[00:03] <cbreak> maujhsn: do you know how to compile a program? [00:05] <maujhsn> cbreak I am using a liveUSB! [00:05] <cbreak> then it's probably not for you :) [00:06] <maujhsn> Do not know how to compile from liveUSB [00:06] <maujhsn> bullshit! [00:17] <teratorn> by default do timestamps on audio packets refer to the start or the end of the samples? [00:19] <cbreak> I always expected it to mean the start [00:21] <teratorn> that's my naive expectation too, but I'm looking at a system that captures audio in over half-second intervals, then encodes it using a timestamp generated from current system time [00:21] <teratorn> so I'm expect it to be out of sync with the video, but it's not [01:07] <Rango212> can anyone tell me what -strict experimental does? [02:15] <desti> do i need to add some special option for vorbis? copied a vorbis sound out of a mkv video and now i can't scoll in the audio file [02:21] <hallowicked> anybody know if its possible to output the logfile as a .xml [02:59] <Arthur_D> I've got a file with slightly out-of-sync audio. How do I go about correcting it? [03:20] <Arthur_D> found the solution :) [03:24] <hallowicked> howd u do it Arthur_D [03:25] <Arthur_D> well, it was the solution to my problem, so not sure if it applies ;) [03:33] <hallowicked> heh so u figure it out and are asked how u did and dont wanna help others lol [03:41] <Arthur_D> no, that was not what I meant. I saw you had asked a question, and my wording could be misunderstood to the point that you thought I found a solution to your problem, when I only found a solution to my own [03:42] <Arthur_D> anyway, I used ffmpeg -itsoffset 00:00:00.6 -i inputfile -vcodec copy -acodec ac3 outputfile [03:43] <Arthur_D> as per this how-to: http://howto-pages.org/ffmpeg/#delay [03:58] <hallowicked> ahh cool [03:58] <hallowicked> ya ive had sync issues also [03:58] <hallowicked> especially after using avidemux to edit commercials [04:00] <Arthur_D> haha [04:01] <hallowicked> u know any .tcl by chance hehe [04:01] <Arthur_D> funnily enough, I needed to resync after using avidemux [04:01] <hallowicked> ya avidemux sucks for editing [04:01] <hallowicked> always throws my stuff off [04:01] <hallowicked> even when i copy copy [04:02] <Arthur_D> it was a disappointment yeah. Especially since it seemed to be very good for its purpose in all other aspects [04:02] <hallowicked> what type of videos do u encode? [04:04] <Arthur_D> well, for the time being, I'm trying to author a DVD, so I go for as lossless as possible since the DVD authoring program often needs to reencode at the end [04:05] <hallowicked> just a normal dvd? [04:05] <hallowicked> i do live tv and dvds [04:06] <piercedwater> I switched from HandBrakeCLI, where I was getting 100+ fps and now when I use ffmpeg I am only getting ~15fps. I assume it is because it is not using all of my cores. My command is 'ffmpeg -threads 4 -i <path> <output>.mp4' [04:06] <piercedwater> Would be greatful for some help [04:06] <hallowicked> put threads at the end [04:07] <hallowicked> ffmpeg -i infile options -threads outfile [04:07] <hallowicked> and checkyour task manager u should be using 100% pc or close to it [04:07] <piercedwater> didn't make a dufferebce [04:07] <piercedwater> difference [04:07] <hallowicked> if u do -threads 0 [04:07] <hallowicked> try -threads 0 [04:08] <piercedwater> still slow [04:08] <piercedwater> im at 50% cpu usage [04:08] <hallowicked> hmm [04:08] <piercedwater> when it's running [04:08] <piercedwater> im on freebsd 9 [04:08] <hallowicked> could u pastebin your output ill take a look see if i notice nething [04:08] <piercedwater> sure [04:08] <hallowicked> kk ill be here when your ready [04:09] <piercedwater> http://dpaste.com/691261/ [04:10] <hallowicked> line 1 [04:10] <hallowicked> -threads 0 [04:10] <hallowicked> put before output file [04:11] <hallowicked> ffmpeg -i infile.mkv -threads 0 outfile.mp4 [04:11] <hallowicked> try that [04:11] <piercedwater> im at about 20 fps [04:12] <hallowicked> ohh [04:12] <hallowicked> fps was yoru question [04:12] <hallowicked> im sorry i misread [04:12] <piercedwater> np [04:12] <hallowicked> i belive to set fps is [04:12] <hallowicked> -r [04:12] <piercedwater> no [04:12] <piercedwater> i mean [04:12] <piercedwater> wait [04:12] <piercedwater> am i being dumb [04:12] <hallowicked> i dunno i may be [04:12] <hallowicked> lol [04:13] <hallowicked> im lost now [04:13] <piercedwater> fps during conversion states how many frames it is converting per second, right [04:13] <hallowicked> i dont think so [04:13] <hallowicked> i could be wrong [04:13] <hallowicked> whats the orginal files fps [04:15] <piercedwater> i believe fps has to do with how fast it is converting. b/c i was getting 100+ in handbrakecli [06:50] <nutron> Oh hello! [06:52] <nutron> Noob, but I saw an option to convert from flac to mp3 with the -ab option to set the bitrate, I cannot find that option in the man page. What is the correct option to set the converted bitrate? I have this so far: ffmpeg -v quiet -i file.flac file.mp3. How can I ask for 192kbps? [06:56] <grepper> nutron: I think it is changed to -b:a now. Search for -b:a in the manpage [06:57] <grepper> -b:a = audio, -b:v = video [06:58] <nutron> grepper: ahh thanks [07:00] <grepper> np [14:33] <undercash> hello, i m trying to stream on ubuntu using vlc, and i would like to use ffmpeg as video encoder.

