[01:08] <burek> how can i roll back my local git repos to a certain revision and recompile ffmpeg [01:16] <Compn> burek : git --reset something [01:17] Action: Compn forgets syntax [01:17] <durandal_1707> git checkout revision-number [01:40] <burek> thanks [01:40] <burek> after i do git checkout rev [01:40] <burek> do i need to do anything else [01:40] <burek> or all the files are already fixed [01:40] <burek> rolled back [01:41] <funman> it's ok but i advise a bit of rtfm even if git can be confusing [01:46] <CIA-40> ffmpeg: 03Ronald S. Bultje 07master * r4ff6dea390 10ffmpeg/libavcodec/x86/pngdsp.asm: pngdsp: swap argument inversion. [01:46] <CIA-40> ffmpeg: 03Ronald S. Bultje 07master * r9b027c0d07 10ffmpeg/libavcodec/ (dsputil.h utils.c): [01:46] <CIA-40> ffmpeg: dsputil: set STRIDE_ALIGN to 16 for x86 also. [01:46] <CIA-40> ffmpeg: This fixes crashes in e.g. PNG decoding with SSE2 enabled. In fact, many [01:46] <CIA-40> ffmpeg: x86 optimizations for codecs assume that our buffer strides are 16-byte [01:46] <CIA-40> ffmpeg: aligned. [01:46] <CIA-40> ffmpeg: 03Diego Biurrun 07master * r0144fe6995 10ffmpeg/ (13 files in 5 dirs): [01:46] <CIA-40> ffmpeg: Remove Sun medialib glue code. [01:46] <CIA-40> ffmpeg: It is obscure, most likely unused and not bit-exact compared to [01:46] <CIA-40> ffmpeg: libavcodec due to a different IDCT transform algorithm. [01:46] <CIA-40> ffmpeg: 03Alex Converse 07master * r314af0ff94 10ffmpeg/ (libavcodec/aacdectab.h libavutil/audioconvert.h): (log message trimmed) [01:46] <CIA-40> ffmpeg: aacdec: Use correct speaker order for 7.1. [01:46] <CIA-40> ffmpeg: The spec says the following speaker mapping is default: [01:46] <CIA-40> ffmpeg: center front speaker [01:46] <CIA-40> ffmpeg: left, right center front speakers, [01:46] <CIA-40> ffmpeg: left, right outside front speakers, [01:46] <CIA-40> ffmpeg: left surround, right surround rear speakers, [01:46] <CIA-40> ffmpeg: 03Ronald S. Bultje 07master * rce1e250ee9 10ffmpeg/libavcodec/x86/ (h264_idct.asm h264_intrapred.asm): [01:46] <CIA-40> ffmpeg: h264: manually save/restore XMM registers for functions using INIT_MMX. [01:46] <CIA-40> ffmpeg: On Win64, these registers are callee-save, so not saving/restoring them [01:47] <CIA-40> ffmpeg: Deprecate avcodec_encode_video(). [01:47] <CIA-40> (26 lines omitted) [04:19] <Mista_D> what's a better gcc version for ffmpeg on Centos? requiring least patches for faac/x264/lame/xvid/... ? [13:15] Action: Compn searches documentation [13:15] <Compn> does ffmpeg have an option to disable index ? say for accessing large avi file over slow network ? [13:16] <Compn> mplayer has -noidx [13:16] <av500> you dont need to read the whole file to get the index :) [13:18] <Compn> right, but the index is at the end [13:18] <Compn> and i dont want it seeking back there [13:19] <av500> does lavc read avi using the index? [13:20] <Compn> i am pretty sure lavf reads the avi index. [13:20] <Compn> altho i have not verified this [13:21] <Compn> since reading avi indexes is a standard thing for all players i've ever heard of [13:21] <Compn> lavf obviously does not need an index to play, if one is not found however [13:22] <av500> my avi player does not read the index for playing :) [13:23] <av500> noidx might make sense for avi and asf [13:23] <av500> for mp4 you need it [13:23] <Compn> yes mp4 needs it [13:23] <Compn> i cant remember mkv [13:23] <av500> not needed to play [13:23] <Compn> right [13:23] <Compn> anyways, thats in response to this bug > https://ffmpeg.org/trac/ffmpeg/ticket/986 [13:24] <av500> but that asks to disable all seeking [13:26] <Compn> i dont think the user knows what he wants, so i guess what his problems are [13:27] <Compn> and yes, he did hit the mp4 over pipe problem with index being at the end. his command line said ffmpeg -i out.mkv but his error said [mov,mp4,m4a,3gp,3g2,mj2 @ 01988da0] moov atom not found . [13:27] <Compn> tricky users :) [13:27] <Compn> make me re-read things [13:27] Action: Compn goes afk [14:06] <SvenL-> Yeah sure ProRes lives ! Where can I have find """"official"""" infos ? Looked at the the gmane ml archive, the git and some forum threads, is there any other place for infos ? [14:21] <overflow_0f8b> hi [14:21] <overflow_0f8b> gcc does not evaluate my 3x3 multiply 3x3 matrix by 3x3 matrix macro at compile time :( [14:22] <overflow_0f8b> ( it does with 2x2 matrix rotation ) [14:24] <av500> #gcc? [14:25] <Tjoppen> also: write a generator? [14:26] <overflow_0f8b> av500<< chan is +R cant talk there [14:27] <overflow_0f8b> so i'm skipping it [15:55] <Compn> SvenL- : you mean prores internal info ? [15:55] <Compn> or specs/ docs ? [15:56] <SvenL-> prores with ffmpeg, just wondering if there is a place I missed for some info [15:56] <Compn> there is the wiki [15:57] <Compn> http://wiki.multimedia.cx/index.php?title=Apple_ProRes [15:58] <Compn> is that what you are looking for? or something else? how to use prores decoder with ffmpeg ? its already in ffmpeg, if your ffmpeg does not decode prores, you may have to upgrade [15:58] <Compn> and if you are using latest git ffmpeg and still having problems with some prores file, you should probably file a bug and upload a sample so ffmpeg can fix it :) [15:59] <SvenL-> okay, thanks a lot, that's exactly what I was looking for [15:59] <SvenL-> I saw a link to this wiki on a thread about prores, but the address doesn't "sound" like ffmpeg, so i didn't dig this way haha [15:59] <Compn> hehe [16:00] <SvenL-> while I'm at it I checked for this : http://wiki.multimedia.cx/index.php?title=REDCode Interesting [16:00] <Compn> wiki.multimedia.cx is run by a xine developer , who is also an ffmpeg developer :) [16:00] <SvenL-> Oh okay [16:01] <Compn> just its on his server instead of ours :) [16:01] <SvenL-> so that's *the* place for ffmpeg doc ? [16:02] <Compn> yes, theres some other pages too [16:02] <Compn> http://wiki.multimedia.cx/index.php?title=Mirrored_Files [16:02] <Compn> thats for official specs [16:02] Action: Compn digs up other url [16:02] <SvenL-> I may be able provide a small sample of .R3D footage of recent RED cameras [16:02] <Compn> that would be nice , i think RED codec is on our list to reverse engineer [16:02] <SvenL-> uhm [16:04] <Compn> michaelni keeps some of his documents here : http://www1.mplayerhq.hu/~michael/ [16:04] <SvenL-> so as is it can't playback ? [16:05] <Compn> i havent tested red codec, let me see. [16:06] <SvenL-> Ha the doc says it's a "special" JPEG2000 file [16:07] <Compn> it gives error with my ffmpeg [16:07] <SvenL-> Okay [16:07] <Compn> but i dont have latest version [16:07] <JEEBsv> just like DV is a "special" version of MJPEG? [16:07] <Compn> hmm? [16:08] <Compn> i think it means like rv40/wmv3 are special versions of mpeg4 asp :P [16:08] <SvenL-> yes [16:08] <SvenL-> I think too [16:08] <Compn> modified, proprietary [16:08] <JEEBsv> yeh [16:08] Action: Compn looks for binary codec to add to mplayer [16:08] <SvenL-> hence the need for reverse engineering ? [16:09] <Compn> yes, we need specs or reverse engineer it :) [16:09] <SvenL-> I get it, thx [16:09] <Compn> heres our r3d samples > http://samples.mplayerhq.hu/r3d/ [16:09] <JEEBsv> then there's f.ex. Earthsoft's "super special" DV format, which is their own representation of "DV" :3 [16:09] <SvenL-> question : they are generally huge files that can't be played back at full resolution [16:09] <Compn> one here too > http://samples.mplayerhq.hu/fate-suite/r3d/ [16:10] <Compn> JEEBsv : btw if you have samples of non-standard DV codecs... well i like to have them so i can add them to mplayer :) [16:10] <SvenL-> what in the decoding process handles rendering at lower resolution ? [16:10] <Compn> there is 'lowres' option, to decode at lower resolution [16:11] <Compn> i am not sure if it works with jpeg2000 codec [16:11] <JEEBsv> I used to have a sample of Earthsoft DV uploaded, I could re-upload it if it's no longer there [16:11] <SvenL-> RED, the company who develops it, provides a software that basically has a player where you can choose on the fly 1/2 res, 1/4 res etc... [16:11] <iive> wasn't lowres removed recently? [16:11] <Compn> iive : i seriously doubt it? [16:11] <JEEBsv> there's already a patch for it for ffmpeg/libav IIRC tho. Haven't gotten to reading through it yet tho [16:12] <iive> i think i've read that libav people were working on it. [16:12] <Compn> i think libav's plan is to seperate all codecs into seperate projects [16:12] <JEEBsv> I was told to take a look at the patch, pretty much IIRC [16:12] <JEEBsv> as I brought it up [16:12] <JEEBsv> I originally started checking out the specs for it, and wrote a parser for the index files [16:13] <Compn> JEEBsv : for red or dv? [16:13] <JEEBsv> earthsoft dv [16:13] <SvenL-> (background about me : I'm trying to build up a toolset for on-set footage playback, analysis, dailies exports and pre-colorgrade so I'm currently looking at what could be handled) [16:13] <JEEBsv> http://x264.fushizen.eu/encodan/earthsoft_dv/ <- also the sample is still up [16:13] <Compn> SvenL- : cool! i think its always fun when ffmpeg can do realtime movie work :) [16:14] <SvenL-> yes ! [16:14] <Compn> JEEBsv : oh, i was hoping it was dv-in-avi :P [16:14] <SvenL-> that's why i'm asking about resolution, what's my best pick for lower-res realtime playback ? [16:14] <SvenL-> hahaha [16:14] <JEEBsv> Compn: oh yes, they have their own format too :D [16:15] <JEEBsv> you don't really need the index tho [16:15] <JEEBsv> as the headers contain the same info [16:15] <Compn> SvenL- : you mean which codec is best for low-res playback ? [16:15] <Compn> good question, i dont know the answer... [16:15] <JEEBsv> http://smdn.jp/softwares/libav/pv4/ <- the patch that someone then googled up after I had already used some time to parse the 'specs' Earthsoft had on their site [16:16] <JEEBsv> (has patches for ffmpeg/libav) [16:16] <SvenL-> this may be out of my knowledge already but as I understand it, for redcode at least, there is one """codec""", a decoder only in fact [16:16] <SvenL-> Compn, I'm rather asking where I should be looking at for choosing resolution [16:16] <overflow_0f8b> Tjoppen<< neat idea :), but i have made it work lol, i just don't use a tmp variable and let gcc evaluate it [16:17] <overflow_0f8b> now _printM33("z1 x z2:", MM33( z1, z2 ) ); prints constants evaluated at compile time ^^ [16:17] <SvenL-> I mean, at what level, ffmpeg options ? player application ? even lower level ? [16:18] <SvenL-> ( http://ffmpeg-users.933282.n4.nabble.com/Cannot-decode-REDCODE-r3d-files-td… ) [16:19] <Compn> SvenL- : that ffmpeg-users post talks about old r3d files, not the newer ones. :( [16:19] <SvenL-> yes [16:19] <SvenL-> Hum... [16:20] <SvenL-> and I wonder how old/new are the samples you mentionned [16:22] <SvenL-> do you know about Cineform ? [16:22] <Compn> i know ffmpeg doesnt have a decoder for that either :) [16:23] <SvenL-> hehe, I know [16:23] <SvenL-> right now they only provide a SDK [16:27] <Compn> SvenL- : you might want to look at this project > http://code.google.com/p/ffmbc/ [16:27] <SvenL-> thank you, didn't know about it [16:27] <SvenL-> *reading* [16:31] <SvenL-> really interesting project, actually everything I need is here, awesome basically :) [16:33] <SvenL-> Compn, may I bother you just a bit more with two other quetions ? :> [16:36] <Compn> sure [16:36] <Compn> the ffmbc project is on ffmpegs' website , on the projects page. in case you want to look for other projects . of course not all projects are listed there, we need help finding them :) [16:37] <SvenL-> Okay, ffmbc is really interesting, I'll look into it. do you think it's possible to add filters ? vary basic curve filter [16:37] <SvenL-> very* [16:38] <SvenL-> (the footage from the cam is flat, just want to apply a nice S curve for convenience at editing) [16:38] <Compn> video filters? yes, ffmpeg and ffmbc use the same filter api and you can add a filter to them [16:38] <SvenL-> okay, great [16:38] <Compn> i dunno if that filter exists yet [16:39] <SvenL-> hum, I'm pretty sure it does [16:39] <Compn> i havent been paying attention :) [16:40] <SvenL-> curves is one of the most basic filter along with brightness/contrast/saturation. Oh well anyway I will just read, never used ffmpeg with advanced goals [16:41] <Compn> ah [16:41] <Compn> i have no idea what 'flat' footage means, nor what an S curve would do to it :) [16:42] <Compn> ffmpeg can also use mplayer's filters , not sure about ffmbc tho [16:42] <SvenL-> sorry, flat means that it has not much contrast at all, dark areas of the video are in fact dark grey [16:42] <Compn> oh :) [16:43] <SvenL-> that's common for current cameras, you generally tweak and get _the_ picture in post-production [16:45] <SvenL-> and an S-curve is an easy way to correct this, it bumps the contrast up so the image is "nice". It's just a quick fix so the film editor gets a nice looking video [16:46] <Compn> right, gotcha [16:49] <SvenL-> Compn, do you know what a video histogram is ? I apologize for such off-topic and basic question, /query me if you prefer [16:49] <Compn> i do, i think i've seen one in a video editor once [16:50] <Compn> dont think ffmpeg has one of those :) [16:51] <SvenL-> I've had a hard time finding out, it's what you would find in a video editor exactly [16:51] <SvenL-> it's both an analysis and effect-filter [16:53] <Mista_D> Any advice on macroblock detection? [16:53] <SvenL-> I don't know where I should ask for this, maybe in #ffmpeg first [16:57] <Compn> yes, ask user questions there [16:57] <SvenL-> yes, sorry :) [16:58] <Compn> Mista_D : sorry, no idea. try ffmpeg.org 's libav-user list or ffmpeg-user ?

