[01:13:52 CEST] <bofh_> atomnuker: pong
[02:13:58 CEST] <kierank> JEEB: did you fix your h264 bug?
[07:59:00 CEST] <JEEB> kierank: not yet
[11:54:40 CEST] <January> Is there a special way to bisect ffmpeg?
[11:56:08 CEST] <nevcairiel> use the bisect script in the tools folder
[11:56:18 CEST] <thardin> you mean other than git bisect run make fate?
[11:58:52 CEST] <January> thardin: doing that I end up at some nonsensical commits
[11:59:06 CEST] <January> nevcairiel: thanks, will give it a shot
[12:03:55 CEST] <thardin> seems that just does git bisect run but checks that ffmpeg.c etc exists?
[12:06:11 CEST] <funman> yes rather than avconv.c
[12:06:51 CEST] <nevcairiel> yeah it ensures to stay on the right side of the merges
[12:07:34 CEST] <thardin> aha
[12:18:51 CEST] <J_Darnley> Since we are all jumping on to that bug...
[12:18:58 CEST] <J_Darnley> Is there a known good commit?
[12:20:27 CEST] <J_Darnley> kierank, January?
[12:21:01 CEST] <kierank> No
[12:21:14 CEST] <January> I just went back 'far'
[12:21:15 CEST] <kierank> HEAD~1500 or so iirc works
[12:21:22 CEST] <J_Darnley> okay
[12:23:57 CEST] <cone-013> ffmpeg 03Paul B Mahol 07master:3cbf37bf098a: avfilter/af_silenceremove: fix max for duration options
[13:01:24 CEST] <J_Darnley> This bisect tool is a POS!  It looks like it is skipping every commit.
[13:05:05 CEST] <J_Darnley> And now it looks like it deleted the entire tree.
[13:06:56 CEST] <J_Darnley> Is that because some genius decided to move ffmpeg.c to fftools/?
[13:17:36 CEST] <durandal_1707> yes
[13:17:40 CEST] <JEEB> yea, it was moved at one point
[13:22:55 CEST] <akravchenko188> jkqxz: hi, it is reminder.  hwcontext_amf and vf_scale_amf is pending to integrate for a long time. is there any reason? could I fix something or provide some help?
[13:27:16 CEST] <J_Darnley> "cf57cb3ae4364ab8e70af37beea7a45a86de90e9 is the first bad commit"
[13:27:23 CEST] <J_Darnley> "h264: add AVOption to set x264_build default"
[13:27:30 CEST] <J_Darnley> great
[13:38:31 CEST] <cone-013> ffmpeg 03Paul B Mahol 07master:e10fe34e7c60: avfilter/f_reverse: add packed sample format support to areverse
[18:45:34 CEST] <drbuck> I am working on a toy dash live streaming setup.   For debugging, I would like to have pts, dts based on wallclock.  output_ts_offset in mux.c seems like a good fit, but it is not supported in movenc.c.  I'm not an expert on isobmff/cmaf, does output_ts_offset plausibly make sense to support?
[18:48:47 CEST] <JEEB> I think nonzero PTS should work if you just note that it's a thing that starts with a discontinuity
[18:48:50 CEST] <JEEB> IIRC
[18:49:04 CEST] <JEEB> also there's another flag that tells the muxer to not draw your PTS/DTS to zero in the muxer either
[18:50:47 CEST] <JEEB> some value of avoid_negative_ts IIRC
[18:53:55 CEST] <drbuck> @JEEB: looking into it, thx!
[20:34:21 CEST] <llogan> What is the answer to this question? "Is this gcc inlining problem still relevant for FFmpeg"? https://twitter.com/Art1Pirat/status/1049357199343071232
[20:34:47 CEST] <llogan> He then links to https://nadav.amit.zone/blog/linux-inline
[21:58:18 CEST] <tmm1> "Decomposition unimplemented for unit 4 (type 10)" what is this in h264?
[21:59:12 CEST] <tmm1> ah "Coded slice data partition C"
[21:59:25 CEST] <tmm1> err no, that's type 4 not type 10. type 10 is "End of sequence"
[22:43:01 CEST] <BtbN> philipl, so the latest nvidia driver fixes the mapping weirdnes?
[22:50:34 CEST] <philipl> BtbN: an unreleased future driver will.
[22:51:51 CEST] <nevcairiel> probably one that officially claims support for a future nvdec revision that actually has those output formats listed =p
[22:52:09 CEST] <philipl> This is the vulkan interop bug. Different.
[22:52:20 CEST] <philipl> They claim that works in the current driver releases, except it doesn't work for VkImages.
[22:52:33 CEST] <nevcairiel> oh that
[22:54:03 CEST] <BtbN> oh right, Windows has different numbers
[23:02:14 CEST] <durandal_1707> forget about multimedia
[23:03:32 CEST] <durandal_1707> it is full of crap