[20:06] <undercash> what is wrong? [20:10] <Mavrik> *shrug* [20:10] <Mavrik> undercash, you should probably ask VLC devs what do they expect in the ffmpeg build they're using [20:10] <Mavrik> or your library devb [20:10] <Mavrik> it's hard to know what a 3rd party software means by "crippled ffmpeg" [20:11] <undercash> no idea, they just say it has nothing to do with vlc ;) [20:11] <undercash> and you say the same ;) [20:11] <Mavrik> undercash, well... we can help if you can find out what's missing [20:11] <Mavrik> "FFmpeg is crippled" doesn't say much :P [20:11] <undercash> avcodec encoder error: cannot find encoder H264 - MPEG-4 AVC (part 10) [20:11] <undercash> *** Your FFMPEG installation is crippled. *** [20:11] <undercash> *** Please check with your FFMPEG packager. *** [20:11] <Mavrik> mhm [20:11] <undercash> *** This is NOT a VLC media player issue. *** [20:11] <undercash> i know [20:11] <Mavrik> I see. [20:11] <Mavrik> undercash, that could just be a version mismatch [20:11] <Mavrik> which ffmpeg do you have? [20:12] <sacarasc> undercash: There's a guide in the topic for compiling your own ffmpeg on Ubuntu. And that one won't be crippled. [20:12] <undercash> http://pastebin.com/SxijajxS [20:12] <undercash> it s not crippled [20:13] <undercash> i use it for video encoding [20:13] <undercash> no problem [20:13] <undercash> but when i specify " venc=ffmpeg{blabla} in the vlc transcoding line it returns this error message [20:16] <Mavrik> hmm [20:42] <maujhsn> I have an mplayer install issue...."Help" http://pastebin.com/E5y7yQ63 [20:43] <Mavrik> Your repositories/repository configurations are broken. That's not an ffmpeg issue. [20:44] <maujhsn> mavrik...OK [20:46] <maujhsn> Mavrik Can you solve this issue? http://pastebin.com/8GhUXipq [20:48] <Mavrik> maujhsn, yeah, your ffmpeg is really old and doesn't have libx264 compiled in [20:49] <Mavrik> that's why it says "can't find encoder libx264" [20:49] <Mavrik> maujhsn, if you're on ubuntu, follow this guide: [20:49] <Mavrik> http://bit.ly/3xSE5 [20:57] <maujhsn> Mavrik "That old post still works? [21:11] <maujhsn> Mavrik "How do you know if the conventions to that old post still work?" [21:18] <maujhsn> Can anybody solve this issue? "http://pastebin.com/8GhUXipq" I am skeptical about Mavrik's take on this issue! [21:19] <apoc> does ffmpeg somehow support f4v / f4a ? and is it possible to live transcode h264 into an flv container? [21:21] <maujhsn> apoc You might find the answer to your question in /usr/doc/ffmpeg [21:22] <apoc> not a word about f4a/v [21:22] <apoc> but that doesn't mean much, the documentation sucks [21:23] <maujhsn> apoc OK [21:27] <maujhsn> Here are my installed packages for libx264...now how do I compile it? "http://pastebin.com/1ppg9JmB". [21:35] <Mavrik> maujhsn, there's nothing old about it. You have all the instructions you need right where I pointed you. [21:35] <Mavrik> Your "scepticism" doesn't change a thing. [21:35] <Mavrik> apoc, hmm [21:35] <Mavrik> apoc, flv is supported for demuxing and muxing [21:36] <maujhsn> Mavrik...I know I have tried your patience...Please accept my apology..OK? [21:36] <maujhsn> I will give it a shot! [22:03] <undercash> One of the most important parts of the preparation for compiling vlc-git is preparing a recent version of libavcodec for vlc usage. The following accomplishes this with a local, not system installation of FFmpeg and is again a single command: [22:04] <undercash> so what i should have 2 ffmpeg on my system [22:04] <undercash> doesnt seem recommended [22:06] <maujhsn> Mavrik So far it is download is OK accept this: "http://pastebin.com/FAHDQEKF" any suggestions? [22:06] <maujhsn> Mavrik Seven steps were completed. [22:08] <Mavrik> undercash, that depends... because large pieces of Ubuntu are dependant on packaged libav* libraries, local installation is a better choice [22:08] <Mavrik> (even though, I don't have problems running the new version) [22:09] <undercash> i have ffmpeg installed using the usual ffmpeg topic by fakeman [22:09] <undercash> i guess that one is the system one [22:09] <undercash> won't it create some conflict if i install this local version for vlc? [22:09] <Mavrik> undercash, yeah, that overwrites the system version [22:10] <Mavrik> undercash, um, basically, you're not supposed to do checkinstall [22:10] <Mavrik> but you'll have to pass "--prefix=<install folder>" for configure [22:10] <Mavrik> and run VLC with LD_LIBRARY_PATH that shows to the custom built libraries [22:10] <undercash> he described this in the second code box http://ubuntuforums.org/showthread.php?t=1398119 [22:11] <undercash> third [22:11] <maujhsn> Mavrik Do I just leave things alone now? Or do I execute step number 9? "Updating FFmpeg and x264". [22:12] <Mavrik> maujhsn, you didn't follow all the instructions and your checkinstall fails [22:12] <Mavrik> why aren't you reading your output? [22:14] <maujhsn> Mavrik Do I need to start from the beginning again? [22:17] <undercash> can't be wrong [22:20] <maujhsn> Mavrik Check this out: http://pastebin.com/FgNaiKrp [22:21] <Mavrik> "ERROR: libmp3lame >= 3.98.3 not found" [22:21] <Mavrik> Read. Error.
