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!

Can you share your ffmpeg log? They are located in the same directory as the jellyfin log.

Also check out our Proxmox hardware acceleration documentation.

This looks like you haven't properly passed the GPU into the container.

What is the output of these commands when you run them in the container?

Code:

sudo /usr/lib/jellyfin-ffmpeg/vainfo --display drm --device /dev/dri/renderD128
sudo /usr/lib/jellyfin-ffmpeg/ffmpeg -v verbose -init_hw_device vaapi=va:/dev/dri/renderD128 -init_hw_device opencl@va

If the output indicates it can't access the GPU, read the guide I linked in my prior post.

Here the results of both the commands

sudo /usr/lib/jellyfin-ffmpeg/vainfo --display drm --device /dev/dri/renderD128

Result - https://pastebin.com/GevryrWW


sudo /usr/lib/jellyfin-ffmpeg/ffmpeg -v verbose -init_hw_device vaapi=vadev/dri/renderD128 -init_h

Is your LXC privileged? And did you read the doc I linked regarding proper GPU passthrough? It looks like your LXC has some level of access to the GPU since the two commands I had you run worked. So not entirely sure what is going on. But I also have never used Proxmox or LXC's with Jellyfin.

What codec is the video you are trying to transcode? I was having this problem trying to hardware transcode MPEG2 SD videos and VC-1 videos because my 12 series intel I5 didn't have the codecs to hardware transcode those.

I unchecked those and they started playing fine. Make sure all the codecs you have checked can actually be hardware transcoded by your CPU.

Unprivileged Container - No

I have already gone through the document Proxmox part and added those when I created the container.

Can you share screenshots of Dashboard > Playback? And the media info for the video you are having issues with.

Attached is the screenshot. I'm not able to play any kind of video.

I have added the screenshot of my playback settings. Let me know if you think I need to uncheck or add anything.
