Hi.

I noticed that after the Mesa upgrade from stable 19.0X to 19.1rc when trying
to play MPV video with VAAPI it crashing MPV with this error:

Violation of memory protection (memory dump) <- (last line translated)

It worked fine on Mesa 19.0X, it began crash after upgrade to Mesa 19.1rc2 and
19.1rc3.
Trying libva 2.4.0 and also libva 2.4.1 - same results.

MPV crashing at default launch options. Crashing also with --vo=vaapi or
--vo=vdpau.
Not crashing with --vo=gpu or --vo=xv

Worth to add other video players like VLC not crashing wit VAAPI. Only MPV.

Details:
Linux OpenMandriva Lx 4 x86_64
Kernel 5.1.5
Mesa 19.1rc2/3
libva 2.4.0/2.4.1

Tested on two computers with R600, one PC with Radeon HD5850 and notebook with
Radeon HD5650m.
