[01:26:54 CET] <cone-384> ffmpeg 03Chirag Lathia 07master:d6b1248fc6aa: avcodec/libvpxenc: Add a maximum constraint of 16 encoder threads.
[13:17:37 CET] <cone-187> ffmpeg 03Michael Niedermayer 07master:35040048793b: fftools/ffmpeg: Repair reinit_filter feature
[13:17:37 CET] <cone-187> ffmpeg 03Michael Niedermayer 07master:1f99674ddddc: avcodec/pngdec: Check compression method
[17:39:49 CET] <durandal_1707> anybody against applying av_sscanf() ?
[18:18:23 CET] <philipl> BtbN: that thread on the devtalk forum has generated more traffic. Someone's saying they see an nvenc performance regression in 4.1
[18:18:49 CET] <BtbN> Did they forget hwaccel_output_format?
[18:19:05 CET] <philipl> Was that always necessary or a new requirement in 4.1?
[18:19:22 CET] <philipl> eh. I don't know how he's decoding.
[18:19:24 CET] <BtbN> Well, it is if you want to avoid needles copying around
[18:19:27 CET] <philipl> I'll ask for full comamnd line
[19:41:33 CET] <cone-593> ffmpeg 03Paul B Mahol 07master:4334e9221ee1: doc/filters: improve afftfilt documentation
[19:52:17 CET] <philipl> BtbN: https://devtalk.nvidia.com/default/topic/1042459/video-codec-sdk/nvdec-in-ffmpeg-cuvid-drops-frames-when-using-deinterlacing-deint-2-/post/5297699/#5297699
[19:53:09 CET] <BtbN> Uhm, I don't see how ffmpeg could possibly cause that.
[19:59:29 CET] <philipl> neither do I
[20:08:46 CET] <nevcairiel> i thought t here a re instance limits anyway, even on quadro
[20:12:28 CET] <philipl> Yeah, but he's claiming he's not hitting him as early with 4.0
[20:13:05 CET] <philipl> obviously, I'm not in a position to test without the quadro.
[20:23:33 CET] <cone-593> ffmpeg 03Paul B Mahol 07master:7a73cca2546a: avfilter: add dedot video filter
[20:32:16 CET] <cone-593> ffmpeg 03Paul B Mahol 07master:4b30726dd39f: lavu: add locale-independent sscanf implementation
[20:32:17 CET] <cone-593> ffmpeg 03Paul B Mahol 07master:4902780d2b53: avfilter/vf_lut3d: use av_sscanf
[20:36:35 CET] <JEEB> huh, I remember just some time ago both of the closed caption specs were nonfree
[20:36:47 CET] <JEEB> now you can at least get the CTA versions for free?
[20:36:53 CET] <JEEB> https://members.cta.tech/ctaPublicationDetails/?id=a10017f5-a01c-e811-90ce-000d3a0072d6
[20:39:48 CET] <durandal_1707> just use ccextractor?
[20:43:45 CET] <JEEB> durandal_1707: for decoding we already have crap anyways
[20:44:20 CET] <durandal_1707> incomplete
[20:45:32 CET] <durandal_1707> anybody have pristine video samples with rainbows artifacts?
[21:41:40 CET] <cone-593> ffmpeg 03Paul B Mahol 07master:395508d9b6c7: avfilter/vf_dedot: initizalize ret variable
[21:46:30 CET] <cone-593> ffmpeg 03Carl Eugen Hoyos 07master:21dd05ee6ad3: lavfi/minterpolate: Remove declaration of two unused variables.
[22:04:46 CET] <cone-593> ffmpeg 03Carl Eugen Hoyos 07master:fc94e9704e05: lavf/hlsenc: Do not mix declarations and code.
[22:16:26 CET] <durandal_1707> the cnr(2) plugin produce ghost artifacts in chroma and does not get rid of rainbows under default settings
