SOLVED: Low Transcoding Performance with Intel i3 6006U and HD520 GPU

[Artik1]

Hi everyone,
I've recently set up Jellyfin on my system, running Debian with Docker. My setup includes:

• CPU: Intel i3 6006U (3 "cpus" for the vm)
  
• GPU: Intel HD520
  
• RAM: 8GB (6GB assigned to the VM)
  

When transcoding, I only get around 15fps. I checked the performance using
intel_gpu_top and noticed that the GPU usage is low, while  htop shows the CPU running at full capacity.
Any suggestions on how I can improve transcoding performance, especially utilizing the GPU more efficiently?
Thanks in advance!
