[v6.8.0-rc4] Intel QuickSync still broken

  • Closed
  • Annoyance

I have set up my server to be a low power consumption base for my Plex media server.

Upon upgrading to the v6.8.0 Release Candidates (starting with the first one) hardware transcoding through Plex is broken for me.

 

Symptoms are:

  • Stream appears to be started, yet video is not progressing
  • Instead of an image the screen remains black
  • If at all, the stream starts extremely stuttery and (I kid not) in a somewhat low resolution of 16x16px (estimated)
  • If I turn of hardware transcoding in Plex, streaming is possible again (hogging my low power CPU).

 

Where is was previously able to serve multiple 1080p x265 streams my server now barely handles a few 720p transcodes..

 

It was previously working fine with the CPU listed in my signature. Only required modifications to Unraid were these lines in the go script:

modprobe i915
chmod -R 777 /dev/dri

The encoding device is showing up as previously.

 

There is no informational log entry in the Unraid, Plex Docker or even Plex debug logs - hence none are attached.

This post is mainly to raise awareness for the issue, since my previous comments achieved no response.

 

Is this happening to anyone else? Any idea how to fix this or break the issue down? Any help is highly appreciated! I am most willing to assist in getting this fixed.
