Playback Error

[Cryotan]

So i've been trying to get my Jellyfin working on my PC.

Relevant Hardware/Software information:
Method: Installed Jellyfin directly from Terminal
OS: Debian 12
CPU: i5-2500
RAM: 16GB

Everything seems to be set up correctly until I try to play a video, it gives me the following error: ''Playback failed due to a fatal player error.''
I used Video Acceleration API (VAAPI) for this, I've tried various other hardware accelerators but when playing the video it keeps giving me the same error.
However, I found out that the video will play if I disable the hardware accelerator. It's not recommended because my videos will be too slow it's not enjoyable.

Here is what I also tried doing:
Installing the Intel VA-API Driver
Making sure there is access to the videofile

I would like to provide logs but whenever I try to upload it's telling me to use a different type, t's a plain text document.
Let me know if you need to know anything else i'll gladly provide it.
Thank you in advance for your help.

You have an intel i5-2500 that's codenamed "Sandy Bridge".
https://www.intel.com/content/www/us/en/...tions.html

Use this wiki table to figure out the codecs that your CPU's iGPU supports: https://en.wikipedia.org/wiki/Intel_Quic...d_encoding

So in your dashboard's playback settings for HWA, you should:

Enable these decode codecs:
1. H264
2. MPEG2
3. VC1

Disable these decode codecs:
1. HEVC
2. VP8
3. VP9
4. AV1
5. HEVC 10bit
6. VP9 10bit

Finally, you can enable encoding using HWA, but you cannot encode to HEVC or AV1 with the iGPU.

That seems to have solved the issue thank you so much! The videos play rather slow however I’m guessing it’s time for an hardware upgrade. I’m guessing if I were to use a CPU without integrated GPU paired with an Nvidia GPU I’m supposed to choose “nvenc” as accelerator right?

Correct. But if whatever you buy will only run Jellyfin, modern Intel CPUs have extremely capable iGPUs for transcoding. If you only have a couple users you don't need a dedicated GPU.

I am planning to use it just for Jellyfin, however i'm running it through a Reverse Proxy which requires SSL encryption so I definitely need some extra power.
Enabling and disabling codecs has worked but now Jellyfin stopped playing videos through my domainname. I'm really confused because last time I used Jellyfin the videos did play through my dommainname.
Maybe I changed a setting by accident, any idea what it could be or am I supposed nginx for help? Considering Jellyfin plays locally but stopped working threough proxy server.

I also really appreciate your time and effort.

Is this vanilla Nginx or Nginx Proxy Manager? Can you share your config file (censor the domain) if vanilla Nginx. Take screenshots if Nginx Proxy Manager.

It's Nginx Proxy Manager, what exactly do you want me to take screenshots of? There are many settings.

Go into the proxy settings for Jellyfin and take a screenshot of each tab (4 tabs IIRC). Censor the domain.
