[00:05:03 CEST] <Mavrik> ac_slater_, b-frames have nothing to do with it
[00:05:24 CEST] <Mavrik> av_interleaved_write will just make sure that packets in different streams will go out in DTS order
[00:05:50 CEST] <Mavrik> so if you write stream 1 with DTS 55, 65, 75 and after that you write stream 2 with DTS 50, 60, 70
[00:06:00 CEST] <Mavrik> your output will be 50, 55, 60, 65... interleaved packets
[00:06:13 CEST] <Mavrik> if you use normal write then your output will be written in the order you do
[00:06:42 CEST] <IlIlIlIlIlIlI> Mavrik, btw, did you see, '-vsync drop' resolved all non-monotonous DTS issues with tee muxer I was having ^^
[00:07:16 CEST] <Mavrik> hah :)
[00:07:17 CEST] <ac_slater_> Mavrik: awesome - I remember you saying that now. I don't know if my platform stress out too much if I did interleaved writes.. I assume something has to buffer
[00:07:55 CEST] <Mavrik> ac_slater_, yeah that depends, usualy that's useful because if you do threaded encoding you still want to keep audio packets close to corresponding video packets
[00:08:16 CEST] <Mavrik> otherwise strange stuff can happen if the difference between streams when sent over network is larger than device buffer :)
[00:08:16 CEST] <ac_slater_> Mavrik: right. And I am doing threaded encoding ... maybe I should try it and see
[00:08:32 CEST] <ac_slater_> ha I can imagine
[00:08:42 CEST] <Mavrik> basically I've seen cases where audio packets came in 4 seconds after video packets and STBs didn't like that :P
[00:08:49 CEST] <Mavrik> for most usecases that's not as important
[00:08:58 CEST] <Mavrik> since you're rarely have such difference
[00:10:15 CEST] <ac_slater_> I'm trying to normalize stuff like that with some IPC that coordinates this stuff ... ie - the video is the main source of PTS/DTS timestamps as it's the most frequent ... my other stream (KLV data) is very infrequent (1 packet/sec) and it just writes at the PTS of last video frame. I hope that'll work
[00:10:58 CEST] <ac_slater_> as in, the streams sync on the video clocks. Since it's not a physical problem (like audio), I think it'll be ok
[00:11:10 CEST] <Mavrik> yeah, you probably shouldn't use interleaved call then
[00:11:36 CEST] <Mavrik> otherwise it might happen that the muxer will wait for the KLV packets and will start writing video out in bursts after each KLV packet ;)
[00:12:31 CEST] <ac_slater_> yea .. I dont think I want that. I want everything to be as responsive as possible
[00:12:39 CEST] <ac_slater_> as in, no hidden latency
[00:12:47 CEST] <ac_slater_> I really appreciate your help!
[00:39:20 CEST] <t4nk627> Hi Guys. I have a question which I hope someone can help me with.
[00:41:20 CEST] <t4nk627> I am using libavcodec to encode and store video frames on local disk. The problem is that AVCodecContext.time_base.den doesnt accept all values. If I give a value of 18 for example, the function avcodec_open2 return -1 (an error)
[00:41:31 CEST] <t4nk627> If I use values like 15 or 25, it works fine and return 0.
[00:41:37 CEST] <t4nk627> Anyone has any idea whats going on?
[00:42:13 CEST] <t4nk627> How can I check what the actual error is when I call avcodec_open2
[00:42:18 CEST] <t4nk627> and it returns -1
[00:43:44 CEST] <t4nk627> Here is the code.
[00:44:02 CEST] <t4nk627>     mCodecContext->bit_rate = 5000000;     mCodecContext->width = size.width();     mCodecContext->height = size.height();     mCodecContext->pix_fmt = PIX_FMT_YUV420P;     mCodecContext->time_base.num = 1;     mCodecContext->time_base.den = frameRate;     mCodecContext->gop_size = 10;     mCodecContext->max_b_frames = 1;      // trick for 15 FPS video //    if (mCodecContext->time_base.den == 15) { //        mCodecContext->time_base
[00:44:24 CEST] <t4nk627> int ret = avcodec_open2(mCodecContext, mCodec, NULL);
[01:04:25 CEST] <ac_slater_> t4nk627: paste the code to a paste site
[01:35:47 CEST] <t4nk627> Hi. I am trying avcodec_open2 with mCodecContext->time_base.den = 10 and it is giving an error (-1). Anyone has any idea whats going on+
[01:35:48 CEST] <t4nk627> ?
