[01:32:24 CEST] <cone-822> ffmpeg 03Zhong Li 07master:550372d0c436: MAINTAINERS: add myself to qsv section
[02:28:14 CEST] <jamrial> jkqxz: nice
[02:28:51 CEST] <jamrial> i guess there's nothing useful that could be done for a jpeg metadata bsf?
[02:29:22 CEST] <jkqxz> You could do some exif stuff if you wanted.
[02:32:16 CEST] <jkqxz> But that's pretty complex and better delegated to other libraries.
[03:32:39 CEST] <atomnuker> I wish there was a jpeg rotate bsf, but that would require almost fully decoding the image
[03:46:35 CEST] <nevcairiel> didnt jpeg have this lossless easy rotation thing
[03:50:23 CEST] <atomnuker> yeah, to do that you need to decode all coefficients, transpose them, rearrange the blocks, redo dc-prediction and reencode the image
[08:48:41 CEST] <atomnuker> jkqxz: you should probably know kmsgrab works on a raspberry pi 3 (aarch64), with no screen attached
[14:08:33 CEST] <durandal_1707> atomnuker: why are you so slow developer?
[14:12:10 CEST] <atomnuker> hey, I've just got my motivation back to work on ffv2 again, so that's what I've been doing for the last few days
[14:13:49 CEST] <durandal_1707> atomnuker: i see you have really serious problems - not completing anything, starting everything
[14:14:58 CEST] <atomnuker> its a ton of work to complete something that will work as expected and not have any bugs at all, you know?
[14:17:23 CEST] <durandal_1707> atomnuker: you will never finish atrac9 that way
[14:18:46 CEST] <atomnuker> I'll finish it, just need a bit more time
[14:29:30 CEST] <kierank> atomnuker: is this the same ffv2 as pengvado's?
[14:36:47 CEST] <atomnuker> no, its different, its subtitle might as well be "I can't believe its not Daala!"
[14:37:55 CEST] <atomnuker> it uses the untrimmed daala ec system, the daala transforms, the overlap filter as well
[14:38:53 CEST] <atomnuker> but I've extended the lap filter to work with 64-point segments, the block splitting code to allow for arbitary rectangular splitting
[14:40:21 CEST] <atomnuker> its still pretty much all rewritten, no code directly used from daala
[14:41:21 CEST] <atomnuker> it does beat jpeg currently without any prediction at all, just using the lap filter and the same quantization as vc2
[14:43:19 CEST] <atomnuker> btw has anyone heard from pengvado in the last 3 years?
[14:44:41 CEST] <JEEB> he has popped up every now and then
[14:45:22 CEST] <atomnuker> my logs only go back 2 years, but I'm pretty sure I've never seen him since I've been around here
[14:46:11 CEST] <January> I've only ever seen them in old x264 logs
[14:48:01 CEST] <atomnuker> I've heard he's a millionare, you know, and he lives off of baked beans and doesn't have an aquapark
[15:18:35 CEST] <atomnuker> kierank: btw iter has a livestream you can watch construction with - https://www.iter.org/news
[15:18:47 CEST] <kierank> what happened to gagandeep
[15:19:19 CEST] <kierank> atomnuker: being in france i assume they are striking
[15:21:32 CEST] <atomnuker> no, they're working day and often at night
[15:22:46 CEST] <atomnuker> (probably the japanese, they have a deal where they gave up their bid for location in return for more people involved in construction)
[15:23:21 CEST] <atomnuker> kierank: was that ganesh?
[15:23:27 CEST] <kierank> no
[15:23:30 CEST] <kierank> gagandeep is my gsoc student
[15:27:49 CEST] <cone-598> ffmpeg 03Sergey Lavrushkin 07master:d29c35b4d8f1: libavfilter/vf_srcnn.c: adds DNN module backend AVOption, changes AV_LOG_INFO message to AV_LOG_VERBOSE.
[15:27:49 CEST] <cone-598> ffmpeg 03Sergey Lavrushkin 07master:648361c2faf3: libavfilter/dnn_interface.c: fix av_freep dnn_module.
[21:14:41 CEST] <cone-598> ffmpeg 03Gyan Doshi 07master:9c12938ec504: ffmpeg: mark sseof as an input-only option
[23:45:50 CEST] <cone-598> ffmpeg 03Marton Balint 07master:183db8a80bba: avformat/mxfdec: use MXFCodecUL struct to store essence description for data_essence_container_uls
[23:45:51 CEST] <cone-598> ffmpeg 03Marton Balint 07master:f9e77586cb75: avformat/mxfdec: recognize SMPTE 436 VBI data
[23:45:51 CEST] <cone-598> ffmpeg 03Marton Balint 07master:5d3f78383e0e: avformat/mxfdec: only disallow seek on metadata streams
[23:45:53 CEST] <cone-598> ffmpeg 03Marton Balint 07master:d48fb904fa81: avformat/mxfdec: remove check for NULL MXFTrack in mxf_set_pts
[23:45:53 CEST] <cone-598> ffmpeg 03Marton Balint 07master:d070d6f69df7: avcodec/avcodec.h: add AV_CODEC_ID_TTML
[23:45:54 CEST] <cone-598> ffmpeg 03Marton Balint 07master:2bd26dea6636: avformat/mxfdec: add support for recognizing timed text streams
[23:53:26 CEST] <JEEB> woah, I almost had a heart attack when I saw AV_CODEC_ID_TTML
[23:57:22 CEST] <atomnuker> why?
[23:57:55 CEST] <JEEB> I've got bad memories with it
[23:58:26 CEST] <JEEB> (also the pants-on-head level TTML in MP4 spec)
