81 sec [00:30] <OanaStratulat> yes...that is the correct duration of the file [00:31] <cbsrobot> 2004952 / 5994 = 334 sec [00:31] <cbsrobot> ^ the wrong duration [00:31] <OanaStratulat> so where do you think is the problem? [00:32] <OanaStratulat> the duration in mdhd atom? [00:32] <cbsrobot> before answering this ... some observations I made [00:32] <cbsrobot> quicktime says the file has about 5 fps, but plays it at 60 fps [00:33] <cbsrobot> so quicktime mixes some things up too [00:34] <OanaStratulat> yes [00:34] <OanaStratulat> please have in mind that i started working with ffmpeg 2 weeks ago [00:35] <cbsrobot> and btw the mvhd atom uses timescale: 5994, duration: 179700 [00:36] <OanaStratulat> where does the 2004952 duration come from ? [00:37] <cbsrobot> not sure [00:38] <cbsrobot> I suggest you read http://developer.apple.com/documentation/quicktime/QTFF/qtff.pdf [00:39] <OanaStratulat> it calculates duration on line 765 in mov.c but it is based on the version no ? [00:40] <cbsrobot> read p52: Duration [00:42] <cbsrobot> as I can see in mov.c [00:43] <cbsrobot> the MOVContext timescale is set in mov_read_mvhd [00:44] <cbsrobot> but the MOVStreamContext is set in mov_read_mdhd [00:44] <cbsrobot> and the duration aswell [00:44] <OanaStratulat> they must be in the same place no? [00:44] <OanaStratulat> it uses the timescale for one track with the duration of another one no/ [00:46] <cbsrobot> well - actually it looks correct to me [00:47] <cbsrobot> but I think you can try to set in mov_read_mdhd : [00:47] <cbsrobot> sc->time_scale = c->time_scale; [00:47] <cbsrobot> at the end and see if it fixes the problem [00:47] <cbsrobot> sorry [00:47] <cbsrobot> wrong [00:48] <cbsrobot> timescale is 5994 in both atoms [00:48] <cbsrobot> rather [00:48] <cbsrobot> st->duration = c->duration; [00:49] <cbsrobot> at the end [00:49] <OanaStratulat> the same duration [00:49] <cbsrobot> (I cant tell you the exact linenumer as I'm hacking mov.c in this branch) [00:50] <cbsrobot> *linenumber [00:50] <OanaStratulat> ok so now i have http://pastebin.com/QV7Uvza1 [00:50] <OanaStratulat> this is my output [00:51] <OanaStratulat> http://pastebin.com/bugPg610 [00:51] <OanaStratulat> my diff [00:51] <cbsrobot> Duration: 00:05:34.49, start: 0.000000, bitrate: 2775 kb/s <- still looks wrong [00:52] <OanaStratulat> yes [00:52] <OanaStratulat> but when i av_log the duration looks good [00:55] <cbsrobot> yeah - you need to dig deeper [00:55] <cbsrobot> it was just a hint .... [00:56] <OanaStratulat> so no other ideas ? [01:03] <cbsrobot> not yet [01:03] <OanaStratulat> what is version ? [01:03] <OanaStratulat> because the duration is calculated looking at the version [01:05] <bcoudurier> duration is not based on edit lists [01:05] <bcoudurier> it's what's in the mdhd atom [01:06] <OanaStratulat> i`m now looking at http://wiki.multimedia.cx/index.php?title=QuickTime_container#mdhd [01:09] <cbsrobot> version is a question of 32-bit size or 64-bit size [01:09] <OanaStratulat> yes, found that out [01:10] <OanaStratulat> the duration is calculated correctly from the file, i checked with the versions [01:10] <OanaStratulat> and it`s using the correct function [01:10] <OanaStratulat> maybe the file used it`s the problem ? can it be? [01:11] <cbsrobot> quicktime shows correct duration [01:11] <Daemon404> btw [01:11] <cbsrobot> but who knows what info quicktime shows as duration [01:11] <Daemon404> quicktime will be a dick sometimes [01:11] <Daemon404> and its "Duration" will techncially be wrong [01:12] <Daemon404> cause itll be based off of timecodes instead of timestamps [01:15] <cbsrobot> the duration in the editlist (elst) seems correct for audio and video [01:16] <OanaStratulat> why it`s doing 2 passes of mdhd ? [01:16] <cbsrobot> the only place it seems wrong is the duration in the mdhd atom [01:16] <cbsrobot> audio [01:16] <cbsrobot> video [01:16] <cbsrobot> audio <- pass 1 [01:16] <cbsrobot> video <- pass 2 [01:17] <cbsrobot> or more ccurate [01:17] <cbsrobot> *accurate [01:17] <cbsrobot> pass1: trak 1 [01:17] <cbsrobot> pass 2: track 2 [01:17] <OanaStratulat> so video is wrong [01:17] <OanaStratulat> can be the video header scrammbled in the file ? [01:18] <OanaStratulat> scrambled * [01:18] <cbsrobot> maybe [01:18] <cbsrobot> remove the DEBUG comment at line 25 [01:19] <OanaStratulat> the same duration [01:19] <OanaStratulat> michaelni: ping [01:23] <OanaStratulat> cbsrobot: can be a filed for the audio duration and one for the video and then compare [01:23] <OanaStratulat> and av_log if they are different but still decode the file ? [01:23] <OanaStratulat> this seems to be a viable solution [01:25] <cbsrobot> this sound more like "add a warning" then "fix a bug" [01:26] <OanaStratulat> yes.. [01:27] <OanaStratulat> but suppose the video header is messed up in the file how can i find this out ? [01:28] <OanaStratulat> ffplay shows the same duration [01:31] <cbsrobot> ha - found it [01:32] <cbsrobot> at the end of mov_read_stts [01:32] <OanaStratulat> do not tell me what is, let me try to find it [01:32] <cbsrobot> add [01:32] <cbsrobot> st->duration = c->duration [01:32] <OanaStratulat> ahh [01:32] <OanaStratulat> :)) [01:32] <cbsrobot> but this is the "dirty" solution [01:32] <OanaStratulat> why is that? [01:33] <OanaStratulat> 1st what does mov_read_stts do ? [01:33] <cbsrobot> well - I'm not the mainteiner ... [01:33] <cbsrobot> bcoudurier: what do you think ? [01:33] <bcoudurier> nope [01:34] <bcoudurier> if anything AVFormatContext = c->duration [01:35] <cbsrobot> bcoudurier: can you be a bit more verbose ? OanaStratulat tries to find a good solution for bug 599 [01:36] <OanaStratulat> bcoudurier: it`s for a Google Code In task [01:36] <bcoudurier> sure [01:36] <bcoudurier> setting AVFormatContext->duration to the global mov duration in mvhd is fine [01:39] <OanaStratulat> so if i add st->duration = c->duration at the end of mov_read_stts is it good ? [01:44] <OanaStratulat> bcoudurier: ^? [01:44] <bcoudurier> no [01:45] <bcoudurier> not st->duration, AVFormatContext->duration [01:46] <OanaStratulat> what is the var of AVFormatContext used ? [01:46] <OanaStratulat> AVFormatContext->duration = c->duration; doing like this is wrong i presume [01:46] <bcoudurier> ->duration [01:47] <OanaStratulat> please be more explicit [01:50] <OanaStratulat> bcoudurier: ^ [01:51] <bcoudurier> the var is probably named s but then again it depends on the function :) [01:51] <OanaStratulat> in mov_read_stts there is no var of type AVFormatContext [01:53] <bcoudurier> read_mvhd [01:53] <bcoudurier> you should set it there [01:54] <OanaStratulat> but again here no AVFormatContext variable [01:54] <OanaStratulat> static int mov_read_mvhd(MOVContext *c, AVIOContext *pb, MOVAtom atom) [01:55] <cbsrobot> c->fc maybe [01:56] <OanaStratulat> it messes up duration now, shows 17 secnds [01:56] <OanaStratulat> http://pastebin.com/U0Y1wiYr [01:56] <cbsrobot> read avformat.h:970 [01:56] <OanaStratulat> my diff http://pastebin.com/JGBc4Nap [02:00] <OanaStratulat> cbsrobot: am i doing smth wrong here? [02:08] <OanaStratulat> bcoudurier: ^ [02:13] <OanaStratulat> cbsrobot: it`s not good setting it there it will se the video duration the same as the audio one [02:16] <cbsrobot> OanaStratulat: I'm not sure how to set the AVFormatContext duration correctly [02:16] <OanaStratulat> but doing as you said the 1st time is not corect ? [02:16] <OanaStratulat> correct * [02:17] <cbsrobot> maybe someone else can shed some light in it [02:17] <cbsrobot> nope [02:17] <cbsrobot> it was just finding where the wrong values come from [02:18] <cbsrobot> but the fix should be somewhere else [02:18] <OanaStratulat> maybe bcoudurier can enlighten us [02:19] <cbsrobot> I thought the AVFormatContext duration = time_scale * duration [02:19] <cbsrobot> but it's not [02:21] <bcoudurier> avformatcontext duration scale is different it's in AV_TIME_BASE [02:23] <OanaStratulat> bcoudurier: AV_TIME_BASE how can be calculated ? [02:23] <bcoudurier> you can use av_rescale [02:23] <bcoudurier> AV_TIME_BASE is a constant [02:24] <OanaStratulat> how exactly can i do that with c->duration ? [02:25] <cbsrobot> bcoudurier: thanks [02:25] <cbsrobot> in ...mvhd... add: [02:25] <cbsrobot> c->fc->duration = av_rescale(c->duration, AV_TIME_BASE, c->time_scale); [02:26] <OanaStratulat> cbsrobot: yes, it`s working now [02:27] <OanaStratulat> bcoudurier: cbsrobot thx for the help [02:32] <cbsrobot> OanaStratulat: patch ready ? [02:32] <OanaStratulat> upload it on trac? [02:33] <cbsrobot> or directly to the ml mentioning ticket599 [02:34] <OanaStratulat> cbsrobot: https://ffmpeg.org/trac/ffmpeg/attachment/ticket/599/0001-Fixes-wrong-durat… [02:36] <cbsrobot> hmm [02:37] <cbsrobot> i'd put it directly after [02:37] <cbsrobot> c->duration = (version == 1) ? avio_rb64(pb) : avio_rb32(pb); /* duration */ [02:37] <cbsrobot> so it's easier to read [02:37] <OanaStratulat> so amend to patch ? [02:39] <cbsrobot> and maybe a little comment above it would be nice [02:40] <OanaStratulat> what should i say in the comment? [02:40] <cbsrobot> I let you think about that [02:41] <OanaStratulat> cbsrobot: //duration calculated from c->duration converted to AV_TIME_BASE sounds good? [02:42] <cbsrobot> nah - sounds too much like me commenting something [02:42] <cbsrobot> maybe [02:43] <cbsrobot> Set the AVFormatContext duration because the track duration is not accurate [02:43] <OanaStratulat> ok [02:45] <OanaStratulat> resend on ML? [02:45] <cbsrobot> and you can also mention the "Similar to what Quicktime shows" when you send the mail [02:45] <cbsrobot> do you use git send-email ?

[14:08] <OanaStratulat> regarding this file, the adx var gets 0. it always should be > 0 but i cannot figure out why it gets like this [14:08] <ubitux> hi saste [14:08] <ubitux> saste: i'm testing your audio -show_frames patch, but i have a crash [14:09] <saste> ubitux: sample/bt?

[14:18] <OanaStratulat> ubitux: some thought regarding the file i`ve pointed out ? [14:19] <ubitux> OanaStratulat: i'm waiting for your observations and specific questions before looking at the code :P [14:20] <OanaStratulat> from the bt i see that the adx var is 0. adx is calculated from a difference of x1-x0 but i do not understand why those are equal at some point. [14:20] <saste> ubitux: no need, my MP3s crash it, thanks for spotting [14:22] <ubitux> ok :) [14:23] <ubitux> OanaStratulat: not sure i'll be of much help but i'll have a quick look in a moment [14:23] <ubitux> saste: btw, i think the we might want to limit the packet/frames to audio or video only [14:26] <OanaStratulat> ubitux: ok thx [14:27] <ubitux> OanaStratulat: is it a zzuf file? [14:28] <OanaStratulat> ubitux: BBB from libav uploaded the file [14:28] <cbsrobot> I get http://pastebin.com/3W4ETVfU when compiling - any ideas ? [14:34] <ubitux> OanaStratulat: you need to understand how the codec works to fix this one [14:35] <ubitux> i can't help much without taking the time to read some doc, and i don't have that time unfortunately [14:35] <OanaStratulat> where can i find the documentation for the codec ? [14:35] <OanaStratulat> on multimedia wiki ? [14:36] <ubitux> vorbis mmh, i guess xiph.org? [14:36] <ubitux> http://www.xiph.org/vorbis/doc/ [14:37] <ubitux> http://www.xiph.org/vorbis/doc/Vorbis_I_spec.html [14:37] <ubitux> you'll need to take some time to understand what is the function doing and supposed to do [14:45] <OanaStratulat> ubitux: that functions draws the line described in page 45 of http://www.xiph.org/vorbis/doc/Vorbis_I_spec.pdf [14:45] <OanaStratulat> and the problem is that a line cannot be drawn within a point, the line from x0 x1 is 0 [14:46] <ubitux> ok well spotted [14:47] <av500> so find out why x0 and x1 are equal [14:47] <ubitux> it shouldn't be hard to deal with a simple point [14:47] <ubitux> av500: i guess the function should be able to deal with a line which is actually a single point [14:47] <ubitux> but i don't know the codec at all [14:48] <av500> OanaStratulat: didnt we have the same discussion in #libav?

[14:51] <av500> and, what is the result in the failing case? [14:51] <OanaStratulat> x1 is 3 and samples are 1024 in the failing case [14:51] <av500> and lx? [14:51] <av500> also 3?

[14:57] <OanaStratulat> is the problem that those lines intersect each other at one point? [14:58] <OanaStratulat> or i`m thinking it wrong [14:58] <av500> does the spec allow 2 times the same x value? [14:58] <av500> if yes, the vorbis decoder is wrong [14:59] <av500> if not, the decoder should complain [14:59] <OanaStratulat> i do not know that, i do not see any comments of the same value of x in the spec [15:04] <OanaStratulat> av500: do you know something about this ?

