[Bug 106519] Is it normal that the 4K video on the Vega 56 GPU played with loud turbine noise, 200% load of the desktop Core i7 CPU and at the same time playable with jerks and dropping frames?

Alex, 

I noticed that VAAPI does not work in X11 clients, and the output of vainfo
under the Xorg session gives the following result:

$ vainfo 
libva info: VA-API version 1.2.0
libva info: va_getDriverName() returns -1
libva error: va_getDriverName() failed with unknown libva
error,driver_name=(null)
vaInitialize failed with error code -1 (unknown libva error),exit

What is this problem here?
