/* 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'.
