[00:13] <videoman> Install ffmpeg according to https://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide
[00:13] <videoman> On Ubuntu 13 keep getting The program 'ffmpeg' is currently not installed.
[00:15] <elkng> I have file "file.swf", these are its parameters: http://sprunge.us/RPXh, and thats the command I use to convert it to video: "ffmpeg  -i file.swf  -vcodec mpeg4 -vb 1500k   -ab 128 -ar 44100 -ac 2 -acodec libmp3lame -y -f avi file.avi", and thats the output: http://sprunge.us/UegZ, what is wrong with that file or ffmpeg can't convert from *.swf
[00:15] <elkng>  to *.avi ?
[00:21] <sacarasc> elkng: Is it an actual video, or a vector animation?
[00:33] <luisbug> hi has anyone used the dshow capture o windows with logitech c920?
[00:33] <luisbug> (on windows 8 that is...)
[00:34] <llogan> videoman: did you encounter any errors?
[00:36] <videoman> llogan I did not encounter any errors.
[00:36] <llogan> is the ffmpeg binary in ~/bin?
[00:38] <videoman> no it is not
[00:38] <llogan> then something went wrong somewhere. the next step is to determine which step is messed up at.
[00:39] <videoman> ok thanks, I'll try again but it made it through make install
[00:41] <llogan> apparently this VM ubuntu machine is named "cornhole"
[00:42] <llogan> how does anyone get used to Unity?
[01:44] <luisbug> any owner of an logitech c920 that has capture the hardware h264 with it?
[01:48] <videoman> llogan: still trying on Ubuntu 13.04.  Can't run make: Nothing to be done for `all'. Some warnings in running .config but it finished. I've done this several times on earlier versions of Ubuntu, never ran into this
[01:49] <elkng> who run make on ubuntu ?
[01:49] <elkng> pun intended
[01:49] <elkng> got it ?
[02:16] <llogan> videoman: then perhaps configure failed. see the tail of config.log in ~/ffmpeg_sources/ffmpeg/ for a clue
[02:17] <videoman> Thanks llogan, I found the issue.  The binary was put in home/ubuntu/bin instead of /usr/bin
[02:19] <llogan> yes, the guide is designed to place the binary in the user's home to avoid conflict with repository stuff
[02:19] <llogan> (and libraries especially)
[02:19] <llogan> but issuing "ffmpeg" should still use the version in $HOME/bin if all is well with the guide.
[03:22] <narcan> is it possible to use the segmenter feature of ffmpeg to create segments with individual files for audio and video ?
[07:22] <soundz> hello! i just compile ffmpeg using the guide (http://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide) it looked like everything went smooth till it's all done -- bash: ffmpeg: command not found
[07:22] <soundz> i'm on debian 7
[07:25] <klaxa> sounds like the ffmpeg binary is not in your PATH environment variable
[07:27] <soundz> i can't locate the ffmpeg binaries at all lol
[07:28] <klaxa> did you run "make install" ?
[07:28] <soundz> sure
[07:28] <klaxa> did you specify --prefix=/some/dir during ./configure?
[07:29] <soundz> yes ofc
[07:29] <klaxa> did you add that directory to your PATH?
[07:32] <klaxa> soundz?
[07:32] <soundz> sorry, one sec
[07:41] <klaxa> this second is taking to long for me to postpone sleep any further, i suggest you check your $PATH, good night
[07:42] <klaxa> *too long
[07:42] <soundz> the $path is not the problem
[07:42] <soundz> and i'm sorry again
[07:42] <soundz> i'm just trying to trace the problem
[07:42] <soundz> night
[07:43] <klaxa> can you post your $PATH variable?
[07:43] <klaxa> and tell me where you installed ffmpeg?
[07:44] <klaxa> why are you so sure your PATH variable is correct?
[07:44] <klaxa> if the command is not found, there is nothing else that comes to my mind
[07:44] <klaxa> undless you cross compiled for another system, but i don't think you did that if you followed the guide properly
[07:50] <soundz> sorry for my delay again lol
[07:50] <soundz> ffmpeg version git-2013-08-09-18be3fa Copyright (c) 2000-2013 the FFmpeg developers
[07:50] <soundz>   built on Aug  9 2013 07:48:14 with gcc 4.7 (Debian 4.7.2-5)
[07:50] <soundz> i just followed the old guide
[07:50] <soundz> http://web.archive.org/web/20130326055445/https://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide
[07:51] <soundz> mindlessly copy paste everything except the ffmpeg ./configure part
[07:51] <soundz> and it worked great lol
[07:52] <soundz> thanks again
[08:02] <mark4o> soundz: when you followed the current compile guide did it put anything in $HOME/ffmpeg_build?  There should have been a bin directory with ffmpeg in it.
