VA-API video decoding doesn't work for Chromium browser with VA-API support
patches.

It works perfectly fine with Mesa 17.3.9: https://imgur.com/tMSKtsb
But totally broken with Mesa 18.0.3: https://imgur.com/xVGQDhB

My system is CentOS 7.5, custom built kernel 4.14.32 (longterm).
Video adapter is ASUS Radeon R9 Fury 4GB.

Mesa packages is also built by me.
libdrm version 2.4.91.
LLVM version 6.0.0.
libva version 0.40.

There isn't any errors reported by Chromium or libva or in dmesg.

Also I found in discussion of chromium-vaapi (for Arch) a user with AMD Radeon
have very same problem with Mesa 18.
Link to discussion:
https://aur.archlinux.org/packages/chromium-vaapi-bin/?comments=all
User name is digitalone.

Chromium built with VA-API patches is available in Ubuntu PPA or Arch Linux
AUR.

If it'll be needed I can upload my build of Chromium with VA-API patches for
CentOS 7 somewhere.
