Subject: vda: add support for nv12 image formats

The hardware always decodes to nv12 so using this image format causes less cpu
usage than uyvy (which we are currently using, since Apple examples and other
free software use that). The reduction in cpu usage can add up to quite a bit,
especially for 4k or high fps video.

This needs an accompaning commit in libavcodec.
