[13:44:38 CET] <poste9> guys whats the container do I have to use for hevc ?
[13:44:46 CET] <poste9> no success with mp4
[13:44:58 CET] <wm4> mp4 should work
[13:45:09 CET] <wm4> it has official hevc support
[13:47:49 CET] <nevcairiel> does avformat support proper muxing yet?
[13:48:07 CET] <nevcairiel> mp4, mkv and TS at least have official format hookups
[13:49:12 CET] <wm4> seems movenc has some special-cases for hevc
[13:49:17 CET] <wm4> but who knows if it's correct
[14:22:30 CET] <poste9> are there any known issues regarding the fact the container mp4 handles pts and dts different than mp4 ?
[14:22:46 CET] <nevcairiel> wat
[14:22:52 CET] <poste9> using the same algorithm the file in mp4 has 5 seconnds and the mkv has like 30 minutees
[14:27:38 CET] <Daemon404> re-read what you wrote
[14:32:13 CET] <Compn> you wrote mp4 twice poste9
[14:32:32 CET] <poste9> oh my bad
[14:32:33 CET] <Compn> poste9 : is there a bug in mp4 or mkv with duration ?
[14:32:35 CET] <poste9> its mp4 and mkv
[14:32:52 CET] <poste9> just changing the output format
[14:32:56 CET] <Daemon404> well for one mkv doesnt have dts.
[14:32:58 CET] <poste9> the result in duration is huge
[14:33:05 CET] <Compn> what command line ?
[14:33:17 CET] <Compn> and what ver ffmpeg ?
[14:33:19 CET] <poste9> its my own code
[14:33:30 CET] <poste9> maybe Im just doing something stupid
[14:33:39 CET] <Compn> ah
[14:33:42 CET] <poste9> thats why I wanted to know if there are any known issues
[14:34:05 CET] <Compn> well thats why i suggest testing it with ffmpeg, if it works, then its bug in your code, if it shows duration problem, then its our bug
[14:34:06 CET] <Compn> ;)
[14:34:41 CET] <Compn> hard for us to remember thousands of bugs on the fly, especially this early in the morning 
[14:34:42 CET] <ubitux> i think we forgot to announce 2.6 on the website
[14:35:34 CET] <poste9> yea my bad... command line working ok
[14:35:47 CET] <poste9> ffmpeg -y -loglevel debug -debug_ts -f v4l2 -i /dev/video0 -f mp4 -qmin 30 -qmax 51 -crf 23 -t 5 -r 10  test.mp4 
[14:35:56 CET] <poste9> ffmpeg -y -loglevel debug -debug_ts -f v4l2 -i /dev/video0 -f matroska -qmin 30 -qmax 51 -crf 23 -t 5 -r 10  test.mkv
[15:47:24 CET] <saste> michaelni, ubitux, about eq, do you thing it makes sense to let it accept an expression?
[15:47:48 CET] <saste> also, in case of a T/N expression, should I check in case the value changes and recompute the lut?
[15:47:56 CET] <saste> I think so, but that's potentially slow
[15:48:09 CET] <michaelni> i think it makes sense to allow expressions
[15:48:38 CET] <saste> so I was thinking about a mixed approach, like to implement several evaluation policy (like in overlay IIRC)
[15:48:52 CET] <saste> "once" or "per-frame" (but it's better if I benchmark first)
[15:49:35 CET] <ubitux> no opinion, but i think timeline support would be welcome
[16:03:07 CET] <michaelni> saste, a option to swicth to per frame eval is fine 
[16:05:25 CET] <iive> can't it be automatic?
[16:05:49 CET] <iive> e.g. if some parameter is changed, check if the formula is using it?
[16:33:32 CET] <michaelni> iive, yes, it can, do you want to implement it? (its probably not hard could even be done by dumb string search)

[17:43:02 CET] <battleboi> Hey .. which file is responsible for parsing the ffserver's stream file?
[17:43:42 CET] <ubitux> my guess is ffserver_config.c
[17:44:00 CET] <ubitux> ah, stream file, i guess i'm wrong then
[17:44:10 CET] <ubitux> libavformat/ffm*.c
[17:45:29 CET] <battleboi> There are so many files with the name ffm!
[17:45:51 CET] <battleboi> ffmdec, ffmmen, ffmmeta!
[17:46:11 CET] <battleboi> They all handle the stream.html file?
[17:47:11 CET] <battleboi> umm .. what does ffm stand for @ubitux?
[17:48:06 CET] <battleboi> nevermind got it.. thanks @ubitux.

[17:52:58 CET] <wm4> what always triggers this?
[17:53:11 CET] <wm4> it happens suspiciously often when mixing up something
[18:01:06 CET] <durandal_1707> wm4: it is used by vf_pp
[18:01:12 CET] <wm4> I know
[18:19:28 CET] <ninten> durandal_1707, ping !!
[18:19:38 CET] <durandal_1707> ninten: pong
[18:21:04 CET] <ninten> during the decoding of floating seq somtime they may be compressed, so for that we have to use some decompression algo for that
[18:21:54 CET] <ninten> so can i use masek lz decom given in ref pdf 
[18:22:43 CET] <cone-319> ffmpeg 03Michael Niedermayer 07release/1.1:73bfb2167201: Update for 1.1.16

[18:27:35 CET] <ninten> durandal_1707,  do you have that ref pdf right now with you , i have one doubt to ask !!
[18:30:32 CET] <ninten> thr is this function decodeString() it takes a string_code as an input value and returns the decoded character string related to the string_code by searching the dictionary, so this dictionary must be accessible from somewhere i cant find that function !!!
[18:50:54 CET] <speed_> Hey .. I have decent C programming skills, I have fair enough awareness of how AV is handled.. I wish to become a long term contributor of FFMPEG and VLC player.. What's the best way for me to get familiar with your code base?

[19:20:49 CET] <jamrial> i think some mentioned that no more than 5 or 6
[19:21:53 CET] <andrei_il> jamrial: thanks a lot !
[19:31:41 CET] <Guest81177> Hey I have been going through this file ffm. There are functions in it that nothing calls! like ffm_read_packet

[20:31:07 CET] <ubitux> ok so it seems libav is adding the udp options, but with different names

[20:31:47 CET] Action: ubitux would guess they actually look at ffmpeg for the forgotten options
[20:32:49 CET] <Daemon404> thats not even consistent with itself
[21:10:58 CET] <joey_> Hey is Mr. Nicolas George online?
[21:19:55 CET] <jamrial> joey_: not at the moment. try emailing him
[21:20:23 CET] <joey_> @jamrial when is he usually online in IRC? any idea?
[21:27:22 CET] <jamrial> not really
