Category: Proxmox

Important: This is for use with Debian 12 (BookWorm) / Proxmox (8.2.7).

Run these commands on both the proxmox host and Emby CT. I have this method working on successfully on both a N100 iGPU and Sparkle Intel Arc A310 ECO

nano /etc/apt/sources.list

add the following

non-free firmwares
deb http://deb.debian.org/debian bookworm non-free-firmware

non-free drivers and components
deb http://deb.debian.org/debian bookworm non-free

Install the following
apt update && apt install intel-media-va-driver-non-free intel-gpu-tools

cd /dev

Use the following command to list all files and folders in the current directory

ls -lah

Make a note of the numbers in bold you see for dri / fb0 (If it exists)

drwxr-xr-x 3 root root 100 Aug 30 20:56 dri

crw-rw---- 1 root video 29, 0 Aug 30 21:19 fb0

Navigate to the dri folder using the following command

cd /dev/dri

ls -lah

Make a note of the the number in bold for renderD128

crwxrwxrwx 1 root render 226, 128 Aug 30 21:19 renderD128

Now we will add the numbers that were noted down to our CT config on proxmox for Emby – Important amend the command below with your CT’s ID number shown the proxmox webgui (Example Below) Mine is 3006

Now open your CT’s config files on your Proxmox host.

nano /etc/pve/lxc/3006.conf

Add the following lines to the file and save using CTRL + O and then enter.
lxc.cgroup2.devices.allow: c 29:* rwm
lxc.cgroup2.devices.allow: c 100:* rwm
lxc.cgroup2.devices.allow: c 226:* rwm
lxc.mount.entry: /dev/fb0 dev/fb0 none bind,optional,create=file
lxc.mount.entry: /dev/dri dev/dri none bind,optional,create=dir
lxc.apparmor.profile: unconfined

Adding Persistent GPU Permissions on proxmox host so the GPU is accessible to the CT after reboot.

nano /etc/udev/rules.d/99-renderD128-permissions.rules
KERNEL=="renderD128", MODE="0777"

udevadm control --reload-rules

udevadm trigger

How to Test?

Run the following command (This is basically task manager for your GPU)

intel_gpu_top

You can also check the Emby admin webpage under Server > Transcoding. If you see your GPU and a list of Hardware Decoders its likely working. Test forcing something to Trancode by change the bitrate and monitor the CPU usage and using intel_gpu_top see if there is any ffmpeg processes running on the GPU
