no, Youtube always reencods since they are targeting not high quality with
AV1 but lower bitrate. So RGB will have to be reencoded to YCbCr, I
suppose.

Thanks for the clarification and the patch.
By YouTube being affected I mean that an uploaded video (whatever it's
reencoded to) has wrong colors.
