Skimmed over this in my first pass.
Do we really want to be returning true here if the driver doesn't
support encoding/range? It's probably not a good idea to really expose
YUV formats with them so it might be best to just assert here instead.
The rest of P1+P2 lgtm. I don't see P3 but that still only needs the
title fix.
