According to Intel's docs on libva, the rext HEVC profile is supported for
decoding in your libva build, yet it fails on your end (DG2).
I'm referring to the notes on
https://github.com/intel/libva/blob/master/va/va_dec_hevc.h#L242, implying
that this is tied to VAProfileHEVCScc* profile entry-points.
The failing video signals HEVC rext as it's profile.
Perhaps an intel developer can take a look at this and assist?

Copying some of them in the thread.
