 > Sorry guys but the discussion is really long and for the largest part
 very old. I just wanted to know if there's a summary of the current status
 of HDR10, HDR10+, DV, etc. in ffmpeg, both for decoding and encoding.
 Thank you.

 Nothing really changed so far, but we are much closer, HDR10+ patches from
 Google are much more ready; DV IPTPQc2 colorspace is also soon to be
 added, just need some polish on the reshaper and we have an app for PC
 from Dolby; BT.2390 color DTM for static metadata is implemented in mpv
 (but not black point correction in it, alas), it also implemented change
 from 100 nits to 203 nits for SDR in HDR reference white per BT.2408. Also
 we have all patches to support HDR meta throughput
 but as there are changes in meta inside container, and more (you can read
 about it here https://www.mail-archive.com/ffmpeg-
 devel at ffmpeg.org/msg108319.html).
