Is Apple using the fixed-function HW or an OpenCL-based
implementation? I am wondering because most of the HW decoders I know
of (MFX for Intel, UVD2 for AMD, not sure for NVIDIA) can only decode
to NV12 for H.264... So, other formats would be GPU converted.
Xidorn's data shows something else though.
