Hi,
Mapping tables between superblock -> macroblock <-> fragment aren't needed and only make 4:2:2/4:4:4 support harder. It also allows eliminates any need for the internal validity checks for these mapping arrays.
This (surprisingly to me) doesn't significantly affect speed, it seems to be at best .1% faster overall.
