The VDPAU driver for VAAPI[1] is unmaintained, and many use-cases fail. Thus
gstreamer-vaapi has a white-list of drivers[2] that can work with, and
va-vdpau-driver is not in that list. That's why `gst-inspect-1.0 vaapi` shows
zero elements.

If you still want to try it, export the variable GST_VAAPI_ALL_DRIVERS=1, but
you are on your own.
