This means that, a plain `vainfo' call on your nuc3 system will yield
the same output. If so, this would mostly report an additional error
like X11 display not available. This means that, if you have been
connecting to nuc3 with ssh, and that the remote host has X running,
the correct command would be DISPLAY=:0.0 vainfo, resp.
gst-discoverer-1.0. Otherwise, initialization of the VA driver, so
gst-discoverer-1.0 will fail finding out anything, unless you have a
SW decoder around (gst-libav).

However, there normally is correct support for headless displays. So,
if you have built gstreamer-vaapi with the VA/DRM backend too, and
your user belongs to the "video" group, or whatever has access to
/dev/dri/card0, this should fallback to that headless mode.
