QNAP HW transcoding stuttering

I have an interim workaround which works well provided the video bitrate is < 90 Mbps.

  1. PMS 1.19.5 for QNAP now provides direct access to Preferences.xml in the “PlexData” share in File Station.
    -or-

  2. Install / use PMSLibShare

  3. Using a Linux (not Windows) text editor (QNAP text editor is recommended), Add VaapiDriver="i965" before the closing /> at the end of Preferences.xml. Put a space before and after this setting.

It will appear as: VaapiDriver="i965" />
