3% is there anything i can do to make it use more like 100%??
if u need more info let me know

Did you install all the Intel drivers, including the opencl and media drivers?
What is the output of
Code:
sudo vainfo --display drm --device /dev/dri/renderD128RE: intel low gpu usage when transcoding - SuperficialNight - 2023-12-09

I'm having trouble finding something I found for my setup. Something about the clock speed never ramping up beyond the lowest power state, which is possibly your problem as well. Search around for that?

don't think its that i did a h265 transcode with normal ffmpeg and i get this
https://ibb.co/QHrXw4c
so the gpu can go to 100%
is it possible it is something wrong with jellyfin-ffmpeg?
do i need to specify to use jellyfin-ffmpeg in the configs?
RE: intel low gpu usage when transcoding - TheDreadPirate - 2023-12-09
It shouldn't matter. You don't HAVE to use jellyfin-ffmpeg. In Dashboard > Playback you can specify a different ffmpeg.

that did it choosing jellyfin-ffmpeg i now get 148 - 256 fps
thank you very much off topic how is using ramdisk for transcoding?
RE: intel low gpu usage when transcoding - TheDreadPirate - 2023-12-09
The only reason I use a ram disk is that I have an old ass SSD with good read speeds but not good write speeds. And my Arc A380 can transcode faster than it can write.
It is definitely not recommended since people tend to underestimate how much space they need. I did a lot of testing and experimentation to determine that 24GB was enough for my transcode ram disk. As soon as I get a new SSD I am getting rid of the ram disk and will just write to the SSD.
Could you share your ffmpeg log? When you were using jellyfin-ffmpeg. I'm curious if there is anything in the log that would point us in the right direction. I might have you open a bug report for jellyfin-ffmpeg.