[00:04] <vadim__> brontosaurusrex: in case of VOD, you have to have a bunch of ismv files one per each desired bitrate (ismv = fragmented mp4(h264+aac)) + a manifest file which contains the list of bitrates and a list of mp4 fragments [00:06] <brontosaurusrex> vadim__, yes, but the server is like an apache default or does it need anything special? [00:06] <vadim__> brontosaurusrex: the server is a web server which understand the requests from the clients and can serve the manifest and the chunks [00:06] <vadim__> for windows there is a standard solution IIS + IIS Media Services [00:07] <vadim__> brontosaurusrex: in case of Apache, I know the USP smooth streaming module for Apache [00:08] <brontosaurusrex> i see [00:08] <brontosaurusrex> thanks [00:30] <vadim__> ./creT [00:30] <vadim__> ups [00:30] <vadim__> wrong window... [00:36] <vadim__> bye all [01:08] <salsaman> hello can anybody help me with a problem decoding mpegts files ? [01:08] <burek> can you please use pastebin.com, to show your command line and its output? [01:08] <salsaman> im not using the command line [01:09] <salsaman> i have adapted the mpegts demuxer slightly [01:09] <salsaman> frames are coming out fine in the top half [01:09] <salsaman> but the bottom of the frames shows vertical lines and artifacts [01:10] <salsaman> and in the output i see e.g [mpeg2video @ 0x1f1de60] ac-tex damaged at 65 52 [01:10] <salsaman> i have checked my code very carefully so far nothing seems out of place [01:11] <salsaman> its picking the raw packets and constructing an avpakcet exactly as before as far as i can tell [01:12] <salsaman> the changes i made are very minor - basically a few changes to aviocontext, since my code does not have such sophistcated iocontext handling [01:12] <salsaman> so i am wonderin, is there somethign special i have to do for mpeg, other than feeding packets into the decoder ? [01:16] <salsaman> code is here: http://lives.svn.sourceforge.net/viewvc/lives/trunk/lives-plugins/plugins/d… [01:20] <salsaman> to test i am not even doing a seek, just playing from frame 1 onwards [01:22] <salsaman> basically lines 3613 - 3632 [01:24] <salsaman> im wondering if i should be checking the return value from avcodec_decode_video2 [01:25] <iive> salsaman: if i were you, i would have checked in i'm feeding the same packets to the decoder. [01:25] <iive> aka, not cutting the packet size. [01:26] <salsaman> i would do, but i have a hard time compiling ffmpeg from source [01:26] <iive> then maybe do some simple checksum (aka sum of all bytes). [01:26] <iive> ?? bsd? [01:26] <salsaman> so its not easy to put my debugging code in [01:26] <iive> macosx? [01:26] <salsaman> fedora 16 [01:26] <iive> windows? [01:26] <salsaman> linux [01:26] <salsaman> :-P [01:26] <iive> why would fedora have problems with ffmpeg? [01:27] <iive> the /usr/local thing? [01:27] <salsaman> i have so many versions of the libs around [01:27] <salsaman> the problem is matching the libs withe code [01:28] <iive> then build it static and don't install it. [01:28] <salsaman> yeah that might work [01:29] <iive> if it doesn't work... don't tell anybody i give you that idea :P [01:29] <salsaman> actually its not so simple [01:30] <salsaman> i can only play the file with mplayer [01:30] <salsaman> so i would have to then dig into the ,player code [01:31] <salsaman> im not sure why ffmpeg cant play it [01:31] <salsaman> i type: [01:31] <salsaman> ffmpeg canon_xha1.mpeg [01:32] <salsaman> -> File 'canon_xha1.mpeg' already exists. Overwrite ? [y/N] [01:32] <salsaman> oh wait doh [01:33] <salsaman> its ffplay, right [01:33] <iive> yep [01:34] <iive> mplayer probably uses its internal demuxer, you may try the libaformat one with -demuxer lavf [01:34] <salsaman> ok thanks [01:34] <salsaman> the other big problem i have is with h264 format [01:35] <salsaman> i have written a few demuxers that work fine, flv and asf for example [01:35] <salsaman> they work for all formats except h264 [01:36] <salsaman> is there something special that has to be done with h264 packets ? [01:42] <salsaman> for example my flv decoder works fine for vp6 [01:42] <salsaman> but for h264 it just says: [h264 @ 0xe3faa60] no frame! [01:47] <iive> no idea... sorry [01:50] <salsaman> ok thanks [02:29] <javadtalab> I have streamed a video file encoded by x264 by a server. I want to stream it (play it) at the client side by the following instruction: ffmpeg -i rtsp://192.168.1.100:8900/testStream. [02:29] <javadtalab> but I could not. I can play it with mplayer. Do I need to add some parameters to it to play stream properly? [03:03] <JDuke128> hello , i need ffmpeg java library , is there any 2012 ffmpeg java library ? all others jffmpeg , ffmpeg4j is too old [03:57] <Mista_D> Anyway to detect if macroblocks are showing in the video with ffprobe/libavfilter? [04:18] <Mista_D> what's a better gcc version for ffmpeg on Centos? requiring least patches for faac/x264/lame/xvid/... ? [05:33] <JDuke128> hello , i need ffmpeg java library , is there any 2012 ffmpeg java library ? all others jffmpeg , ffmpeg4j is too old [06:42] <grepper> fmj ? [07:00] <teratorn> JDuke128: xuggle? [13:48] <salsaman> oh if anybody is interested i solved my mpegts decoding problem [13:48] <salsaman> the answer is: [13:48] <salsaman> ctx->flags|= CODEC_FLAG_TRUNCATED [13:52] <salsaman> if anybody else has a similar problem (top half of frames looks good, bottom part is messed up), you all should advise them to set that flag bit [13:53] <salsaman> i knew it had to be something trivial [13:59] <kriegerod> I can't transcode this video to h264 using avconf/ffmpeg, must be bug. Tried git HEAD of both ffmpeg.org and libav.org. I get just grey screen, although avplay shows fine. The file: http://dl.dropbox.com/u/43104344/dump_video.flv . This is dump from wowza rtmp, using avconv/ffmpeg -vcodec copy. Please guys, if you have time, try it and advise what to do. [14:42] <smjms> does 2-pass produce better quality, or is it just for getting the right average bitrate? [14:42] <smjms> I guess I should ask in #x264 [15:07] <Mavrik> smjms, 2-pass produces usually better quality at the same bitrate as 1-pass [15:08] <Mavrik> however it does not produce better quality as -crf at same filesize [15:23] <slackyman> hi [15:24] <slackyman> it should be a good idea to let to know vpx developers that last ffmpeg version doesn't need any patch [15:26] <slackyman> bye [15:48] <meisth0th> hello [15:49] <meisth0th> ffplay continues to work even if the parametered file has reached the end, is there any parameter to tell ffmpeg to quit when file finishes to play? [15:50] <meisth0th> -autoexit k :) [16:29] <paulsf> I have a transport stream with an audio I believe to be dolby e, how would I go about extracting the dolby e out of the ts? I tried -acodec pcm_s24le, it seems to generate the wav output, however soundcode for dolby e does not recognize it as a valid dolby e stream [16:30] <paulsf> Stream #0:1[0x33]: Audio: s302m (BSSD / 0x44535342), 48000 Hz, stereo, s32, 2304 kb/s [16:31] <paulsf> this is the command line I used: ffmpeg.exe -i stream.ts -map 0:1 -acodec pcm_s24le output1.wav [16:31] <paulsf> also tried pcm_s32le to no avail [16:35] <Mavrik> paulsf, if you want to dump an audio stream out of the video [16:35] <Mavrik> you of course shouldn't recode it [16:35] <Mavrik> ffmpeg -i stream.ts -acodec copy out.dump [16:35] <Mavrik> or out.wav [16:35] <Mavrik> or w/e [16:38] <paulsf> I tried that and it says [wav @ 00000000040641E0] NONE codec not supported in WAVE format [16:38] <paulsf> Could not write header for output file #0 (incorrect codec parameters ?) [16:41] <Mavrik> paulsf, obviously dolby doesn't fit into wav container :) [16:42] <Amnesia> question.. where can I get the manpage file for ffmpeg [16:43] <paulsf> ok, but how do I get to a wav? soundcode only accepts wavs [16:43] <paulsf> soemoen suggested I use pcm_s24le, but the output is not recognized [16:43] <paulsf> someone rather [16:43] <Mavrik> Amnesia, http://ffmpeg.org/ffmpeg.html [16:43] <Amnesia> find FFmpeg-FFmpeg-1afc881 -o -iname "*gz" -o -iname "*.1" results in nothing [16:43] <Mavrik> this is pretty much the current one [16:44] <Amnesia> Mavrik: ah there's no real manpage? [16:44] <Mavrik> paulsf, pcm_s24le js a raw PCM 24-bit format, if you pass it that it'll decode your dolby to that [16:44] <Mavrik> Amnesia, it is on linux, but it has pretty much the same contents [16:44] <Amnesia> Mavrik: where can I find that file? [16:44] <Mavrik> no idea [16:44] <Amnesia> hm ok [16:44] <Mavrik> man ffmpeg usually worked for me ^^ [16:44] <Amnesia> then you installed it through your pkgmanager:) [16:46] <paulsf> ok so then how would you suggest going about it? :( [16:46] <paulsf> I just need to get it out of the ts into wav lol, so that I can import it in soundcode [16:47] <paulsf> this is what mediainfo claims to be (although I'm certain it's wrong about the 2.0 part) [16:47] <paulsf> Format : PCM [16:47] <paulsf> Muxing mode : AES3 [16:47] <paulsf> Bit rate : 2 304 Kbps [16:47] <paulsf> Bit depth : 20 bits [16:47] <paulsf> Channel(s) : 2 channels [16:48] <Amnesia> Mavrik: make documentation <- that generates it:) [16:49] <Amnesia> it seems to be outdated though [16:49] <Mavrik> Amnesia, in which parts? [16:50] <Mavrik> paulsf, hmm, no idea, obviously there's some muxing problems with dolby audio, I'm not even sure ffmpeg supports it. Sadly I don't know much about Dolby formats so I can't help you :\ [16:50] <Amnesia> videofilters [16:52] <paulsf> thanks for trying anyway, perhaps someone else will chime in :) [16:52] <paulsf> can also upload a sample if needed [16:58] <Mavrik> Amnesia, hm, video filter documentation is separate [16:58] <Mavrik> Amnesia, since it's part of libavfilter [16:58] <Amnesia> yep [16:58] <Mavrik> I usually use the online libavfilter documentation which seems up-to-date :) [16:58] <Amnesia> but the manpage still has -padtop -padbottom etc [16:59] <Mavrik> sadly, ffmpeg isn't an epitome of good documentation :( [17:03] <SvenL-> thanks for mentioning libavfilter Mavrik , I think that's what I was about to ask about [17:05] <Mista_D> Anyone can advice on macroblock detection methods? [17:07] <SvenL-> http://ffmpeg.org/libavfilter.html [17:07] <SvenL-> last line say "generated on feb. 08" [17:08] <SvenL-> I am looking for a video histogram filter, is libavfilter the right place for this ? [17:12] <saste> SvenL-: yes, an histogram filter may be placed in libavfilter [17:12] <saste> http://ffmpeg.org/pipermail/ffmpeg-devel/2010-November/098340.html [17:13] <saste> iirc the implementation was wrong (it needs to work in RGB space) [17:13] <SvenL-> hu, indeed [17:14] <SvenL-> depends on the source, actually, in my case for now I would need Y channel [17:14] <SvenL-> I've seen this while googling [17:14] <SvenL-> I'm looking for an analysing tool, not for adjustement (generally both are implemented) [17:41] <hachi> hello folks, I'm attempting to use -vcodec copy on the latest git HEAD build of ffmpeg on linux to create a video stream of mjpeg images [17:42] <hachi> when I feed a single image in and create an AVI, and then do the recipricol to pull it back out [17:42] <hachi> I end up with 3 image files, none of which are a valid image [17:43] <hachi> is anyone able to help me figure out why this is happening? [17:56] <hachi> is there a way to set the initial integer ffmpeg will use when counting a printf format filename sorta thing [18:34] <slackyman> burek: [18:35] <slackyman> are you here? [18:35] <slackyman> I sent you different emails [18:35] <slackyman> :) [18:38] <burek> slackyman, I am now :) [18:38] <burek> thanks :) [18:38] <burek> I'll take a look a little bit later, just after I grab something to eat :) [18:38] <slackyman> ok [18:39] <slackyman> :) [19:15] <slackyman> anyone here knows HOW vlc capture windows screen? [19:47] <Kingsy> burek: you around m8 ? [19:56] <slackyman> how vfwcap works? [19:59] <burek> slackyman, http://ffmpeg.test-lab.ch/viewtopic.php?f=25&t=13 [19:59] <burek> Kingsy, yes i am :) [20:00] <slackyman> burek: list: Input/output error [20:01] <Kingsy> burek: just had some thoughts about that problem I was having if you remember, I have captured my webcam from vlc (looks like about 640x480 res) it has no sound but its smoooooth as.. how can that be? going by what we found the usb wasnt capable... [20:01] <slackyman> how knows how to capture desktop in windows? [20:02] <burek> Kingsy, vlc can capture both video and audio [20:02] <slackyman> I mean, vlc uses the meta-protocolo screen:// [20:02] <Kingsy> burek: I know.. I cant get the audio to work.. [20:02] <burek> I had to use it because ffmpeg didn't resolve the bug about audio video async [20:02] <burek> that you also encountered [20:02] <burek> well [20:02] <burek> here is my cmd [20:02] <Kingsy> burek: you remember that problem we had with ffmpeg not icking up the audio? I have that too in vlc [20:02] <Kingsy> and I cant get it working [20:03] <burek> it does pick the audio [20:03] <burek> just use alsamixer to select the input device [20:03] <Kingsy> hmm not sure what you mean by that.. [20:04] <Kingsy> burek: I am in alsamixer now, I don't see any option to select the input device..

[20:06] <Kingsy> why is it using http? [20:06] <burek> it's broadcasting, not saving [20:06] <burek> but if you want to save [20:06] <burek> replace std{access=http,mux=ffmpeg{mux=flv},dst=0.0.0.0:8090/test.flv} [20:06] <burek> with [20:07] <burek> std{access=file,dst=test.flv} [20:08] <slackyman> ffmpeg -f vfwcap -i 0 avi.avi --> [vfwcap @ 01CA9A80] Could not connect to device.

[20:12] <burek> slackyman, [20:12] <burek> can you please use pastebin.com, to show your command line and its output? [20:13] <slackyman> sorry [20:51] <codepython777> When I do ffmpeg -i awesome.mp4 output.wmv -- does ffmpeg preserve the quality of the input mp4? Is there another flag I need to provide to do so? [20:52] <hi117> -vcodec copy right? [20:53] <hi117> otherwise itll reencode and lossy -> lossy = lost quality [20:57] <codepython777> hi117: Thanks. So I use ffmpeg -vcodec -i input.mp4 output.wmv? [20:57] <hi117> no [20:57] <hi117> -vcodec copy [20:58] <hi117> and put it after the -i bla.foo [20:59] <hi117> ffmpeg orders operands ffmpeg [global options] [[infile options] -i infile]... {[outfile options] outfile}... [20:59] <hi117> er... [20:59] <hi117> yes, thats right, -vcodec is an outfile option [21:07] <codepython777> will try it now. Thanks [21:07] <hi117> np [21:25] <slackyman> hi, when i cross-compile ffmpeg in mingw32 I have no dshow dev [21:44] <pythonirc101> When I try to use media player to play a wmv file created using ffmpeg, I get codec not found error. How can I fix this? [21:45] <hi117> what codec are you putting in the wmv? [21:45] <pythonirc101> WM/EncodingSettings: Lavf53.21.0 -- Is this the name of the output codec? [21:45] <pythonirc101> How can I find out which codec is it? [21:45] <hi117> ffmpeg -i file.wmv [21:46] <pythonirc101> encoder : Lavf53.21.0 [21:46] <pythonirc101> is that the codec? [21:46] <hi117> no [21:46] <hi117> its what encoded it [21:46] <pythonirc101> hi117: http://pbin.be/show/403/ [21:46] <hi117> Video: h264 (Baseline) < an example of a codec [21:47] <hi117> Stream #0:0: Video: h264 (High) < this is your codec, its h264 [21:48] <pythonirc101> hi117: any chance you know how I can make windows media player play h264? [21:48] <hi117> hehe nope [21:48] <hi117> get mplayer for windows [21:48] <hi117> thats my answer XD [21:51] <pythonirc101> hi117: I'm trying to burn DVDs from input mp4s. Windows DVD Maker is the only program I have that can do this. And it does not understand h264, hence my problem. [21:51] <hi117> it probably does [21:52] <hi117> but youre using b264 hi prifile [21:52] <hi117> profile* [21:52] <JEEB> Windows only comes with a H.264 decoder since Win7 :) [21:52] <JEEB> Which is WMP12 [21:53] <hi117> what codec would you suggest if it cant play h264? [21:53] <hi117> h263? [21:53] <pythonirc101> I don't understand. If win 7 does h264, why doesn't mine work? [21:54] <pythonirc101> windows dvd maker does not understand my container wmv files [21:54] <JEEB> put H.264 into mp4 [21:55] <JEEB> H.264 in wmv is an abomination and I don't think MS even supports that [21:55] <JEEB> or you miss the media stuff if your Win7 version is one of those SuperSpecial European ones [21:55] <hi117> ah ya wmv has problems with h264 video [21:56] <JEEB> I don't really know if it has problems per se, I just don't know how well supported that mix is :P [21:56] <JEEB> esp. with standard MS filters [21:59] <slackyman> I cannot enable dshow in my ffmpeg cross-compiled build [21:59] <slackyman> dshow doesn't appear in enabled indevs [21:59] <slackyman> after configure [22:03] <slackyman> any1 knows how? [22:04] <pythonirc101> JEEB: I've mp4s encoded in h264. What's the easiest way to keep the quality and make windows understand my files? [22:07] <slackyman> JEEB, any info about enabling dshow? [22:10] <JEEB> slackyman, no idea. But check that you have directshow headers etc. set on the machine you're cross-compiling on. [22:10] <JEEB> pythonirc101, what? [22:10] <JEEB> if you already have mp4s you should be able to load them as-is [22:11] <slackyman> JEEB i have strmif.h [22:11] <pasteeater> apparently Windows DVD Maker does not accept his H.264 in MP4, as i understand it [22:11] <slackyman> I don't know wich headers I have to have [22:11] <slackyman> :D [22:14] <slackyman> enabling avisinth doen't affect dshow, right? [22:28] <slackyman> JEEB, I've found them: they're under wine [22:28] <slackyman> but I get errors [22:38] <m4now> hello, i want to join two big mp4 files (x264,1080p) together. can ffmpeg do this without reencoding? [22:40] <m4now> the output file should be the same format. [22:44] <pasteeater> m4now: MP4Box -cat input1.mp4 -cat input2.mp4 output.mp4 [22:44] <pasteeater> results not guaranteed [22:51] <slackyman> JEEB I have dshow libs also in mingw32 directories [22:52] <slackyman> but if include them in CFLAGS and LD FLAGS I got several errors [23:04] <slackyman> anyone? [23:05] <burek> :) [23:06] <burek> is libdl linkable as a static lib in the final binary? :) [23:13] <slackyman> burek, have you tried? [23:13] <burek> well :) [23:13] <burek> I did :) I still am trying :) [23:14] <slackyman> if yuou have libdl.a in your lib path it should be loaded as static [23:15] <burek> hmh [23:17] <slackyman> as far as I know when compiling ffmpeg statically (the default) "-static" is passed as parameter to the linker [23:17] <burek> yes i know that [23:17] <slackyman> or am I wrong? [23:17] <burek> i read your mails, thanks [23:17] <burek> but [23:17] <burek> I get the same error for a lot of libs, something like this [23:17] <slackyman> have you compiled libdl or are U using the one given by repositories? [23:18] <burek> /usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/4.4.5/../../../../lib/libasound.a(dlmisc.o): in function snd_dlopen:dlmisc.c:70: error: undefined reference to 'dlopen' [23:18] <slackyman> as I wrote in my emails you have to check EVERY lib configure options [23:18] <burek> and I read about libdl that it's a part of gcc I guess [23:18] <burek> which (tell me I'm wrong) means I have to compile my own gcc? :S [23:18] <burek> I did [23:18] <slackyman> no [23:18] <burek> except libdl [23:19] <slackyman> dlopen [23:19] <slackyman> uhm... [23:19] <burek> where is the homepage of that stuff anyway [23:19] <burek> to download the source [23:20] <slackyman> I think it comes from glibc [23:20] <burek> so, I need to compile glibc statically [23:20] <burek> and just continue with ffmpeg the usual way? [23:20] <slackyman> try :D [23:20] <burek> :D [23:20] <burek> I think I'll be sorry, I had that kind of feeling :D [23:21] <slackyman> no, I think everything will go fine [23:21] <Mista_D> How do I see histogram with -qphist? [23:22] <slackyman> wait a moment, burek [23:22] <burek> http://linuxsoft.cern.ch/cern/slc6X/x86_64/yum/updates/repoview/glibc-stati… [23:22] <burek> hmh, there are obviously libs built in a static way [23:22] <burek> so I guess I won't break anything :D [23:22] <slackyman> wait [23:22] <burek> ok [23:23] <slackyman> dlopen should be difened in libdl.c [23:24] <slackyman> uhm... [23:24] <burek> I'll just git clone glibc.git and try [23:24] <slackyman> I think that using a glib static build could be better [23:26] <burek> Mista_D, Google didn't help much..? :S [23:27] <Mista_D> burek: nope. [23:28] <burek> I can see :/ not much help there :/ you can try in #ffmpeg-devel though [23:29] <burek> if they don't know, you're out of luck [00:00] --- Fri Feb 10 2012

[01:13] <Daemon404> Compn, just an fyi: BBB is being payed by google to write a perl wrapper for msvc for libav [01:13] <Daemon404> re: that ML thread [01:19] <Compn> Daemon404 : people compile ffmpeg with msvc all the time ... you mean for default compilation ? [01:19] <Daemon404> um [01:19] <Daemon404> thats kind of impossible. [01:20] <Daemon404> every single file uses at the very least, named struct initialization [01:20] <Daemon404> with msvc does not support.

