Comment (by Balling):

 Yeah, looks nice. The only moment I dunno is MFVideoPrimaries_DCI_P3. Is
 it DCI-P3 or actually Display P3 (DCI-D65 uses D65)? Sigh. Not documented
 by Micro.

 Also, fallback to primaries/trc and stuff already happens here:
 https://github.com/FFmpeg/FFmpeg/blob/bc70684e74a185d7b80c8b80bdedda659cb581b8/libavfilter/vf_colorspace.c#L74

 Also, is P010BE signalisation is actually big endian or is that (as Carl
 noted) actually little endian and dshow is just swapped??

 Also see my patch for P010LE and P010BE support in nut.c and raw.c!

 I need somebody to create FATE hashes for me though, as it is very hard to
 do so, there is insane amount of hashes to update see
 https://patchwork.ffmpeg.org/check/33651/ :( I am not capable, I am
 afraid, though I did it in dpx patch.
