VDPAU VdpOutputSurface and YCbCr
I would like to ask if it's possible to fetch VdpOutputSurface pixel data in VDP_YCBCR_FORMAT_YV12 format, or in any other VDP_YCBCR_*. In other words - does the VdpVideoMixer has possibility to output YCbCr format or it just performs color space conversion and works on RGB then?
I would like to benefit from hardware decoding, deinterlacing, scaling and even overlaying using VDPAU and I would like to feed another codec with output from VDPAU. It accepts only YUV.
Of course I can perform RGB->YUV color space conversion on my own, but it would be nice if I could skip this step for higher performance of overall system.
Thanks and regards.
