19Description
20===========
21
22These four pixel formats are raw sRGB / Bayer formats with 14 bits per
23colour. Each sample is stored in a 16-bit word, with two unused high
24bits filled with zeros. Each n-pixel row contains n/2 green samples
25and n/2 blue or red samples, with alternating red and blue rows. Bytes
26are stored in memory in little endian order. They are conventionally
27described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an
28example of a small V4L2_PIX_FMT_SBGGR14 image:

30**Byte Order.**
31Each cell is one byte, the two most significant bits in the high bytes are
32zero.