[01:51] <icat> (sry, copy paste) [01:51] <icat> i use ffmpeg -loop 1 -shortest -y -i "$poster" -i "$mp3" -acodec copy "$outfile" [01:51] <icat> but after a while, the picture gets artificats [01:51] <icat> and way to solve that? [01:52] <sacarasc> Use a better codec! [01:54] <icat> this uses mpeg4 [01:54] <icat> but it seems that even if I set -v:b, -minarete and -maxrate, the bitrate goes down eventually [01:54] <icat> after like 20 seconds [01:56] <icat> i can't seem to force it to CBR, or to constant quality [01:56] <icat> and it's a goddamn still jpeg [02:12] <Ginks> tdr, yah, there's one before scale and after [out], unless I'm missing one [02:13] <tdr> Ginks i dont know watermark syntax, but usually after -f the next arguement is filename, so wondering if it is order that's the problem [02:45] <sacrelege> Hi all, I get a "-22" error code back from av_open_input_file(). Where can I lookup the error codes? [03:15] <darkstarbyte> Can the mpeg2 encoder handle multiple threads? [05:23] <Ginks> ffmpeg -i hot.flv -an -vf "scale=-1:720,movie=/srv/www/vhosts/testing.com/htdocs/data/watermark.png [watermark]; [in][watermark] overlay=10:10 [out]" -f mp4 scaled.mp4 [05:23] <Ginks> I run that, and I get: [05:23] <Ginks> Too many inputs specified for the "movie" filter. [05:26] <relaxed> Ginks: pastebin.com the command and all output [05:40] <Ginks> relaxed, k [05:41] <Ginks> http://pastebin.com/SukHg8bx [05:41] <Ginks> done [05:43] <Ginks> http://pastebin.com/UuZERKEe [05:43] <Ginks> I think that's more of the way it should be actually [05:43] <Ginks> I want it to scale prior to watermarking [05:43] <Ginks> err, doing the overlay [05:49] <relaxed> "[in]scale=-1:720[video];movie=/srv/www/vhosts/testing.com/htdocs/data/waterm… [wm];[video][wm] overlay=main_w-overlay_w-10:10 [out]" [05:50] <relaxed> change it back to overlay=10:10 if that's what you want [05:53] <Ginks> hrmm [05:54] <Ginks> so that's all you do is start with [in], place a command naming it afterwards, seperate them with ; and then put them in the order you want them to run? [05:54] <Ginks> why isn't overlay just included after movie then? [05:54] <Ginks> since it's basically part of that [05:56] <Ginks> what you gave me appears to be doing the trick [05:56] <relaxed> is you watermark not added? [05:56] <relaxed> your* [05:56] <Ginks> just waiting for it to finish running [05:56] <relaxed> oh, ok [05:57] <relaxed> Ginks: Did you read this? http://ffmpeg.org/libavfilter.html#Introduction [05:59] <Ginks> relaxed, yes, but it all seems foreign to me [05:59] <Ginks> I'm not quite sure the syntax [05:59] <Ginks> even after reading it [06:01] <Ginks> -qscale 1 would that be a good idea to add? [06:01] <Ginks> I'd like the highest quality from the conversion [06:02] <relaxed> what video codec do you need? what is this for? [06:02] <Ginks> it's for web [06:03] <Ginks> niche tube site [06:03] <Ginks> using x264 [06:03] <Ginks> for the final output mp4 [06:03] <Ginks> if I'm saying that right [06:04] <Ginks> the conversion server is a dual quad-core xeon with 24gb ram [06:04] <Ginks> and it won't be processing many videos each day [06:04] <Ginks> so it can sit and crunch on one for hours [06:04] <relaxed> -c:v libx264 -threads 0 -preset veryslow -crf 18 [06:05] <relaxed> lower the crf vaule for better quality [06:05] <Ginks> ok, I'll give that some testing [06:05] <Ginks> thanks a lot [06:05] <relaxed> you're welcome [06:20] <Ginks> relaxed, [06:20] <Ginks> cbr, that's constant bitrate [06:20] <Ginks> is that really needed in pseudostreaming? [06:21] <Ginks> my original setup was 2 pass x264 [06:32] <relaxed> yes, an average bitrate is probably better for streaming [07:25] <Ginks> relaxed, [07:26] <Ginks> is it possible to create some type of animated watermark? [07:50] <relaxed> Ginks: I believe you can overlay another video ontop of the video, so yes [08:06] <Ginks> relaxed, any ideas where I might start? [08:16] <relaxed> Ginks: it would be the same as overlaying a png [08:20] <Ginks> relaxed, what format should I attempt it with though? [08:20] <Ginks> gif is horrible [08:20] <Ginks> apng maybe? [08:29] <relaxed> maybe a series of images? like %03d.png ? [08:30] <Ginks> good idea [09:12] <Ginks> relaxed, but what would regulate how the watermark would play? [09:12] <Ginks> would I create the watermark with the output fps in mind [09:14] <Ginks> I'm going to do a bit of testing [10:01] <Ginks> relaxed, it appears that %0d.png works, but the png transparancy doesn't remain [10:01] <Ginks> becomes white [10:01] <Ginks> and the last png remains the watermark once it's out of frames [10:13] <lorenzosu> Hi. How can I do -sameq in avconv? -qn? [10:13] <lorenzosu> sorry I mean -qscale [11:36] <slackyman> Hi [11:36] <slackyman> I need a help [11:36] <slackyman> :) [11:36] <Mavrik> good for yuo. [11:36] <slackyman> eh eh [11:37] <slackyman> i'd like to give a icon to ffmpeg win version but I don't know how [11:37] <slackyman> or, maybe [11:37] <slackyman> I can use ResHack but then I violate GPL [11:37] <slackyman> since the source will not give exactly the binary I want to redistribute [11:38] <JEEB> can't you use an resource (rc) file or something? [11:38] <slackyman> yes, ResHack is a Resource editor [11:38] <JEEB> I mean on the source side [11:39] <slackyman> I'm not so good as C programmer :) [11:39] <slackyman> maybe google can help [11:39] <slackyman> :P [11:39] <Mavrik> slackmagic, http://stackoverflow.com/a/708382/169115 [11:40] <JEEB> yup, there's plenty of stuff on the internet about it in general :) [11:40] <JEEB> x264 lately added resources as well, http://git.videolan.org/gitweb.cgi?p=x264.git;a=commit;h=a2925c5a707e833c34… [11:40] <JEEB> (without an icon, but that's not exactly a big part of it all) [11:40] <slackyman> Mavrik: I was just THERE! :) [11:41] <slackyman> GREAT! [11:41] <slackyman> thanks [11:47] <slackyman> A little question [11:47] <slackyman> in the git repo the code is up-to-date to CVE-fixes as in the 0.10 release? [11:48] <JEEB> you can say so that the repo is branched off from time to time to create releases [11:48] <JEEB> thus, the git repo's HEAD [11:48] <JEEB> (of the master branch) [11:48] <JEEB> is always either the same as a release, or newer than it [11:49] <slackyman> thanks [11:50] <slackyman> the work of the ffmpeg staff is huge... O.o [13:07] <slackyman> JEEB are you still here? [13:09] <JEEB> wat [13:10] <slackyman> I'm trying to add ffmpegres.o to ffmpeg.o buti I cannot find the file in wich the binary is compiled :P [13:11] <slackyman> i want to add resfile *.o to ffmpeg [13:12] <JEEB> > in which the binary is compiled [13:12] <JEEB> do you mean the file containing build instructions? [13:12] <JEEB> if so, see Makefile [13:12] <slackyman> ok, thanks [16:07] <salsaman> hi [16:07] <salsaman> i wrote a demuxer to play hdv files, its working more or less [16:08] <salsaman> the upper part of the frames shows up fine, but the lower part is messed up and i see [16:08] <salsaman> e.g. [16:08] <salsaman> [mpeg2video @ 0x3148420] ac-tex damaged at 66 43 [16:08] <Milos_SD> Hi guys, is there any known bug in ffmpeg with mpd? Please check this out: http://tinypaste.com/7ecf2b83 [16:08] <Milos_SD> my mpd doesn't add all my music to database [16:09] <Milos_SD> I was told on #mpd channel that it is ffmpeg bug [16:09] <salsaman> occasionally also i see e.g. [mpeg2video @ 0x3148420] invalid mb type in I Frame at 77 57 [16:10] <salsaman> the thing is, the got_picture flag is being set [16:41] <jl> can ffmpeg change fps on a mpeg2 video without re-encoding? -r has no effect without a codec or I am doing something wrong. [16:42] <Milos_SD> Hello [16:42] <Milos_SD> What does this mean in line 29: http://pastebin.com/n8TXMCM3 ? [16:47] <tdr> Milos_SD, did you build your ffmpeg and mpd or get them from bins? [16:47] <Milos_SD> I built them [16:48] <Milos_SD> from latest git :) [16:54] <Milos_SD> tdr, any ideas? :) [16:55] <tdr> Milos_SD, its something in the linking of your ffmpeg i'd say [16:56] <tdr> 228: 000000000000e230 153 FUNC GLOBAL DEFAULT 12 av_realloc_f@@LIBAVUTIL_51 is what i get from readelf -a /usr/lib64/libavutil.so.51.34.101 |grep symbol av_realloc_f, what do you get? [16:57] <Mavrik> Milos_SD, do you have statically linked ffmpeg? [16:57] <tdr> yeah, thats what i was thinking it might be [16:57] <Mavrik> mhm [16:58] <Milos_SD> this: readelf -a /usr/lib/libavutil.so.51.38.100 |grep symbol av_realloc_f gives me this: grep: av_realloc_f: No such file or directory [16:58] <Milos_SD> :S [16:58] <Milos_SD> Mavrik, no it is not, I have --enable-shared in ./configure options :) [16:58] <tdr> Milos_SD different vesion of the lib [16:58] <Mavrik> even if you do "whereis ffmpeg" and then "ldd <path to ffmpeg>"? [16:59] <tdr> oh you did change it [16:59] <tdr> Milos_SD, take out the word symbol [16:59] <tdr> look for av_realloc_f [17:00] <Milos_SD> 156: 000000000000b2ca 107 FUNC GLOBAL DEFAULT 12 av_realloc_f@@LIBAVUTIL_51 [17:00] <Milos_SD> and the one Mavrik asked: http://pastebin.com/1tTuL68F [17:02] <Mavrik> huh [17:03] <Mavrik> that seems like broken compile of ffmpeg and broken mpd linkage :\ [17:03] <Milos_SD> btw, I am getting this when I do: ffmpeg --version : http://pastebin.com/RMU19vAF [17:04] <Milos_SD> don't know why am I getting that warrnings about library missmatch ... I started getting it when I upgraded to Ubuntu 12.04 Alpha ... [17:04] <Milos_SD> "S [17:04] <Milos_SD> :S [17:05] <Milos_SD> configuration missmatch* [17:22] <JyZyXEL> is it possible to have a DV video stream in a .mpg? [17:25] <Mavrik> Milos_SD, obvously you have different ffmpeg for different library versions [17:25] <Mavrik> Milos_SD, I suggest you use the ubuntu guide in topic to compile the 0.10 version and replace the broken repository installed one [17:38] <salsaman> no mpeg expets here then ? [17:42] <JyZyXEL> guess not :p [17:42] <JyZyXEL> im gonna play the waiting game [17:45] <Milos_SD> Mavrik, "fixed" it by deleting ffmpeg lib files from /usr/lib/x86_64-linux-gnu/ [17:46] <Milos_SD> I had to do that, because there is no way to uninstall ffmpeg lib packages [17:48] <salsaman> JyZyXEL, I have never seen dv in an mpeg container [17:49] <JyZyXEL> i wonder if its possible [17:49] <salsaman> doubtful [17:49] <salsaman> dv uses a kind of jpeg encoding [17:50] <salsaman> fixed frame size [17:51] <JyZyXEL> i have this .mpg file made by a file recovery (carver) software, apparently it has a mpeg header yet ffmpeg detects a dv video stream in it [17:52] <salsaman> but can you play it ? [17:52] <JyZyXEL> well theres 1 frame of video and rest is just funky looking squares :p [17:54] <JyZyXEL> and the one video file was found as 11 differnt .mpg files for some reason :P [17:55] <JyZyXEL> i can get 1 frame of actual picture from each one :p [17:57] <JyZyXEL> but looking at the recovery software it has: static const unsigned char mpg_header[3]= {0x00, 0x00, 0x01}; [17:58] <JyZyXEL> so it might just be it recovered from the middle of a DV file thinking it was .mpg [18:00] <JyZyXEL> but then i wonder does ffmpeg have the capability to detect its DV even if theres no DV header [18:03] <salsaman> dv doesnt really have much of a header [18:03] <salsaman> frame size and fps are fixed [18:04] <JyZyXEL> well if it was in a DV-AVI then it'd have the RIFF header [18:04] <salsaman> yes you can have dv inside avi [18:06] <JyZyXEL> is there even a .dv format where you just have DV data? [18:07] <salsaman> yes there is a raw dv format [18:07] <JyZyXEL> maybe thats what i have and it just happens to start with 0x0, 0x0, 0x1 [18:08] <salsaman> maybe [18:08] <salsaman> or maybe that was partway through a frame [18:09] <JyZyXEL> well it certainly doesn't play on any player :p [18:09] <salsaman> it should happen by chance roughly every 16MB or so [18:12] <JyZyXEL> well trying to convert 300MB of that with ffmpeg gets me only a really short video, one clear frame and few noise ones [18:15] <JyZyXEL> i wonder what it takes for ffmpeg to claim a certain file is dvvideo [18:17] <JyZyXEL> and MediaInfo tool also claimed its DV and even got the Recorded date from it [18:17] <JyZyXEL> DV (DVCPRO) it says [18:19] <JyZyXEL> so im guessing its raw DV data [18:19] <JyZyXEL> and it must be starting from a random position [18:22] <JyZyXEL> yup, deleting bytes from the start of the file doesn't change how it detects [18:23] <JyZyXEL> this is fun, everytime i delete a byte it plays differently :D [18:24] <JyZyXEL> eventually i should get to a point where it starts from a correct position like a start of frame? :p [20:03] <kriegerod> is setting format time_base still responsibility of API user? I mean to set e.g. 1k for flv, 90k for mpegts. Is there any automatic correct setting in some API call? [20:34] <Kingsy> someone around? I am trying to capture audio / video with this command --> fmpeg -f video4linux2 -s 320x240 -i /dev/video0 -f alsa -i default -f mp4 Filename.mp4 <-- it works GREAT apart from there is no audio .. what am I doing wrong? [20:36] <john_doe_jr> how do you use ffmpeg to record sound from a sound card? [20:36] <indigo> hi [20:37] <burek> john_doe_jr, [20:37] <indigo> I want to add a resource file to ffmpeg.exe with windres [20:37] <burek> did you try ffmpeg -i /dev/snd/whatever out.wav [20:37] <indigo> I'm cross-compiling [20:37] <burek> indigo [20:38] <indigo> wait, wait [20:38] <Kingsy> burek: any idea about my problem? :) [20:38] <burek> Kingsy [20:38] <slackyman> sorry [20:38] <burek> can you please use pastebin.com, to show your command line and its output? [20:38] <slackyman> it was a ghost [20:38] <john_doe_jr> burek, what's up/ [20:38] <slackyman> indigo was.. me [20:38] <john_doe_jr> ? [20:39] <burek> :) [20:39] <slackyman> I cannot use a resource editor [20:39] <Kingsy> burek: see, I think thats the problem.. how do I find out where my audio device lives in /dev/ ? [20:39] <burek> john_doe_jr, did you try that command above [20:39] <slackyman> since I want to redistribute the file [20:39] <slackyman> so the GPL license have to be honored [20:39] <burek> Kingsy, did you try lspci [20:40] <slackyman> and the source code MUST generate the same binary [20:40] <Kingsy> burek: is it the soundcard I want? I assumed the audio was onboard the webcam? [20:40] <burek> oh wait, Kingsy, do you have alsa installed or oss [20:40] <burek> and did you compile your ffmpeg or used from repos [20:40] <Kingsy> burek: I got it from the repos [20:41] <burek> slackyman, why do you want to add resource to exe? [20:41] <john_doe_jr> burek, well, I see a number of devices at /dev/snd/ ...which one do I choose? [20:41] <Kingsy> burek: and I am not sure what I have installed as far as alsa etc goes.. [20:41] <burek> Kingsy, can you type ffmpeg -version and give us the pastebin [20:41] <Kingsy> sure [20:41] <burek> john_doe_jr, can you also do ffmpeg -version [20:41] <burek> and give us the pastebin [20:41] <Kingsy> burek: http://pastie.org/3343385 [20:42] <john_doe_jr> burek, ffmpeg version N-36000-g154c0a8 [20:42] <burek> john_doe_jr, [20:42] <burek> can you please use pastebin.com, to show your command line and its output? [20:42] <slackyman> burek, I want to give an icon and extra info to the *.exe file [20:42] <slackyman> john_doe_jr: maybe you can use fuser to find where your soundcard is located [20:42] <burek> Kingsy, your ffmpeg is not compiled to support alsa, so you need to try with oss [20:42] <burek> just a second [20:43] <Kingsy> burek: np [20:43] <john_doe_jr> burek, http://pastebin.com/XkEHfQtJ [20:43] <burek> Kingsy, try this: ffmpeg -f oss -i /dev/dsp out.wav [20:43] <Kingsy> ok 1 sec [20:43] <john_doe_jr> slackyman, well, I have by-path controlC0 midiC0D0 pcmC0D0c pcmC0D0p pcmC0D1p seq timer when I do a cd /dev/snd/ [20:43] <Amnesia> hm is there anyway to hardcode srt files when converting an avi to mpeg2 ? [20:43] <Kingsy> burek: [oss @ 0x15a2340] /dev/dsp: No such file or directory [20:44] <slackyman> fuser -v /dev/snd/* [20:45] <john_doe_jr> slackyman, http://pastebin.com/iX0F2ycR [20:45] <Amnesia> anyone? [20:46] <burek> just a second [20:47] <john_doe_jr> slackyman, which one do I use? [20:47] <burek> Kingsy, did you install alsa/oss? does your sound card work? [20:47] <burek> slackyman, why not edit the source to modify the resulting resource? [20:47] <Kingsy> burek: yeah my soundcard works [20:48] <burek> john_doe_jr, did you try that too? [20:48] <slackyman> john_doe_jr: wait [20:48] <Kingsy> I don't remember installing alsa.. umm 1 sec I will check what vlc is using [20:48] <burek> ffmpeg -f oss -i /dev/dsp out.wav [20:48] <Kingsy> ok 1 sec [20:48] <Kingsy> what is /dev/dsp? [20:49] <Kingsy> burek: vlc uses the ouput module "default" [20:49] <burek> Amnesia, do you need subtitles