Nvidia transcoding stopped working in Plex docker after upgrading to 6.10

[Raki72]

I just realized that in my Plex docker container (plexinc/pms-docker) the transcoding is not using my Nvidia graphics card anymore. I didn't change anything in the configuration or so. The only change was to upgrade from the latest RC to the final 6.10 Unraid version. But I am not sure, if the problem already occured with one of the RCs.

 

Anyway, the problem is that the Plex transcoder is not using the dedicated graphics card anymore, but falls back to CPU coding.

 

I can't find any error message, so I tried to identify the problem with the following steps:

- changed the Nvidia driver from v510.73.05 to v515.43.04, v495.46 with reboot and back - no impact

- installed binhex/arch-plexpass and repeated the Nvidia driver changes there - no impact

 

Any idea how I could solve this problem? Or anyone having the same problem?

 

Thanks for any feedback. 🙂

Having the exact issue myself, plex loads but trying to get HW transcodes to run seems to lock up, some have posted to uninstall and reinstall the nvidia driver then reboot which im trying now

I already reinstalled the Nvidia drivers and rebooted the server - didn't help.

 

Please let me know, if you find something.

i ended up reverting back to 6.9 of unraid - i spent a few hours with little success so I just gave up for now.

HW encoding works again. All I did was to switch off the server and switch on. No clue, why this changed anything, but now its working again. ⁉️

Glad its working for you, i might leave it a little and see, everything running smoothly at the moment and didnt need an immediate reason to update, but will retry eventually

Did anyone here ultimately solve this problem?  I have the exact same issues on my GTX 1070 and I'm now on 6.11.5.  Plex reverts to software instead of HW transcoding.

I believe I am having the same issue. I notice now that the GPU stat doesn't show Plex utilizing the encoding/decoding process. Nothing else changed with the system outside of the latest OS updates. Is there a way to validate if HW decoding is being still be used?

having the same issue , maybe because of nvidia driver update ? i tried uninstalling driver & plex both , restarted multiple times with no success , any idea how to go back to an older driver ?
