Point taken, it's unstable API. And gstreamer-vaapi has done a good job
catching that incompatibility ;)

My worry about these tweaks per specific versions is that we can lose control
(even more :)) of the used API, if we don't draw a line. At least in upstream.

Nevertheless, if we are going to take that path, we should do it a code level,
guarding the usage of that API (which now is only for logging) for that libva
version. Dunno.