[08:03] <mark4o> or actually it uses $HOME/bin
[08:04] <soundz> it uses ffmpeg_build
[08:04] <mark4o> did you configure with --bindir="$HOME/bin" ?
[08:05] <soundz> it doesn't matter anymore
[08:05] <soundz> i managed to get it working
[08:06] <mark4o> ok, just wanted to find out if there was something that needed to be fixed in the current guide
[08:07] <soundz> i just used the old guide :\ it's idiot proof
[08:08] <mark4o> well some people don't have root and can't install stuff systemwide, so it didn't work for them
[08:08] <soundz> i had to root in current guide
[08:09] <soundz> the yasm part needs root
[08:10] <soundz> especially  the make install
[08:10] <mark4o> that's the old guide; the current guide installs in your home directory
[08:12] <soundz> i had to root in order the compile yasm
[08:12] <soundz> i was getting denies and stuff
[08:12] <soundz> with the new guide
[08:14] <mark4o> I don't know why that would happen; there should be no need for root to compile or install in your home directory
[09:34] <braincracker> hey
[09:34] <braincracker> "intel inside, idiot outside" :)  drawn this in 2005, i see it is quite popular on the net now, they sell t-shirts with this on them  http://tinypic.com/view.php?pic=332lzls&s=5
[10:31] <karlox> hi all thereis a way to drop frame when there are this error: Cannot use next picture in error concealment ?
[12:37] <theodorz> Hi, I'm using the ffmpeg libraries for a audio streaming and playback application. I'm using "avformat_open_input" and then "av_read_frame" to open a remote ogg file. I'm wondering if FFMPEG does any automatic background preloading/buffering the of a remote data? Or should I read as many frame as possible into a temporary buffer to avoid risking audio-playback to starve?
[12:38] <theodorz> And if so, can I configure how much of data is downloaded when calling avformat_open_input?
[13:28] <badcompiler_> qqwhat does --extra-ldflags=somedir actually do when configuing ?
[13:31] <JEEB> that does nothing, -L/some/dir/somwhere/lib adds a directory to the library search path
[13:32] <JEEB> (with --extra-ldflags since -L is a linker flag
[13:33] <badcompiler_> @jeeb, yeah thanks, I don't know why I didn't figure that out, there are so many ffmpeg guides, some of them specify lib dirs, some of them don't. I stupidly assume everytime I compiled something the "system" would magically find what it needs
[13:33] <JEEB> if you poke gcc enough you will see its default include and library search dir paths
[13:33] <JEEB> usually googling for it helps
[13:35] <JEEB> so if you install into those directories, it will be found automagically (caveat: if you compiled as shared, you will have to do ldconfig first, only after that your library will be found)
[13:35] <badcompiler_> yeah thanks, I was trying to build x264-devel and it was not picking up lavf, I realise now if I point it with ldflags=somedir and cflags=somedir it configures with lavf support
[13:37] <badcompiler_> I guess I should really about how compiling works
[13:54] <raduu> hello, would you please help me out with this one: http://stackoverflow.com/questions/18132342/ffmpeg-rtmp-streaming-process-exit
[13:58] <raduu> opening 2 terminals and running ffmpeg with 2 different rtmps, then killing one of them closes the other one also.
[13:58] <raduu> is this expected? can it be avoided?

[15:16] <elkng> is it possible to convert .swf to .avi ?
[15:21] <badcompiler_> trying to build --enable-shared, keep getting  XXXXXX.some.thing  can not be used when making a shared object; recompile with -fPIC
[16:42] <theodorz> Here is a stackoverflow post for my question earlier, if anybody happens to know: http://stackoverflow.com/questions/18120182/ffmpeg-libavformat-internal-buffering
[16:53] <zap0> elkng. swf is vectors in'it ?
[16:55] <elkng> zap0: some of them can be converted, by in my case seem like can't
[17:23] <cheri> hello I have an mpeg file which has mpeg2video codec and ac3 audio and I want to convert it to flv and mp4 in a single ffmpeg command when I do it in two steps everything is fine but when i do it in one step for the mp4 file I get  'moov atom not found'
[17:23] <cheri> can anyone help me with this
[17:24] <cheri> ffmpeg -i test.mpg -y -b 512000 -s 320x240 -ar 22050 -ac 2 -ab 32k /var/www/test/test1.flv -b 512000 -s 320x240 -vcodec libx264 -ar 48000 -r 30000/1001 -acodec libfaac -ac 2 -ab 32k /var/www/test/test1.m4v
[17:29] <elkng> was there alien technology used in ffmpeg ?
[18:07] <Fjorgynn> :)
[18:07] <Fjorgynn> hm
[23:26] <Martijnvdc> hello. is there a way to dynamically change the bitrate of an encoder in ffmpeg?
