Use the video's profile. Alternatively, you can try to setup the
AVCodecContext to do vdpau decoding, which will fail if the video is
9/10 bit (it will try to fallback to software decoding, which you can
detect). But note that there are 8 bit videos which can't be decoded
with most hw decoders, so the profile should be checked too.
