/* XXX: RGB32 LSB VAImageFormats don't map statically with GStreamer
|
|
* color formats. Each driver does what they want.
|
|
*
|
|
* 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,
|
|
*
|
|
* 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
