/*
|
|
* In order to interpret these pixel format namings, please take note of these
|
|
* conventions:
|
|
* - The Y8_U8__Y8_V8_N422 and U8_Y8__V8_Y8_N422 formats are both packed formats
|
|
* that have an interleaved chroma component across every two pixels. The
|
|
* double-underscore is a separator between these two pixel groups.
|
|
* - The triple-underscore is a separator between planes.
|
|
* - The 'N' suffix is a delimiter for the chroma decimation factor.
|
|
*
|
|
* As examples of the above rules:
|
|
* - The Y8_U8__Y8_V8_N422 format has one 8-bit luma component (Y8) and one
|
|
* 8-bit chroma component (U8) in pixel N, and one 8-bit luma component (Y8)
|
|
* and one 8-bit chroma component (V8) in pixel (N + 1). This format is
|
|
* 422-decimated since the U and V chroma samples are shared between each
|
|
* pair of adjacent pixels per line.
|
|
* - The Y10___U10V10_N444 format has one plane of 10-bit luma (Y10) components,
|
|
* and another plane of 10-bit chroma components (U10V10). This format has no
|
|
* chroma decimation since the luma and chroma components are sampled at the
|
|
* same rate.
