  We explicitely disable support of hardware-accelerated codecs from
ffmpeg in gst-ffmpeg. There isn't a unified way to forward the
va-api/vdpau/hw specific information between ffmpeg and gstreamer.

  In order to have proper VAAPI acceleration support in GSTreamer, we
would need some gst-specific plugins.