[15:24] <ubitux> just like any other decoder failure? [15:24] <OanaStratulat> av_log the message and return invalid data? [15:24] <ubitux> also i'm not sure you should end the program if it can still continue [15:24] <ubitux> better raise a warning and deal with it [15:25] <OanaStratulat> ubitux: All vector [floor1_x_list] element values must be unique within the vector; a non-unique value renders the stream undecodable [15:25] <OanaStratulat> this is in the documentation of vorbis [15:25] <ubitux> yes, but some ppl might want to play the video anyway [15:26] <ubitux> so if there is some duplicated element values, maybe it's a transmit error or any other random reason [15:26] <OanaStratulat> the file is not playable even in vlc [15:26] <ubitux> ignore the element, or ignore the frame, and just play the rest [15:26] <OanaStratulat> how can i do that? [15:26] <ubitux> isn't vlc using the libavcodec codec? [15:27] <OanaStratulat> don`t know that [15:27] <av500> ubitux: maybe they use libvorbis [15:27] <ubitux> can't you just skip the duplicated element? [15:28] <OanaStratulat> that function makes lines between every x and the computed y, and they are dependable with the previous one [15:28] <OanaStratulat> is one value is wrong and i use the previous one i make the stream fuzzed [15:29] <av500> OanaStratulat: see vorbisdec.c: [15:29] <av500> av_log(vc->avccontext, AV_LOG_ERROR, "Invalid floor type!\n"); [15:29] <av500> return AVERROR_INVALIDDATA; [15:29] <ubitux> OanaStratulat: can you do some interpolation and raise a warning? ;) [15:30] <OanaStratulat> what is interpolation? [15:30] <ubitux> guessing the value [15:30] <ubitux> basically. [15:30] <ubitux> :p [15:30] <av500> just stop decoding that frame and return an error [15:30] <ubitux> yes should do the trick too :) [15:31] <OanaStratulat> the x value are given with the file [15:31] <av500> dont interpolate anything [15:31] <ubitux> can't you just raise a warning and return just like av500 proposed a few times already? [15:31] <av500> av_log and return an error [15:32] <OanaStratulat> it`s a void function how can i end it ? [15:32] <ubitux> "return;" [15:33] <av500> OanaStratulat: its not cast in stone to be void [15:33] <av500> not part of the 10 commandments [15:34] <av500> in other words, it's called *soft*ware for a reason :) [15:34] <ubitux> that's true in that case, but in a lot of case it might break api & abi [15:34] <ubitux> so it's as frustrating as hardware [15:34] <ubitux> :( [15:35] <av500> I dont think codec internal functions are part of any ABI/API [15:35] <av500> at least not in lavc [15:35] <ubitux> yes as i said, it doesn't apply here [15:35] <ubitux> that was just a generic unjustified complain [15:36] <ubitux> life is hard [15:36] <OanaStratulat> av500: if i exit_program(1); ? [15:36] <OanaStratulat> av log and exit_program(1); ? [15:36] <av500> no [15:36] <av500> of course not [15:37] <av500> OanaStratulat: have a look at the call chain that leads to the error [15:37] <OanaStratulat> in ff_vorbis_floor1_render_list i must put the check there it computes everything [15:37] <av500> in fact, you dont even need to add the av_log [15:37] <av500> its already there [15:40] <OanaStratulat> av500: is it good like this http://pastebin.com/W9eDdTpn ? [15:40] <av500> looks like overkill [15:42] <OanaStratulat> how to check for the same value in another manner ? [15:42] <ubitux> juste change the prototype of the /0 function and returns a negative value when it happens [15:42] <ubitux> then you raise the error [15:42] <OanaStratulat> ubitux: please be more explicit [15:42] <ubitux> make render line return a value [15:43] <ubitux> return 0 in normal case, return -1 if adx is 0 [15:43] <ubitux> in floor1_render_list, you check the return value of render_line [15:43] <ubitux> and raise it in case it's not zero [15:43] <ubitux> or sth like that [15:43] <OanaStratulat> ok [15:44] <av500> OanaStratulat: we are not after writing a vorbis verifier [15:44] <av500> we want the thing not to crash and be robust [15:44] <OanaStratulat> so how must i do it correctly ? [15:45] <av500> well, as you found out, you divide by adx = 0 [15:45] <OanaStratulat> i found out the bug, but now how is the best way to repair it [15:45] <OanaStratulat> this is lead by having the same x valye [15:45] <OanaStratulat> value [15:46] <OanaStratulat> av500: http://pastebin.com/BLzisMU7 doing like this it does not crash anymore [15:47] <av500> yes, but why return a value then at all? [15:47] <av500> since the return value is not checked [15:47] <av500> and usually return 0 is used for success [15:52] <OanaStratulat> av500: http://pastebin.com/NYNLSMkM [15:52] <OanaStratulat> av500: opinion about this ? [15:53] <av500> again the error is not propagated [15:54] <ubitux> or not enough :P [15:54] <av500> [15:37:13] <av500> OanaStratulat: have a look at the call chain that leads to the error [15:54] <OanaStratulat> and check for the error in another place ? [15:54] <ubitux> (indent is wrong too btw) [15:55] <ubitux> OanaStratulat: int ret = render_line(...); if (ret < 0) return ret; [15:55] <ubitux> if floor1_... fails, you need to raise the error too. [15:55] <OanaStratulat> ok ubitux, i must go now. i`ll look into this problem later. thx for the advice [15:56] <ubitux> heh, i never know how much we are supposed to explain [15:58] <Compn> ubitux : which email addy ?

