[Libva] [PATCH] Add R8G8B8A8 and A8Y8U8V8 RT format definition for video process.

[Li, Xiaowei A]

Jonathan,

   Thanks for your correction and suggestion, indeed, I can use YUV444 as the RT format for A8Y8U8V8 and add RGB32 for R8G8B8A8 in video process.

Thanks,
Xiaowei

Xiaowei,

RT format is meant to convey sampling ratios of the components, and VASurfaceAttribPixelFormat is used to indicate pixel formats supported by the implementation or preferred by the application. In the case of A8Y8U8V8 and R8G8B8A8, these are considered pixel formats (which are defined as fourcc codes) and not RT formats. We do need to add a couple of RT formats for RGB such as:

#define VA_RT_FORMAT_RGB32 0x00010000
#define VA_RT_FORMAT_RGB16 0x00020000

Regards,
Jonathan
