Playback Failed Due to a Fatal Player Error with Intel QSV on Jellyfin

[Jelly_]

Hi everyone,

I recently tried updating my Jellyfin server, but it stopped working due to some issues. I decided to do a fresh install and followed this guide to set it up on my Proxmox server.

Server Specs:
Processor: i7-12700H
Memory: 64 GB RAM
Storage: 1 TB SSD

Jellyfin LXC Container Specs:
Cores: 4
Memory: 8 GB RAM
Disk Space: 30 GB

The issue I'm facing is that whenever I try to enable Intel QSV for hardware acceleration, I get the error: "Playback failed due to a fatal player error." If I disable hardware acceleration, the videos play, but the CPU usage spikes to almost 95%.

I've attached the log file for reference.

Does anyone have any advice or troubleshooting tips on how to resolve this? Has anyone else experienced this issue?

Thanks in advance for your help!
