Xpenology - No Hardware Transcoding

[MikeTFresh]

Hi @ChuckPa (or anyone that can help!),

I’m running Plex on Xpenology and I’m unable to get Plex to ‘hw’ transcode. Seems like Plex is not recognizing my hardware and quicksync. I’ll list specs and info below.

CPU: intel i7 12th 12700k
Plex Version: 1.40.3.8555
DSM Version: DSM 7.1.1-42962 Update 6
Model Name: DS920+
Kernel Release: 4.4.180+

Notes:
• PMS > Settings > Transcoder > ‘Use hardware acceleration when available’ AND ‘Use hadware-accelerated video encoding’ settings are indeed enabled.
• I noticed that the directory /dev/dir/ does not exist, so I’m unable to modify anything there.
• I also have tried adding "VaapiDriver=‘i965’"to the Preferences.xml file in File Station > PlexMediaServer > AppData > Plex Media Server.

Have you encountered this issue before and do you have any suggestions? Could this be due to any updates? Any help will be appreciated! I’ve been seeing a lot of mixed answers.

Thank you so much!

I noticed that the directory /dev/dir/ does not exist, so I’m unable to modify anything there.

/dev/dri (not dir)

From a DS918+

Suggestion:

1. Remove “VaapiDriver=‘i965’” from preferences.xml.

2. Ensure Plex is configured for debug, not verbose, logs.
   Settings → Server_Name → General + Show Advanced
   

   

3. Stop Plex Media Server. Wait 30 seconds.

4. Start Plex Media Server. Wait 3 minutes for Plex to start & log everything.

5. Play something that transcodes for ~20 seconds.

6. Stop playback, pull log files (Settings → Troubleshooting), and upload the logs to the thread. Drag the entire ZIP file into the message window. It will insert at the cursor location.
