After upgrade server,can't use hw trancoding

I have been trying to find a way to diagnose further.
I apologize for the language problems I do not understand.

  1. Stop Plex
  2. Edit Preferences.xml
  3. add VaapiDriver="i965" before closing />. A space in front is needed.
  4. It will look like this: VaapiDriver="i965" />
  5. Start Plex

This disables the iHD_drv_video.so driver.

You may also delete the driver and restart Plex if you prefer.

As for the -10xxx CPUs, The Linux kernel does not have the HWE for the i915 to communicate with the QSV ASIC.
