[Guide] Jellyfin + remote network shares + HW transcoding with Intel's QSV + unprivileged LXC

You're right. I made a mistake - I tested it out last weekend and had the same result as you with NFS. I am almost certain I lost data this way but it seems less plausible now. Perhaps it was for local bind mounts? I should really test again with local bind mounts to confirm. Sorry for the misinformation.

No problem, and thank you for the clarification. I can't say what went wrong on your end. I was just surprised that the mount point wasn't deleted during my tests. Thank you again for the clarification.
 
I am hoping someone can help me figure out why transcoding isn’t working for me.

I followed this comment

I have just set-up Jellyfin on my N100 machine with Proxmox 8.2 and I found that setting up GPU passthrough is much simpler.

There is no need editing the config or user groups. All thats needed is to go to container's Resources tab in the web UI and add a Device Passthrough.
There, put the /dev/dri/renderD128 and fill in the GID of render group. Jellyfin adds its user account to render group automatically during installation, so it should work out of the box.

I had an issue with the passthrough not working initially, but it was due to GPU driver mismatch. I updated both host & container with the latest driver from https://github.com/intel/compute-runtime/releases and then it worked perfectly.

So basically all thats needed:
1) Setup passthrough as mentioned above
2) Mount NFS share (using mount point so container can stay unprivileged)
2) Install jellyfin
3) Potentially update the GPU drivers, if running
Code: 
/usr/lib/jellyfin-ffmpeg/ffmpeg -v verbose -init_hw_device vaapi=va:/dev/dri/renderD128 -init_hw_device qsv=hw
gives errors in red about init failing.

And the output of command 3 shows no errors. I made sure that the GID in CT is the same as the render group on my host using
getent group render which showed me 103.

I am using a 10th generation intel processor and proxmox 8.3.2

The initial instructions don’t say anything about installed opencl on the host so I haven’t done so. I’m also not sure which one would need to be installed because I don’t see mention of the 10th generation in the GitHub repo.

I do have intel-media-va-driver:amd64 23.1.1+dfsg1-1 on the host.

The ffmpeg logs don’t really tell me much

You have to Put "/dev/dri/renderD128" under QSV Device in jellyfin settings. In your Screenshot it's empty.
 
Thanks for the suggestion. I did get a different error

After more debugging, I realized that the render device in my container was owned by the KVM group.

I’m not sure if this is related to me, passing through the device on the GUI, but ultimately, I added the jellyfish user to the KVM group, and this allowed transcoding to work, so my issue is resolved
