Specify device to gstreamer VAAPI

[RiccardoCagnasso]

I made a couple of tests. 
Using vaapi i965 driver on a pc with a Nvidia quadro connected to the
monitor, i need to add --display=drm to vainfo to read the capabilities of
the graphic card. No --device seems to be required. But gst-launch filesrc !
demux ! vaapidecodebin ! vaapisink display=drm doesn't really work (creates
a windows but no video on it)

With vaapi iHD driver (https://github.com/intel/media-driver) vainfo doesn't
require --display=drm (odd). gst-launch filesrc ! demux ! vaapidecodebin !
vaapisink display=drm or gst-launch filesrc ! demux ! vaapidecodebin !
vaapisink doesn't work (doesn't create a window) but gst-launch filesrc !
demux ! vaapidecodebin ! xvimagesink works, albeit choppy on anything more
than 1080p.

I'm confused.
