[00:36] <darkstarbyte> What is the best way to compress video with vp8? (the source is animation) [01:06] <desti> how can i display the available presets for libx264? [01:19] <darkstarbyte> desti, x264 --fullhelp [01:21] <desti> hmmm....doesn't work 0.o [01:29] <desti> ah, had to merge x264-encoder too [01:57] <ibkanat> is there a way to luma key video and export alpha .pngs? [01:58] <ibkanat> with ffmpeg [01:59] <ibkanat> I wanting to key out snow and leave the skiier [02:07] <Synthead> Hey, what options would you guys recommend to encode video for an iphone on 4.2.1 (3G) ? [02:13] <ibkanat> is lutyuv what I am looking for? [02:20] <ibkanat> anyone with any ideas on how to do this? [02:21] <filam> ffmpeg -i audio.wma audio.wav brings up a warning about "wmalossless" and exits. Am I missing an option? I would like WAV not WMA lossless. [03:02] <ibkanat> so can frei0r filter be used from the command line? [04:19] <ibkanat> is there somewhere else I can get answer t ousing ffmpeg -vf lutyuv [04:20] <acerimmer> ibkanat: https://lists.ffmpeg.org/mailman/listinfo/ffmpeg-user/ [04:21] <ibkanat> thanks I am really just trying to do one color to alpha [04:21] <ibkanat> whiteish [04:22] <acerimmer> ibkanat: I'm new to ffmpeg myself. I signed up for the user list and it's VERY active. Suggest you submit your query to them. [04:22] <ibkanat> k [04:36] <sam1> hi guys. What does it mean "New video filter 'sub' to burn ASS and SRT subtitles." in FFmbc-0.7-rc4 ? [05:18] <llrcombs> so, it turns out those THP files weren't fixed by building latest git [05:19] <llrcombs> I mediafire'd a few, I'll link in a sec [05:20] <Randy_T> Is it possible to specify the baseline profile for x264 in ffmpeg. I tried -vpre baseline -profile baseline and -x264opts profile=baseline. Not a big deal since i can just specify the 4 options that baseline uses but if it exists, i'd like to use it. [05:34] <llrcombs> http://www.mediafire.com/?w4d6rz648sg8y <-- Fire Emblem cutscene files. FE10 files transcode perfectly with ffmpeg; FE9 files get artifacts. I need some help! [05:36] <llrcombs> relaxed: you here? [05:39] <llrcombs> actually, one FE10 cutscene file doesn't transcode properly, but I think the filename "DUMMY" explains that... [05:41] <relaxed> llrcombs: I'm here [05:41] <llrcombs> relaxed: I posted those THPs [05:41] <llrcombs> the latest git doesn't help [05:41] Action: llrcombs is uploading a few more now [05:42] <relaxed> I'm downloading s01.mov [05:43] <llrcombs> that one's fine right up until the last few seconds [05:43] <llrcombs> it started erroring in the last several frames, and it gets rainbows [05:43] <llrcombs> the audio is fine on all of them [05:43] <llrcombs> the s0x's are deinterlaced [05:43] <llrcombs> (as are all the ones from FE9) [05:44] <llrcombs> download the THP too; it's the original [05:45] <llrcombs> and if Mist's voice actress bugs you, it's not just you. That's everyone. [05:46] <llrcombs> the really bad one is s05 [05:52] <relaxed> is there an issue with s01.thp? [05:52] <llrcombs> relaxed: last few seconds rainbowify [05:52] <llrcombs> haven't tested that one with latest git, though [05:53] <llrcombs> once I checked s05 with latest, I figured nothing had changed [05:54] Action: llrcombs tries with latest git [05:54] <relaxed> I see it [05:55] <llrcombs> same with s03 [05:55] <llrcombs> it's not a bad gamerip; they all play fine in-game in Dolphin [05:55] <relaxed> Are ytou sure the files aren't damaged? [05:56] <relaxed> you* [05:56] <llrcombs> ^ [05:56] <relaxed> oh [05:56] <relaxed> Then, yeah, go ahead and file a bug report [05:56] <llrcombs> I thought Dolphin might've screwed up the extraction, but I re-extracted them multiple times with different dolphin versions [05:56] <llrcombs> and the other files extracted fine [05:57] <llrcombs> do you know much about THPs? [05:57] <relaxed> I do not [05:57] <llrcombs> it's a format used only in Wii/GCN games [05:57] <llrcombs> motion JPEG + some specific THP PCM audio [05:58] <llrcombs> and a weird encapsulation [05:58] <llrcombs> it's basically the wii/GCN equivalent of Bink [05:59] <llrcombs> afaik, there's no official spec on it, so files extracted from wii/GCN titles are the definitively "valid" files that ffmpeg should be decoding properly [05:59] <llrcombs> where