[13:52] <durandal_1707> burek: where is list of stuff fflogger know about?
[13:54] <burek> what do you mean
[13:55] <burek> list of commands?
[13:55] <durandal_1707> exactly
[13:55] <burek> well !help should do
[13:55] Action: durandal_1707 feels dumb
[13:55] <burek> you probably blocked noticies
[13:55] <durandal_1707> no, i ignored them
[13:56] <burek> thats what i meant :)
[13:56] <durandal_1707> i expect it to spam here
[13:56] <burek> why
[13:56] <burek> you need the help, not everyone else ^^
[13:57] <someone-noone> hello! I'm developing some format for ffmpeg. How should I specify fps value while demuxing?
[14:00] <cone-93> ffmpeg.git 03Anton Khirnov 07master:9782c778a205: h264: remove silly macros
[14:00] <cone-93> ffmpeg.git 03Anton Khirnov 07master:c5fcdb440237: error_resilience: remove a useless if() and FIXME
[14:00] <cone-93> ffmpeg.git 03Michael Niedermayer 07master:7f23b2a9d0da: Merge commit 'c5fcdb440237f06f6c954185ab60970cabf786a2'
[14:00] <cone-93> ffmpeg.git 03Michael Niedermayer 07master:b8d6108cfcb8: error_resilience: assert that unsupported B frame interpolation isnt used with h264
[14:00] <michaelni> someone-noone, if fps matches timebase setting the timebase alone should work fine see avpriv_set_pts_info
[14:01] <Compn> someone-noone : what format are you working on? :)
[14:02] <durandal_1707> funny but ffplay eats 1-3 last lines of image if height is not multiply of 4
[14:03] <Compn> is it sdl bug ?
[14:04] <someone-noone> michaelni, actually I don't understand how avpriv_set_pts_info works(is it just settings time_base?). If I set directly time_base it doesn't work (values are 1 and 24000). If I put those values to avpriv_set_pts_info fps got some extraordinary values too.
[14:04] <someone-noone> Compn, smth similar to mpegts but with some differences.
[14:05] <Compn> michaelni : wow theres a ton of history to look for to find original author copyright in that h264 code :\
[14:05] <Compn> it all gets moved around like crazy
[14:05] <Compn> http://git.videolan.org/?p=ffmpeg.git;a=commit;f=libavcodec/x86/dsputil_mmx.c;h=d0eb5a1174c2626e26bf75801d2b99e1383884ac
[14:13] <someone-noone> I do following: avpriv_set_pts_info(context->video_stream,32,1,24000); 
[14:13] <someone-noone> but ffmpeg -i testfile shows 3.17 fps
[14:16] <michaelni> your timestamps or timebase maybe arent correct, also 24000 is probably not your framerate
[14:17] <someone-noone> michaelni, I got those values(1 and 24000) while muxing. Pseudo code: put_be32(time_base.den); put_be32(time_base.num)
[14:18] <someone-noone> and then passed this values to avpriv_set_pts_info, while demuxing
[14:18] <someone-noone> the original file is in .mp4 format
[14:18] <someone-noone> what am I doing wrong? 
[14:20] <someone-noone> also, original .mp4 file doesn't have r_frame_rate value. So,AFAIK, I should calculate it directly from time_base
[14:20] <someone-noone> r_frame_rate = 1/time_base
[14:24] <someone-noone> as well as: ffmpeg -i test.mp4 shows 23.94 fps
[14:24] <cone-93> ffmpeg.git 03Anton Khirnov 07master:605b047bcc48: rv10: improve buffer size check.
[14:24] <cone-93> ffmpeg.git 03Michael Niedermayer 07master:1c65393906ab: Merge commit '605b047bcc48482dc8a356f56629da259fbddbf1'
[14:24] <someone-noone> sorry, not 23.94, but 23.98
[14:26] <someone-noone> Another question is, what is tbr, tbn and tbc values? If I remember right, those values are stored in codec->flags and codec->flags2 
[14:27] <someone-noone> I thought that providing codec->extradata is enough for correct decoding any codec in ffmpeg
[14:33] <cone-93> ffmpeg.git 03Anton Khirnov 07master:12b54a1f39fe: mpegvideo: remove an unused function parameter
[14:33] <cone-93> ffmpeg.git 03Michael Niedermayer 07master:c7002e3d3dad: Merge commit '12b54a1f39fee22fa0399825ae47a43e60bad4c5'
[14:34] <michaelni> someone-noone, the tbr, tbc, tbn values printed by the command line tool are unrelated to flag fields
[14:36] <someone-noone> michaelni, thanks. Then what are they and should I specify them? 
[14:36] <someone-noone> And any advice about fps? What am I doing wrong?
[14:36] <michaelni> someone-noone, i said it already, your values are wrong
[14:37] <michaelni> either timebase or timestamps
[14:37] <someone-noone> michaelni, timestamps you mean pts?
[14:37] <michaelni> pts and dts
[14:38] <michaelni> it could be other issues too but these are most likely
[14:38] <someone-noone> hm, but I put time_base, pts and dts while muxing directly....
