Make it HWACCEL instead of VDPAU, it seems generic enough, with the
small change you pointed already seems good to me.
The hardware (NVDEC, AMD UVD, etc) is the same regardless of which
interface is used to talk to it (VDPAU, DxVA, ...), and thus the concept
should be portable. I can rename it if you want and then move it
avcodec.h.
*But* there are currently no generic ways to set hardware acceleration
flags to an AVCodecContext...
