Hardware Transcoding with Intel UHD Graphics 605 on Proxmox Privileged LXC - designingbeing - 2024-08-24

Jellyfin is giving the error "Playback failed due to a fatal player error" whenever I enable hardware transcoding.

I've followed the Jellyfin tutorial for Proxmox LXCs as best as I can and found a lot of threads on the subject but I'm not having success:

FFmpeg logs show 
Code:
No VA display found for any default device. 
Device creation failed: -22

The only thing that stands out to me is that
Code:
getent group render
gives different values on LXC=106, Proxmox Host=104. I'm not sure if this is even an issue, or what to do about it.


[*]Jellyfin 10.9.9
[*]Debian 12 running as a Privileged LXC container on Proxmox 8.2.4
[*]Installed via curl https://repo.jellyfin.org/install-debuntu.sh | sudo bash
[*]J5005 processor which iirc is Gemini Lake, based on Kaby Lake with Intel UHD Graphics 605

Did you pass the GPU into the LXC?

RE: Hardware Transcoding with Intel UHD Graphics 605 on Proxmox Privileged LXC - Fate - 2024-08-25

My mounts look a bit different in lxc conf:
Code:
lxc.cgroup2.devices.allow: c 226:0 rwm
lxc.cgroup2.devices.allow: c 226:128 rwm
lxc.cgroup2.devices.allow: c 29:0 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.mount.entry: /dev/dri/renderD128 dev/dri/renderD128 none bind,optional,create=file

Was your container always privileged? I think if you have changed from unprivileged to privileged you have to reset the user/group ids. (probably easier to reinstall the container)

I would recommend tteck scripts to create your container if you are unsure.

Which intel drivers did you install on the proxmox and on the lxc side?

Thanks for the reply

Yeah, I'm pretty sure I did at least. I added the following lines to my LXC.conf:

Code:
lxc.cgroup2.devices.allow: c 226:0 rwm
lxc.cgroup2.devices.allow: c 226:128 rwm
lxc.hook.pre-start: sh -c "chown 0:104 /dev/dri/renderD128"

which contains variables (226:0, 226:128 ) based on the output of "ls -la /dev/dri" run on the proxmox host
Code:
total 0
drwxr-xr-x  3 root root        100 Aug 25 04:32 .
drwxr-xr-x 20 root root      4780 Aug 25 04:50 ..
drwxr-xr-x  2 root root        80 Aug 25 04:32 by-path
crw-rw----  1 root video  226,  0 Aug 25 04:32 card0
crw-rw----  1 root render 226, 128 Aug 25 04:32 renderD128

I've tried changing the 104 in "chown 0:104 /dev/dri/renderD128" to 106 as well, to cover the render getent group in both Proxmox host as well as LXC guest.

On my proxmox:

crw-rw---- 1 root video  226,  0 Jun  5 00:03 card0
crw-rw---- 1 root render 226, 128 Jun  5 00:03 renderD128

on my lxc:
Code:
[root@kuroko dri]# ls -lh

Looking at your log earlier it seems to mismatch your proxmox side, so I'm pretty sure this is your issue.

Could you spawn a test container with tteck scrit and compare how the script mounts your devices?

Just to make sure can oyu post
dmesg | grep i915 on proxmox side?

Which intel drivers did you install on the proxmox and on the lxc side?

- My container was always privileged

- I think the drivers might have been the issue.

On Proxmox host I could see:
Code:
i965-va-driver-shaders/stable,now 2.4.1-1 amd64 [installed]
intel-media-va-driver-non-free/stable,now 23.1.1+ds1-1 amd64 [installed]

On the LXC guest I could see:
Code:
i965-va-driver/stable,now 2.4.1+dfsg1-1 amd64 [installed,automatic]
intel-media-va-driver/stable,now 23.1.1+dfsg1-1 amd64 [installed,automatic]

On the LXC guest I then ran:
Code:
apt install software-properties-common -y
add-apt-repository -y non-free
apt install intel-media-va-driver-non-free -y

and on the proxmox host, updated my LXC.conf with the value from "getent group render | cut -d":" -f3" as run on the LXC guest
Code:
lxc.hook.pre-start: sh -c "chown 0:{LXC getent output} /dev/dri/renderD128"

then rebooted the LXC.

After this I forced a transcode and for the first time saw activity in "intel_gpu_top" as run on the Proxmox host

I'm cautiously optimistic that this has resolved the issue. Thank you for your input.

Awesome! Glad I could help!
