This Plex server had hardware transcoding working for the last few years. It stopped working a few weeks after updating to Proxmox 9.1.9. I can see the iGPU on the Plex server and I did chmod 777 /dev/dri/card0 and /dev/dri/renderD128 (just to troubleshoot) which did not seem to fix it. Doesn’t work with HDR tone mapping enabled or disabled.
I see this in the logs but video doesn’t play