[01:36:02 CEST] <t4nk627> For other values (30, 50) it works fine.
[03:43:58 CEST] <Infiltrator> Running ffmpeg again with strace.
[03:49:32 CEST] <Infiltrator> And this time, no problems... of course...
[03:49:59 CEST] <c_14> It would be boring otherwise.
[03:50:50 CEST] <Infiltrator> Indeed.
[03:51:30 CEST] <Infiltrator> But it makes me think that I'm crazy.
[03:52:34 CEST] <Infiltrator> Well, it's about 17% of the way through.
[04:01:00 CEST] <Infiltrator> So, good news: my system didn't hang this time.
[04:01:49 CEST] <Infiltrator> And ffmpeg became a zombie this time.  It didn't last time because I didn't actually kill it properly.
[04:02:08 CEST] <Infiltrator> (I tried to do kill -KILL -- -892)
[04:04:01 CEST] <Infiltrator> Shit.  Spoke too soon.
[04:04:04 CEST] <Infiltrator> It's dying again.
[04:11:30 CEST] <Infiltrator> In case anybody said anything, I didn't receive any messages.
[04:12:10 CEST] <Infiltrator> The last thing which strace showed before ffmpeg froze was a futex.
[04:12:47 CEST] <Infiltrator> Then I killed ffmpeg, and it became a zombie, and 16 out of 17 threads died; but that one was left.
[04:13:32 CEST] <Infiltrator> Load stayed just below 7; didn't get too high; and CPU time was split about 30/70 between sys and wa.
[04:24:59 CEST] <c_14> What were the last couple lines of the strace?
[04:25:18 CEST] <c_14> Also, are you spawning ffmpeg in a shell?
[06:39:49 CEST] <roboman2444> is there an artificial limit of 30 fps in either nvenc or x11cap?
[06:40:06 CEST] <roboman2444> even if i try to encode at 60fps, it never goes above ~30
[06:40:19 CEST] <roboman2444> nvidia panel says the video engine isnt at full usage either
[06:40:29 CEST] <roboman2444> latest .run from nvidia site
[06:40:33 CEST] <roboman2444> latest ffmpeg git
[07:32:34 CEST] <anshul> how to compile ffmpeg with gprof
[07:53:02 CEST] <mattfoo> i'm experiencing a playback problem when trying to play an x264 encoded stream in flowplayer (flash) when using intra-refresh=1. It's weird. If the player is open before I start streaming via ffmpeg it works. It doesn't work if I'm already streaming and then connect with the player. I'm guessing it might have something to do with no keyframes? Ideas?
[08:26:57 CEST] <anshul> to compile ffmpeg with gprog i am configuring with ./configure --disable-optimizations --extra-cflags=-pg --extra-ldflags=-pg
[08:27:08 CEST] <anshul> is something more needed to do so
[11:05:01 CEST] <RahulAN> Hii all
[11:05:38 CEST] <RahulAN> i tried avconv -video_size 1920x1080 -framerate 30 -f x11grab -i :0.0 -c:v libx264 -qp 0 -preset ultrafast -profile:v high444 ~/Videos/tesseract.mkv to capture screen, but it is not capturing my game.
[11:05:42 CEST] <RahulAN> why so??
[11:10:56 CEST] <BtbN> avconc is not ffmpeg.
[11:13:30 CEST] <RahulAN> BtbN, but when i tried with ffmpeg it won't work
[11:17:36 CEST] <t4nk784> Hi. Does any one knows the allowed values of AVCodecContext time_base.den? avcodec_open2() returns an error when I use 18 for time_base.den. However, it works fine with values like 25, 50.
[11:18:39 CEST] <Mavrik> t4nk784, that depends on the codec
[11:18:51 CEST] <Mavrik> and container too
[11:18:57 CEST] <t4nk784> I am using CODEC_ID_MPEG1VIDEO
[11:33:37 CEST] <Mavrik> why.
[11:35:23 CEST] <Mavrik> t4nk784, MPEG-1 does not support 18fps and need timebase to be 1/fps
[11:35:45 CEST] <t4nk784> Because I want to store the output video as .mpg.
[11:35:57 CEST] <t4nk784> Sorry if it sounds stupid but I am quite new to video encoding.
[11:36:38 CEST] <t4nk784> Can I encode the video with variable frame rate?
[11:36:42 CEST] <Mavrik> not to MPEG-1.
