Formats map is instantiated at the end of the display instantiation. The problem is the Wayland display which looks for a format in a callback, before the map is populated. If user compiles gstreamer-vaapi with DRM support, the map is populated with a DRM display at GStreamer plugin registration. But if not, or a VA driver is not available, the plugin will try with a Wayland driver, which cause the NULL de-reference. Nevertheless, in the case of no DRM support, and if the Wayland display doesn't get a reply from the format conversion is not a problem. So the solution is the trivial one, check if the format map is already populated before de-reference it. Fixes: #977 Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1606>

|
|
*
|
|
* 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.
