Hi, vlVaQueryImageFormats (or vlVdpVideoSurfaceQueryGetPutBitsYCbCrCapabilities) implementation call pscreen->is_video_format_supported with input profile equal to PIPE_VIDEO_PROFILE_UNKNOWN.
Problem is that "nouveau_vp3_screen_video_supported" or "rvid_is_format_supported" will returns several formats: NV12, YV12, YUYV, UYVY, BGRA because it fallback to call vl_video_buffer_is_format_supported. Whereas these 2 functions would have return PIPE_FORMAT_NV12 if input profile is not PIPE_VIDEO_PROFILE_UNKNOWN. So I wonder if nouveau_vp3_screen_video_supported should just return PIPE_FORMAT_NV12 in all cases. (same for rvid_is_format_supported) Am I missing something ? What is the purpose of checking PIPE_VIDEO_PROFILE_UNKNOWN : http://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/drivers/nouveau/nouveau_vp3_video.c#n486 and http://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/drivers/radeon/radeon_video.c#n323 ?
