- Guidelines for Linux4Linux pixel format 4CCs
- ============================================
- Guidelines for Video4Linux 4CC codes defined using v4l2_fourcc() are
- specified in this document. First of the characters defines the nature of

- other three characters depends on the first one.
- Existing 4CCs may not obey these guidelines.