[11:36:49 CEST] <Mavrik> MPEG-1 is a video format obsolete for more than 10 years now
[11:36:54 CEST] <Mavrik> it's a very strange choice.
[11:37:06 CEST] <t4nk784> Which choice would you recommend?
[11:37:34 CEST] <Mavrik> Which formats do players which will read that video support?
[11:38:01 CEST] <t4nk784> I am using VLC to play the output vidoe.
[11:38:04 CEST] <t4nk784> video*
[11:38:57 CEST] <Mavrik> uhhuh
[11:39:06 CEST] <t4nk784> Can I encode the video as .avi with libavcodec?
[11:39:08 CEST] <Mavrik> t4nk784, so encode to H.264 in a MP4/MKV container
[11:39:22 CEST] <Mavrik> stop mixing up containers and video codec formats
[11:39:54 CEST] <t4nk784> Thanks Marvik. Can you recommend some documentation where I can find such information?
[11:41:08 CEST] <Mavrik> I dunno, guess buy a book which will tell you about basics of how digital video works?
[11:41:26 CEST] <Mavrik> It's like asking for documentation for general application development :/
[11:42:34 CEST] <t4nk784> I see. What I would like to know is the format-container relationship, as you mentioned earlier.
[11:45:54 CEST] <Mavrik> http://www.pitivi.org/manual/codecscontainers.html ?
[11:46:50 CEST] <t4nk784> Great. Much appreciated. I will give it a good read :)
[11:46:53 CEST] <t4nk784> Thanks again
[13:27:28 CEST] <mvow> Hello. I'm on Ubuntu 14.04 Unity and I had installed ffmpeg from the jon-severinsson's ppa. Now when updating, it seems that that repository is not active anymore. I wonder if by chance anyone can confirm.
[13:28:59 CEST] <mvow> Btw, here is the link: https://launchpad.net/~jon-severinsson/+archive/ffmpeg
[13:39:09 CEST] <mvow> (I'll read the log later, I'm away for a while)
[13:46:10 CEST] <Guest46723> Does anyone know what has happened to the launchpad jon-severinsson ffmpeg repo? Thanks.
[13:49:04 CEST] <BtbN> Looks like it's gone.
[13:50:03 CEST] <Guest46723> Yes, notice as our travis build stopped working with 404. https://launchpad.net/~jon-severinsson/+archive/ffmpeg has gone completly.
[14:03:13 CEST] <Ders> Hi. Can anybody tell me why the colormatrix filter is not in my ffmpeg executable? Do I need to add something to the compilation?
[14:07:59 CEST] <relaxed> Ders: compile the latest source from git or use http://johnvansickle.com/ffmpeg/
[14:09:32 CEST] <Ders> so it might be that I have a version that just doesn't have it? I'm currently compiling with only the LGPL licensed stuff. Don't know if it's included in one of the GPL options or not
[14:11:06 CEST] <relaxed> run configure with --enable-gpl and without, then check configure's output to see if that's the case.
[14:16:05 CEST] <Ders> hmm... It seems to be something with my compilation. I'm going to check that. It didn't solve the desaturation in the output though. (I thought it would)
[14:16:27 CEST] <Ders> I have RGBA input to yuv420p output so I tried this: -vf colormatrix=bt601:smpte240m
[15:12:58 CEST] <seasc> Heyas, to build ffmpeg with --enable-libv4l2, do i really have to 'tail-in' xorg, udev, mako, phyton (evnethough its already installed) just to build mesa and libdrm... and not sure what else is yet to add up too, which are required for 4vl?
[15:22:58 CEST] <zevarito> if I encode from an URL like this ffmpeg -i https://someplace.com/406285957898944640.webm -c:v h264 out.mp4 is the temp file deleted after convert ends ?
[15:31:01 CEST] <t4nk567> Does anyone know how can I check which configuration options were used which compiling ffmpeg from executable?
[15:38:35 CEST] <BtbN> Read the output from it.
[15:41:54 CEST] <zevarito> t4nk567: run ffmpeg and it will tell you what was enabled/disabled at compiling time
[15:56:01 CEST] <seasc> zevarito, if it generates a file like ffmpeg-SOMESTRING.log, or if you talk about the out.mp4, then no, it should not
[16:05:10 CEST] <zevarito> seasc: so you mean I should handle deletion of temporary file by my own ?