[00:00] <mgeary> so, i've been given a h264 video, which i realize isn't a good intermediary format (though it's a great final delivery format). I need to make some smaller versions of this video that will then be encoded for web delivery. What is a good codec to use to keep as much quality as possible, given that i'm already dealing with a compressed source file? [00:00] <mgeary> in other words, what format should i use if my objective is preserving quality, not having an acceptable end-user experience? [00:00] <newl> webm is my favorite of the month [00:00] <mgeary> s/format/codec(s) [00:01] <mgeary> mmm. i'm dealing with some non-*nix people on the receiving end of this, i don't know if they'll have the ability to convert webm. Any other suggestions? [00:01] <newl> get ffmpeg.exe :) [00:02] <relaxed> mgeary: {h264/aac}.mp4 served via flashplayer [00:02] <newl> relaxed: that was last months favorite [00:02] <mgeary> relaxed: but h264 is a rather lossy format, no? One that is optimized for playback, not necessarily retention of quality. I would have thought something like a high-quality motionJPEG... [00:05] <relaxed> 1) h264 is the best lossy codec 2) you're not servering lossless video over the web 3) the alternatives are {theroa/vorbis}.ogv and {vpx/vorbis} via html5. [00:05] <darkstarbyte> h.264 is very good lossy also [00:05] <mgeary> this isn't for web delivery. This is for delivery to someone else who will encode what i give them into several derivatives [00:05] <JEEB> something lossless then [00:05] <mgeary> i'm looking for an archival format, not a delivery format [00:06] <mgeary> right. such as? [00:06] <JEEB> be it lossless H.264, ffvhuff or ffv1 [00:06] <relaxed> oh, "encoded for web delivery" confused me. [00:06] <darkstarbyte> I was not here for the whole thing, but vp8 is great for animation [00:06] <mgeary> okay, so "-vcodec libx264 -vpre lossless_fast" is really lossless? [00:07] <JEEB> -vcodec libx264 -crf 0 is lossless :V [00:07] <JEEB> (with 8bit H.264) [00:07] <mgeary> ok, thanks [00:07] <JEEB> if you have a >8bit build of libx264, then you need to set qp to zeor [00:07] <JEEB> *zero [00:07] <JEEB> (as crf values go below zero with >8bit) [00:07] <JEEB> but I'm pretty sure you'll only be dealing with 8bit [00:07] <JEEB> thus -crf 0 is fine [00:08] <mgeary> also, does anyone here have experience compiling from git on OS X? my previous attempt worked fine, but with the latest code i'm getting this: http://dpaste.com/685584/. i did a pull of x264 and re-compiled and installed that with no problems, but i still get this error from ffmpeg [00:08] <darkstarbyte> I use Linux, but the command line is very similar [00:09] <darkstarbyte> If you have git installed then [00:09] <mgeary> right. i know how to do it, but i don't know how to deal with this particular error [00:09] <mgeary> if i leave out x264, it compiles fine [00:09] <relaxed> make distclean [00:09] <darkstarbyte> I know how to compile x264, but I am not sure how to install it on macosx [00:09] <relaxed> then try again [00:10] <mgeary> did "make clean", but i'll try "make distclean" and try again [00:11] <mgeary> "./configure --enable-libmp3lame --enable-gpl --enable-libx264" works just fine [00:14] <DrGorilla> hi [00:18] <mgeary> nope. same error :( [00:27] <DrGorilla> so is ffserver sutable for streaming video files yet? the documents say it has problems [00:28] <JEEBsv> it might work, but it certainly isn't kept up nor does it have documentation [00:28] <JEEBsv> thus I'd prolly recommend VLC for streaming in most cases [00:29] <DrGorilla> what about vlc vs gstreamer? [00:29] <JEEBsv> vlc [00:29] <DrGorilla> ok [00:30] <JEEBsv> I don't really see gstreamer as a great alternative at this point of time [00:30] <JEEBsv> it might have become better, but that's my personal opinion on it >_> [00:30] <DrGorilla> its complicated and im not having fun with the docs [00:30] <JEEBsv> VLC is the thing that most people use for http/rtsp streaming and the likes [00:31] <JEEBsv> lets you set libx264's settings nowadays nicely as well [00:31] <JEEBsv> watching your Japanese TV tuner's stuff from 8000km away is lovely :D [00:33] <DrGorilla> ive got an archive of video in a custom file format and i want to put a rest api with a video server on it, ive been playing with