 solved this: mfxFrameInfo::Shift (a bool) indicates whether the 10 bits
 are stored as the least or most significant bits in the whole 16 bits. HW
 uses the most significant bits and SW the least. The tutorials scale the
 values for HW before writing to disk. Maybe this shift option can be added
 as a bool in ffmpeg? This option is needed by Intel hevc plugins with
 P010le colorspace
