- V4L2_PIX_FMT_SGBRG12
- V4L2_PIX_FMT_SGRBG12
- V4L2_PIX_FMT_SRGGB12

	<title>Description</title>



	<para>The following four pixel formats are raw sRGB / Bayer formats with

12 bits per colour. Each colour component is stored in a 16-bit word, with 6

unused high bits filled with zeros. Each n-pixel row contains n/2 green samples

and n/2 blue or red samples, with alternating red and blue rows. Bytes are

stored in memory in little endian order. They are conventionally described

as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example of one of these

formats</para>



    <example>

	<para>Each cell is one byte, high 6 bits in high bytes are 0.
