Comment (by Diederick Niehorster):

 Thanks, i have updated the patch, just correcting what i already based on
 your comments. Annoyingly, it seems e.g. BT.2020 is exposed by
 mediafoundation, but not things accessible through dshow... Still better
 have this than nothing.
 Is it possible to also figure out AVColorSpace from these fields? The
 documentation is more complete here: https://docs.microsoft.com/en-
 us/windows/win32/api/dxva2api/ns-dxva2api-dxva2_extendedformat, which may
 help. Exact same fields otherwise.
