rockchip transcode - missing /dev/mali0 - Sean (MentalUproar) - 2025-01-28
I'm having trouble on setting up Jellyfin in Docker on an Ubuntu Ambian install on my orangepi 5 plus. I'm running the 6.1.84-vendor-rk35xx kernel. All the other HW transcode devices are present, but /dev/mali0 is missing, so I can't pass it to the docker container.
clinfo shows the following

Segmentation faultRE: rockchip transcode - missing /dev/mali0 - gnattu - 2025-01-28
it seems like you are using the panthor kernel driver instead of mali. You need to add a dt-overlay to prevent panthor being loaded.

Thank you, that was the problem!