on video? [20:49] <burek> burned in video? [20:49] <Amnesia> burek: yep [20:49] <Amnesia> tried -newsubtitle but that didnt do the job [20:51] <john_doe_jr> slackyman, burek which do I use? [20:51] <burek> newsub.. is for adding a new subs stream [20:51] <burek> for example for dvd or something [20:51] <burek> that's not what you need [20:51] <Amnesia> I see [20:52] <Amnesia> is it supported at all? [20:52] <burek> you need to use libass [20:52] <slackyman> john_doe_jr: try alsa or oss [20:52] <burek> http://ffmpeg.org/ffmpeg.html#ass [20:52] <burek> something like: ffmpeg -i ... -vf "ass=titles.ass" ... out.avi [20:52] <Amnesia> hm [20:53] <Amnesia> guess it wont swallow srt files [20:53] <burek> john_doe_jr, try typing: arecord -l [20:53] <burek> Kingsy, you too [20:53] <burek> Amnesia, no [20:53] <burek> only .ass [20:53] <Amnesia> hm [20:53] <burek> find a converter [20:53] <Amnesia> yeh [20:53] <john_doe_jr> burek, http://pastebin.com/iwz8R6Fa [20:54] <Freakshow> can I haz aligned IDR's with ffmpeg? [20:55] <Kingsy> burek: http://pastie.org/3343464 [20:55] <burek> john_doe_jr, and Kingsy, try ffmpeg -f alsa -i hw:0 out.wav [20:55] <slackyman> yep, burek [20:56] <burek> does it work [20:56] <Kingsy> burek: that captures to a file, but the file contains no audio [20:56] <Kingsy> i.e no errors.. but no audio in the file [20:57] <john_doe_jr> burek, 'ffmpeg -f alsa -i hw:0 out.wav' results in Unknown input format: 'alsa' [20:57] <burek> Kingsy, you have multiple record cards [20:57] <burek> probably usb camera [20:57] <Amnesia> hm so far I can't find a conversion file:) [20:57] <burek> and integrated audio card [20:57] <Amnesia> btw, what's the main difference between mencoder and ffmpeg? [20:57] <burek> try with -i hw:1 instead [20:58] <Kingsy> burek: when I change it to that. it says --> [alsa @ 0x1b75340] cannot set channel count to 2 (Invalid argument) [20:58] <john_doe_jr> burek, same problem [20:59] <brontosaurusrex> how would one do some motion blur when going from 100fps to 25fps? [21:00] <burek> Kingsy, [21:00] <burek> try ffmpeg -f alsa -ac 1 -i hw:1 ... [21:00] <burek> john_doe_jr, u2 [21:01] <burek> brontosaurusrex, did you try any of the ffmpeg's video filters? [21:01] <shellox> hi [21:01] <Amnesia> ugh [21:01] <burek> http://ffmpeg.org/ffmpeg.html#Video-Filters [21:01] <Amnesia> I'll aks my entire question.. [21:01] <Amnesia> I've got an avi file, thats 4:3 with no subs [21:01] <brontosaurusrex> burek, a different combos of interlace and yadif and they are fail [21:01] <brontosaurusrex> tinterlace* [21:01] <Kingsy> burek: that worked!! but the volume is pretty low on it, I don't suppose that can be adjusted in the settings? [21:02] <Amnesia> I'd like to convert this to 16:9 (so widescreen, with black parts on the bottom and top) and add subtitles [21:02] <Amnesia> what's my best bet.. [21:02] <Amnesia> ? [21:02] <john_doe_jr> burek, unkown input format 'alsa' [21:02] <slackyman> Kingsy: try alsamixer [21:02] <shellox> i need your help guys. I try to convert a avi video to mpeg2 ts or mpeg, so that it can be played on this tv from usb stick http://www.amazon.com/Sony-BRAVIA-500-32-Inch-Black/dp/B0035ER1HS [21:03] <burek> Kingsy, try alsamixer [21:03] <burek> then use <tab> to switch to recording device [21:03] <burek> s [21:03] <burek> or use F6 to switch to usb device [21:03] <burek> and again <tab> to move from playback/recording [21:03] <shellox> it's a european tv, so the target must be pal-dvd ? [21:03] <Kingsy> burek: so apt-get install alsamixer and its something you setup seperate? [21:03] <Amnesia> shellox: most tvs nowadays do ntsc,pal [21:03] <burek> john_doe_jr, your ffmpeg is not compiled with alsa support, you'll need to try with -f oss -i /dev/dsp [21:03] <Amnesia> not sure about secam [21:04] <shellox> Amnesia: you have an idea how to convert it? [21:04] <burek> Kingsy, apt-get install alsa-utils [21:04] <Amnesia> shellox: nope sorry, also having an issue atm myself [21:04] <shellox> here is the result of my first attempt: http://dpaste.com/699802/ [21:05] <burek> Amnesia, http://ffmpeg.org/ffmpeg.html#toc-Video-Filters [21:05] <Amnesia> should be fine afaik [21:05] <Amnesia> burek: Video filters? [21:05] <burek> you probably need pad [21:05] <Kingsy> burek: it says its already installed [21:05] <burek> or scale if you want to stretch [21:05] <burek> Kingsy, then just type alsamixer [21:05] <Amnesia> burek: yep.. [21:06] <Amnesia> but what about the subs, since I can;t find anything to convert a srt to ass [21:06] <shellox> is ac3 ok for tv's? [21:06] <Amnesia> shellox: depends on the tv [21:06] <burek> Amnesia, im searching for a converter, be patient [21:06] <Amnesia> ah thanks [21:06] <Amnesia> sorry for whining [21:06] <john_doe_jr> burek, ffmpeg -f oss -i /dev/dsp out.wav is producing a output.wav file but it is not recording the sound [21:06] <Kingsy> burek: thanks.. :) [21:06] <Kingsy> awesome!!! [21:07] <burek> Amnesia, https://github.com/morr/srt2ass [21:07] <burek> Kingsy, :beer: :) [21:08] <burek> john_doe_jr, I'm not that familiar with oss [21:08] <Amnesia> burek: first link.. [21:08] <Amnesia> shame on me [21:08] <Amnesia> thanks [21:08] <Kingsy> burek: for sure!! [21:08] <Amnesia> ruby <3 [21:08] <burek> Amnesia, :beer: [21:08] <Kingsy> burek++ [21:08] <burek> ^^ [21:08] <Amnesia> perhaps something stronger:)? [21:08] <burek> john_doe_jr, is there any chance you can compile your ffmpeg [21:08] <burek> you'd need just to apt-get install libasound2-dev [21:08] <burek> and compile ffmpeg [21:08] <john_doe_jr> burek, sure...how do I compile it with alsa support? [21:08] <burek> for that to work [21:08] <Amnesia> what's basically the difference between mencoder and ffmpeg? [21:08] <Amnesia> they do the same right:)? [21:09] <burek> I can't tell, I didn't use mencoder that much [21:09] <Amnesia> hm ok:) [21:09] <burek> btw john_doe_jr when you do ./configure [21:09] <burek> make sure that the last lines of output say something like "outdevs: alsa" [21:10] <john_doe_jr> burek, how do I remove my current version of ffmpeg? [21:10] <burek> john_doe_jr, did you install from repos or compiled [21:10] <john_doe_jr> burek, git clone [21:10] <burek> make uninstall [21:10] <burek> make distclean [21:10] <burek> git pull [21:10] <burek> ./configure .. [21:11] <john_doe_jr> burek, what should be my ./configure options? [21:12] <burek> john_doe_jr, it depends, what do you need your ffmpeg to do? [21:12] <john_doe_jr> burek, I need to produce mp4s after recording from my sound card [21:12] <burek> i guess you'll need h264 too [21:12] <Kingsy> burek: actually.. not so good.. [21:12] <Kingsy> :S the sound is out of sync [21:13] <burek> Kingsy, try -async 1 before -i [21:13] <Kingsy> ok 1 sec [21:13] <burek> john_doe_jr, for the first run, try just ./configure [21:13] <john_doe_jr> burek, got a whole bunch of stuff [21:14] <Kingsy> burek: nope its still out [21:14] <burek> Kingsy, [21:14] <burek> can you please use pastebin.com, to show your command line and its output? [21:15] <burek> john_doe_jr, name them all [21:15] <Kingsy> burek: sure [21:15] <burek> use pastebin [21:16] <Kingsy> burek: http://pastie.org/3343603 <-- that is the command at the top, what it says up until capture.. then I just crashed out of it [21:16] <john_doe_jr> burek, http://pastebin.com/qaYEUPBk [21:16] <burek> john_doe_jr, no alsa [21:16] <burek> in outdevs [21:16] <burek> did you do [21:16] <burek> apt-get install libasound2-dev [21:17] <john_doe_jr> alright I just install libasound2-dev [21:17] <john_doe_jr> does that ./configure have support for mp4s? [21:18] <burek> type ./configure --help | less [21:18] <john_doe_jr> burek, alright [21:18] <burek> Kingsy, try to remove -f mp4 [21:19] <burek> and output to test.avi [21:19] <burek> see if there is still async [21:19] <Kingsy> ok [21:19] <burek> also remove -async 1 [21:19] <john_doe_jr> burek, I got to download git clone git://git.videolan.org/x264.git [21:21] <vadim__> hi2all [21:21] <Kingsy> burek: thats even more out of sync that it was [21:22] <burek> Kingsy, im afraid you'll end up here: http://ffmpeg.org/trac/ffmpeg/ticket/692 [21:22] <burek> try posting a message [21:22] <burek> because it will make things progress as more people report it as a problem [21:22] <burek> john_doe_jr, even better :) [21:23] <Kingsy> argh.. seriously? a bug.. so thats it then no fix :S [21:23] <john_doe_jr> burek, how do I do a ./configure with alsa support? [21:23] <burek> im afraid so [21:23] <burek> the bug was reported long ago [21:23] <burek> so i doubt it will be fixed soon [21:23] <burek> try playing with -async [21:23] <Kingsy> hahah even worse.. well thats just a scrapper then :) [21:23] <Kingsy> burek: ok :S [21:23] <burek> http://ffmpeg.org/ffmpeg.html [21:23] <burek> :S [21:24] <burek> john_doe_jr, you don't it's autodetected :) [21:24] <Kingsy> burek: you have been very helpful tho.. even if I do have to scrap ffmoeg.. thanks [21:24] <burek> :beer: :) [21:24] <john_doe_jr> burek, this is my ./configure now: http://pastebin.com/H0s2N8Bn [21:24] <vadim__> how can I start ffmpeg in background (linux)? & at the end of the command does not work for ffmpeg 0.9.1, at least for me... [21:24] <john_doe_jr> burek, do you see alsa somewhere? [21:26] <Kingsy> burek: messing with async does nothing I am afriad [21:26] <john_doe_jr> burek, yup, I see enabled outdevs now: alsa oss [21:26] <john_doe_jr> burek, alright, so now I'm going to do the following: ./configure --enable-static --enable-shared --disable-asm [21:27] <john_doe_jr> burek, sorry...I meant ./configure --enable-gpl --enable-nonfree --enable-libx264 [21:27] <burek> john_doe_jr, its ok now [21:27] <burek> you see last line [21:28] <burek> enabled outdevs [21:28] <john_doe_jr> burek, yup, noticed that [21:28] <burek> Kingsy, try listing -i <audio> before -i <video> [21:28] <burek> dont disable asm [21:28] <burek> it will slow your ffmpeg down [21:28] <Kingsy> what is asm? [21:28] <burek> assembler [21:28] <Kingsy> or was that for someone else? [21:29] <burek> for john_doe_jr :) [21:29] <john_doe_jr> burek, too late... [21:29] <burek> john_doe_jr, ctrl+c [21:29] <burek> make distclean [21:29] <burek> :) [21:29] <burek> ./configure --enable-gpl --enable-nonfree --enable-libx264 <- that's ok [21:29] <burek> but why enable-nonfree? [21:30] <john_doe_jr> burek, I don't know what enable-nonfree means...I just copied it from a web site post [21:30] <john_doe_jr> what does --enable-nonfree mean anyways? [21:30] <Kingsy> burek: still the same fault [21:31] <burek> ./configure --help | grep nonfree [21:31] <burek> Kingsy, :S [21:31] <john_doe_jr> burek, it's running now ... [21:32] <Kingsy> burek: nm thanks anywyas [21:32] <burek> Kingsy, try using vlc.. [21:32] <burek> until the bug is fixed [21:32] <john_doe_jr> burek, it takes forever to compile ffmpeg [21:33] <burek> john_doe_jr, it takes 10 minutes on modern machines [21:33] <vadim__> --enable-nonfree (libfaac and libfaad have non-free licenses) [21:33] <john_doe_jr> burek, yup forever [21:33] <burek> :) [21:33] <burek> you're young :) [21:33] <burek> you'll live :) [21:34] <john_doe_jr> burek, alright finally I'm done [21:34] <burek> already? :) [21:34] <john_doe_jr> burek, I have a really fast machine [21:34] <burek> ok [21:35] <burek> try now ffmpeg -f alsa -i hw:0 out.wav [21:35] <slackyman> Amnesia: I found that ffmpeg can convert srt to ass [21:35] <Amnesia> :O [21:35] <Amnesia> tell me:) [21:35] <burek> really? [21:35] <burek> cool :D [21:35] <slackyman> ffmpeg -i file.srt file.ass [21:35] <burek> lol :D [21:35] <slackyman> really [21:35] <burek> nice :D [21:35] <slackyman> just tried! [21:35] <Amnesia> neat:) [21:35] <burek> lol2 :D [21:36] <slackyman> awfully great! >.< [21:36] <burek> +1 [21:36] <Amnesia> thanks for the info^^ [21:36] <john_doe_jr> burek, did not give any errors but did not record the sound [21:36] <slackyman> I seriously think that ffmpeg is the best audio-video swissknife! [21:36] <burek> john_doe_jr, arecord -l [21:36] <burek> (small L) [21:37] <john_doe_jr> burek, arecord -l [21:37] <john_doe_jr> **** List of CAPTURE Hardware Devices **** [21:37] <john_doe_jr> card 0: AudioPCI [Ensoniq AudioPCI], device 0: ES1371/1 [ES1371 DAC2/ADC] [21:37] <john_doe_jr> Subdevices: 1/1 [21:37] <john_doe_jr> Subdevice #0: subdevice #0 [21:37] <burek> slackyman, join the club :) [21:37] <Kingsy> burek: just curious, if I was doing video only, how come I cant increase the resolution without it going blocking and jumpy? its an hd cam so it supports a high smooth resolution [21:37] <burek> john_doe_jr, alsamixer, press <tab>, turn up the volume for the recording device [21:37] <burek> and try again [21:37] <slackyman> burek: I'm involved in a personal project, re-write entirely WinFF [21:37] <burek> Kingsy, you need to set the resolution before -u [21:37] <burek> -i [21:38] <slackyman> with best gui [21:38] <burek> for ex. ffmpeg -s 1080x720 -i <video> [21:38] <burek> will capture the video at that resolution [21:38] <burek> for ex. ffmpeg -i <video> -s 1080x720 [21:38] <burek> that will capture video at some default (unknown) resolution [21:38] <burek> and rescale video [21:38] <john_doe_jr> alsamixer shows that 'master' is the default and pressing tab shows that the 'capture' is up 100% [21:38] <burek> which will end up being not what you want [21:39] <burek> the order of params does matter [21:39] <burek> john_doe_jr, well is it a microphone? [21:39] <burek> what's your recording device [21:39] <Freakshow> 2 turn tables? [21:40] <Kingsy> burek: that didnt make a difference.. I am using this command [21:40] <john_doe_jr> burek, I installed pulsecode audio and it shows that 'ALSA plug-in [chrome]' ...I'm recording off an internet site [21:40] <Amnesia> I must admit that I seriously suck at mastering ffmpeg.. [21:40] <burek> Amnesia, noone has been born educated :) [21:40] <Kingsy> burek: ffmpeg -f alsa -ac 1 -async 1 -i hw:1 -f video4linux2 -s 1600x1200 -i /dev/video0 Filename.avi [21:40] <Amnesia> burek: true that [21:41] <Amnesia> but I'm still trying to do the same thing>< [21:41] <Kingsy> burek: its really jumpy and blocky :S [21:41] <burek> Kingsy, did you read the output lines of ffmpeg debug log on screen? did it say something "video driver changed the resolution" [21:41] <burek> Amnesia, stick with us, and you'll learn a lot :) [21:41] <Amnesia> heh [21:42] <Amnesia> working on learning C atm [21:42] <Amnesia> and assembly [21:42] <Amnesia> so time's an issue^^ [21:42] <burek> well, can't be master of everything :) [21:42] <john_doe_jr> burek, now it shows that alsa plug-in [npviewer.bin]: alsa playback is the device it is using [21:42] <Kingsy> burek: not that I can see --> http://pastie.org/3343770 [21:42] <burek> john_doe_jr, [21:42] <Amnesia> true that [21:42] <burek> can you please use pastebin.com, to show your command line and its output? [21:43] <burek> Stream #1.0: Video: rawvideo, yuyv422, 1600x1200, 153600 kb/s, 5 tbr, 1000k tbn, 5 tbc [21:43] <burek> use -s .. -r 25 [21:43] <burek> now it's 5fps :) [21:43] <Kingsy> haha ok [21:43] <Amnesia> ffs [21:44] <Kingsy> burek: it says --> [video4linux2 @ 0x135ba20] The driver changed the time per frame from 1/25 to 1/5 [21:44] <john_doe_jr> burek, well, it's not a command line app...I did a 'sudo apt-get install padevchooser' to get a pulse code audio gui to see what is out putting the sound...I now would like ffmpeg to record the sound [21:45] <john_doe_jr> burek, it still shows 'card 0: AudioPCI [Ensoniq AudioPCI], device 0: ES1371/1 [ES1371 DAC2/ADC]' as the output device though [21:46] <Amnesia> Neither PlayResX nor PlayResY defined. Assuming 384x288 [21:46] <Amnesia> still no bloody subs are appearing [21:46] <burek> Kingsy, your machine isn't fast enough [21:47] <Kingsy> isnt fast enough? its an i7 [21:47] <burek> try using v4l-utils [21:47] <Kingsy> how much faster do you need?? hehe [21:47] <burek> i think its v4l-ctl or something similar [21:47] <burek> wait [21:47] <slackyman> burek, how can i show the supported indevs in ffmpeg? [21:47] <burek> let me remember [21:48] <burek> john_doe_jr, you are making virtual devices with pulse? [21:49] <john_doe_jr> burek, nope..just trying to see what device is out putting the recording....It's recording the sound from hw:0 but when I play back there is no sound.... [21:49] <Kingsy> burek: its v4l-utils .. just searched for it and got it.. [21:49] <burek> slackyman, hmm good question :) [21:49] <Kingsy> burek: but what do I do with it? heh [21:49] <brontosaurusrex> how would one do some motion blur when going from 100fps to 25fps? what filters to use? [21:50] <burek> just a second [21:50] <Kingsy> burek: np [21:50] <slackyman> burek, I don't think there's