I have been trying to get QuickSync working in Linux and am not having any luck.

I've tried lots of stuff, and probably to much to try and type it out.
I've tried the following distro's
Ubuntu 24.10 (Kernel 6.11)
Debian Testing (Trixie) (Kernel 6.11.4)

I think it may actually be working

#

So while Quick Sync is working, it not working as well as I thought...

#

Trying to troubleshoot it

#

am I using the xe driver, is there a way to switch to the driver in linux, would it make a difference...

#

You can switch the kernel driver using kernel parameters, you can see which one is in use with lshw

#

The older kernel driver is i915, the newer is Xe (not sure if its still experimental though)

#

Do you have the latest vaapi and other intel packages?

#

I had Grok 3 just run me through forcing it to use xe and build the mesa support KMD lol

#

intel_gpu_top does not work anymore

#

➜ ~ intel_gpu_top -l
No device filter specified and no discrete/integrated i915 devices found

#

this is a headless server

#

I need the gpu for video hw accel in plex

#

plex does not use HW accel anymore after forcing the xe driver

#

Grok 3 had me update grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet i915.force_probe=!7d67 xe.force_probe=7d67"

#

hardware accel transcode worked when the i915 driver was loaded, but I was getting buffering like every 30 - 90 seconds