vlc, ffserver, and gstreamer and they are all kind of a pain - i need to create a custom input plugin but i would like to just use a tool to stream frames to a pipe or stdout and into a video server - id like to use php to serve the streams [00:34] <DrGorilla> do you happen to know of any examples or something? [00:34] <mgeary> have you looked at Red5 at all? [00:34] <DrGorilla> nope [00:34] <DrGorilla> thanks i will check it out [00:34] <mgeary> it's a replacement for the Flash Media Server. i've never used it for HTML video, but it may work for that as well [00:35] <DrGorilla> interesting, thanks [00:36] <DrGorilla> it looks like its flv [00:36] <mgeary> it also does mp4 [00:36] <DrGorilla> oh ok [00:37] <DrGorilla> let me ask you this, say i have frames already encoded in dixv, but it has custom headers - whats the best container i could put them in to enable video streaming? [00:39] <mgeary> on that i have no experience or ideas, i'm afraid. But others here probably would [01:18] <stopppppa> would it be possible to put a AAC Internet Radio stream into a MP4 container? with or without FFMPEG, does that make sense even? [01:31] <newl> internet radio stream -> mp3 [01:44] <stopppppa> newl: there are streams that are aac [01:44] <stopppppa> newl: heres one: http://icy1.abacast.com:80/eldorado-ksly-64 [01:47] <newl> stopppppa: yes - when i play it is a aac and when i dumpstream it to a mp3 file and then play that it is still an aac - [01:47] <cbreak> of course [01:47] <cbreak> what did you expect? :) [01:47] <newl> i was stating that - he wants to put it into some other container [01:48] <newl> does he want to convert it? that is a different question [01:48] <cbreak> it sounded like he wanted to remux it [01:48] <stopppppa> my understanding is the stream is in raw aac format [01:49] <stopppppa> it doesn't have a container [01:49] <stopppppa> I'd like it to have a MP4 container [01:49] <stopppppa> on the fly conversion would be the solution, but not sure if that is possible or makes sense [01:50] <newl> is ksly an all country all the time station? [01:50] <stopppppa> that would be my guess [01:51] <newl> i'll move it to my country folder then -> /dev/null [01:52] <newl> what about piping it from an mplayer dumpstream into ffmpeg -i *.mp4 [01:53] <stopppppa> newl: not a bad idea... but i would like to do this programmatically [01:53] <stopppppa> its seems like ffmpeg would do the job [01:54] <newl> does programmatically mean in a script ? use pipes [01:54] <stopppppa> no i mean using c code or java code [01:54] <stopppppa> ffmpeg code would be nice [01:54] <stopppppa> but not sure if it handles things like that, meaning infinite streams [01:55] <newl> use exec - if you want to use fpc - let me know - that is my main reason for living - using mplayer to get internet radio streams [01:56] <newl> i use pkill as a timer to set the 'recording' time [01:56] <newl> sleep and then pkill [01:56] <stopppppa> exec? fpc? sorrry new terms to me [01:57] <newl> there is options for mplayer and mencoder - for timing - one didn't have it when i was programming this [01:57] <newl> exec -> system exec for a string exec 'mplayer .... [01:57] <newl> fpc = freepascal [01:58] <stopppppa> cool. thanks for the input newl [01:58] <stopppppa> still open to suggestions if anyone has any bright ideas on where to look in the FFMPEG code [01:58] <newl> c and all languages can execute strings [02:00] <newl> except javascript - but i saw some trick with it [02:03] <stopppppa> newl: so technically if I had a ffmpeg binary on the system and made an exec call it could work [02:04] <newl> sure [02:07] <newl> http://pubs.opengroup.org/onlinepubs/009604499/functions/exec.html [02:07] <newl> http://pubs.opengroup.org/onlinepubs/009604499/functions/system.html [02:36] Action: newl using ffmpeg with exec also hides the actual ffmpeg code from prying non debugger eyes or people who know how to use strings .. knowledge is power [03:27] <DrGorilla> anyone familiar with rtmpdump or live555? [03:27] <newl> rtmpdump needs command line improvement [03:28] <DrGorilla> i mean as a library to create a simple server with [03:28] <newl> what does this simple server do [03:28] <DrGorilla> serve video [03:29] <newl> icecast? [03:29] <newl> http [03:30] <DrGorilla> http rtmp [03:31] <newl> i use