Apparently mesa 22.3.0 has updated the egl headers, and eglplatform.h now
contains commit
3670d645f4
after which xlib headers don't get included by default anymore but are
dependent upon whether USE_X11 was defined.
This breaks headless builds of gstreamer-vaapi because we always define
an internal define USE_X11 as either 1 or 0.
Change these defines to GST_VAAPI_USE_XYZ instead to avoid this.
Fixes #1634

|
|
*
|
|
* 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.