an option for it [21:50] <john_doe_jr> burek, now I'm getting '[alsa @ 0x2c253e0] cannot open audio device hw:0 (Device or resource busy) [21:50] <john_doe_jr> hw:0: Input/output error' when I run the command but it is already playing at that point [21:50] <Amnesia> anyone known with the padding filter over here..? [21:50] <burek> john_doe_jr, well for ffmpeg it's: ffmpeg -f alsa -i hw:0 out.wav [21:50] <burek> I'm not sure why nothing is recorded [21:50] <slackyman> Amnesia: what do you want to know? [21:50] <burek> what exactly are you trying to accomplish [21:51] <Amnesia> I;m trying to convert 4:3 to 16:9 [21:51] <Amnesia> just compiled ffmpeg since the debian package doesnt ship with libass compiled in [21:52] <Amnesia> but apparantly -padbottom and -padtop are deprecated now [21:52] <slackyman> http://ffmpeg.org/ffmpeg.html#pad [21:52] <Amnesia> yeah reading that:P [21:53] <slackyman> # pad the input to get a final w/h ratio of 16:9 [21:53] <slackyman> pad="ih*16/9:ih:(ow-iw)/2:(oh-ih)/2" [21:53] <slackyman> simple [21:53] <mgeary> hey, can someone remind me of the tool i can use on an mp4 to add/edit the "atom" so it is optimized for progressive playback/streaming? [21:53] <john_doe_jr> burek, I'm trying to record music off a web site...any ideas? [21:54] <burek> Kingsy, v4l2-ctl --list-formats-ext [21:54] <Amnesia> slackyman: tried that, no success [21:54] <slackyman> you have to calculate the values [21:55] <Kingsy> burek: makes sense according to that [21:55] <Kingsy> http://pastie.org/3343879 [21:55] <mgeary> hrm. seems mp4creator does that, but i don't have that on my machine, so i don't think that's what i've used before [21:55] <Amnesia> slackyman: sec:) [21:55] <Kingsy> burek: is there a way of improving it? so I can capture a better resolution? [21:55] <Amnesia> imo the old syntax was easier:).. [21:55] <slackyman> ih = input height - ow = output width - iw = input width etc [21:55] <burek> mgeary, try qtfaststart [21:56] <mgeary> that's it! [21:56] <mgeary> thanks, burek [21:56] <burek> :beer: :) [21:56] <slackyman> Amnesia: the newer is faster [21:56] <Amnesia> I see [21:57] <burek> Kingsy, those are formats your camera supports [21:57] <burek> the best bet is to switch to MJPG pixformat [21:57] <burek> and use -s 1600x1200 -r 15 [21:57] <burek> john_doe_jr, what do you mean record music off a website? [21:58] <Amnesia> hm could one of you tell me how to get the size of the videofile with ffmpeg? [21:58] <burek> slackyman, there is -formats [21:58] <burek> there are in/out devs too [21:58] <Kingsy> burek: how do you set it to mjpg? -f mjpg filename.mpg ? [21:59] <burek> i think -pixfmt mjpg [21:59] <burek> let me check [21:59] <burek> Amnesia, just type ffmpeg -i video.avi [21:59] <brontosaurusrex> mjpg is usually in avi container [21:59] <Amnesia> burek: hm thx [22:00] <burek> Kingsy, -pix_fmt [22:00] <slackyman> burek, yep, I knew the -format trick but I cannot tell the formats from the devices [22:00] <john_doe_jr> burek, I'm listening to music off a website but wanted to know if it is possible to record music off the website [22:00] <Kingsy> and what can I save the file as? a mpg? [22:00] <Kingsy> burek: ^ [22:00] <burek> slackyman, config.log? :D [22:00] <slackyman> burek: it's a trick! >.< [22:00] <Kingsy> burek: or will a avi work? [22:00] <burek> john_doe_jr, that's illegal :D you know :D SOPA :D [22:01] <burek> it is possible [22:01] <slackyman> on an installed binary (repos or download) you doesn't have a conf.log [22:01] <slackyman> :d [22:01] <mgeary> <akbar>It's a trap!</akbar> [22:01] <burek> how does the website stream its music? [22:01] <Kingsy> burek: evidently not, avi and mpg dont work with pix_fmt [22:01] <burek> no no [22:01] <slackyman> I finally compiled librtmp with openssl for Windoz! [22:01] <burek> ffmpeg -pix_fmt MJPEG -s 1600x1200 -r 15 -i /dev/video0 out.avi [22:02] <burek> try that [22:02] <slackyman> and make a huge ffmpeg.exe monolithic binary! [22:02] <burek> +1 :) [22:02] <Kingsy> ah I see [22:02] <burek> slackyman, I'm trying to build a huge fat ffmpeg static binary [22:02] <Kingsy> burek: it says ffmpeg: failed to set value 'MJPEG' for option 'pix_fmt' [22:02] <burek> and when I succeed at it, I'll create cron jobs to regularly do git pull and make the latest binary [22:03] <slackyman> burek: in win or in linux-gnu? [22:03] <burek> so that people dont have to compile it [22:03] <burek> linux [22:03] <burek> but, if we can find a windows host machine for the same thing [22:03] <slackyman> I have one! [22:03] <burek> it would be a killer :D [22:03] <slackyman> burek [22:03] <burek> Kingsy, try MJPG [22:03] <Kingsy> burek: same error [22:03] <slackyman> if you want i can give you my binaries and sources [22:03] <slackyman> and *.sh files [22:03] <burek> hm [22:04] <burek> slackyman, sure :) [22:05] <burek> it would help [22:05] <Amnesia> slackyman: I don't get the coordinates.. [22:05] <slackyman> ?!? [22:05] <Amnesia> 576x240 <- [22:05] <brontosaurusrex> burek, 10 MB would count as fat? [22:05] <burek> Kingsy, try ffmpeg -pix_fmts [22:05] <burek> is there mjpg [22:05] <Amnesia> so that'd be pad="576x240:x:y:black" [22:06] <vadim__> ffmpeg & linux guru, please help ) how to start ffmpeg in background?.. [22:06] <Amnesia> vadim__: ffmpeg .... & [22:06] <john_doe_jr> burek, yup, I know it's possible: http://www.youtube.com/watch?v=i-hGbw1Wb-w&feature=related [22:07] <Kingsy> burek: no not that I can see [22:07] <vadim__> Amnesia: does not work with ffmpeg 0.9.1. it starts in stopped mode [22:07] <slackyman> amnesia, what are the dimensions of your video?

[23:35] <brontosaurusrex> i did, only the canvas size is something that i overlooked [23:35] <Amnesia> I see [23:35] <brontosaurusrex> and i do prefer avisynth syntax : AddBorders(0,72,0,72,0) # pad height 576 [23:36] <Amnesia> hm, also looks like gibberish to me atm [23:37] <brontosaurusrex> well, it doesn't bother with canvas size at all [23:37] <brontosaurusrex> http://avisynth.org/mediawiki/AddBorders [23:37] <Amnesia> I see [23:43] <brontosaurusrex> vadim__, trying to move the atom to the beginning? [23:45] <vadim__> nope, just try to use freshly implemented ismv format from ffmpeg-0.10, but with lack of success yet... [23:46] <vadim__> brontosaurusrex: in fact I try to transcode an avi file to fragmented mp4 (ismv) used for smooth streaming [23:49] <brontosaurusrex> vadim__, interesting, what is needed on server side then? [23:50] <vadim__> brontosaurusrex: pardon, could you explain your question, please... [23:50] <meelu> i want to extract audio from a video, at the bitrate the audio is currently in. The audio in the video is aac i want mp3 how do i do this simply? [23:52] <brontosaurusrex> meelu, ffmpeg -i file -vn out.mp3 (dunno about the same nitrate, doesn't make sense either) [23:52] <brontosaurusrex> bitrate* [23:52] <meelu> same bitrate as in [23:53] <meelu> whatever bitcoin videofile.flv -i gives me [23:53] <meelu> i want to keep it [23:53] <brontosaurusrex> meelu, just extract audio ffmpeg -i file -vn -acodec copy out.m4a [23:53] <meelu> for example if it says [23:53] <meelu> Audio: aac, 44100 Hz, stereo, s16, 151 kb/s [23:53] <meelu> i want a 151 kb/s mp3 [23:53] <meelu> brontosaurusrex, [23:54] <sacarasc> meelu: You can get one... [23:54] <meelu> get one? [23:54] <sacarasc> Acquire. [23:55] <meelu> i could have a default bitrate set, but i'm using this command in a script which will convert various files so different bitrates and i want the mp3's at best possible bitrates which videos already have not extra bitrate or lower bitrate for no reason [23:55] <meelu> so if there is a way... [23:55] <brontosaurusrex> vadim__, to server such streams, what must the server do, or is that just the http ? [23:55] <meelu> sacarasc? [23:57] <brontosaurusrex> meelu, you will transcode (kill quality) with going from arc to mp3, so keeping nitrate is pretty useless [23:57] <brontosaurusrex> aac even [00:00] --- Thu Feb 9 2012

[00:55] <pasteeater> Zeranoe might be able to if he is around. </oblique ping> [00:56] <slackyman> I can't get rid of some compile errors [00:57] <slackyman> Zeranoe, R U here? :D [00:59] <Zeranoe> slackyman: What are you running into? [01:00] <slackyman> I'm on Fedora [01:00] <slackyman> and setted up a good Mingw32 toolchain [01:00] <slackyman> I just compiled ALL other libraries [01:01] <slackyman> libxvid, vorbis, ogg, etc [01:01] <slackyman> x264 [01:01] <slackyman> everything went really good [01:01] <slackyman> and I can compile a really static ffmpeg build with static linked sdl support [01:01] <slackyman> I compiled PolarSSL too [01:02] <slackyman> but I cannot get rid of librtmp compiling errors [01:02] <slackyman> i "gitted" rtmpdump [01:02] <Zeranoe> slackyman: Are you using mingw, or mingw-w64? [01:02] <slackyman> mingw32 not w64 [01:03] <slackyman> I'm on a 32 bit machine [01:03] <slackyman> I modified the Makefile with no success [01:03] <Zeranoe> slackyman: Keep in mind that I still recommend mingw-w64. are you cross compiling? [01:04] <slackyman> yes, but I even tried directy through win [01:04] <slackyman> with windows build of mingw [01:04] <Zeranoe> slackyman: what errors are you getting? [01:05] <slackyman> ok [01:06] <slackyman> first of all, my command is [01:06] <slackyman> mingw32-make SHARED= SYS=mingw CRYPTO=POLARSSL LIBZ="-lz -static" VERSION="2.4" [01:08] <slackyman> http://pastebin.com/ghzKLNad [01:08] <Synthead> so guys, I have six files, video1.avi, video1.mp3, video2.avi, etc. how can I combine all these files into the audio and video tracks of one file? [01:08] <slackyman> as you can see it uses gcc [01:08] <slackyman> not i686-pc-mingw32-gcc [01:08] <slackyman> even if I set CROSS_COMPILE environment [01:09] <Zeranoe> slackyman: You are cross compiling? [01:10] <slackyman> yes [01:10] <slackyman> I'm on a Fedora [01:10] <Zeranoe> you should just be calling make [01:10] <slackyman> I even tried on a windows machine with mingw [01:10] <slackyman> I should... [01:11] <slackyman> but if I go in the Makefile I can see that SYS is set to POSIX [01:11] <slackyman> so i changed to mingw [01:11] <slackyman> and so on [01:11] <slackyman> CRYPTO=POLARSSL [01:12] <Zeranoe> whats your prefix? [01:12] <slackyman> i686-pc-mingw32- [01:12] <pasteeater> Synthead: do you want to concatenate the video and audio into one long video audio and stream? [01:12] <slackyman> export CROSS_COMPILE=i686-pc-mingw32- [01:13] <Zeranoe> slackyman: your install prefix, not toolchain [01:13] <slackyman> so what I can do to cross-compile librtmp [01:13] <slackyman> ?!? [01:13] <slackyman> i even tried mingw32-make [01:14] <Synthead> pasteeater: yeah, that's the idea. I should have read this first: http://ffmpeg.org/faq.html#How-can-I-join-video-files_003f I think what I need to do is encode every pair with two "-i"s (for audio and video), then concat it into a large file, right?

I just want them decoded into mpeg or something I can see in ubuntu [14:34] <sacarasc> You should be able to watch H264 in Ubuntu. [14:34] <sacarasc> (And H264 is an MPEG.) [14:37] <iive> sacarasc: compile mplayer on your own and try to play them with ffplay [14:38] <iive> oops mplayer/ffmpeg [14:38] <sacarasc> Will do! [14:38] <iive> sacarlson: [14:38] <iive> you too [14:38] <sacarasc> Curse these sacar* nicks! [14:38] <iive> blah [14:39] <sacarlson> iive I tired mplayer it does play something but it seems to multiplex between each of the 8 cams in the cctv system when viewed [14:40] <sacarlson> it's mcv version of H264 [14:40] <iive> sacarlson: that's probably how it is encoded. I hope by multiplex you mean that the image is separated on 8 zones [14:40] <sacarlson> yes 8 separate cams some how in one stream [14:41] <iive> i don't think that is mvc, it is a little bit more complicated than that, and afaik supports only 3d stereo. [14:42] <iive> sacarlson: well that's usually how multiplexing is done, even on analog cameras. [14:43] <sacarlson> iive so how do I split the stream into 8 separate mpeg that I can view ? [14:43] <iive> reencode it 8 times, using different -vf crop ? [14:44] <iive> ffmpeg probably can do it at one run, as it allows multi path filter graph [14:44] <iive> but don't ask me what the syntax is. [14:48] <sacarlson> I just tried this ffplay -f h264 07022012170718.264 with many errors [14:48] <sacarlson> didn't see any image that looked like anything [15:10] <iive> sacarlson: is the -f really needed? [15:10] <sacarlson> iive: I don't know I just got it from another link about h264 [15:11] <sacarlson> same error [h264 @ 0x9763320]pps_id out of range [15:11] <sacarlson> [h264 @ 0x9763320]decode_slice_header error [15:14] <sacarlson> the file comes from a hi-view H.264 DVR when I get the file downloaded with a browser [15:19] <sacarlson> I found the file is meant to be played (viewed) with the windows program r6viewer.exe [15:20] <iive> sacarlson: you said you were able to play it with mplayer, do you mean wmp or linux program? [15:21] <iive> -f h264 is probably saying to ffmpeg that the file is elementary stream, but in that case the metadata of the real container could interfere with the demuxing. [15:25] <Bermaw> hi all [15:28] <Bermaw> Just wondering: I want to recieve several network streams and display them synchronously. However, the PTS time field is not really sufficient for this I suppose. [15:30] <Bermaw> Any suggestions on how to get the pts field to use unix timestamps? I also came across AVFormatContext::start_time_realtime. Is that of any use? [15:31] <Mavrik> unix timestamps? [15:32] <Mavrik> if you manage to play video with 1ms granularity you can [15:32] <Mavrik> you just have to set timebases correctly... it's probably not such a good idea though [15:40] <Bermaw> Mavrik: doesn't have to be unix timestamp, that's just easy to agree on. 1ms granularity is not the actual goal either. The video sources just won't be started at the same time, so I do need some way to synchronise it [15:40] <Mavrik> hmm, that's an interesting problem, I think you'll have to do it externally via some service [15:44] <Bermaw> Mavrik: can't I use avpriv_set_pts_info for this? (http://ffmpeg.org/doxygen/trunk/libavformat_2internal_8h.html#ab5542950d6be…) [15:45] <Mavrik> Bermaw, that looks like a private API and you have no guarantee containers/encoders will use it [15:45] <Mavrik> not to mention the problems you'll have with PTS wrapping etc. [15:46] <CommaCrazy> Hey all, I'm trying to conver an image JPEG (.jpg) into a video format MVI (.mvi) using ffmpeg and I always get "Requested output format 'mvi' is not a suitable output format: [15:46] <Mavrik> what's a mvi? [15:47] <Mavrik> CommaCrazy, it seems ffmpeg does not have a MVI muxer [15:48] <CommaCrazy> so wait it saiz that it has support for it but it can't do the conversion?? [15:48] <Mavrik> it has a demuxer, not a muxer [15:48] <Mavrik> - you can decode it but not encode it. [15:49] <CommaCrazy> ah ok ty :) [15:49] <CommaCrazy> c yaz [16:11] <Bermaw> Mavrik: could this be what I am looking for ? http://ffmpeg.org/doxygen/trunk/structAVFormatContext.html#a5ddb5cee1df28f2… [16:12] <Bermaw> The ffmpeg documentation is not always that clear :) [16:39] <Holden> Hello, I recorded a short video using "-f x11grab -vcodec copy", is there a way to see it with ffplay? http://paste.ubuntu.com/832715/ [16:48] <Mavrik> Holden, yick, Matroska doesn't support rawvideo, that's why it complains [16:49] <kyr> hi guys, a certain x264 flag (directpred) won't work for me - I'm saving a mms webcam stream into a 3gp file. Does anyone know the problem? http://pastebin.com/k9EnjEmF [16:50] <Holden> Mavrik, I'm pretty sure it used to work... [16:50] <Holden> Mavrik, do you know of a format that supports rawvideo? [16:51] <Mavrik> hmm [16:51] <Mavrik> Holden, you can try putting -vodec rawvideo before the -i spec in ffmpeg/ffplay if it'll work [16:52] <Mavrik> Holden, and for output it seems people just recommend dumping video in raw form with -f rawvideo [16:52] <Mavrik> (I never did that though) [16:57] <Holden> Mavrik, okay thanks, now I'm curious and I'll compile and older version, maybe I'm remembering wrong... [17:21] <Holden> Mavrik, hmm, yes, it works with 0.8.10 http://paste.ubuntu.com/832785/ [17:40] <kyr> ok i got it working (install x264 wrong) but now it's not grabbing the stream at all [17:41] <kyr> aaand wrong version. sorry, installing it on a vps [17:44] <kyr> fml [17:56] <wl2776> Hi all! Is it possible to remux raw h264 to MKV without re-encoding *and* specify PTS for every frame [17:58] <slackyman> hi [17:59] <wl2776> I have a separate file, containing timestamps, I can convert it to any format... Is it possible then to use them with command line ffmpeg? [18:10] <sacarlson> I