Plex HW Transcoding in TOS 5.1

I haven't been able to get hw transcoding working on Plex since upgrading to TOS 5.1. I was on TOS 4.x before and it worked just fine. As a workaround, I have installed the official Plex docker image and hw transcoding is working just fine after passing through /dev/dri - so it doesn't look like a kernel issue but something is wrong the userland/libraries in TOS.

Model: F5-221
TOS: 5.1.24
Plex Media Server: 1.3.1

You need to add the plex user to the media user group and then give permissions to the media user group.

plex user is in group 6 which is media. Is this what you mean?

Code: Select all

# grep plex /etc/passwd
plex:x:1009:6:TOS App User:/home/plex:/bin/bash

Issues with hardware transcoding are being fixed. Need to wait for the plex team to update the app.

You can try setting GUID and PUID to 0 in variables.

The new package released by plex has not solved the issue of hardware transcoding.
Please consult the plex team for specific progress.

Same issue, transcoding isn't using hardware and often actually crashes my Plex app. So is this a TOS 5 issue now? I see no mention of it at all on the Plex forums.
