[08:09:12 CEST] <cone-788> ffmpeg 03Lauri Kasanen 07master:ce92ee4b4f3e: swscale/ppc: VSX-optimize non-full-chroma yuv2rgb_2
[11:59:50 CEST] <cone-788> ffmpeg 03Paul B Mahol 07master:0f2835597484: avcodec/agm: add support for higher compression
[11:59:51 CEST] <cone-788> ffmpeg 03Paul B Mahol 07master:7be8f7ac8143: avcodec/agm: add support for non-dct coding
[11:59:52 CEST] <cone-788> ffmpeg 03Paul B Mahol 07master:d0f24df648f4: avcodec: add ADPCM AGM decoder
[13:44:05 CEST] <durandal_1707> michaelni: what type of NALs are those? : https://github.com/richardpl/FFmpeg/blob/imm5/libavcodec/h264dec.c#L956 
[13:45:19 CEST] <nevcairiel> 0x67 in the 5th spot is SPS, 0x68 is PPS
[13:45:32 CEST] <JEEB> if it's H.264 the spec should have a nice list
[13:45:35 CEST] <JEEB> for NAL unit types
[13:47:54 CEST] <nevcairiel> note that the type is only  0x1f of that byte, so its 7 and 8, ie. sps and pps
[14:02:46 CEST] <durandal_1707> and what they contain?
[14:03:18 CEST] <nevcairiel> information to decode the video!
[14:03:18 CEST] <nevcairiel> :)
[14:03:30 CEST] <durandal_1707> like?
[14:04:05 CEST] <nevcairiel> read the syntax spec yourself =p
[14:04:50 CEST] <nevcairiel> profile, width/height/bitdepth, all that stuff, various flags
[14:26:00 CEST] <pranayvshah> Is this the right place to hire an ffmpeg dev from?
[14:26:17 CEST] <JEEB> this has developers at least :P
[14:26:39 CEST] <JEEB> the ffmpeg-devel mailing list is another venue since I don't think we have a specific list for offers
[14:28:17 CEST] <pranayvshah> Alright, will post there too. I went through drawtext filter's .c code and libfribidi seems to be the only shaper supported. Who would be the right dev to add support for harfbuzz and are they available for contracting work?
[14:31:33 CEST] <BradleyS> i believe libass uses harfbuzz if enabled, and ffmpeg can use libass if enabled
[14:31:50 CEST] <BradleyS> this is how we use harfbuzz in handbrake, for example
[14:32:34 CEST] <pranayvshah> But that's just the ass/subtitles filter, drawtext wouldn't use libass right?
[14:33:11 CEST] <BradleyS> indeed, subtitles only but might be helpful reference
[14:34:24 CEST] <BradleyS> see also http://ffmpeg.org/consulting.html
[14:34:48 CEST] <BradleyS> and do email the ffmpeg-devel mailing list
[14:35:11 CEST] <pranayvshah> Agreed, and will email to the dev list. Thank you :)
[14:44:15 CEST] <durandal_1707> aren't there ass filter?
[14:45:19 CEST] <JEEB> yup, for cases where a static ASS file can be generated it should be good enough
[14:45:43 CEST] <JEEB> since it effectively just tells libass to parse an ASS file
[19:47:54 CEST] <cone-562> ffmpeg 03Michael Niedermayer 07master:3308e3da045e: avcodec/agm: Check frame dimensions
[20:47:47 CEST] <cone-562> ffmpeg 03James Almer 07master:80e9f50f82a7: avcodec: add an AV1 frame split bitstream filter
[21:05:12 CEST] <cone-562> ffmpeg 03James Almer 07master:c5a825dc7536: configure: fix av1_frame_split bsf dependencies
[21:47:41 CEST] <cone-562> ffmpeg 03Marton Balint 07master:6ed7df5b20e4: avformat/mxfdec: export operational pattern UL as file metadata
[21:47:42 CEST] <cone-562> ffmpeg 03Marton Balint 07master:3e10223385b8: avformat/file: add seekable option to disallow seeking