still haven't found a method to decode this h264 file from a cctv stand alone unit that files can be viewed in a program called r6viewer.exe for windows. I just want one of the 8 streams encoded in the file in an avi or other format to be viewe or broadcast [18:10] <sacarlson> I normaly run ubuntu but if there is a windows alternative I'll try it [18:14] <sacarlson> I see many different vendors of these cctv servalance systems all use this r6viewer.exe and I can't even find the software vendor that wrote it [18:32] <mgeary> why would this give me no video output? http://dpaste.com/699090/ [18:32] <mgeary> ffmpeg -i input.mov -ac 1 -ar 22050 -vf scale=546:-1 out.flv [18:33] <mgeary> hmm. it says it has a video track, but quicktime (perian) isn't showing anything. weird [18:38] <slackyman> someone here is a C++ expert? [19:07] <kelnoky> I used this "ffmpeg -i DSN_-_ST05_Epi_01_-_Eng-Dt.avi -map 0:v -map 0:1 DSN501.avi" to basically remove one of the two audio steams that the input had, but the result has *terrible* quality, what did I do wrong? [19:08] <kelnoky> terrible video quality that is [19:14] <kelnoky> I actually forgot to copy the video... [19:14] <kelnoky> never mind me... [19:20] <slackyman> I saw that error and log messages of ffmpeg are colored [19:20] <slackyman> I'd like to reuse the code used to color messages in console [19:20] <slackyman> where I can find it? [19:20] <jermy> http://en.wikipedia.org/wiki/ANSI_escape_code [19:20] <slackyman> I can't get past av_fprint_format [19:21] <slackyman> jermy: yes, but it doesn't work in win console [19:21] <slackyman> windows doesn't accept ANSI code [19:22] <slackyman> ok, thanks [19:22] <jermy> I see. Is there some stuff in liavutil/log.c specific to Windows? [19:22] <jermy> #define set_color(x) SetConsoleTextAttribute(con, background | color[x]) [19:22] <jermy> for example [19:23] <slackyman> thanks A LOT :D [19:23] <jermy> you're welcome [19:24] <kyr> hi again, I'm still getting "Unrecognized option 'directpred'" (though i fixed my other problem). can anyone tell me where did i mess up? [19:34] <kyr> lol. my bad [19:34] <kyr> learn something new every day i guess [20:17] <matthiaskrgr> how do I loop/append the last frame of a video until it is of certain length? [22:09] <amoeba> I have several terabytes of H246 MP4 video with 2 audio tracks. The 1st track contains a left and right channel. The left channel is one language. The right channel is a second language. The 2nd track is a third language in the left channel. What I need is to extract the left and right from track 1 as well as the left channel from track 2 and then save the 3 to separate tracks. is this Possible with FFMPEG? [22:11] <amoeba> anyone know? [22:53] <gils> @amoeba I don't know about ffmpeg, but you can split stereo to mono with sox using the "remix" option [23:03] <mgeary> so, i've just compiled from source, using "configure --enable-libmp3lame --enable-gpl --enable-libx264", but it appears to be having problems with aac. [23:04] <mgeary> http://dpaste.com/699210/ [23:11] <mgeary> any insights? [23:11] <iive> mgeary: ffmpeg have its own aac encoder, that is slow and produces bad quality. that's why it is disabled by default and you have to enable it with -strict -2 option [23:12] <mgeary> should i use mp3 instead? [23:12] <iive> it is better if you use libfaac or ... forgot the name of the other encoder. [23:12] <iive> for mp3 you would need libmp3lame [23:13] <mgeary> iive: do i need to specify libfaac when compiling? [23:13] <iive> mgeary: i think you do need to. [23:25] <mgeary> hmm. so i'm using mp3 audio now, and it converted, but for some reason, my audio came out shifted 7 seconds. In other words, i have 7 seconds of black video, but with audio, and then no audio for the last 7 seconds of the video [23:26] <mgeary> this is when playing back in Quicktime. Interestingly, ffmpeg says the output is 30.43 seconds, but Quicktime says it's 37.07 [23:30] <iive> the input.mov video says it starts -6.6 seconds ... that's about 7 seconds. [23:30] <iive> can you try a newer version of ffmpeg. there must be 0.10 now too. [23:32] <mgeary> well, i just barely did a "git pull" before compiling just now [23:34] <iive> oh, i think i saw 0.9.1 version, so i assumed it is release [23:34] <iive> sorry. [23:35] <mgeary> well, it does say that [23:35] <mgeary> is there a different git repo i should be using? [23:36] <mgeary> is there a git equivalent to "svn info" ? [23:37] <iive> `git status` maybe? [23:37] <iive> it would at least tell you the current branch :) [23:37] <tdr> mgeary, if you are looking for svn ffmpeg, there is a -9999 version in portage, but there's also a 0.10 release in portage too [23:39] <mgeary> i'm pulling anew. Just using "git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg" [23:39] <mgeary> will that get 0.10 ? [23:50] <iive> mgeary: i hope so. [00:00] --- Wed Feb 8 2012

[02:18] <Anthony> I would like to make a high quality mp4 from an mkv file [02:18] <Anthony> what kinda command should i use [02:18] <Anthony> ? [02:21] <Anthony> bcoudurier » [02:21] <Anthony> supercurio » [02:21] <Anthony> `md » [02:21] <Anthony> iive » [02:21] <Anthony> anyone [02:23] <iive> Anthony: don't highlight people when you don't get answer [02:23] <Anthony> ok [02:23] <iive> especially when you ask question that google can also answer. [02:24] <Anthony> i should be more specific sorry [02:24] <Anthony> what should I put for -vpre [02:25] <Anthony> i just want the max quality [02:27] <Anthony> i came up with a command but not sure if it's the best [02:27] <Anthony> ffmpeg -i input.mkv -s 1280x692 -r 24000/1001 -b 2M -bt 5M -vcodec libx264 -vpre max -acodec libfaac -ac 2 -ar 48000 -ab 192k output.mp4 [04:32] <pills> I have 4 videos I am trying to combine into a single video. This is easy enough to do using the video filter options. My problem is the input videos don't seem to decode properly (first frame is dropped). This seems to be due to how they were encoded wrt timecodes. I can fix this problem for a single video by adding the -vsync 0 option however when combined with the video filters only the first video seems to inherit the vsync option. Is [04:32] <pills> there anyway around this (reencoding is fine and if so what would be the "right" way)? Thanks. [05:11] <XiL> Was wondering if Debian GNU/Linux 3.1 supports Turbo Boost. cat /proc/cpuinfo is just a label afaik. [05:11] <XiL> Got quite a lot of rendering to do [05:14] <XiL> using a i7 2700k [05:19] <drv> turbo boost doesn't really matter if you are doing multi-threaded encoding anyway [05:19] <drv> since it only takes effect when only a single core is loaded [05:22] <XiL> drv true but some parts of my script (grabs the source ffmpeg VLC and kdenlive with all the bells and whistles and compiles them to play nice) would be faster. [05:23] <drv> i think it is automatically done by the CPU, but i don't know for sure [05:24] <XiL> drv a lot of ppl say that is the case and others swear it not. At this point idk. [05:24] <drv> well, you could always try it out and measure the cpu clock speed :) [05:25] <XiL> time ffmpeg -i thing yeah true.

[10:26] <ubitux> what's the most common way of encoding aac nowadays? [10:26] <ubitux> libfaac is deprecated afaik, libaacplus? libvoaac? [10:28] <JEEB> I don't think libfaac is deprecated, it just shares status with libaacplus [10:29] <JEEB> as in, "you can't give the binaries out" [10:29] <JEEB> libvoaac seems to be... something [10:29] <JEEB> generally I'd say that on linux you might as well stick to neroaacenc [10:30] <ubitux> < JEEB> libvoaac seems to be... something // what's that supposed to mean? :) [10:30] <JEEB> on mac/win you have a selection of either neroaacenc or one of those QT-based command line encoders [10:30] <Mavrik> ubitux, libvo_aacenc is the replacement library [10:30] <ubitux> replacement of what? [10:30] <JEEB> it really isn't a full replacement I hear quality-wise + it can only do 2ch [10:30] <Mavrik> of libfaac - libfaac has licensing problems [10:30] <JEEB> but it's the only non-ffaac encoder that is (L)GPL compatible [10:30] <Mavrik> JEEB, it's pretty much same reference design, but you're right about 2-channel [10:31] <JEEB> Mavrik, I think they used separate reference encoders [10:31] <JEEB> but yes, reference code both [10:31] <JEEB> just that one was licensed and relicensed to apache by someone actually capable of it [10:31] <Mavrik> mhm [10:31] <JEEB> also, I _think_ libvo-aacenc can only do CBR [10:31] <JEEB> not sure [10:32] <Mavrik> sadly, neroaacenc can't be linked with ffmpeg :\ [10:32] <JEEB> yes, and as it would be closed source it'd be undistributable [10:32] <JEEB> just like QT's aac encoder would be on windows [10:32] <JEEB> on OS X QT is a part of the OS so it might fly [10:33] <JEEB> of course, neroaacenc doesn't have a library to begin with [10:33] <JEEB> only executables [10:33] <JEEB> QT's actually has an API [10:33] <JEEB> neroaacenc doesn't need QT to be installed of course, and there is a 32bit linux binary [10:33] <JEEB> so yeah [10:34] <Mavrik> so yeah, getting quality AAC audio in automated video encoding is problematic as hell [10:36] <JEEB> Well, if that's all you're looking after you either use ffaac or make a ffmpeg patch for the QT encoder .-. But that of course means that you have to build it on every PC and can't distribute it. [10:36] <Mavrik> JEEB, my use case is mostly automated transcoding on servers, so non-redistributable license doesn't bother me all that much [10:37] <Mavrik> right now I'm using libfaac yeah, getting AAC+ on higher bitrates would probably prove beneficial (most content is voice - lectures) [11:20] <rbrt> hello! [11:20] <rbrt> is there a way to use audio filters with ffplay ? [11:22] <rbrt> there is an option "-vf" for video filters, but "-af" for audio does not work [11:23] <ubitux> yes, no -af option yet [11:23] <ubitux> but you can use ffplay -f lavfi 'amovie=...' [11:25] <rbrt> but this only plays the audio track. [11:26] <ubitux> you can append filter [11:26] <ubitux> rbrt: what are you trying to do? [11:26] <ubitux> ffplay -f lavfi 'amovie=a.wav,aresample=8000,aconvert=...,pan=...' [11:27] <rbrt> i have a .avi file with "5.1" ac3, but i have only stereo output, so i want to use the pan filter [11:27] <ubitux> -ac 2 should downmix it properly [11:28] <ubitux> maybe you want custom levels? [11:29] <ubitux> ffmpeg -i in.avi -f lavfi 'amovie=in.avi,pan=...' out.avi should do the trick otherwise [11:29] <ubitux> ffmpeg -i in.avi -f lavfi -i 'amovie=in.avi,pan=...' out.avi [11:29] <ubitux> sorry [11:32] <rbrt> well, yes, i tried it, but that does not work with ffplay. maybe i have to convert it first, and play the converted? [11:33] <ubitux> mmh maybe ffplay -f lavfi -i 'movie=in.avi[out0];amovie=in.avi,pan=...[out1]' or something? [11:36] <rbrt> there is an "audio filters" section in ffplay man page, but there is no option to actually use them with ffplay. is this right? [11:37] <ubitux> isn't the example above making use of the audio filters? [11:39] <ubitux> ./ffplay -f lavfi 'movie=a.mov [out0]; amovie=a.mov,aresample=8000 [out1]' [11:39] <rbrt> ffplay -f lavfi "amovie=foo.avi[out0];movie=foo.avi[out1];pan='stereo: c0=FL : c1=FR'" says its expecting channel name, but found 'FL' [11:39] <ubitux> i just tested that and it seems to work [11:39] <ubitux> mmh [11:40] <ubitux> iirc the pan filter has an issue with channel names [11:40] <ubitux> try c0=c1 : c1=c0 [11:41] <ubitux> rbrt: btw, aren't you just trying to do -ac 2 ? [11:41] <rbrt> that says : "Not enough inputs specified for the "pan" filter" [11:41] <ubitux> you didn't write the filter properly [11:41] <rbrt> i tryed "-ac 2", but its the same result without any filter option [11:42] <ubitux> "movie=foo.avi[out0]; amovie=foo.avi,pan='stereo: c0=FL : c1=FR'[out1]" [11:42] <ubitux> try this [11:42] <ubitux> or just "movie=foo.avi[out0]; amovie=foo.avi,pan='stereo: c0=c0 : c1=c1'[out1]" [11:42] <ubitux> this will filter out the other channels btw [11:45] <rbrt> it seems that the 5.1 isthe last one played only audio, no video. thank you for your time, but i will convert that movie with ffmpeg. it seems to be lot easier. [11:45] <rbrt> the last one played only audio, no video. thank you for your time, but i will convert that movie with ffmpeg. it seems to be lot easier. [11:45] <rbrt> sorry [15:17] <bgmarete> Hi. ffmpeg gives me an error when I try to give it the `-profile' option, as in `-profile main' when using libx264. What may I be doing wrong? [15:18] <wl2776> Hi all. Is it possible to remux raw h264 video to matroska? I'm getting error "Can't write packet with unknown timestamp". Tried -fflags +genpts -vf "setpts" - no effect. Here is paste: http://pastebin.com/q3htv5wF [15:18] <Mavrik> bgmarete, there's a parameter collision with libfaac [15:18] <bgmarete> Oh! [15:18] <Mavrik> bgmarete, use "-profile:v main" or if you have older ffmpeg "-vprofile main" [15:18] <bgmarete> Mavrik: Thank you very much! Many thanks. [16:30] <loincloth> hallo [17:48] <SIFTU> anyone got any tips to keep audio in sync when merging multiple mpg2's for dvd output? [18:19] <elihubogan> Does anyone have tips on exporting a ProRes422HQ file to something I can use in Cinelerra? [18:19] <elihubogan> I keep getting files that are <20% of my original, and I think it's got to be lossy [18:21] <elihubogan> currently trying "ffmpeg -i <infile.mov> -sameq -vcodec mpeg4 <outfile.mov>" [19:26] <boghog> hi there, is there some known problem with reading video files with mp4/mov containers that indicate absurdly high framerates? (like 1200fps) I have a problem with a file that seems to take ages to transcode, and I notice that un the status line it prints that it has processed over 91000 (ish) frames, even though the output framerate is set to 30 automatically and duration shows 5 minutes, the 'dup' count seems to have a very high number [19:26] <boghog> too (I guess that might make sense if dup stands for duplicate) [19:27] <boghog> it shows something like: frame=121047 fps= 85 q=29.0 size= 54506kB time=00:06:43.34 bitrate=1107.0kbits/s dup=108957 drop=0 [19:29] <boghog> http://pastebin.com/PESGP0Tn is the full ffmpeg output [19:30] <boghog> I guess it has something to do with the mismatch between container and video stream framerate [19:33] <boghog> it also occurs to me that in the status line, (frame-dup)/29.98 equals roughly 6:43, so it seems to be just processing duplicate frames or something? :s [20:40] <boghog> managed to sort of fix my problem by passing -vsync 0 [20:40] <boghog> well not sort of, it fixed it entirely [20:42] <boghog> I'm only a bit worried on what potential sideeffects -vsync 0 might produce in videos that don't need it [20:42] <boghog> since I'm using ffmpeg for automated conversion of video files [21:30] <slackyman> hi [21:31] <slackyman> I found a little buggy behaviour in ffmpeg and ffplay [21:32] <slackyman> if you compile ffmpeg and ffplay without librtmp the protocol rtmp is still included but if you try to play via rtmp the player freeze [21:32] <slackyman> so ffmpeg [21:32] <slackyman> without any notice or alert [21:32] <slackyman> it simply hangs [21:38] <slackyman> I was about to report this bug in the forum but I have to wait my account approvation [21:39] <slackyman> Ok, I read: "The new official forum, that will be located at forum.ffmpeg.org, is being created, and because of that, registrations of new users on this forum has been disabled" [21:39] <slackyman> but the forum is not yet ready [21:40] <slackyman> any1 here? :D [22:14] <slackyman> helloooo [22:14] <boghog> hi! [22:14] <slackyman> hi [22:15] <slackyman> boghog, have U read what I wrote? [22:15] <boghog> yeah, but not much I can help with [22:16] <boghog> in fact I only came in here to get help with a problem of my own :D [22:16] <slackyman> I have another problem [22:16] <slackyman> maybe we can hellp one each other :D [22:17] <slackyman> I cannot compile librtmp [22:17] <slackyman> in linux and mingw32 [22:17] <slackyman> either [22:17] <slackyman> no matter [22:17] <boghog> what error? [22:17] <slackyman> i want to compile librtmp statically linked to polarssl [22:18] <slackyman> uhm [22:18] <slackyman> several errors :D [22:18] <slackyman> can I compile only librtmp with something such as [22:18] <slackyman> make librtmp? [22:19] <slackyman> dh.h:75:3: warning: pointer targets in passing argument 3 of 'dhm_calc_secret' differ in signedness [-Wpointer-sign] [22:19] <slackyman> this is the firts error I can notice [22:20] <slackyman> I modified tha makefile [22:20] <slackyman> CRYPTO=POLARSSL [22:20] <slackyman> SYS=mingw [22:22] <Gus> Hi. Is it a known bug of recent ffmpeg versions that