[16:08:56 CEST] <seasc> zevarito, after ffmpeg is done, yes
[16:51:24 CEST] <Raz-X_> hi everyone
[16:52:12 CEST] <Raz-X_> i have to read a h264 stream (over udp multicast), transcode it in MJPEG, and then restream it on http
[16:52:23 CEST] <Raz-X_> is ffmpeg able to do this
[16:52:34 CEST] <Raz-X_> or do i have to install an ffserver too?
[17:56:37 CEST] <codeX_SORA> Hi ppl
[17:57:11 CEST] <codeX_SORA> what's the most besic way to build ffmpeg
[17:57:30 CEST] <IlIlIlIlIlIlI> codeX_SORA: on a debian?
[17:57:43 CEST] <codeX_SORA> yes..
[17:58:00 CEST] <IlIlIlIlIlIlI> codeX_SORA: apt-get --compile source ffmpeg
[17:58:11 CEST] <IlIlIlIlIlIlI> after you add sid repos
[17:58:42 CEST] <IlIlIlIlIlIlI> sid deb-src repos*
[17:59:39 CEST] <codeX_SORA> thanks just downloading
[17:59:46 CEST] <codeX_SORA> 1st
[18:01:37 CEST] <codeX_SORA> i did build ffmpeg 1.0 last time but looks like alot of changes made since
[18:23:41 CEST] <tibbs|w> Hey, folks, I was hoping to get a hint.  I have two videos, generated by different models of Axis security cameras.  Both have been converted from mkv to mp4 with -vcodec copy.  One plays in firefox,  the other doesn't, complaining "Video can't be played because the file is corrupt."
[18:23:56 CEST] <tibbs|w> ffprobe output for both videos is at http://fpaste.org/206004/90529414/
[18:24:15 CEST] <tibbs|w> The first video is the one that won't play.
[18:24:46 CEST] <tibbs|w> ffplay on the first one complains "swscaler @ 0x7fae7c4bfe60] deprecated pixel format used, make sure you did set range correctly", otherwise it plays both fine.
[18:26:30 CEST] <tibbs|w> Besides resolution and aspect ratio, the only difference seems to be that the broken one has "yuvj420p" and the good one has "yuv420p" (no 'j').
[18:26:57 CEST] <tibbs|w> Is it possible to use ffmpeg to change the first one to yuv420p, so I can see if that's really the problem?
[18:28:47 CEST] <tibbs|w> Or can anyone spot any other reason the first video might not play?  ffmpeg 2.4.7, BTW.
[18:32:27 CEST] <tibbs|w> I see old bug reports about chrome not being able to play yuvj420p videos but nothing about firefox.
[18:45:00 CEST] <tibbs|w> Oh, nice, firefox on windows will play it; it must be the free h264 library that they use on linux.  Crap.  So transcoding it seems to be my only option, except that I'm too dumb to figure out how to do that.
[18:46:43 CEST] <tibbs|w> https://ffmpeg.org/pipermail/ffmpeg-user/2013-February/013437.html says that to do this without transcoding would require a bitstream filter, but I don't know if anyone  has written one in the two years since that message was posted.
[19:12:45 CEST] <llogan> tibbs|w: i don't think there is one. a list of "documented" bsf: http://ffmpeg.org/ffmpeg-bitstream-filters.html
[19:15:02 CEST] <tibbs|w> I see something about a patched gpac that will just switch the flag off without re-encoding.
[19:15:28 CEST] <tibbs|w> I don't particularly care about the contrast as long as the videos are still viewable.
[19:16:27 CEST] <tibbs|w> I would prefer not to reencode, though, because of the CPU requirement.
[19:17:38 CEST] <llogan> you could make a feature request for such a bsf on the bug tracker.
[19:18:02 CEST] <tibbs|w> I suppose, though at this point I don't really have enough knowledge to even know what to ask for.
[19:18:28 CEST] <tibbs|w> Heck, I don't even know if the pixel format is the problem (or if "pixel format" is really the right phrase to use).
[19:18:38 CEST] <tibbs|w> But all signs point to that right now, at least.
[19:25:19 CEST] <llogan> you can make a test encode to see if that is the issue: ffmpeg -f lavfi -i testsrc=d=30,format=yuv420p -c:v libx264 -movflags +faststart yuv420p.mp4
[19:25:24 CEST] <llogan> then another one with the j
[19:25:40 CEST] <llogan> then attempt to play each file
[19:27:41 CEST] <kepstin-laptop> on linux, firefox should be using a system gstreamer decoder to handle html5 h264 video in most cases, not the openh264.
