Playback issue but transcoding works

[Peronia]

Sure, here they are:
Jellyfinlog
Transcodinglog

Is Debian installed bare metal on a system? Or is it a VM?

[Peronia]

It's a lxc container which runs at Proxmox (Jellyfin runs always inside a container in my network).

[TheDreadPirate]

So Proxmox > Debian > Jellyfin installed directly on Debian?

What is the storage for this LXC? A local disk? Network storage?

[Peronia]

Yes you're right. The storage is a local disk and the movies are stored at a nfs share.

This shouldn't matter, but why aren't you using hardware acceleration? What are your hardware specs?

I turned on debug logging on my test setup to see what a normal transcode debug log looks like. I have this line in mine that I don't see in yours.

Code:

[2024-02-24 17:58:39.022 +00:00] [DBG] [16] Jellyfin.Api.Controllers.DynamicHlsController: Finished serving "/config/transcodes/c545c75f9b6db8892b4f63f9ea2121e51.ts"

"Finished serving" logs never appear in yours.

Do you have anything going on in your network that could potentially block or alter network traffic? A pihole? Something like that?

[Peronia]

I have a Ryzen 5 1600 processor. This one has no graphic processors so I think I can't use hardware acceleration.
Yes I have a pihole. But I don't get it why this should interference Jellyfin. I have both for a long time...

[TheDreadPirate]

In a browser can you open the dev console and monitor it during a transcode?

[Peronia]

Yeah I already did it, so I found the hls error. See a couple of posts before.

[TheDreadPirate]

Right. Forgot about that. 90% certain you have some weird network issue going on.
