Added Arc A380 for transcoding: Failed to get number of OpenCL platforms: -1001.

Followed the guide as best I could, no errors, until I got to this command:

Code:

Is any of that anything I need to try to correct?  It does seem to be working, CPU usage did not hit 100% and the transcode log said it was using QSV.  Hit almost 500fps transcoding for the playback in Mozilla, before on the same file it was just under 60fps.  I don't have BAR support, it's 4th Gen i5. Lastest jellyfin 10.11.3 of course.  Ubuntu baremetal 24.04; tried adding  NEOReadDebugKeys=1 OverrideGpuAddressSpace=48 to the environment like I found in an old github forum post for the intel compute-runtime.  Didn't seem to make a difference.

Thanks for looking.

I'm using the ARC A310, basically the same. Here's what your command looks like on my system.
I have the iGPU in bios turned off and I also don't have resizable BAR. (not a requirement)

Check the version of intel-opencl-icd thats the Linux distro provides:

$ apt policy intel-opencl-icd

intel-opencl-icd:
  Installed: (none)
  Candidate: 22.14.22890-1
