Hello,

I am trying to Passthrough my Intel UHD 630 iGPU to an Ubuntu 22.04 VM and configure Plex to use iGPU Hardware transcoding with a Docker container running on the Ubuntu 22.04 VM hosted on ProxMox.

My issue is Plex running on the Ubuntu 22.04 VM does not use Hardware Transcoding and CPU usage is still at 100% when transcoding. I am not sure how to proceed from here as it does look like the iGPU is passed through from the ProxMox host to the Ubuntu 22.04 VM but Plex within a docker container on the Ubuntu 22.04 VM does not use the iGPU for transcoding.

Here is what I have done, configs, & outputs. If you require any additional information, please let me know.
