Hey guys!
I am running a Jellyfin server with hardware transcoding on a Xeon 2176 which does a great job streaming to all of my clients.
My current issue is with my backup server which uses GPU passthrough on a VM to output video directly to a TV. This VM is only used to play Jellyfin but I am having a hard time getting it to work right.
I know that the HD 4600 of the i7 4765t is pretty weak but in theory it should work to play/decode most 1080p formats. This BU server is only running proxmox backup server and this player so the player is getting 90% of all the resources.
I am currently trying ubuntu and giving the VM 6 Cores (direct/host) and 12 GB RAM. My test file is a 50 GB movie in HVEC10 4k and the stream currently is running over Gbit LAN.
Even though CPU and RAM utilization is below 50% in direct-play AND transcode mode I keep getting small stutters.
In this ubuntu environment I already installed the latest VAAPI driver, tried firefox, chromium and the jellyfin player.
Since this machine is only intended for jellyfin I am free to install any operating system that promises the best playback experience.
What OS/player/settings could you guys recommend to get the best result when playing 4k blue-ray content in 1080p?
edit: oh and I forgot - the main issue might not even lie with the video stuff since I am getting audio issues even when video playback is fine. I already applied the recommended fixes for GPU/Audi passthrough which made things better but not fully fixed it. I feel it is worst when playing 5.1/7.1 content over stereo.
Oh wow, when I set ubuntu to 5.1 even though I only have stereo speakers (missing a lot of the audio) 90% of the playback issues in direct play and transcoding are gone... what might that be?!
Oh and btw. performance wise firefox is absolute king! Using the Jellyfin player my CPU cores max out in both modes.
