Comment 130 for bug 1816497

>> Also, I guess you have Nvidia GPU?

Yes. My Thinkpad T460p has two video card, one is nvidia (not not helpful for video decoder/encoder), and another is the intel video card.

>> You may confirm this with "snap run --shell chromium", and then contrast "vainfo" with "LIBVA_DRIVERS_PATH=/snap/chromium/current/usr/lib/x86_64-linux-gnu/dri/ vainfo".

It is an interesting result:

snap run --shell chromium
To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details.

Strang, it finds the proper driver, so the following line impact this in the run time.

My native working environment :

vainfo: VA-API version: 1.14 (libva 2.14.0), but snap

vainfo: VA-API version: 1.14 (libva 2.6.0)

Is there a way to solve this?
