I've been running my Jellyfin server for a while now and for the most part things are going great! However, sometimes when streaming, the server will stutter or just stop to buffer for quite a while. I *supposedly* have hardware acceleration working, but I'm not 100% sure it is. So a few questions:
I'm suspicious that hardware acceleration isn't working because of (1) the buffering and (2) when I check my GPU's usage with intel_gpu_top, I see this:
All of the usage remains at 0.00%, even when streaming.
Details:
Jellyfin versions (obtained through the AUR):
OS Versions (I'm running Manjaro):
Hardware Acceleration Configuration:
(screenshot attached)
Outputs of the commands given in the hardware acceleration documentation:
(looks normal to me)
/usr/lib/jellyfin-ffmpeg/vainfo doesn't exist (even though /usr/lib/jellyfin-ffmpeg/does), but I can run regular vainfo:
which implies that the H264 codec *should* be supported.
And I have the items listed as required in the docs:
An example file that buffers
Running ffprobe on a file that buffered gave the following:
So the encoding looks like it's just normal h264.

- If hardware acceleration is working, will Jellyfin lower the resolution of the stream instead of buffering?
- In either case, how do I verify that hardware acceleration is actually happening?
