/* The HM12 format is used in the Conexant cx23415/6/8 MPEG encoder devices.
It is a macroblock format with separate Y and UV planes, each plane
consisting of 16x16 values. All lines are always 720 bytes long. If the
width of the image is less than 720, then the remainder is padding.
The height has to be a multiple of 32 in order to get correct chroma
values.
It is basically a by-product of the MPEG encoding inside the device,
which is available for raw video as a 'bonus feature'.
