Comment (by Balling):

 Replying to [comment:17 petr.diblik]:
 > IMHO the support of RGB and its variants in AV1 codecs should depend on
 [https://aomediacodec.github.io/av1-spec/av1-spec.pdf the AV1 spec]. I
 checked it and it seems to me that it's not supported. Could someone
 clarify pls?

 The keyword to search is MC_IDENTITY. MC_IDENTITY means RGB. Sigh.

 v3 of my patch.
