[00:17:07 CEST] <cone-547> ffmpeg 03Mark Thompson 07master:581b4125aa18: lavc/h264_levels: Avoid integer overflow in bitrate
[00:17:08 CEST] <cone-547> ffmpeg 03Mark Thompson 07master:321294adb788: h264_metadata: Avoid integer overflow in bitrate
[00:17:09 CEST] <cone-547> ffmpeg 03Mark Thompson 07master:feb1cf08ab39: lavc/h265_profile_level: Avoid integer overflow in bitrate
[00:17:10 CEST] <cone-547> ffmpeg 03Mark Thompson 07master:1215fbad96da: lavc/h265_profile_level: Fix level guessing with no PTL structure
[00:17:11 CEST] <cone-547> ffmpeg 03Mark Thompson 07master:74b4134d2f57: vaapi_encode_h265: Add missing error return
[00:20:02 CEST] <jamrial> jkqxz: got a "trailing_one_bit out of range: 0, but must be in [1,1]." error on a freshly made monochrome av1 sample
[00:20:27 CEST] <jamrial> apparently on the sequence header
[00:23:15 CEST] <jkqxz> Hmm.  Link?
[00:23:26 CEST] <jkqxz> Probably a desync somewhere which it only finds at the end.
[00:24:01 CEST] <jamrial> jkqxz: https://code.videolan.org/videolan/dav1d/uploads/39460802304c1b4f16e8ec035dfa47e3/mono.ivf
[00:26:20 CEST] <jamrial> jkqxz: ah, color_range
[00:26:58 CEST] <jamrial> you're using infer for the value when you should read a bit when monochrome is 1
[00:27:51 CEST] <jamrial> did you see the cbs based parser i submitted to the ml, for that matter?
[00:28:34 CEST] <jkqxz> Yes, I'm just looking at that.
[00:28:56 CEST] <jamrial> it will give cbs_av1 some good testing once committed :p
[00:31:03 CEST] <jkqxz> Right, color_range for mono_chrome.  Fixed.
[00:32:30 CEST] <jkqxz> (Wtf is with that crazy BT.709/sRGB/RGB special case?  It saves like 1 bit in the sequence header and makes you have stupid extra code to handle it.)
[00:33:51 CEST] <jamrial> that'd be gbrp pix_fmt if we were to implement it in the libaomdec wrapper
[00:36:18 CEST] <jkqxz> I guess raw HDMI streams aren't really an intended use-case, but they often fall exactly into the disallowed case (BT.709, sRGB, limited range).
[00:36:55 CEST] <jamrial> the reduced sitll picture header stuff is more annoying imo. it saves a few bytes in the sequence header for still images but makes parsing a mess
[00:39:48 CEST] <atomnuker> jkqxz: yeah, you can blame me for that :p
[00:40:09 CEST] <jkqxz> To stop people using AV1 for HDMI?
[00:43:47 CEST] <atomnuker> no, not directly, the reasons I remember giving were that it was a modern codec for the internet, and not a dumping ground for outdated broadcast hacks, and also because we'd have to define what limited range rgb is, and we were writing a codec
[00:45:09 CEST] <jkqxz> But why that specific combination?  It lets you have limited range RGB, just not in sRGB with BT.709 transfer.
[00:46:16 CEST] Action: atomnuker checks specs
[00:50:05 CEST] <atomnuker> hm, maybe it should have been allowed for BT601 as well, but IIRC 2020 didn't allow limited range rgb, and I'm not sure about the rest with TC_SRGB (CP_XYZ + TC_SRGB == ?)
[00:56:38 CEST] <jkqxz> atomnuker:  Btw, what was the error you mentioned last night?
[01:04:32 CEST] <atomnuker> it gets printed when mpv inits a hardware decoder
[01:05:11 CEST] <atomnuker> checked, it didn't happen before the patchset, and there's only 1 patch which touched a seemingly unrelated part in hwcontext_vaapi
[01:06:11 CEST] <jkqxz> Yeah, I was going to say that it didn't touch anything decode...
[01:06:17 CEST] <jkqxz> Intel or AMD?
