Transcode doesn't work on web

[monointent]

Hello all, I seek help
I am running an Arc gpu through a kube cluster.
When viewing certain titles through the web GUI, it will prompt for a transcode issue or just spin indefinitely.
When viewing the same media on the same machine but using the app from the GitHub, it plays just fine and I can adjust the playback settings.
I am not sure if there is a miss-config somewhere.
I have attached the logs, any help would be greatly appreciated.

What kernel is your system running?

What kernel is your system running?

running uname -r

on the proxmox host
$ root@mainframe:~# uname -r
$ 6.5.11-8-pve

on the Kube Cluster node
$ mono@sous3:~$ uname -r
$ 6.8.0-38-generic

I'm assuming the "kube cluster" is running Ubuntu 24.04. Kernel 6.8.0-38 inherited an upstream kernel driver regression that breaks transcoding. Roll back to 6.8.0-36. There is a ticket in with Ubuntu's kernel team to backport a pair of patches to resolve the issue.

For now stick with 6.8.0-36.
