* For MSB, there is no ambiguity: same order in define, memory and
* CPU. For example,
*
* RGBA is RGBA in memory and RGBA with channel mask R:0xFF0000
* G:0x00FF0000 B:0x0000FF00 A:0x000000FF in CPU.
*
* For LSB, CPU's perspective and memory's perspective are
* different. For example,
*
* RGBA in LSB, from CPU's perspective, it's RGBA order in memory,
* but when it is stored in memory, because CPU's little
* endianness, it will be re-ordered, with mask R:0x000000FF
* G:0x0000FF00 B:0x00FF0000 A:0xFF000000. In other words, from
* memory's perspective, RGBA LSB is equal as ABGR MSB.
*
* These definitions are mixed used all over the media system and we
* need to correct the mapping form VA video format to GStreamer
* video format in both manners, especially for RGB format.
