Hi Daniel!

No, I don't much familiar with VDPAU nor VAAPI. It's seems that ffmpeg
support for these methods isn't sufficient for using it - bino must be
aware of using VDPAU or VAAPI too, see [1].
What for CUDA - I'm not a specialist too, but I think this method can be
implemented in ffmpeg-only style, but I don't know such attempts either.
