Different VA drives might have different definitions for RGB32 color formats because different bit interpretation. Sadly the specification doesn't clarify these interpretations. So VA users have to figure out what's the correct mapping with it's rendering color format definition. This patch aims to fix the static map structure after the VAImageFormats are queried. There is another static map with the different interpretations of the RGB32 formats, and compare them with the given VAImageFormat, then with the GStreamer color format, update the mapping table. Finally, some RGB32 color formats were added. Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/2129>

/* 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
|
|
* need to correct the mapping form VA video format to GStreamer
|
|
* video format in both manners.