rtmpdump to get cspan2 - there has to be a better way to serve videos [06:10] <Arthur_D> hi, I'm trying to re-play a glc output file with glc-play and pipe it to ffmpeg which will encode the output to a usable format. However, it fails with "pipe:: Invalid data found when processing input". Full command and output: http://pastebin.com/JcWMCwXH [06:11] <Arthur_D> it should supposedly work; found the method here: https://qubodup.wordpress.com/2010/06/02/record-an-opengl-game-in-linux-usi… [06:13] <relaxed> do you get any errors when dumping it without the pipe? [06:13] <Arthur_D> what do you mean? [06:13] <relaxed> -o file [06:14] <Arthur_D> you mean ffmpeg -i supertuxkart-32700-0.glc ? [06:15] <Arthur_D> I get the same result [06:15] <Arthur_D> I think the problem is that glc has its own format, which can be played with glc-play, but somehow piping it to ffmpeg doesn't work [06:16] <relaxed> glc-play /home/magne/SuperTuxKart/Videos/glc-tmp/supertuxkart-32700-0.glc -o OUTPUT.FILE -y 1 [06:16] <Arthur_D> nothing happens [06:17] <Arthur_D> I'm not sure what glc-play actually does [06:18] <relaxed> it doesn't output anything? [06:18] <Arthur_D> no [06:19] <Arthur_D> hmmm... "-y, --yuv4mpeg=NUM save video stream NUM in yuv4mpeg format" - and the -y flag is used [06:19] <relaxed> then we've ruled out a ffmpeg problem [06:20] <Arthur_D> right [07:20] <Arthur_D> ok, now I've got a real ffmpeg issue: when I record sound with it, the resulting file is choppy [07:22] <Arthur_D> i.e. doesn't play back smoothly, and when looking at it in Audacity I can see it has gaps here and there [07:25] <relaxed> are you piping? [07:29] <Arthur_D> no [07:29] <Arthur_D> but I start to audio record with ffmpeg at the same time I start recording with glc [07:30] <Arthur_D> so perhaps there are buffer problems [07:37] <Arthur_D> any suggestions? [08:00] <Arthur_D> hmphf, ffmpeg -list_devices true -f openal -i dummy out.ogg as suggested in the ffmpeg man page does not even work [08:29] <Arthur_D> sound problem the same when using rec for audio. Can increasing buffer size mitigate the problem? [09:21] <iandriyanov> Hi all! [09:21] <iandriyanov> Pls help me with install ffmpeg [09:22] <iandriyanov> Me need old version (svn checkout -r13180 svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg) [09:23] <iandriyanov> But svn say "svn: warning: URL 'svn://svn.mplayerhq.hu/mplayer/trunk/libswscale' at revision 34540 doesn't exist" [09:23] <iandriyanov> And ./configure say error - FAAD test failed [09:23] <iandriyanov> What's wrong? [09:25] <iandriyanov> Hey...anybody [09:27] <Arthur_D> http://svn.mplayerhq.hu/ffmpeg/trunk does not appear to exist, so I guess it's not there anymore then [09:28] <Arthur_D> try to ask their mailing list: http://svn.mplayerhq.hu/design7/mailing_lists.html [12:05] <Ginks> Could I have someone take a look at: http://pastebin.com/HDFuTk2A It deals with adding a -vf to an existing -vf for an overlay [12:07] <Ginks> Oh, and in the last sentence I ment to say video, not image [12:34] <cbreak-work> what is the general expected lifetime of data of which pointers are passed to ffmpeg? [12:34] <cbreak-work> for example av_interleaved_write_frame() [12:35] <cbreak-work> must the AVPacket live on, or is the data copied/encoded syncronously? [14:15] <Milos> So I have a 320kbps mp3 [14:15] <Milos> I'm trying to convert it to 128kbps CBR [14:15] <Milos> I use -minrate -maxrate and -b all set to 128k [14:15] <Milos> keep saying output bitrate = 64kbps [14:15] <Milos> why and how do I get it to do what I want [14:23] <Mavrik> Milos, please paste your commandline and all ffmpeg output to a pastebin :) [14:23] <Milos> Mavrik, I got it! I had to use -ab [14:24] <Milos> which apparently stands for "audio bitrate" and not "average bitrate" [14:24] <Mavrik> Milos, new versions prefer -b:v and -b:a [14:24] <Milos> because apparentely the liblame stuff is not the same as typical ffmpeg switches [14:24] <Milos> ahh ok [14:24] <Mavrik> and "-ab" is typical for older ffmpeg versions :) [14:57] <Milos> Mavrik, cool cool [14:57] <Milos> Mavrik, thanks [14:57] <Milos> btw I am using version numbeeeeer [14:57] <Milos> 0.7.8 [14:57] <Milos> so that explains it [14:57] <Milos> given the latest is somewhere in the 9s [14:58] <Mavrik> yeah, repository versions are ancient [16:21] <iOOO9> is there a plain MPEG-4 ASP encoder, or is ASP only available as XviD, DivX etc? [16:57] <Arthur_D> I'll ask again: anyone know how to reduce stuttering when recording audio with ffmpeg? The resulting file is always choppy when I record video with glc and sound with ffmpeg of a game [17:17] <christo_m> Hello, has anyone had success using WinFF for batch conversion of flv to mp4? [19:07] <Freakshow> nice to see the av_log output \r fixed [19:38] <ioni> hey guys [19:38] <WangDangerly> hello [19:39] <ioni> i have hard time compiling ffmpeg with debug symbols [19:40] <ioni> vlc crashes with hardware acceleration enabled with ffmpeg git [19:42] <ioni> it crashes in libavcodec.so.53 but that's stripped [19:43] <ioni> yey for --disable-stripping [19:49] <ioni> http://paste.xinu.at/7iB/ [19:49] <ioni> trace log [19:49] <ioni> start_frame (avctx=0xac965c40, buffer=0x0, size=0) at libavcodec/vaapi_h264.c:234 [19:49] <ioni> not cool [21:34] <iive> michaelni: take a look ioni's problem. [21:34] <ioni> i have one more step! [21:34] <ioni> wait for me [21:35] <ioni> stupid laptop, is too slow [21:35] <iive> ioni: can you reproduce the problem if you don't use threading? [21:35] <ioni> iive, is threading enabled by default? [21:35] <iive> #3 is frame_worker_thread and #4 is pthread... [21:36] <iive> #4 is start_thread() [21:36] <ioni> hmm [21:37] <ioni> let me look in vlc to see if i can disable [21:37] <ioni> i don't know how to use ffmpeg with libva for playing [21:37] <iive> #0 shows vactx = 0, that looks kind of wrong. [21:39] <ioni> it will be funny to be a one line change as it was last time :) [21:49] <iive> btw, ioni , do you know if vlc uses h264_vaapi codec, or switches pix_fmt by avct->get_format() ? [21:49] <ioni> no idea [21:51] <ioni> c3513477bbbc0898e8fe38c4e37ac67298d76a48 is the first bad commit [21:51] <ioni> commit c3513477bbbc0898e8fe38c4e37ac67298d76a48 [21:51] <ioni> Author: Shitiz Garg <mail(a)dragooon.net> [21:51] <ioni> Date: Sat Dec 31 03:48:53 2011 +0530 [21:51] <ioni> cook: K&R formatting cosmetics [21:51] <ioni> iive, [21:51] <iive> huh?! cosmetics broke code!! [21:52] <durandal_1707> i doubt ioni uses cook at all [21:52] <iive> cook is audio codec, afair [21:52] <ioni> let me try to revert that [21:52] <durandal_1707> try reverting whole merge [21:54] <ioni> yes [21:54] <ioni> http://git.videolan.org/?p=ffmpeg.git;a=blobdiff_plain;f=libavcodec/cook.c;… [21:54] <ioni> i'll revert this [21:55] <durandal_1707> that is single commit, i doubt it will help [21:56] <ioni> hmm [21:56] <ioni> i failed at bisecting i guess [21:57] <durandal_1707> revert whole merge with that commit inside [21:57] <ioni> which one? [21:57] <ioni> http://git.videolan.org/?p=ffmpeg.git;a=commit;h=1a6a088f7c7b164042ad16d43d… ? [21:58] <durandal_1707> i see nothing bad with that one [21:58] <durandal_1707> ioni: what is actually your problem? [21:59] <ioni> vlc crashes when hardware acceleration is enabled [21:59] <ioni> with git master [21:59] <ioni> http://paste.xinu.at/7iB/ [21:59] <ioni> gdb trace [22:00] <durandal_1707> where is merge with cook file cosmetics changes? [22:01] <michaelni> ioni, did you try disabling threads ? [22:01] <ioni> michaelni, i don't know how to do it [22:01] <durandal_1707> better give whole bisecting history [22:02] <michaelni> -threads 1 for ffmpeg, dunno how todo it in vlc [22:02] <ioni> durandal_1707, http://paste.xinu.at/haSy/ [22:02] <ioni> michaelni, how do use ffmpeg + libva for playing? [22:04] <michaelni> reverting the options.c part of e4e30256f87f177decf59b59e923d05ef64147df should disable therads [22:05] <ioni> let me try [22:11] <ioni> michaelni, yes, that's it [22:24] <ioni> michaelni, i'll revert this in our package [22:24] <ioni> until is fixed properly [23:22] <ioni> michaelni, let me know if you need any more details [23:30] <michaelni> ioni, i mailed the vaapi maintainer about the bug ... [23:30] <ioni> on a ml or private? [23:31] <ioni> michaelni, i want to follow the subject [23:32] <michaelni> ioni, private :( ill reply and CC to you if you tell me your email address [23:33] <ioni> ibiru(a)archlinux.org [23:33] <michaelni> ok, moment [23:34] <michaelni> reply sent [23:36] <ioni> thanks [23:37] <ioni> for now i'll push a package that disables multithread [00:00] --- Thu Jan 12 2012
