Intel quicksync for plex lxc

[danaja]

I'm a newbie. I've installed proxmox on an hetzner box with a Xeon E3-1245V2 processor. All working (happy!).

I've see many tutorial on how achieve quick sync work on vm or lxc. Now i've a problem when i install the i965. If i check with vainfo i got:

# vainfo
error: can't connect to X server!
error: failed to initialize display

Anyone can help me listing all the step?

Thank you
