[15:15:58 CET] <ubitux> why is ffmpeg.c mux_timebase set to the encoder timebase instead of the output AVStream timebase set by the muxer itself?
[15:16:07 CET] <ubitux> i'm confused.
[15:17:49 CET] <Compn> in case codec and container timebase differ ?
[15:18:18 CET] <Compn> maybe hardware encoders ?
[15:32:16 CET] <ubitux> the pkt timestamps are rebased from the encoder timebase to the muxer timebase before being sent to the muxer
[15:32:24 CET] <ubitux> but in ffmpeg it seems kind of different
[15:32:40 CET] <ubitux> it's like, it's converted from encoder time base, to a muxer timebase and then to the ost tb
[15:32:59 CET] <ubitux> there is this intermediate mux timebase which isn't actually about the muxer
[15:33:16 CET] <ubitux> since the muxer expect it in ost timebase
[15:33:25 CET] <ubitux> (defined by itself)

[16:51:48 CET] <cone-314> ffmpeg 03Derek Buitenhuis 07master:8f585c3c550c: mov: Remove duration-of-last-frame heuristic hack
[17:05:20 CET] <atomnuker> kierank: https://www.scotsman.com/news/uk-government-fighting-eu-plans-to-end-daylight-saving-time-1-4849258
[17:05:50 CET] <thardin> haha what
[17:05:58 CET] <nevcairiel> what does the UK care, dont you want to be gone by then
[17:05:59 CET] <atomnuker> are they just doing it because they can and it won't matter soon?
[17:06:26 CET] <thardin> they're out by what, march this year?
[17:06:32 CET] <thardin> april maybe
[17:08:48 CET] <atomnuker> nevcairiel: wish I knew where to go, it seems to me its all bad everywhere
[20:08:21 CET] <atomnuker> it'd be nice if taxes weren't inversely proportional to internet speeds, >= 40% is insane
[20:28:33 CET] <durandal_1707> using avx should be faster that pure sse3 by what amount?
[20:28:47 CET] <nevcairiel> anything from 0 to 100%
[20:29:08 CET] <durandal_1707> why?
[20:29:41 CET] <nevcairiel> if its entirely compute bound and stuff scales perfectly with bigger registers, you can get 100% increase (well, almost, anyway)
[20:29:54 CET] <nevcairiel> if  other factors are limiting it, then it'll be lower then that
[20:29:57 CET] <nevcairiel> there is no one answer
[20:33:56 CET] <durandal_1707> what other factors?
[20:37:44 CET] <kurosu> amd
[20:38:50 CET] <nevcairiel> memory access may be a concern, and there is always the lane business to consider depending on  how the data is structured and has to be moved
[20:40:25 CET] <nevcairiel> pretty short algorithms may also cost a bit more due to avx clock changes, although that factor is disappearing more and more with newer gen cpus
[20:40:58 CET] <nevcairiel> and of course AMD only has  128-bit ALUs, so they dont benefit from avx much, if at all. presumably thats changing with zen2 though, so yay for that, i guess
