1 Guidelines for Video4Linux pixel format 4CCs
2 ============================================
4 Guidelines for Video4Linux 4CC codes defined using v4l2_fourcc() are
5 specified in this document. First of the characters defines the nature of
6 the pixel format, compression and colour space. The interpretation of the
7 other three characters depends on the first one.
9 Existing 4CCs may not obey these guidelines.
14 The following first characters are used by raw bayer formats:
16 - B: raw bayer, uncompressed
17 - b: raw bayer, DPCM compressed
21 2nd character: pixel order
28 3rd character: uncompressed bits-per-pixel 0--9, A--
30 4th character: compressed bits-per-pixel 0--9, A--
