[15:17:23 CET] <taliho> anyone able to reproduce https://trac.ffmpeg.org/ticket/8285 ?
[15:19:00 CET] <taliho> tried to set v4l2_m2m on encoding/decoding on raspi 4, but don't have any memleaks when testing on the sample 
[15:40:52 CET] <mkver> All I know about said ticket is that there is already an attempted fix on the ML: https://ffmpeg.org/pipermail/ffmpeg-devel/2019-October/251940.html
[15:43:05 CET] <taliho> :mkver I was trying to test the fix
[17:28:52 CET] <taliho> ok, I couldn't reproduce because I had a valid v4l2_m2m device on the raspi. Can reproduce on a different machine
[21:36:47 CET] <tmm1> anyone working on AC4 decoder?
[21:37:15 CET] <JEEB> i think durandal_1707 was but he got fed up doing it for free
[21:37:23 CET] <JEEB> or something
[21:37:30 CET] <JEEB> also apparently it wasslow
[21:38:05 CET] <JEEB> he might have something wip in vis girhub
[21:38:18 CET] <Lynne> durandal_1707 but couldn't continue without samples which used more features
[21:38:33 CET] <JEEB> right
[21:39:02 CET] <JEEB> i only knew the ones on dash if sample repo
[22:02:35 CET] <jamrial> someone on #videolan posted a few dash broadcast samples (ac4 in isobmff) the other day
[22:15:25 CET] <durandal_1707> few?
[22:18:33 CET] <tmm1> i have some samples from astc3 ota and also someone interested in sponsoring dev
[22:20:45 CET] <durandal_1707> i need full ac4 coverage, not some sloppy samples
[22:21:05 CET] <durandal_1707> ac4 is more complex than ac3
[22:21:43 CET] <durandal_1707> with different versions and channel layouts
[22:29:59 CET] <jamrial> durandal_1707: short of a test suite, you're unlikely to get full coverage for such a format. even if every broadcaster switches to it
[22:34:03 CET] <durandal_1707> tmm1: i already wrote functional decoder, so i dunno what you want
[22:35:11 CET] <Lynne> just call avpriv_report_missing_feature() to nag users for samples
[22:41:34 CET] <tmm1> durandal_1707: have a link?
[22:44:58 CET] <durandal_1707> tmm1: why you need a link? its public
[23:07:41 CET] <tmm1> ok i will search
[23:10:15 CET] <tmm1> https://github.com/FFmpeg/FFmpeg/compare/master...richardpl:ac4
[23:35:01 CET] <JEEB> meanwhile Japan seems to have picked MPEG-H 3-D audio
[23:35:47 CET] <JEEB> which is probably why sony posted a demux patch  for it
