17Description
18===========
19
20These four pixel formats are raw sRGB / Bayer formats with 14 bits per
21colour. Each sample is stored in a 16-bit word, with two unused high
22bits filled with zeros. Each n-pixel row contains n/2 green samples
23and n/2 blue or red samples, with alternating red and blue rows. Bytes
24are stored in memory in little endian order. They are conventionally
25described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an
26example of a small V4L2_PIX_FMT_SBGGR14 image:

28**Byte Order.**
29Each cell is one byte, the two most significant bits in the high bytes are
30zero.
