Thanks for review. The main reasons for adding these two format are as follows: 1. For most HDR monitors, A2R10G10B10 is used for display format for rendering. So this format is important to do 10bit RGB rendering support in ffmpeg. 2. HW VPP can do both p010->a2r10g10b10 and a2r10g10b10->p010 with this patch, which can provide support for hw encode pipeline using a2r10g10b10 as input.
