Yeah I would say so. You still having issues?

Did you go here and look at the supported codecs for encoding and decoding?

https://www.intel.com/content/www/us/en/docs/onevpl/developer-reference-media-intel-hardware/1-1/overview.html#ENCODE-OVERVIEW-11-12

Ah OK what GPU are you using? are you using the integrated graphics of your CPU?

This is most likely because of encoding. Did you change any settings in jellyfin for hardware acceleration? Have you passed theough your GPU? You will need to find out what codecs your GPU supports and enable those in the jellyfin hardware encoding spot.

I run jellyfin on an LXC, so first get jellyfin installed personally I would separate jellyfin and your other docker containers, I have a separate VM for my podman containers. I need jellyfin up 100% of the time so that’s why its separate.

Work on the first problem, getting jellydin installed I wouldn’t use docker, just follow the steps for installing it on Ubuntu directly.

Second, to get the unprivileged lxc to work with your nas share follow this forum post: https://forum.proxmox.com/threads/tutorial-unprivileged-lxcs-mount-cifs-shares.101795/

Thirdly, read through the jellyfin docs for hardware acceleration. Its always best practice to not just run scripts blindly on your machine.

Lastly take a break if you can’t figure it out, when I’m stuck I always need to take a day and just think stuff over and I usually figure out why its not working by just doing that.

If you need any help let me know!

^^have you tried this? I needed to enable for my banking app to work.
