Can't say much except:
1. It looks like we'll have NxM mapping implementation, and I question
   whether they really should exist as ifdef mess in the individual
   hwcontext impls, instead of a more structured approach (like one
   soruce file per N-M mapping).
2. ff_vaapi_fourcc_from_pix_fmt() is also funny - sure that we
   shouldn't have a more general public format mapping API like I
   suggested once with a patch?
