Comment (by Diederick Niehorster):
>> 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.
Lets leave it as is, best guess i guess.
>> Also, fallback to primaries/trc and stuff already happens here:
https://github.com/FFmpeg/FFmpeg/blob/bc70684e74a185d7b80c8b80bdedda659cb581b8/libavfilter/vf_colorspace.c#L74
Best to keep it here anyway, many signals don't go through that filter?
>> Also, is P010BE signalisation is actually big endian or is that (as
Carl noted) actually little endian and dshow is just swapped??
Thats a question for the other patch, right? I have no clue, hope the
original submitter can chime in on that (e.g. by trying it out once
patches are in).
I haven't worked with this FATE thing before. Do both my patch here and
the other patch trigger changes in these hashes? Then i could do them both
at once. If my patch here doesn't, i'd hope to stay away from it ;)
Proof's in the pudding, i'll give it a try.
