[00:22] <sputnick> hi there
[00:23] <sputnick> is there any way to have the ffmpef version in a portable way ? archlinux is version 20120127-3 and ubuntu 0.6
[00:23] <sputnick> *ffmpeg*
[00:28] <sacarasc> sputnick: You could statically compile it, then you could move the binary around to different OS's and not worry about dependencies.
[00:29] <sputnick> sacarasc: I ask that because an application need to check the version to change flags on the fly.
[00:29] <sputnick> are you french sacarasc ?
[00:29] <sacarasc> No.
[00:29] <sputnick> ok ;)
[00:29] <sacarasc> I think you can also have runtime CPU detection...
[00:30] <sputnick> My question is a developer point of view
[00:32] <sputnick> He, by flag, I don't talk about ./configure :D
[00:32] <sputnick> I talk about --optA --optB --optC
[00:32] <sputnick> ffmpeg --optA --optB --optC
[03:46] <m0> Hello, is ther a way to know what svn revision 25620 is in git?
[03:49] <m0> USually when you do a git svn it stores the revision in the commit, but when searching for "git log -g --grep=25620" it returns nothing
[03:55] <m0> I guess this is sufficient: svn info -r 25620, to get the date, then git log --since =date
[12:47] <burek> hm, how can i select font to be used in ass subtitle, using ffmpeg -vf ass=sub.ass
[12:48] <burek> whichever font I put in the ass file, I get the ffmpeg error: fontconfig: Selected font is not the requested one: 'DejaVu Sans Bold' != 'Arial'
[12:48] <burek> it always selects DejaVu Sans Bold
[12:48] <burek> -error +warning
[12:56] <burek> ok, I guess the solution was apt-cache search ttf-  :)
[13:40] <rainmaker1> Hi, when I try to stream to local multicast address using sap as output I got floating point exception error
[13:40] <rainmaker1> when my output is flv it works just right
[13:41] <rainmaker1> if someone want to look at here is pastebin http://pastebin.com/216iaGPE
[13:54] <rainmaker1> heh.. latest ffmpeg woks..
[17:01] <Kasper^> hi, is there any updated tutorial on libavcodec on how to simply read a frame from a video ?
[17:02] <Kasper^> I only found examples which use deprecated functions and I am complete noob with ffmpeg
[17:14] <Hacker-CB> av_read_frame
[17:17] <Kasper^> Hacker-CB: well, I've this seems to be the most recent basic example I could find http://web.me.com/dhoerl/Home/Tech_Blog/Entries/2009/1/22_Revised_avcodec_sample.c_files/avcodec_sample.0.5.0.c
[17:18] <Kasper^> but I get many errors on compile with mingw, like 'CODEC_TYPE_VIDEO' undeclared
[17:20] <Hacker-CB> sorry, i don't know any experience with mingw.
[17:20] <Hacker-CB> I'm working under linux
[17:21] <Hacker-CB> try to modify
[17:21] <Hacker-CB> extern "C" {
[17:21] <Hacker-CB> #include <libavcodec/avcodec.h>
[17:21] <Hacker-CB> #include <libavformat/avformat.h>
[17:21] <Hacker-CB> #include <libswscale/swscale.h>
[17:21] <Hacker-CB> }
[17:21] <Kasper^> well, I could try to compile it under linux, that's not a problem
[17:21] <Kasper^> problem is the code is using many deprecated functions
[17:22] <Kasper^> from what I've read ffmpeg changed a bit in the past 2 years
[17:33] <stongo> is it possible to install ffmpeg 7.x+ on centos 6 64bit?
[17:33] <stongo> yum only installs up to 6.5.x
[17:34] <stongo> and everytime I try to compile 7+ I get this error "/usr/bin/ld: /usr/local/lib/libvpx.a(vpx_codec.c.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC"
[17:34] <stongo> I am setting the flags -fPIC in ./configure
[17:34] <stongo> and have libtool installed
[18:30] <teratorn> yeah, libvpx inline assembler doesn't like being built and linked statically
[21:10] <fling> hello
[21:11] <fling> how to sync video/sound if i join multiple files? :[
[21:13] <Goffredo> look at this http://stackoverflow.com/questions/1329333/how-can-i-add-audio-mp3-to-a-flv-just-video-with-ffmpeg
[21:13] <Goffredo> just duckduckgoedit
[21:23] <sweb> how can i get configure of current installation of ffmpeg
[21:24] <Goffredo> ffmpeg -version?
[21:38] <sweb> how can i configure ffmpeg with full format support
[21:42] <sweb> i have a problem installing Opencv and i believe it has something to do with ffmpeg can anyone help please?
[21:42] <Goffredo> errors?
[21:45] <sweb> i think i have to change CODEC_TYPE_VIDEO to AVMEDIA_TYPE_VIDEO but don't know how...
[21:45] <cbsrobot> replace it to AV_*
[21:47] <sweb> http://pastie.org/3610750
[21:47] <sweb> Goffredo, cbsrobot: ^
[21:48] <cbsrobot> sweb: be more verbose
[21:50] <sweb> cbsrobot: updated http://pastie.org/3610750
[22:54] <daniels89> hi
[22:54] <daniels89> has FFmpeg accepted for summer of code?
[22:54] <daniels89> +been
[22:55] <daniels89> I don't see it on http://www.google-melange.com/gsoc/accepted_orgs/google/gsoc2012
[22:57] <sacarasc> Wouldn't that be a big clue? :p
[23:01] <daniels89> I don't think so, the list is not complete. projects have fill out a profile. the list is slowly growing now at 115 from 180 projects
