RE: Transcoding - DenaliX - 2024-11-18
Yes. Its a Proxmox LXC.
RE: Transcoding - TheDreadPirate - 2024-11-19
That is very important information, btw. Should have been in the opening. Because that is an additional layer of virtualization you have to deal with. Did you pass the GPU into the LXC? And is the LXC privileged?
RE: Transcoding - DenaliX - 2024-11-19
Sorry about that. Once I got the renderD128 to show up in /dev/dri I figured the rest was straightforward. I added the following to the LXC .conf file...
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/dri dev/dri none bind,optional,create=dir
lxc.mount.entry: /dev/dri/renderD128 dev/renderD128 none bind,optional,create=file
It is an unprivileged container.

You also did step 2 of our guide?

Quote:Proxmox VE 8 or Newer:
Setup a Device Passthrough for the render device via the Resources section of the web interface. Be sure to set the correct GID via the advanced options of the dialog, e.g. 989 for the render group. GIDs can be looked up in /etc/group inside the LXC.
RE: Transcoding - DenaliX - 2024-11-19
When I add /dev/dri/renderD128 with Device Passthrough (render group 104) the container won't start anymore. The error is...
run_buffer: 571 Script exited with status 17
lxc_setup: 3948 Failed to run autodev hooks
do_start: 1273 Failed to setup container "104"
sync_wait: 34 An error occurred in another process (expected sequence number 4)
__lxc_start: 2114 Failed to spawn container "104"
TASK ERROR: startup for container '104' failed
RE: Transcoding - TheDreadPirate - 2024-11-19
I am not familiar with Proxmox so I'm not entirely sure how to troubleshoot that. Make sure that the render group ID is the same on your proxmox host as it is inside the LXC. 104 may be what is used in the LXC, but not in Proxmox.
RE: Transcoding - DenaliX - 2024-11-19
OK. I took the info out of the lxc.conf file and added the card0 and the renderD128 to the passthrough and got the container to load and the card0 & renderD128 are present in the container /dev/dri.
When I run /usr/lib/jellyfin-ffmpeg/vainfo --display drm --device /dev/dri/renderD128 in the Portainer Console I get this...

RE: Transcoding - TheDreadPirate - 2024-11-19
In Dashboard > Playback > Transcoding. What do you have set for the "QSV Device"? Usually it is blank, and this is usually fine. But try putting /dev/dri/renderD128 in that field.
RE: Transcoding - DenaliX - 2024-11-19
I don't have a QSV Device in that menu. If I change to VAAPI I get a VAAPI device. In the VAAPI menu the renderD128 is listed...
RE: Transcoding - TheDreadPirate - 2024-11-19
Ah. Even though you are on the "latest" tag, it probably isn't on 10.10.3 based on the version of jellyfin-ffmpeg.
Can you switch your LXC to be privileged?
