[12:42] <random3234> hi guys im not sure im am in the correct forum/room here but I have been downloading ffmpeg git static builds for the last few days and benchmarking and todays build (ffmpeg-git-20141008-64bit-static) has had a performance drop of 50%
[12:42] <random3234> here is the command line
[12:42] <random3234> ./ffmpeg -benchmark -i /spare/x265-daily-tests/blue_sky_1080p25_cfr28.x265 -s 1280x720 -vcodec libx265 -preset superfast -x265-params bframes=0:threads=1:crf=30 -f rawvideo /tmp/blue_sky_1080p25.x265
[12:42] <random3234> i understand this could simply be x265 related but  i wanted to raise it 1st
[12:42] <random3234> in herre
[12:44] <random3234> i have seen the fps drop from 31fps down to 13/14 on a fixed test
[12:54] <wm4> did you test with the same x265 lib?
[13:00] <random3234> my understanding is that the ffmpeg static build lifts the daily x265 build
[13:00] <random3234> so to answer then i presume it wud be a different x265
[13:20] <JoshX> hello.. just asked the following in the main #ffmpeg channel too.. not sure where to ask it :)
[13:20] <JoshX> Hello, Small question.. so far i've only found a patch which would mean i would need to recompile ffmpeg myself and i don't really want a custom version, but does ffmpeg support a filename pattern which would include date/time in the format 20141008_131714004 (yyyymmd_ hhmmssfff) while using the segmentation options where the filename would include the start time of the segment?
[13:40] <pa> ubitux, so i finally explained my problem in a ML post :) let's see if this will work out
[13:41] <pa> ffmpeg-user though, even if the topic is a little in between ffmpeg-user and ffmpeg-devel
[13:58] <wm4> link?
[14:10] Action: Compn reviews moderation queue
[14:13] <Compn> there, i think i approved pa's mail
[14:13] <spaam> moderator Compn 
[14:13] <Compn> wm4 : http://lists.ffmpeg.org/pipermail/ffmpeg-user/2014-October/023818.html
[14:14] <Compn> pa : btw did you look at mplayer/TOOLS/netstream.c ? :P
[14:14] <wm4> netstream is a joke
[14:21] <wm4> pa: funky stuff
[14:26] <wm4> pa: I'm not subscribed to that list
[14:27] <wm4> pa: I think the strange seek behavior you see is due to http://git.videolan.org/?p=ffmpeg.git;a=blob;f=libavformat/aviobuf.c;h=f01ed8843bdc33f5f63040d0b7a9522687fdd80f;hb=HEAD#l241
[14:27] <wm4> probably
[14:27] <wm4> which was added in 9600486d10a9728f1503363334268ecfafa9b0e5 (2014!)
[14:28] <wm4> apparently it was done for mp3 backwards seeking? (lolwut)
[14:28] <wm4> (a wtf to be found here)
[14:28] <wm4> pa: anyway, the point is: the demuxer is free to do that
[14:29] <wm4> pa: run mpv with --demuxer-mkv-subtitle-preroll to see even stranger behavior
[15:10] <pa> thanks Compn !
[15:13] <pa> wm4, let me try
[15:18] <pa> wm4, actually it behaves the same with that switch (on a regular file)
[15:18] <pa> meaning, well. requesting cluster boundary offsets and all

[16:25] <arwa> Hey when I am compiling the xbr.c , I am getting this error ---> " no previous prototype for ‘xbr2x_a’ ".
[16:32] <cone-470> ffmpeg.git 03Carl Eugen Hoyos 07master:1d4480d376b0: tests/Makefile: Fix fate-ffprobe with --target-path
[17:05] <saste> arwa: do you have a link to the xbr repo?
[17:23] <ubitux> arwa: make that function static
[17:38] <reynaldo> people, can we try sticking dates for the qualification tasks at https://trac.ffmpeg.org/wiki/SponsoringPrograms/OPW/2014-12-Qualis
[17:39] <cone-470> ffmpeg.git 03Tobias Rapp 07master:33db99548b99: Changelog: add "ffprobe -show_pixel_formats option"
[17:58] <arwa> okay thanks :D
[18:01] <ubitux> arwa: if you don't the function is exported, and so is exposed; and in your case the prototype was missing so it couldn't be exported properly
[18:01] <ubitux> (to make things simple)
[18:02] <arwa> ohh!! 
[18:17] <arwa> I am getting a scaled checkered image as output for a totally different input image. :/
[18:19] <reynaldo> ubitux: just CCed you on a vp9 patch on -devel, not sure you took a look at it already
[19:04] <chetna> Hi Michaelni & Daemon404. I was wondering if you could give me some introductory links/docs to look through "FFv1 P Support" idea. Please let me know if any of you  are around ?
[19:36] <michaelni> 19:04 <chetna> Hi Michaelni & Daemon404. I was wondering if you could give me some ... 19:17 chetna has quit <-- too quick
[19:44] <hima> ubitux: how can i compile and run a file here . Like just srtdec.c if i want to print certain statements so as to understand how the code works? or i just have to use ffmpeg -i in.srt out.srt
[20:38] <Mavrik> uh
[20:38] <Mavrik> so what's the proper way to make a copy of an AVPacket?!
[20:40] <cone-470> ffmpeg.git 03Michael Niedermayer 07master:be695ee38972: avformat/matroskadec: do not trust the default duration to be the real 1/timebase if its less than 5fps
[20:40] <Mavrik> I keep getting  av_freep crashes when using av_packet_unref and I have no idea what I'm doing wrong
[20:46] <michaelni> Mavrik, dunno what exactly you want to do but av_copy_packet() might do what you want
[20:47] <Mavrik> and now I look like a moron for not seeing that method. Thanks.

[23:28] <J_Darnley> Where is the code the governs input streams going into the filter chain in ffmpeg (the tool)?
