I don't think we should expose VDPAU in transcoding pipeline, at least not 
until/unless it gets window-less bindings. There's no need to go all meta 
here. If you want to transcode on NVIDIA hardware, use NVDEC.

But anyway, we need a different capability to instantiate VLC decoder devices 
out of "thin air" rather than out of a VLC window.
