FAQ 20: Bypassing the iHD video driver

Obsolete as of PMS version 1.21.0

Reference only

This still seems to be effective for some customers with low bitrates, LiveTV buffering, or DVR signal strength issues

For versions below 1.21.0
This shouldn’t be necessary but is until such time as Intel is able to fix the problem.
the best choice is to configure PMS to bypass it by editing your Preferences.xml file

  1. Install the Synology Text Editor (Required)
  2. Stop Plex
  3. Open File Station and navigate to Plex / Library / Application Support / Plex Media Server
  4. Right-click Preferences.xml and Open in Text Editor
  5. On the bottom line, scroll to the right.
  6. Bfore the closing /> type VaapiDriver="i965" .

It will appear as : VaapiDriver="i965" />
Preceding and succeeding space is required.

  1. Save the file
  2. Restart PMS

WARNING: REMOVE this preference when playing HEVC HDR encoded with Level 5.0 and above. The i965 initialization will fail. HW transcoding will fall back to SW and fail to transcode.