[19:28:01 CEST] <kepstin-laptop> (since openh264 only does baseline profile, it's not useful for the majority of web video)
[19:32:26 CEST] <tibbs|w> Hmm, that plays.
[19:32:57 CEST] <llogan> the one with yuvj420p plays?
[19:33:10 CEST] <tibbs|w> Oh, sorry, didn't see the second line of your comment.
[19:33:19 CEST] <llogan> i expected the first one to play
[19:33:34 CEST] <tibbs|w> Yeah, the second one doesn't play.
[19:33:45 CEST] <llogan> i guess that somewhat narrows it down
[19:33:58 CEST] <tibbs|w> Yeah, at least I can be sure that's the problem.
[19:34:18 CEST] <tibbs|w> I guess for now I need to figure out how to re-encode from one to the other until I can find a better solution.
[19:34:58 CEST] <llogan> what about your gpac lead? (not that i use gpac so you're on your own there)
[19:35:20 CEST] <tibbs|w> There's an old patch on github; I'd have to play with it for now.
[19:35:47 CEST] <tibbs|w> It's just a flag in the header as I understand things; flipping it shouldn't screw up the video but might leave the contrast a bit weird.
[19:36:26 CEST] <tibbs|w> As far as I can tell, that gpac patch didn't make it upstream, so I'd have to do something locally.  Which isn't hard, assuming the patch still applies.
[19:37:07 CEST] <tibbs|w> But now I've found my camera supports both Main and Baseline H.264 profiles, so I need to play with that.
[19:38:10 CEST] <llogan> you'll only need baseline if your target devices/decoders can't support main or higher.
[19:38:44 CEST] <tibbs|w> Still doesn't appear to play if I select baseline.
[19:38:59 CEST] <kepstin-laptop> on all the devices i've tested, firefox can play high just fine, the profile's probably not the issue.
[19:39:38 CEST] <tibbs|w> Yeah, it doesn't appear to make much difference.
[19:40:17 CEST] <tibbs|w> Was worth a try, though.
[19:43:20 CEST] <tibbs|w> To save me an arduous trip through the docs, could someone possibly suggest how I'd actually re-encode from 'j' to 'not-j'?
[19:44:31 CEST] <llogan> ffmpeg -i input -pix_fmt yuv420p -c:a copy output
[19:44:59 CEST] <llogan> oh, you don't have audio, so you can omit -c:a copy. i forgot to add "-movflags +faststart"
[19:47:54 CEST] <tibbs|w> Yeah, no audio.
[19:48:18 CEST] <tibbs|w> Weird; I disabled openh264 and made sure gstreamer-ffmpeg was installed.
[19:48:40 CEST] <tibbs|w> I can still play 'non-j' videos but not 'j' ones.
[19:49:14 CEST] <tibbs|w> So I guess it's not openh264 either.  Would be nice if firefox told me what it was doing.
[19:49:20 CEST] <kepstin-laptop> note that on recent linux distros, firefox uses gstreamer-1.0, which uses the gstreamer-libav package, not gstreamer-ffmpeg
[19:51:46 CEST] <tibbs|w> Well, I installed that as well and still the same behavior.
[19:52:04 CEST] <tibbs|w> Guess I need to find a firefox support channel.
[19:52:14 CEST] <kepstin-laptop> it should be the same behavious, because that's what it should have been using all along...
[19:52:37 CEST] <kepstin-laptop> firefox does *not* use openh264 to decode videos served via the html5 video element on most oses.
[19:53:29 CEST] <tibbs|w> Well, I didn't have gstreamer1-libav installed at all.  So I guess I don't know what it's using.  But running firefox in a terminal I do get some stuff that sort of looks like ffmpeg or libav output.
[19:54:00 CEST] <tibbs|w> http://fpaste.org/206054/27910836/
[19:54:15 CEST] <tibbs|w> decode_slice_header error   no frame!
[19:55:19 CEST] <tibbs|w> I get the exact thing trying to play that testsrc file generated earlier.
[19:56:57 CEST] <tibbs|w> I don't get it when running ffplay on the same file.
[19:58:11 CEST] <kepstin-laptop> i wonder if it might be an issue with the mp4 demuxer they're using. I don't think they're using libavformat for that.
[19:58:35 CEST] <tibbs|w> That indeed could be.  Or maybe there's just some other random package I need to have installed.
[19:58:55 CEST] <kepstin-laptop> can you try just launching "gst-play-1.0" (or 0.10, if you have that) on your file?