do I file a bug report? [06:01] <relaxed> llrcombs: http://ffmpeg.org/bugreports.html [06:02] <llrcombs> thanks, reporting [06:02] <relaxed> make sure you add links to the samples [06:03] <llrcombs> should I just link to the main folder and list file paths within? [06:05] <relaxed> sure [06:06] <llrcombs> does mediafire count as ridiculous, bloated and span-filled crap? [06:06] <llrcombs> I usually don't class it with megaupload/rapidshare [06:06] <relaxed> right, I think it will be fine [06:07] <darkstarbyte> Anyone know of a really good bench marking tool that can read the level of functions? [06:07] <relaxed> llrcombs: or you could use dropbox http://db.tt/cDWPLzP [06:20] <llrcombs> relaxed: does this go under FFmpeg, avcodec, or avformat? [06:21] <darkstarbyte> ffmpeg will not take avi to mkv directly it complains there is no time stamp [06:21] <darkstarbyte> , but [06:21] <darkstarbyte> it will take avi to mp4 then mkv [06:22] <llrcombs> darkstarbyte: tested with latest git? [06:22] <darkstarbyte> Latest stable [06:22] <llrcombs> try master [06:22] <darkstarbyte> ok [06:22] <darkstarbyte> It might take a while to compile [06:23] <llrcombs> what platform? [06:24] <darkstarbyte> pentium 4 ht 64 bit arch linux (not optimized for it though) [06:26] <darkstarbyte> It seems that git ffmpeg requires it deps to be git [06:27] <llrcombs> yeah, that happens sometimes with deps [06:27] <llrcombs> grab the new deps too [06:27] <darkstarbyte> I might as well [06:27] <darkstarbyte> My arch system is broken and won't let me update [06:28] <darkstarbyte> Are there any distos that have a decent tool chain and some what easy to make packages for? [06:28] Action: llrcombs is on OSX, no idea [06:29] <darkstarbyte> hackintosh? [06:29] <llrcombs> yep [06:30] <darkstarbyte> x264 does not take to long to compile [06:30] <llrcombs> didn't take long here [06:31] Action: llrcombs compiled latest git and some deps earlier today [06:31] <darkstarbyte> done [06:33] <darkstarbyte> ffmpeg takes my computer about 15 minutes to compile last I checked [06:33] <llrcombs> sounds right [06:33] <darkstarbyte> Last I checked I was running gentoo [06:33] <darkstarbyte> Last time* [06:34] <darkstarbyte> How much do you know about vp8? [06:34] <llrcombs> a little [06:35] <darkstarbyte> Do you know of any good settings for animation? [06:35] <llrcombs> nope, sorry [06:37] <darkstarbyte> I should get some sleep tonight. [06:48] <llrcombs> http://www.mediafire.com/?a4j6s38nq6mz2 <-- can anyone identify these files? [06:49] <llrcombs> the ones without extensions were .cms files; I extracted them with an LZ77 extractor python script. I have no idea what format they're in [06:49] <llrcombs> I just know they're captions [06:59] <darkstarbyte> I am going to be up for a little longer, but [06:59] <darkstarbyte> I was wondering what I should use to copy the audio and video of another format [07:00] <darkstarbyte> because -acodec copy and -vcodec copy no longer work with the git source [07:04] <llrcombs> oh, I've been wondering that too [07:04] Action: llrcombs gets unrecognized codec "copy" [07:04] <llrcombs> or something alike [07:09] <darkstarbyte> good night before I can't get any sleep. [07:15] <llrcombs> relaxed: https://ffmpeg.org/trac/ffmpeg/ticket/903 <-- posted a bug report [07:22] <relaxed> llrcombs: good. btw, -sameq doesn't work with libx264 [07:25] <llrcombs> relaxed: oh, thanks for the tip [07:25] <llrcombs> does it work with libmp3lame? [07:26] <llrcombs> and how can I set it to use the highest possible quality given the input? [07:27] <relaxed> you can use a lossless codec or libx264 with -crf 16 should look lossless [07:30] <llrcombs> what's crf? [07:30] <llrcombs> (just out of curiosity) [07:31] <llrcombs> also, does anyone know of any subtitle/caption format that would be binary data, rather than normal text? [07:31] <relaxed> llrcombs: and to deinterlace use yadif, so ffmpeg -i input -vf yadif -vcodec libx264 -preset veryslow -threads 0 -crf 16 -acodec flac output.mkv [07:31] <llrcombs> what, is -vf yadif better than -deinterlace? [07:31] <relaxed> yes [07:32] <relaxed> crf = constant rate factor (vbr) [07:32] <llrcombs> gotcha [08:03] <shevy> when I cut an avi file, like so [08:03] <shevy> ffmpeg -i input.avi -ss 50 -t 100 output.avi [08:03] <shevy> does this have to be re-encoded? [08:04] <sacarasc> If you tell it to copy, it might work. [09:39] <Peasley> Can I take frame from AVCODEC_DECODE_VIDEO directly and display it? [09:53] <Peasley> kind of confused what am getting from avcodec_decode_video [09:54] <Peasley> data has 3 arrays, 16bytes, 128 bytes, 128 bytes [11:42] <gst-kaps> is it possible to stream as well as record at same time using ffmpeg ? [12:39] <Mavrik> huh [12:39] <Mavrik> libvo-aacenc and libfaac have same function names -_- [13:39] <artcontr> Hi everyone. I have a question about ffmpeg. Can someone explain in more details what mjpeg codec is used by the -vcodec mjpeg command ? What codec should I use to decode it ? [14:01] <Mavrik> artcontr, mjpeg is Motion JPEG format [14:01] <Mavrik> http://en.wikipedia.org/wiki/Motion_JPEG [16:50] <apus> hi, i have an input file with stream Stream #0:3(eng): Subtitle: text (default) and i just want to take it with me (no options for subtitles), the mapping then says Stream #0:3 -> #0:2 (? -> ass) and i get the error Decoder (codec text) not found for input stream #0:3 [17:14] <saste> apus: -> http://ffmpeg.org/trac/ffmpeg [17:14] <saste> you need to login in order to create a ticket [17:15] <apus> saste: i found two pastebin entries having the same error in google, therefore i assumed it was perhaps already known (approx. 1 month ago) [17:50] <Bombo> i got a DVB mpg file with 720x576 16:9 (SAR 64:45) i want to cut the borders off, top 61, bottom 62, left 4 and right 6, does this filter settings make any sense? -vf crop=in_w-(4+6):in_h-(62+61):4:61,scale=in_w:in_h/sar,scale=640:-1 [17:51] <Bombo> (and scale it to 640x$WHATEVERTHEHEIGHTISTOKEEPTHEPROPORTIONS) [17:52] <Bombo> and the result looks ok to me, but i'm not sure about the two scales, can it be done in one scale only? [17:58] <shevy> hmm ffmpeg -i is synonymous to ffmpeg -input ? can I use the long versions? [18:04] <Bombo> shevy: does it work? [18:05] <Bombo> never tried it [18:07] <shevy> Bombo not sure either hehe [18:07] <shevy> just my brain that likes to look at long names [18:09] <Bombo> well lets wait for someone who tries it out for us then ;) [18:50] <relaxed> Bombo: scale=640:out_w*(sar/dar) [19:25] <Bombo> relaxed: nope, image is too high, long faces [19:26] <Bombo> relaxed: i get 640x407 then [19:26] <Bombo> with scale=in_w:in_h/sar,scale=640:-1 i get 640x286 [20:48] <khali> since I updated to the latest version of ffmpeg, -alang is no longer supported [20:48] <khali> and I can't find the replacement [20:48] <khali> does anyone know? [20:56] <khali> found it... -metadata:s:1 language=eng [20:57] <khali> now I need to find the replacement for -newaudio... [20:58] <vcs> khali: one second, let me dig through my notes [20:58] <vcs> i have it [20:59] <vcs> what you need to do is use -map [20:59] <vcs> example: ffmpeg -i input.avi -map 0:0 -acodec libmp3lame -map 0:1 -acodec aac out.avi [21:03] <khali> it used to be 0:1... [21:03] <khali> 0.1; sorry [21:03] <khali> and now it's 0:1 [21:03] <khali> so man command line interface changes in one go... [21:04] <vcs> it went from not making sense to making sense [21:04] <vcs> can't complain about that :) [21:05] <khali> vcs: oh, there certainly were good reasons for all these changes, I'm not questioning that [21:05] <khali> and in one week I'll have forgotten the old names and I'll be happy [21:06] <khali> but right at the moment, it's a pain to adjust my script with the new syntax [21:06] <vcs> welcome to the club [21:16] <tholm> hi, I'm trying to compile ffmpeg 0.9.1 for armv4, I'm on debian lenny version but getting this error "Assembler messages: [21:16] <tholm> Error: bad immediate value for 8-bit offset (1032)" [21:16] <tholm> But I made the compilation with these arguments --disable-asm and --disable-optimizations [21:16] <tholm> Does it make sense? I mean when you compile for a arm processor it needs disable the asm instruccion? [22:00] <vostok4[nv]> hey guys i'm trying to do a rather straightforward cross compile of ffmpeg for windows, under archlinux. i'm running into the following when running configure: http://codepad.org/TqkTzASK [22:01] <vostok4[nv]> its complaining about undefined references to _vpx_codec_control when linking the test vpx encoder [00:00] --- Tue Jan 10 2012
