It is hard to find information about it, as most answers come from
a pasting of the results of vainfo command.
However, I could have determined (through driver code for example)
that it is related to Multiview Video Coding which sounds good for
stereoscopic videos I would like to create.

Ok, I will go there when I have some time.

Nope. It is mainly based on this observation on the
VAProfileH264StereoHigh profile.
Thus I wondered if I could use it to accelerate encoding of my
stereoscopic videos (or with nvenc, whatever).