the features --enable-runtime-cpudetect and --enable-mmx, --enable-mmx2, --enable-sse etc. have become mutualy exclusive? [22:23] <Gus> By enabling both CPU detect and asm features I get "runtime cpu detection yes" but "MMX enabled no [22:23] <Gus> MMX2 enabled no [22:23] <Gus> 3DNow! enabled no" etc. [22:25] <slackyman> Gus, I'm not an expert in C and C++ programming but I suppose that runtime-cpu-detect excludes any other cpu optimisation is useless [22:25] <slackyman> or maybe... [22:25] <slackyman> lemme check a thing [22:25] <Gus> slackmagic: I think this behaviour of mutual exclusion is new. [22:26] <slackyman> I don't have this issue [22:26] <Gus> Typically, enabling MMX, SSE etc. means that the code gets built and is usable within the binary. CPU runtime detection should check upon program start whether the optimized code *may* be used (whether the CPU supports it). [22:26] <slackyman> yasm yes [22:26] <slackyman> MMX enabled yes [22:26] <slackyman> MMX2 enabled yes [22:26] <slackyman> 3DNow! enabled yes [22:26] <slackyman> 3DNow! extended enabled yes [22:26] <slackyman> SSE enabled yes [22:26] <slackyman> SSSE3 enabled yes [22:26] <slackyman> AVX enabled yes [22:27] <slackyman> runtime cpu detection yes [22:27] <Gus> slackmagic: including specifying --enable-runtime-cpudetect? [22:27] <Gus> Hmmm. [22:27] <slackyman> I've re-tryed my ./configure [22:27] <slackyman> maybe there's something more [22:27] <slackyman> i.e. I notice other strange behaviours [22:28] <Gus> I just noticed that this new build of mine is significantly slower on some aspects than earlier versions. [22:28] <slackyman> if i use --enable-libxavs I have to modify CFLAGS and --extra-libs to get SDL to be recognised [22:28] <Gus> Which is due to the fact that no hardware optimizations, not even MMX, are used for scaling any more here. [22:28] <slackyman> else ffplay cannot be compiled [22:29] <slackyman> yes [22:29] <slackyman> can I see your configure switches? [22:29] <pasteeater> Gus: did you --disable-mmx? [22:29] <slackyman> use pastebin or someone get pissed :D [22:29] <Gus> pasteeater: not at all. [22:29] <Gus> pasteeater: as mentioned above, I explicitly enabled all CPU features. [22:30] <pasteeater> i just entered the channel, so i have little context. [22:30] <Gus> Version 0.9.1 from January 2012 here, btw. [22:30] <slackyman> I didn't and they've enabled [22:30] <slackyman> Gus, try only the --enable-cpu-runtime [22:30] <Gus> pasteeater: this is my original point: Hi. Is it a known bug of recent ffmpeg versions that the features --enable-runtime-cpudetect and --enable-mmx, --enable-mmx2, --enable-sse etc. have become mutualy exclusive? [22:30] <slackyman> and what's the result? [22:31] <Gus> Gus> By enabling both CPU detect and asm features I get "runtime cpu detection yes" but "MMX enabled no [22:31] <Gus> <Gus> MMX2 enabled no [22:31] <Gus> <Gus> 3DNow! enabled no" etc. [22:31] <slackyman> I don't think so [22:31] <slackyman> please, try ONLY --enable-runtime-cpudetect and let's see the output [22:31] <Gus> I don't want to go without runtime CPU detection since the build is to be used on different machines, including some older ones which do not have SSE. [22:31] <Gus> Okay. [22:32] <slackyman> I'm still finding a way to compile librtmp with polarssl in mingw32... -.- [22:32] <slackyman> f***ing windoz [22:33] <Gus> slackmagic: however, something must have changed inm the configure script. Because I use the same options set for more than two years. [22:34] <Gus> I mean: slackyman ;-) [22:34] <slackyman> this can be really true, yes [22:34] <slackyman> my nick means slcakware user even if I'm on a Fedora and a Windowz machine :D [22:35] <Gus> Only CPU runtime detection given, no other --enable-swicthes set. Result: CPU detection enabled, all CPU features disabled, still. [22:35] <slackyman> I'm really so tired to recomplile every prog [22:35] <slackyman> it's the latest snapshot? [22:36] <slackyman> or you get it by git? [22:36] <slackyman> i got mine by gittin [22:36] <Gus> slackyman: snapshot. [22:36] <slackyman> and I have none of this problem [22:36] <Gus> From january. [22:36] <slackyman> ok, try the git one [22:37] <slackyman> just to make a proof [22:37] <Gus> Haven't Git available atm. [22:37] <slackyman> a little test [22:37] <slackyman> which distro R U using? [22:37] <Gus> slackyman: LFS. [22:37] <slackyman> omg >.< [22:38] <Gus> That's why I use configure and not apt-get, emerge or yast or something like that ;-) [22:38] <slackyman> cannot simply get git? [22:38] <Gus> Not that simply. [22:38] <slackyman> and that's why I'm using Fedora and not Slackware [22:38] <slackyman> :D [22:38] <Gus> Besides, I doubt that a fortnight in versions could make this big difference,. [22:39] <Gus> A-ha! I got it! [22:39] <Gus> The culprit was another switch! [22:39] <slackyman> I remember... yes, I used a january snapshot without inconvenience a pair of day ago [22:39] <slackyman> yeah? [22:39] <slackyman> which one? [22:40] <Gus> --cpu=i586 [22:40] <slackyman> -.- [22:40] <Gus> That one seems to exclude all other CPU features. [22:40] <Gus> However, this is new behaviour. [22:40] <slackyman> I'm tempted to let you go to HELL >.< [22:40] <Gus> Formerly the --enable-feature switches would override the --cpu= restriction. [22:40] <slackyman> no, really, I think it's ok [22:41] <slackyman> "formerly", in my opinion, means nothing :D [22:41] <Gus> As said, I use the same options for more than two years. Just this new build became significantly slower than older ones. [22:41] <Gus> However, it's nearly a year since my previous build :-S [22:41] <Gus> So I don't know when this behaviour was changed. [22:42] <slackyman> I don't use CPU if I'm building a portable one [22:42] <slackyman> all the job is done by the runtime detection [22:42] <slackyman> it costs only a little bigger binary [22:43] <Gus> slackyman: in case of ffmpeg: apparently true. In case of most other software: there isn't CPU runtime detection. That's why I use to specify it explicitly at build time. [22:43] <slackyman> can I ask U a question? [22:43] <Gus> slackyman: sure. [22:43] <slackyman> a PAIR of question [22:43] <slackyman> :D [22:43] <slackyman> 1 - Have you ever succeded in compiling librtmp? [22:44] <slackyman> (with polarssl) [22:44] <Gus> 1. not recently but I think some years ago I probably did. But most likely not with polarssl, since I don't know what that is. [22:45] <slackyman> I forgot the second question :P [22:45] <Gus> Well, I didn't knwo what that is :-) [22:45] <Gus> I use OpenSSL and GnuTLS instead. [22:45] <Gus> I think I managed to compile something capable of RTMPS, if that's your goal. [22:46] <slackyman> it seems that for windows I can use polarssl since openssl lacks some bugs in win [22:46] <Gus> Windows? Uhm... [22:46] <Gus> I don't use Windows at all. [22:46] <slackyman> I'm into a portable project [22:46] <Freakshow> anyone know how to explicitly force rtsp over tcp with ffmpeg? [22:46] <slackyman> and I need to compile ffmpeg for Linux and Win [22:47] <Gus> ffmpeg can be compiled under Windows? [22:47] <Gus> Every day I learn something new about that OS :-) [22:47] <slackyman> gus, I compile ffmpeg under Linux FOR windows [22:47] <slackyman> with mingw32 [22:48] <slackyman> and then test it in bot [22:48] <Gus> Mingw32 on Linux?? [22:48] <slackyman> I'm writing a wrapper in Lazarus - fpc [22:48] <slackyman> yes [22:48] <slackyman> since I think that WinFF it's not so simple to use I re-write my lazarus app from scratch [22:49] <slackyman> for windoz users [22:49] <slackyman> i wanna give the app almost all the ffmpeg features [22:49] <slackyman> with a good GUI [22:49] <Gus> slackyman: brave intention. [22:49] <slackyman> and under gpl3 [22:49] <Gus> Very brave intention :-) [22:50] <slackyman> I've just written a console wrapper [22:50] <Gus> Freakshow: using ffserver? [22:50] <slackyman> do you know SUPER? [22:50] <slackyman> I think it violate gpl [22:50] <slackyman> but I'm not sure [22:51] <Freakshow> Gus: I'm sorry, as in the target for the stream? [22:51] <meta_> Hi all folks! Can someone help me, at least to name what is my problem, as i can't really google for it... http://www.youtube.com/watch?v=OVEo3TRsUAM#t=5m30 [22:51] <meta_> It isn't moves too fast, but horizontally flickers [22:51] <meta_> I've made this in blender, and it uses ffmpeg [22:51] <Freakshow> if so, then the short answer is no [22:52] <Gus> Freakshow: target for a stream sounds like a job for ffserver to me. [22:52] <Freakshow> shooting to wowza [22:52] <meta_> So what's the name of this syndrome? And maybe any idea about how can i fix it? [22:52] <Gus> Freakshow: or do you mean reading from an rtsp source and encoding, possibly transcoding the data? [22:52] <Freakshow> Gus: nope, shooting to wowza and fanning out from there [22:53] <slackyman> meta_ [22:53] <slackyman> are you talking about the video on youtube? [22:53] <meta_> yes [22:53] <slackyman> I can see it good, without flickkering [22:53] <meta_> it flickers the same on the original also, i know it's converted [22:53] <meta_> oh... [22:53] <Gus> Freakshow: sorry, I'm not familiar with Wowza Media Server. [22:53] <slackyman> could it be your player? [22:54] <slackyman> have you tried to see it on another machine? [22:54] <meta_> i've tried vlc, mplayer, on my host os, on an older version ubuntu in vbox, and in xp in vbox [22:54] <Freakshow> Gus: I doubt wowza really has anything to do with it in this instance, is there a way to tell ffmpeg to publish rtsp over tcp? [22:54] <slackyman> meta_ try it on another hardware [22:54] <meta_> hmm... [22:54] <slackyman> i can see NO FLICKER [22:55] <Gus> Freakshow: I don't think so. ffmpeg isn't the publication tool. It's the read and store tool. ffserver is the read and publish tool. [22:55] <slackyman> the video goes well and fluid [22:55] <meta_> It's not really flicker, i just can't name it [22:55] <meta_> if you see the edges it isn't fluid... yeah... for me it seem, i'm going to check elsewhere [22:55] <Gus> Freakshow: however, ffserver seems somehow limited regarding protocols and format. I don't know whether it supports rtsp. [22:55] <meta_> thanks! [22:56] <overflow_0f8b> how do you call it when a line has common part with a rectangle ? line_has_common_part_with_rect() sounds long [22:56] <slackyman> i can see the video fluid and flawless [22:56] <Gus> Btw, does anyone know whether there's been any progress in adapting ffserver (or the ffmpeg suite as a whole) to v4l2 lately? [22:56] <Freakshow> hmm... gotta be a way [22:56] <Freakshow> { "tcp", "TCP", 0, AV_OPT_TYPE_CONST, {1 << RTSP_LOWER_TRANSPORT_TCP}, 0, 0, DEC|ENC, "rtsp_transport" }, \ [22:56] <Freakshow> in const AVOption ff_rtsp_options [22:56] <slackyman> anyone here ever compiled rtmp for windoz?!? [22:57] <slackyman> I'm getting REALLY mad [22:57] <Freakshow> calm down slackyman [22:57] <Freakshow> breathe [22:57] <slackyman> Freakshow: I'm not mad with this chan :D [22:58] <slackyman> I'm mad with librtmp [22:58] <slackyman> :D [22:58] <Freakshow> oh, I'm in the same boat with you there [22:58] <Freakshow> :D [22:58] <Gus> I'd get mad just if I had to build anything ambitious for Windoze at all ;-) [22:58] <slackyman> I compiled EVERY SINGLE lib for win to use them with ffmpeg [22:58] <slackyman> with only a little patch [22:58] <meta_> wow [22:59] <slackyman> but librtmp is a damned hell [22:59] <Freakshow> nice Gus [22:59] <Gus> slackyman: what sorts of errors? [22:59] <Freakshow> I had a hard enough time building it for bsd, I can't imagine doing it for windows [22:59] <slackyman> every sort [22:59] <slackyman> :) [22:59] <Gus> slackyman: same as on Linux or Windows-specifc ones? [22:59] <Freakshow> HA! [22:59] <slackyman> rtmp cannot find polarssl [23:00] <Gus> slackyman: so primarily link errors and not compile errors? [23:00] <Ginks> would anyone be able to show me how I can merge these into 1 command? [23:00] <Ginks> -vf "scale=-1:720" & -vf movie=/srv/www/vhosts/testing.com/htdocs/data/watermark.png [logo]; [in][logo] overlay=10:10 [out] [23:00] <slackyman> gus, the fact is that I tested different versions and had different issues [23:01] <Gus> slackyman: did you test any version that had none of the issues on Linux? [23:01] <Freakshow> agreed... compiling librtmp is not very clear on any platform [23:01] <Gus> So are you sure the issues are fully Windows-specific? [23:02] <slackyman> on linux i can compile rtmp with openssl but have issues with polarssl [23:02] <Gus> slackyman: what are the issues with OpenSSL on Windows? [23:02] <slackyman> gus, I'm cross-compiling [23:02] <slackyman> but here in Italy it's late and I'm tired [23:02] <slackyman> :D [23:03] <Mavrik> Ginks, movie=...,scale=... [23:03] <Gus> Have you tried building it natively on a Windows machine? [23:03] <Mavrik> Ginks, add comma ;) [23:03] <slackyman> librtmp seems to NOT work with openssl in win [23:03] <Gus> slackyman: link errors? [23:03] <Gus> Or does it link but not run? [23:03] <slackyman> no no [23:03] <slackyman> doesn't link [23:04] <Gus> At least link errors are often easier to solve than runtime errors I think :-S [23:04] <slackyman> cannot find polarssl/net.h [23:04] <Gus> That's a compiler error. [23:04] <slackyman> even if i #include <polarssl/net.h> [23:04] <Gus> Should be even easier to solve than a link error. [23:04] <slackyman> or something I cannot remember [23:04] <Gus> In this case I usually locate the missing header file manually, copy it to somewhere where it can be included and retry :-) [23:05] <slackyman> but, really, it's too late and I'm on the phone with my girlfriend so... goobye :D [23:05] <Ginks> Mavrik, oh [23:05] <Ginks> lol [23:05] <Gus> Once I got it working I then may check why the error occurred and how to solve it in a way that could be easier applied by others. [23:05] <Gus> slackyman: bye. [23:05] <slackyman> just tried [23:05] <slackyman> i put polarssl build EVERYWHERE [23:05] <slackyman> :D [23:06] <slackyman> in /usr/local [23:06] <slackyman> into the librtmp folder [23:06] <slackyman> in rtmpdump folder [23:06] <Gus> slackyman: just deal with the missing .h file. [23:06] <Gus> Copy it into /usr/include for the time being if necessary. [23:06] <slackyman> yeah, that was my goal [23:06] <slackyman> :D [23:07] <slackyman> I copied in /usr/local/include and /usr/include [23:07] <slackyman> i tried even with [23:07] <slackyman> #include "polarssl/net.h" [23:07] <Gus> Well, if the compiler cannot find it there, then there seems to be a serious problem with your build environment. [23:07] <slackyman> and [23:07] <slackyman> #include <polarssl/net.h> [23:07] <slackyman> but none [23:08] <slackyman> gus, I doubt [23:08] <slackyman> with my env I compiled everything :D [23:08] <slackyman> openssl, divxlib, freetype [23:08] <slackyman> sdl [23:08] <slackyman> everything [23:08] <slackyman> and they needed only feww changes [23:08] <Gus> Then you can't tell me that if you have a file x.h in /usr/include and have #include <x.h> in your sources it doesn't find it? [23:09] <slackyman> gus, it's not so simple with mingw32 [23:09] <slackyman> it create another toolchain env [23:09] <Gus> Put it into your standard include directory of Mingw32. [23:09] <Gus> In the same one that provides stdlib.h for instance. [23:09] <slackyman> ok, I'll give it a try, but now I've to go [23:09] <Gus> Bye. [23:09] <slackyman> thanks anyway [23:10] <slackyman> bye [23:10] <Ginks> Mavrik, [23:10] <Ginks> ffmpeg -i hot.flv -an -vf "scale=-1:720,movie=/srv/www/vhosts/testing.com/htdocs/data/watermark.png [logo]; [in][logo] overlay=10:10 [out]" -f mp4 scaled.mp4 [23:10] <Ginks> I tried it a few ways with commas and got different errors [23:11] <Ginks> ffmpeg -i hot.flv -an -vf "movie=/srv/www/vhosts/testing.com/htdocs/data/watermark.png [logo]; [in][logo] overlay=10:10 [out]", scale=-1:720 -f mp4 scaled.mp4 [23:12] <Ginks> I need to have it scale and then overlay [23:12] <Ginks> so that the watermark doesn't become distorted [23:27] <Ginks> ffmpeg -i hot.flv -an -vf "movie=/srv/www/vhosts/testing.com/htdocs/data/watermark.png, scale=-1:720 [watermark]; [in][watermark] overlay=10:10 [out]" -qscale 1 -f mp4 scaled.mp4 [23:27] <Ginks> [overlay @ 0x192ecda0] Overlay area (10,10)<->(2224,730) not within the main area (0,0)<->(320,240) or zero-sized [23:27] <Mavrik> obviously your overlay parameters are wrong. [23:28] <Ginks> if I split the command into 2 and run the scale first and then watermark after it works [23:29] <Ginks> trying to put them together is where apparently the overlay parameters are incorrect [23:30] <Ginks> if I swap scale to before movie then I get Too many inputs specified for the "movie" filter.

