Which version of gstreamer-vaapi?

We have changed a lot gstreamer-vaapi recently in particular when downloading
the images from GPU to CPU. I recommend you to use the release 1.10.2. But
still there are rough edges.

The first question would be why do you have to export this variable? libva
should be able to detect the first available driver.

The second question is what do you mean with "don't play"? nothing is shown?
is shown badly?

In the release 1.10 we added a whitelist to block, precisely, the vdpau-va
bridge backend which is undermaintained, and buggy. So, if you are using this
release, the vdpau driver is bailed out and the software decoders are used as
fallback.

Most probably, gstreamer-vaapi in this case.