[19:59:09 CEST] <kepstin-laptop> if they're using the gstreamer mp4 demuxer, that should give the same error
[20:00:23 CEST] <tibbs|w> gst-play-1.0 does indeed play the file fine.
[20:04:27 CEST] <tibbs|w> So, yeah, maybe this is just a firefox thing, but a linux-specific firefox thing.
[20:06:15 CEST] <tibbs|w> Well, I'm off to file bugs.  Thanks for the assistance.  If you have any other ideas I'd be happy to hear them.
[20:19:30 CEST] <ac_slater_> hey all. With libavformat, how can I create a codec context for h264? As in, I have some already encoded h264 data I want to mux... I just need to create a stream around it.
[20:29:03 CEST] <llogan> ac_slater_: did you see any of the files in doc/examples? might be helpful.
[20:30:42 CEST] <ac_slater_> llogan: I was missing a point. I figured it out
[20:31:13 CEST] <ac_slater_> llogan: I was thinking I still has to do `avcodec_open2()` eventhough I just needed to fill a AVCodecContext
[20:31:18 CEST] <ac_slater_> s/has/had
[20:31:34 CEST] <llogan> ok. you know more aobut the libraries than i do.
[20:59:24 CEST] <tibbs|w> For anyone interested, this was some random firefox setting.
[21:00:08 CEST] <tibbs|w> media.fragmented-mp4.exposed, or one of the media ones around that.  I have no idea why, or even how that setting was changed.
[21:00:46 CEST] <tibbs|w> Anyway, thanks for all of the hints.  Now I can get back to work.
[21:02:35 CEST] <tibbs|w> Really, really should have just started firefox with a fresh profile first.
[21:06:51 CEST] <selsta> any way to force ffmpeg to demux data even if the result will be broken?
[21:07:15 CEST] <selsta> ffmpeg -i 2.ts -map 0:0 -c copy out.aac      currently produces no file, but id like to get the audio stream out of it..
[21:45:41 CEST] <selsta> llogan: http://sprunge.us/YHOh
[21:56:27 CEST] <llogan> selsta: can you provide the input file?
[21:57:11 CEST] <seasc> Trying to compile libxml for fontconfig, for v4l2, but it faills on including the python.h even when i pass --includedir=/path/to/python.h
[21:58:02 CEST] <seasc> http://pastebin.com/kMrWQHaD
[22:10:00 CEST] <llogan> seasc: try #xml or their mailing list
[22:17:03 CEST] <selsta> llogan: http://a.pomf.se/fuaeki.ts
[22:18:01 CEST] <selsta> llogan: this file contains encrypted audio. i have to demux the audio, decrypt it and remux it back together
[22:19:00 CEST] <selsta> but i cant demux it because ffmpeg cant read the audio (which is expected). i would hope there might be some ignore errors switch or something like that
[22:44:02 CEST] <tlhiv_laptop> is it no longer possible to run ffserver in daemon mode?
[22:44:07 CEST] <tlhiv_laptop> i want to run it in the background
[22:45:15 CEST] <DJJeff> I tried to apt-get install ffmpeg and got some wierd error
[22:45:24 CEST] <DJJeff> is ffmpeg not in ubuntu repo?
[22:45:35 CEST] <BtbN> Ubuntu has libav.
[22:46:27 CEST] <DJJeff> ffmpeg returns to ubuntu in 15.04?
[22:46:33 CEST] <DJJeff> just saw that in google
[22:46:41 CEST] <BtbN> no idea, but the ppa is gone for some reason
[22:47:41 CEST] <DJJeff> how does libav compare to ffmpeg
[22:48:28 CEST] <DJJeff> oh its called avconv
[22:48:49 CEST] <DJJeff> hrmmmmmm both are missing from repos
[22:50:12 CEST] <BtbN> avconv is an entirely seperate project
[22:55:08 CEST] <DJJeff> deb http://ppa.launchpad.net/mc3man/trusty-media/ubuntu trusty main
[22:55:19 CEST] <DJJeff> should I try this?
[23:18:56 CEST] <DJJeff> ok I did and I am trying to extract audio from a .swf and got this
[23:18:57 CEST] <DJJeff> http://paste.ubuntu.com/10720729/
[23:21:46 CEST] <BtbN> swf is a flash applet, not something you can extract an audio track from
[23:22:01 CEST] <BtbN> Wouldn't be surprised of there are some tools that still do that though
