Server Version#: 1.19.5.3021 Player Version#: Plex Web 4.37.1 I recently acquired a Quadro P400 and turned on hardware transcoding with NVENC. This works, and playing HEVC files in Plex Web (Firefox or Chromium) sucessfully transcodes them to h264 using the GPU: https://fb.hash.works/ldQuTY/ Howe…

[image] hashworks: Also we have today’s 450.57 in the Arch staging repository, I’ll try it out later. Bug is gone with today’s linux 5.7.8 and 450.57 from the Arch testing repo, works just fine! I’ll mark this as a solution then. @ChuckPa can you add nvidia 440 as buggy to the wiki page ?

You do realize, HW-anything , in a VM, is always a risky proposition ? I don’t doubt there’s something not right but I am not equipped to recreate it. I don’t have proxmox on anything nor am I familiar enough with it to have confidence in what I do. (I’m only now getting ESXi up and runnin…

Understood, but I’m not convinced this is a purely HW transcoding issue, since it seems to work 100% fine in Plex App for Windows, or Plex App on Android - it seems more a Plex Web player issue in the browser, maybe with how Plex Web is calling transcoding/HW transcoding specifically. And, as menti…

@ChuckPa , I still reproduce this problem on 100% bare metal. Android app can request transcodes fine Roku transcodes fine SyncLounge (html / web based) transcodes fine Plex Web consistently does not transcode Here is my /dev/dri ls -al /dev/dri/ total 0 drwxr-xr-x 3 root root 100 Apr 26 …

mcapplbee, thanks for confirming this is an issue on bare metal as well! I also forgot to mention in my very last response, but did earlier, that it works with Ubuntu 18.04 in the exact same proxmox/vm config, so it didn’t seem like a straight virtualization issue - good that we have full confirmat…

Been struggling with this issue myself. As reported by everyone else, transcoding on clients other than plex web is fine. But plex web in chrome/firefox has issues. It does however seem to function fine within Microsoft Edge however! I had started my own thread before finding this, but bumping this…

I keep checking back on this. Every time I do a kernel upgrade, nvidia driver update or plex update I can reproduce the problem consistently. My system is simply Ubuntu 20.04.2 LTS on bare metal with a P2200 GPU. We have a lot of users with this problem still @ChuckPa Do you need more information …

PMS sends sigkill (not sigterm which is more graceful but not guaranteed) when the STOP message from Plex/Web arrives. I wish I had an Nvidia GPU-capable machine here so I could be hands-on with this. What I have found is there’s a version of the Nvidia drivers which does cause problems The min…

I rebuilt my VM and took some snapshots and started testing this morning. The driver versions available via repository are 390, 418, 450, 460, and 465. I didn’t test with 390 since you said API version requires 418.30 min. Installed 418 from repo, which installed 418.197.02 per nvidia-smi. Plex …

I can no longer reproduce the problem. I have since rebuilt my NAS with brand new hardware and OS (arch). It’s now on an X399 motherboard with a 2nd gen threadripper. It still has the p2200 and plex web can transcode fine. My original NAS is not in working order and would not be easy to swap par…

I have had HW transcoding off for a while now, but at the time, I too started 2 topics (1,2). Exact same issue, cannot start the transcode in the web client but I could do it on my phone and my TV’s.
