On a Me Mini N200 I installed Jellyfin app v10.11.4 on Truenas 25.04.2.6. I setup hardware acceleration in Jellyfin with Intel QSV method and it seems working, but in a weird way.
Without hardware acceleration the CPU load is 50%, but if I set it I see the load increase to 54 or sometime more.
On some video intel_gpu_top shows the GPU working for Render/3D, Video and VideoEnhance, on other videos shows nothing, the CPU load does not seems to have any change when GPU is or isn’t working.
At least in one video I’ve seen the GPU all at 0% and the CPU at maximum 1% (?!?).
Jellyfin documentation for hardware acceleration warns that: “Some of these stages cannot be GPU accelerated due to software, hardware or driver limitations. Partial acceleration may result in higher CPU usage and lower transcoding speed.”
I wonder if the problems I’m facing can be solved or not, and how to debug them.
