IIRC, Matthieu has a patch I was about to include yesterday but I have
not tested it yet. This would require GStreamer >= 1.2 and VA driver
that efficiently supports  vaDeriveImage(), e.g. Intel HD Graphics
hardware. Otherwise, this kind of pipeline provides too much overhead
that I don't want to expose that by default.

If vaapisink doesn't have the desired function, then the proper thing
is to fix it there first. In order of efficiency (power and
performance), we have vaapisink > { cluttersink, glimagesink } >
xvimagesink.

Gwenole.
