Is this stopping hardware transcoding? From what I can tell (i’m pretty new to troubleshooting these things) plex says it’s starting a transcode on my gpu but it just isn’t. I’ve verified a dozen different ways that it has access to all of the files it needs and the gpu is detected and available in the docker container. I’m out of ideas on how to get this working. Any assistance would be appreciated. If I should start a new thread for this issue just lmk.

I moved your post here. When you look in the [server logs,](https://support.plex.tv/articles/200250417-plex-media-server-log-files/) 1. The GPU card is detected ```auto Aug 10, 2025 19:14:07.150 [22412873657144] DEBUG - [GPU] Got device: NVIDIA TU104 [GeForce RTX 2080 SUPER], nvidia@unknown, default true, best true, ID 10de:1e81:1462:c724@0000:2b:00.0, DevID [10de:1e81:1462:c724], flags 0xe8 ``` 1.

AI said I should change the group to video but that didn’t seem to fix it. Below is what I’m at currently, gotta get to work but I can take a look when I get off if you have any suggestions. root@UnraidServer:~# ls -la /dev/dri total 0 drwxrwxrwx 3 root root 100 Aug 10 17:56 ./ drwxr-xr-x 18 root root 3720 Aug 10 18:03 ../ drwxrwxrwx 2 root root 80 Aug 10 17:56 by-path/ crwxrwxrwx 1 root video 226, 0 Aug 10 17:56 card0 crwxrwxrwx 1 root video 226, 128 Aug 10 17:56 renderD128 root@UnraidServer:~# grep video /etc/group video:x:18:sddm [Plex Media Server Logs\_2025-08-11\_05-43-55.zip](https://forums.plex.tv/uploads/short-url/9MZligymhA8Zma67zkmcrBTEGG3.zip) (2.6 MB) ![image](https://global.discourse-cdn.com/plex/original/4X/4/c/b/4cb3c5002c081343af5a5ff246fe6cc2ffdcaf71.png) ---

As a test , make the container privileged. (That’s how I run it) ---

I think I fixed, I wasn’t using the official plex app on unraid, I stumbled across that and it worked right away. Not sure what the difference was, it was the same plex version and same setup on my end but it is working now so we’re all good. Thanks for the assist. ---
