Pci passthrough for better Video performence

[vikozo]

Hello
on my PVE Server i have a VM with Jellyfin to watch Movies.
It works but the output is poor and not as good as hoped.
In a Forum i got a Information to add the Pci passthrough

but on the VM i got a
i select the device
ASPEED Technologie Graphics Family

and got the Error/Information
No IOMMU detected, please activate it.See Documentation for further information.

on the PVE Server
# inxi -G
Graphics: Device-1: ASPEED Graphics Family driver: ast v: kernel
Display: tty server: N/A driver: ast tty: 156x34
Message: Advanced graphics data unavailable in console for root.

have this Board
SUPERMICR R
X11SCM-LN8F/-F and X11SCL-LN4F

and this CPU
12 x Intel(R) Xeon(R) E-2246G CPU @ 3.60GHz (1 Socket)

Any Idea to get a better Video Output on the Jellyfin?

Have a nice day

It's an old thread, but should read : https://pve.proxmox.com/wiki/PCI(e)_Passthrough

Forget about the ASPEED! This is the BMC graphics, which only has very rudimentary graphics functions. No video-codec and/or 3D-acceleration. So, scratch that thought!
However, you might be lucky: Your CPU does actually have an integrated GPU.
See here: https://www.intel.de/content/www/de...cessor-12m-cache-3-60-ghz/specifications.html

Your two listed boards have no physical outputs, that the Intel iGPU could use, or respectively is connected to.
So, direct output over the iGPU is also a No-Go.
However, you could maybe talk to Supermicro, about enabling the iGPU in your BIOS anyway, in parallel to the Aspeed. So that it becomes available for decoding tasks in VMs and/or Containers, without direct output to a screen. Then you could set up a streaming server (plex or the likes) and finally connect to it's output for accelerated video output.

A lot of work for a pretty simple seeming task. You asked for it, though.
