Fresh Proxmox install, having a dreadful time. Trying not to be dramatic, but this is much worse than I imagined. I'm trying to migrate services from my NAS (currently docker) to this machine.

How should Jellyfin be set up, lxc or vm? I don't have a preference, but I do plan on using several docker containers (assuming I can get this working within 28 days) in case that makes a difference. I tried WunderTech's setup guide which used an lxc for docker containers and a separate lxc of jellyfin. However that guide isn't working for me: curl doesn't work on my machine, most install scripts don't work, nano edits crash, and mounts are inconsistent.

My Synology NAS is mounted to the host, but making mount points to the lxc doesn't actually connect data. For example, if my NAS's media is in /data/media/movies or /data/media/shows and the host's SMB mount is /data/, choosing the lxc mount point /data/media should work, right?

Is there a way to enable iGPU to pass to an lxc or VM without editing a .conf in nano? When I tried to make suggested edits, the lxc freezes for over 30 minutes and seemingly nothing happens as the edits don't persist.

Any suggestions for resource allocation? I've been looking for guides or a formula to follow for what to provide an lxc or VM to no avail.

If you suggest command lines, please keep them simple as I have to manually type them in.

Here's the hardware: Intel i5-13500 64GB Crucial DR5-4800 ASRock B760M Pro RS 1TB WD SN850X NVMe

Ok lets start with that rendering - seeing those is good! You should only need to add some group access, so run this:

groups jellyfin

The output should just say "jellyfin" right now. Thats the user thats running the Jellyfin service. So lets go ahead and....

usermod -a -G video,render jellyfin
groups jellyfin

You should now see the jellyfin user as a member of jellyfin, video, and render. This gives access for the jellyfin user to make use of the gpu/hardware acceleration.

Now restart that jellyfin and try again!

Ok, consider it done! My concern is this section of the admin settings:

I followed Intel's decode/encode specs for my CPU, but there's no feedback on my selection. I'm still getting "Playback failed due to a fatal player error."

[–] curbstickle@anarchist.nexus 1 points 1 hour ago (1 children)

What do you have above that?

There should be a hardware acceleration dropdown, and then a device below that. Since you have /dev/dri/renderD128, that should be in the "device" field, and the Hardware Acceleration dropdown should be QSV or VAAPI (if one doesn't work, do the other)

[–] LazerDickMcCheese@sh.itjust.works 1 points 1 hour ago* (last edited 1 hour ago) (1 children)

QSV and '/dev/dri/renderD128'. I'll switch to VAAPI and see... Edit: no luck, same error

[–] curbstickle@anarchist.nexus 1 points 1 hour ago (1 children)

Just checked one of mine, VAAPI is where I'm set, with acceleration working. 7th or 8th gen or so on that box, so VAAPI should do the trick for you.

So should I be disabling some hardware decoding options then?

[–] curbstickle@anarchist.nexus 1 points 1 hour ago (1 children)

Might be a better question for someone who knows more JF ffmpeg configs, but I think the HEVC up top should be checked and the bottom range extended hevc should be unchecked. I think you should have AV1 support too.

Worst case, start with h264 and move down the list

[–] LazerDickMcCheese@sh.itjust.works 1 points 1 hour ago (1 children)

Great point actually, time for c/jellyfin I think. Would you mind helping me with the transferal of config and user data? Is "NFS mount NAS docker data to host" > "pass NFS to jelly LXC" > "copy data from NAS folder to LXC folder" the right idea?

[–] curbstickle@anarchist.nexus 2 points 55 minutes ago (1 children)

Also may be good for c/jellyfin, but what I'd see if you could do is leverage a backup tool. Export and download, then import, all from the web. I know there is a built in backup function, and I recall a few plugins as well that handled backups.

Seems to me that might be the most straightforward method - but again, probably better with a more jellyfin focused comm for that. I have moved that LXC around between a bunch of machines at this point, so snapshots and backups via proxmox backup server are all I need.

[–] LazerDickMcCheese@sh.itjust.works 2 points 18 minutes ago

Yeah, it seems like the transplanting of LXCs, VMs, and docker is fairly pain-free...where I really shot myself in the foot is starting on an underpowered NAS and network transfers are clearly not my friend.

I'm not familiar with the backup stuff, but I remember hearing about it being added recently. I'll look into it, thanks for the recommendation.

You taught me a lot of stuff in just a couple days. The overwhelming/anxious part of dealing with Proxmox for me is still the pass-through of data from outside devices. VMs aren't bad at all, but everything else seems like a roll of the dice to see if the machine will allow the connection or not
