It seems to have been a problem either with the specific package ubuntu was installing or some dependency. I went to the Intel compute runtime github and installed the latest packages from there after purging the ubuntu version.
Transcoding with ffmpeg now works correctly and clinfo no longer crashes.
Ubuntu was installing version 23.43.27642.40-1ubuntu3 and the latest intel release is 24.35.30872.22.
Link for reference if anyone else comes across this issue: https://github.com/intel/compute-runtime/releases
This was run after I'd installed the intel packages, so not really needed but I'll put it for reference anyway:
Thanks for your help.