[01:11:38 CEST] <jkqxz> Oh, it's in the testing step when it tries to work out what formats are mappable.
[01:16:51 CEST] <jkqxz> The test is mapping YUYV as separate planes and failing with that error.
[01:17:00 CEST] <jkqxz> I don't see why it would have been changes by that commit, though.
[05:17:30 CEST] <cone-157> ffmpeg 03Steven Liu 07master:a7429d853de0: avfilter/buffersink.h: fix comment typo of av_buffersink_get_samples
[15:10:41 CEST] <durandal_1707> http://sound-of-pixels.csail.mit.edu/ -----> this my next project
[15:12:26 CEST] <thardin> now generate mpeg-7 metadata for each instrument
[15:58:26 CEST] <cone-383> ffmpeg 03Steven Liu 07master:bb660800a55f: avformat/utils: move mkdir_p to utils
[16:38:05 CEST] <BBB> atomnuker: ty for msac patch, so are you interested in the idea of rewriting it, or not really?
[16:38:44 CEST] <cone-383> ffmpeg 03Paul B Mahol 07master:d6e50e0716d5: avfilter/vf_curves: add planar rgb support
[17:31:14 CEST] <cone-383> ffmpeg 03Matthieu Bouron 07master:e294b5cf6464: RELEASE: update for git after 4.0 branchpoint
[18:16:42 CEST] <kierank> anyone actually in paris?
[18:18:31 CEST] <BBB> me
[18:18:41 CEST] <BBB> henrik and luc also
[18:18:44 CEST] <BBB> and some videolan people
[18:19:09 CEST] <kierank> I have a ticket for biffy clyro tonight at the bataclan
[18:26:34 CEST] <BBB> isnt bataclan that place?
[18:27:43 CEST] <kierank> yes
[18:30:50 CEST] <durandal_1707> this is ffmpeg development channel, for finding people who will take free ticket(s) search elsewhere
[18:35:08 CEST] <BBB> Im trying to imagine my wifes reaction if I tell her I went to a concertn in that place :-p
[18:36:22 CEST] <BBB> also, listening to that band, I think its for dates, not nerds?
[18:36:27 CEST] <BBB> I dont know
[18:40:37 CEST] <kierank> BBB: probably true but I have been given 2 free ticket
[18:41:29 CEST] <BBB> probably not quite my thing, sorry& but thanks for asking
[18:43:41 CEST] <durandal_1707> kierank: find (x/y/xy/yx)friend in that fancy hotel?
[18:43:56 CEST] <kierank> not doable in 15 minutes
[18:47:30 CEST] <BBB> ignore concert and go have a nice dinner with us
[18:48:38 CEST] <kierank> I need to find some time away from tech for a while
[18:48:48 CEST] <kierank> but maybe a pint after your dinner if you are still free
[18:54:07 CEST] <BBB> ok, happy to
[19:32:50 CEST] <durandal_1707> huh, KGB? some ffv1 commit did not get through?
[19:54:31 CEST] <cone-383> ffmpeg 03Paul B Mahol 07master:efb65abedf40: avfilter: add audio denoising (afftdn) filter
[21:01:00 CEST] <llogan> durandal_1707: forgot about that one
[21:01:23 CEST] <durandal_1707> llogan: Carl?
[21:01:37 CEST] <llogan> yeah. look at what you started.
[21:01:53 CEST] <llogan> that one is already in the heap, so perhaps it will go up the queue
[21:02:12 CEST] <durandal_1707> we should finally start using our names: Carl, Michael, James, Lou
[21:06:57 CEST] <BradleyS> durandal_1707: see, i knew you were four people
[21:31:45 CEST] <kierank> Gramner: are you guys around in 30-40 minutes?
[21:38:03 CEST] <durandal_1707> i'm coming pronto: https://www.youtube.com/watch?v=VSrEIdhrXB4
[21:52:00 CEST] <durandal_1707> github down!
[22:16:07 CEST] <kierank> SAD!
[22:16:53 CEST] <durandal_1707> kierank: it is no more down
[22:18:26 CEST] <gnafu> Thanks, Microsoft!
[22:24:14 CEST] <durandal_1707> michaelni: please fix KGB
