32-bit formats are accepted and produced by all units except the MPEG-2 decoder.
Packed YUV 4:2:2 formats store two horizontally adjacent pixels into two 16-bit units.
Each pixel has an individual luminance (Y1 for the left of the pair, Y2 for the right of
the pair). There is a single U and V value associated with the pair. The U and V
values are taken from the same spatial position as the Y1 sample
There are two variants of packed YUV 4:2:2: the Microsoft ‘UYVY’ format and the
Microsoft ‘YUY2’ format. The big-endian view of the YUY2 format is identical to the
Power MacIntosh ‘2vuy’ format.

successive 16-bit units contain a pair of pixels. This view is independent of system
endian mode.