[00:00] <brontosaurusrex> jackNDbox, it depends on what you want to do later, i just : --enable-gpl --enable-libx264 --enable-libvpx [00:01] <jackNDbox> i'm building a porn site and a video sharing site [00:01] <jackNDbox> using phpmotion [00:02] <jackNDbox> for one of em [00:03] <brontosaurusrex> i mean ffmpeg, do you need mp3 encoder for porn? or theora? probably not [00:03] <jackNDbox> yea youre probably right. ffmpeg automatically does audio .. right? just in a lower quality? [00:04] <jackNDbox> I was just being lazy following that guide above [00:06] <brontosaurusrex> well, video sites this days usually encode to AVC/AAC in some form or another, webm (You would probably want aotuv oggenc here anyway) is also somehow interesting [00:07] <brontosaurusrex> i don't know anybody that would use xvid/mp3 this days [00:07] <brontosaurusrex> only my opinion... [00:09] <brontosaurusrex> p.s. actually even libvpx is kinda useless, its almost impossible to find correct command line, better to just pipe from ffmpeg to vpxenc anyway [00:10] <jackNDbox> makes sense.. the stuff before that [00:10] <jackNDbox> thanks for the info i'll be back here probably in a little while [00:10] <jackNDbox> i'm gonna go get a pizza =) [00:10] <iive> jackNDbox: look for the phrase "mp3lame" in that log file [00:22] <brontosaurusrex> how to encode to 444 prores, command line? [02:47] <Ginks> any idea why ffmpeg would seg fault with "ffmpeg -i 253_temp.flv -vf "movie=/home/mypetman/public_html/images/watermark.png [watermark]; [in][watermark] overlay=10:10 [out]" -b:v 472k 253_w.flv" [02:47] <Ginks> ? [02:47] <Ginks> only happens with flv videos [02:51] <edrx> hello - how do I reduce the number of frames of a video? it's for recording a conference with few slides and a speak that does not move too much... the camera produced a .mov with 24 fps, and I'd like to reduce that to 8 fps by keeping only 1 in each 3 frames... [02:52] <edrx> s/speak/speaker/ [02:54] <edrx> (btw, I am on debian, and using the command line) [03:14] <rypervenche> Hi all. My screencasting script broke a while back, apparently due to an update in ffmpeg. It uses x264, however at first I record lossless data. I have since fixed my script using "-vcodec libx264 -preset ultrafast", but is this lossless data? Should I be using somethign else? [03:16] <rypervenche> Before I was using -vpre lossless_ultrafast. Is there still a lossless option or should I only use the ultrafast option? [03:38] <iive> rypervenche: just a moment [03:42] <rypervenche> iive: Thank you. [03:45] <iive> it will take a little bit more time to compile 0.10 release. in the meantime [03:45] <iive> you can get lossless by encoding with quantizer 0 in x264 [03:46] <Ginks> qmax, qmin, qscale? [03:47] <Ginks> I'm going to take a video and add an overlay to it [03:47] <iive> either by -qscale 0 (that's ffmpeg option ) or -x264opts qp=0 [03:47] <rypervenche> iive: So they removed the lossless preset then? This is the only way to get a lossless video? [03:48] <Ginks> just want to get the best quality prior to encoding it to 264 [03:48] <Ginks> size doesn't matter, because I'll be encoding it with 264 [03:48] <iive> rypervenche: seems so, the .ffpreset files are gone [03:49] <iive> there is x264-ipod*.ffpreset [03:49] <iive> are [03:50] <iive> hum, there is -qp 0 (ffmpeg option maped to x264 directly). [03:52] <iive> hum, it says rate control method.... huh [03:56] <iive> n8 ppl [04:54] <pills> I have 4 videos I am trying to combine into a single video. This is easy enough to do using the video filter options. My problem is the input videos don't seem to decode properly (first frame is dropped). This seems to be due to how they were encoded wrt timecodes. I can fix this problem for a single video by adding the -vsync 0 option however when combined with the video filters only the first video seems to inherit the vsync option. Is [04:54] <pills> there anyway around this (reencoding is fine)? Thanks. [05:14] <burek> try to reencode your videos [05:14] <burek> to get valid streams [05:14] <burek> and then use filter [05:14] <burek> or even better, if you have room on your hdd, use uncompressed version :) [05:15] <burek> and only compress back when using the filter [05:15] <burek> that way you recompress only 1 time [05:34] <pills> what params do I feed the encoder to ensure they will be decoded correctly? [08:48] <Sazpaimon> mind if i ask a general streaming question around here? [08:49] <Sazpaimon> (yes I know I'm asking to ask, sorry) [12:38] <necktie> hi. can anyone help me with updating ffmpeg and x264? i compiled both from svn/git. is there an easy command that will get the up to date? or do i have to completely re-compile them? [12:41] <tdr> yep, rebuild them [13:02] <LexSfX> necktie: write a short script for yourself that simply performs the git and build commands you used in the first place. [13:13] <necktie> LexSfX: alright, i will try. thanks [14:35] <necktie> hi. i'm trying to compile ffmpeg but i get this error "WARNING: Please upgrade to VA-API >= 0.32 if you would like full VA-API support.". what does this mean and how can i fix it? [14:39] <necktie> anyone? [15:11] <iive> necktie: you need newer vaapi libraries.or newer distro [15:11] <Mavrik> necktie, your va-api library is too old [15:12] <Mavrik> and you won't be able to use nVidia hardware acceleration [16:05] <dragos240> Hello. I'm having a few issues streaming through rtsp with ffserver. My config file is here http://pastebin.com/vmNghAhJ and the command I use to stream to the ffserver is here along with the error message I recieve http://pastebin.com/wQLuSw0r [16:06] <dragos240> I've been troubleshooting for a while and I cannot figure out for the life of me why this hates me. [16:07] <dragos240> Oh. And my ffmpeg version is the latest git revision that I checked out 30m ago. However stable versions act the same way [16:21] <mystica555_> dragos240: i could be wrong, but i dont think mu-law or a-law support 44.1khz ? [16:21] <dragos240> Hm [16:21] <mystica555_> i thought they were 8 bit 8khz (with 11bits effective sample loudness resolution due to non-linear quantization scale) [16:22] <dragos240> We are talking about the sample rate, correct? [16:23] <mystica555_> mostly; also it doesnt seem that stream2.sdp is even being parsed by ffmpeg to create the codecs as you list (i dont know whether or not it even is supposed to pull from there, but if you notice in your debug output there are no -acodec or -vcodec bits, and its seemingly choosing mu-law randomly instead of libfaac) [16:24] <mystica555_> nor is it using libx264 as the video codec [16:24] <mystica555_> try adding -acodec libfaac -b:a your-bitrate -vcodec libx264 [16:24] <mystica555_> to your commandline [16:25] <mystica555_> and probably -b:v 128K as well [16:25] <mystica555_> -b:a 64K [16:25] <mystica555_> or something [16:25] <mystica555_> granted, hes ircing as root, that doesnt entirely show critical thinking skills [16:25] <mystica555_> (which i find are required to parse logs) [16:27] <dragos240> I noticed that. [16:27] <dragos240> I don't know why it randomly does that. [16:28] <dragos241> I kept getting disconnected [16:29] <mystica555_> fwiw you may not want to IRC as root; if there is a backdoor or a known vulnerability in your client, anyone could just 0wn your system. [16:29] <dragos241> Right. [16:29] <dragos241> I'm not using root now, but I was. [16:29] <mystica555_> i suggest adding commandline options to ffmpeg to force video/audio codecs; the SDP file is simply what the rtsp client pulls for its own config i believe [16:30] <mystica555_> and bitrates for that matter [16:30] <mystica555_> something like: -acodec libfaac -vcodec libx264 -b:a 64K -b:v 128K [16:30] <dragos241> Hm. [16:30] <dragos241> I'll see if that does anything [16:30] <mystica555_> it should do a lot of things [16:31] <mystica555_> because if you compare your SDP file to the actual debug output of ffmpeg, you arent matching on any counts [16:32] <mystica555_> except for framerate and capture size, which you specify on the commandline [16:32] <dragos241> Hm. Now this is an odd result [16:32] <dragos241> Unknown decoder 'libx264' [16:33] <dragos241> I could probably switch to theora and vorbis and see if that does anything. [16:34] <Mavrik> libx264 is not a decoder [16:34] <Mavrik> the decoder is probably called "h264" [16:35] <dragos241> I'll try that [16:36] <dragos241> Okay. I changed libx264 to h264 and libfaac to aac. I get a new error. [16:36] <dragos241> [alsa @ 0x14dcda0] sample format 0x15002 is not supported [16:36] <dragos241> hw:0,0: Input/output error [16:37] <dragos241> It's complaining about sample format. Maybe the sample rate is to blame? [16:39] <dragos241> Changing both config and command line instances of 22050 to 8000 does not fix the problem. But those may be invalid. [16:43] <mystica555_> try opening the device as plughw: vs hw: [16:43] <mystica555_> that'll force a software samplerate conversion if required [16:43] <mystica555_> (some chips are limited to 48khz) [16:44] <mystica555_> Mavrik: i thought he was using this to encode, not decode [16:44] <dragos241> [alsa @ 0x1ed0da0] sample format 0x15002 is not supported [16:44] <dragos241> plughw:0,0: Input/output error [16:45] <mystica555_> hrm.. [16:45] <mystica555_> i hate alsa and sound recording... [16:46] <dragos241> Is there a way I can tell ffserver and ffmpeg to ignore sound altogether? [16:46] <mystica555_> -acodec null iirc [16:46] <dragos241> Nope. Not a decoder. [16:47] <dragos241> That would have been my first thought though [16:47] <dragos241> The aim here is to stream video, audio is second. [16:49] <mystica555_> where are you putting the option in your encode commandline? it is position-sensitive [16:50] <mystica555_> if you do it before -i its a decoder option, if its after the -i file, its the encoder it seems [16:50] <dragos241> Hm. That may explain it then [16:51] <relaxed> dragos241: -an [16:52] <mystica555_> dragos241: so you'd probably want libx264 and libfaac again [16:53] <dragos241> Yes I did that mystica [16:53] <dragos241> As it complained to me [16:53] <mystica555_> k [16:53] <dragos241> Now I put -af, -acodec, and -vcodec in front of -i this time with their proper parameters [16:54] <dragos241> As well as -b:a and -b:v [16:54] <dragos241> Here is what I fed ffmpeg [16:54] <dragos241> ffmpeg -f x11grab -r 25 -s 384x240 -i :0.0 -f alsa -i hw:0,0 -acodec libfaac -vcodec libx264 -b:a 64K -b:v 128K -ar 8000 -f rtp rtp://192.168.1.102:8090/stream.sdp [16:55] <mystica555_> do you need 8khz? 64kbit will support 44.1 mono, 22.05 stereo [16:56] <dragos241> Ah. No I was trying to get this to work before hand. Let me try 22050 on both the config and ffmpeg args [16:56] <mystica555_> k [16:57] <dragos241> Alright those were changed. I'm back to previous errors: [16:57] <dragos241> Could not write header for output file #0 (incorrect codec parameters ?) [16:57] <mystica555_> can you pastebin the full output again? [16:57] <dragos241> Yes. Give me a second to do that. [16:58] <dragos241> http://pastebin.com/LtUKSSyn [17:00] <dragos241> Fortunately now, the correct codecs are being used [17:01] <necktie> hi. can anyone help me understand how to crop? i want to crop the black bars from a video. i need to crop 2 pixels on the left, 4 right, 20 top, and 28 bottom. the video is 1920x1080. [17:04] <mystica555_> dragos241: i can't seem to find the proper documentation to understand how this all works...but im seeing examples of commandlines pointing to a .ffm file instead of a .sdp file; or simply doing an rtp address as rtp:localhost:port [17:04] <mystica555_> after -f rtp [17:06] <dragos241> I will see if changing that has an effect. However, I need an sdp file for a program that I use. But if this works, I'll see if it accepts the ffm. [17:07] <pingec> necktie -cropleft 2 -cropright 4 -croptop 20 -cropbotoom 20 ? [17:07] <pingec> I have a raw h264 file that is recognized as data. It has no header, I am able to play it only with "ffplay -f h264 aaa.264" is there a way I could create a header for this file so that it gets recognized in every player? Or can I convert it into a legal file without any actual transcoding? [17:07] <dragos241> pingec: I don't think that works on newer versions of ffmpeg [17:07] <dragos241> Evidently they use -vf crop now. As for how it works, I'm stumped. [17:08] <pingec> ah [17:08] <necktie> pingec: ya. it used to be that simple. now it's hard as hell. at least for me [17:08] <pingec> get an older version :P [17:08] <pingec> the options are still listed in the help tho [17:09] <dragos241> Hm. That's curious. Maybe someone's neglecting to update the man files? [17:09] <necktie> i've read the documentation. i still have no clue [17:09] <Mavrik> dragos240, http://ffmpeg.org/libavfilter.html#crop [17:10] <mystica555_> pingec: try doing ffmpeg -f h264 -i yourfile -vcodec copy something.mkv/mp4 and it'll mux it for you [17:11] <mystica555_> then being inside said container format will fit your requirement of universal recognisability [17:11] <pingec> thanks lets try [17:11] <necktie> Mavrik: ya. that's what i read. still can't figure it out. can you help? i don't want the answer, i just want to figure out how it works [17:11] <Mavrik> for cropping, it's simple [17:12] <Mavrik> you apply the crop filter with "-vf crop=<parameters>" [17:12] <Mavrik> where you pass parameters delimited with semicolons - as in documentation "out_w:out_h:x:y" [17:12] <Mavrik> meaning, if you want to crop a 400x400 rectangle, starting at 100,200 you pass [17:12] <Mavrik> -vf crop=400:400:100:200 [17:13] <Mavrik> there are examples right under the description in the documentation file [17:13] <necktie> Mavrik: so how would i get the parameters for 2 pixels on the left, 4 right, 20 top, and 28 bottom. the video is 1920x1080. [17:14] <Mavrik> -vf crop=in_w-6:in_h-48:2:20 [17:14] <Mavrik> (your box has to be (2+4) smaller in width, (28+20) smaller in height and it has to start on 2,20 [17:14] <mystica555_> dragos241: oh btw i just read your comment about the sdp file; the sdp file should be made by the server and present in its web dir; it seems to be wrong or unused for how to describe to ffmpeg where to stream [17:14] <pingec> mystica555_ thanks, great trick this copy parameter [17:14] <mystica555_> pingec: i just got done remuxing some divx+mp3 into .mp4 containers for my HP Touchpad because it couldnt demux .avi :\ [17:15] <mystica555_> but...now, COSMOS IN BED! [17:15] <pingec> hehe :) [17:15] <necktie> Mavrik: i think i get it now. thanks so much! :) [17:16] <dragos241> 07:18 < dragos241> mystica555_: Yeah the info on it is kinda sparce [17:16] <dragos241> I don't know if that went through [17:16] <dragos241> I lost connection for a tad [17:16] <mystica555_> it didnt [17:16] <mystica555_> first time im seeing the line ;) [17:16] <dragos241> Just wanted to ensure it went through [17:17] <mystica555_> k [17:17] <dragos241> Now, experimenting with feeds and streams. The stream depends on a local feed. [17:17] <dragos241> It doesn't seem to be picky what it's called nor what extension it uses [17:18] <dragos241> The feed that is [17:18] <mystica555_> im not sure i follow what context of 'feed' and 'stream' you are using [17:19] <dragos241> Oh, sorry [17:19] <dragos241> In the config you have a feed and a stream [17:19] <dragos241> The feed is what ffmpeg passes into to, and the stream is read from a media player once info from ffmpeg is passed. [17:19] <dragos241> For example a feed would be feed.ffm [17:20] <dragos241> A stream may be stream.mp4 [17:20] <mystica555_> ok [17:20] <dragos241> In my case, my feed is stream.sdp and my stream is stream2.sdp [17:21] <mystica555_> ok [17:21] <mystica555_> i can only wonder whether or not ffmpeg is doing some auto-guessing based on extension [17:21] <mystica555_> thus perhaps naming it .ffm would let ffmpeg know what its doing better 8shrug* [17:22] <Mavrik> ffmpeg chooses demuxer depending on the extension, so yeah ;) [17:22] <dragos241> Interesting [17:22] <dragos241> Naming the feed stream.ffm did nothing [17:23] <mystica555_> hm [17:24] <dragos241> However. I still have the output to when I did that [17:24] <dragos241> I'm posting it on pastebin [17:24] <mystica555_> k [17:24] <dragos241> http://pastebin.com/UUpHFwiz [17:25] <dragos241> Whilst I can't see anything different here, maybe there's something minute. [17:28] <dragos241> Also if you need the stream file. I have that too. [17:29] <dragos241> The current one uses the sdp. [17:29] <dragos241> It was posted earlier, but since has been changed. [17:29] <dragos241> http://pastebin.com/Kh3eUUja [17:30] <necktie> Mavrik: one last question. the video is 1920x1080. and i plan on encoding it as 720p. do i need to scale or set dar/sar to do this? or do i just do -s 1280x696? 696 would be the new height instead of 720 due to the cropping.. [17:32] <mystica555_> dragos241: what happens if you omit -f rtp from your output ? [17:33] <dragos241> Ah. I think I've tried that. It interprets the output as a file. [17:33] <dragos241> And says it cannot find it. [17:33] <dragos241> I'll try again though [17:33] <dragos241> [NULL @ 0x23358b0] Unable to find a suitable output format for 'rtp://192.168.1.102:8090/stream.sdp' [17:33] <dragos241> rtp://192.168.1.102:8090/stream.sdp: Invalid argument [17:34] <dragos241> Is the result. [17:34] <mystica555_> try http for the stream feed file [17:35] <mystica555_> afaik http is how the static files get served; rtp is simply for the live stream data [17:35] <dragos241> Hm. I just wiped the audio codec argument and replaced it with -an [17:35] <dragos241> It works [17:35] <mystica555_> ah interesting [17:35] Action: mystica555_ again decries alsa recording [17:36] <dragos241> Not sure if it plays though [17:36] <Mavrik> necktie, I suggest you do scale, -s is deprecated [17:36] <Mavrik> necktie, also, you'll have to put scale filter AFTER crop filter (obviously) [17:37] <Mavrik> so something like [17:37] <Mavrik> -vf crop=in_w-6:in_h-48:2:20,scale=-1:696 [17:37] <Mavrik> this will crop video and scale it while keeping the aspect ratio [17:43] <necktie> Mavrik: when i try that, i get this "width not divisible by 2 (1281x696)" [17:44] <Mavrik> yuck [17:45] <Mavrik> I would have thought the scale filter can fix that [17:45] <Mavrik> necktie, you can just manually set scale=1280x696 [17:45] <Mavrik> er [17:45] <Mavrik> scale=1280:696 [17:53] <necktie> Mavrik: that worked. thanks again [17:58] <Tjoppen> what's the way to use x11grab nowadays? -f x11grab etc. says "Unknown input format: 'x11grab' [17:58] <Tjoppen> even though configura has --enable-x11grab [17:59] <Mavrik> Tjoppen, check ffmpeg -formats [18:00] <Tjoppen> ffmpeg -formats|grep x11 -> nothing [18:00] <Tjoppen> let me update to latest master [18:01] <Mavrik> Tjoppen, also, funny thing I noticed: if you're missing x11-dev libs, ffmpeg compiles without x11 support even if you go --enable :) [18:02] <Tjoppen> !! [18:02] <Tjoppen> libx11-dev is already the newest version. [18:04] <Tjoppen> yep, master doesn't work either [18:05] <Tjoppen> libxcb-image0-dev perhaps? [18:18] <Tjoppen> libx11-xcb-dev mayhaps [18:18] <Tjoppen> nope.avi [18:23] <Tjoppen> there we go. needed libxext-dev and libxfixes-dev [18:24] <Mavrik> wow :) [18:27] <Tjoppen> today's quest: grab desktop, webcam, microphone and output audio while maintaining sync [18:30] <Mavrik> hah, good luck :) [18:32] <Tjoppen> might want yuv444p for the capture.. h.264 doesn't support rgb I suppose? [18:32] <Tjoppen> I wonder.. ffv1 perhaps [18:33] <Tjoppen> yep. excellent [18:34] <Mavrik> Tjoppen, x264 supports RGB, but not via ffmpeg afaik [18:35] <Tjoppen> ic. well, I think ffv1 will suffice [18:35] <Tjoppen> or did it not do inter compression? [18:38] <Tjoppen> apparently not. libx264 + losless_ultrafast + yuv444p it is then [19:28] <tokam> how to convert an mkv video using ffmpeg to mp3 [19:31] <tokam> unknown encoder .mp3 [19:36] <tokam> libmp3lame is missing [20:35] <Peace-> just compiled [20:35] <Peace-> colorspace not supported in LJPEG [00:00] --- Mon Feb 6 2012
