Plex LXC Container Hardware Transcode help

[Dataninja]

I'm newer to Proxmox and have been spinning my wheels for a couple of days trying to get HW to work in Plex LXC container. I've scoured the forums and the web, but seem to be coming up short.

I've tried multiple setups including VM's but hitting can't seem to get it to work.

Here's my latest config on my Minisforum nab6 PC with 12650H CPU(VT-D enabled).

• Plex in LXC container using the script from tteck.github.io
  • Advanced setup to use Ubuntu 20.04
  • 20 GB drive space
  • 8gb of ram
  • 4 Cores
  • Installed on a ZFS I created on an NVME (Storage) and not on local lvm (proxmox host install)
  • enabled SSH

Proxmox Host:

/etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on"

ls -l /dev/dri (same thing shows in the container):

drwxr-xr-x 2 root root         80 Apr 24 10:43 by-path
crw-rw---- 1 root video  226,   0 Apr 24 10:43 card0
crw-rw---- 1 root render 226, 128 Apr 24 10:43 renderD128

I'm not sure what else I'm missing

The problem is that you wont be able to use plex with hardware decoding running in a container.
You need to create a VM and go to the hardware tab to add the GPU.

Not true. My Plex is running in an LXC and seems to be doing hardware acceleration ok.
