Untabifying header file. The logging category was moved from the plugin generic category to the display category. It can argue that video formats hacks are display dependant. Added validations for input parameters. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2048>

|
|
* For MSB, there is no ambiguity: same order in define, memory and

|
*
|
|
* RGBA is RGBA in memory and RGBA with channel mask R:0xFF0000

|
* 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.
