I've started using it for dxva, and it does seem to work there. One rather
annoying but thou..
If ffmpeg is compiled without dxva/vdpau support. get_format will currently
still ask for the dxva/vdpau pixformat's, fooling the app that those can be
Fixing it is not entirely straight forward as for example vaapi supports
multiple codecs, which can be disabled separate. And currently all of those
formats use a single list for which pix_fmt's the have
