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 |
|
the pixel format, compression and colour space. The interpretation of the |
|
other three characters depends on the first one. |
|
|
|
Existing 4CCs may not obey these guidelines. |
