I tought of a minimal way for now to get those things working in the complete concept. Ommitting all the 10 bpc surfaces and also only using 8 bit references is a quite a hacky approach. As I don't know of any hw decoder that really does those things in 10 bits, I thought it is enough to get the discussion started. Presentation is a good aspect I did not have in mind. > Best regards > Grigori > > >> In mesa it is currently handled with the already given profiles, see >> attached patch.
