Playback Error - Client isn't compatible

[TheDreadPirate]

Hello all

I have the latest jellyfin server installed as an addon in truenas core which is itself installed as a vm on proxmox 8. Not on docker

I have the same issue as above and i tried all the recommendations to no avail.

From server "This client isn't compatible with the media and the server isn't sending a compatible media format".

Fron jellyfin media player "Playback failed with error "loading failed". Retry with transcode? (Note this may hang the player."

I have this issue regardless if i try to play any media from the server directly or from a jellyfin media player. Transcode is set to auto.

What can i change to make work

Thank you in advance for your help

Jellyfin is probably trying to transcode and failing.  With virtualization you have to pass the GPU through each layer.
