So I made a quick guide on using Jellyfin on Rockchip SBCs not so long ago. The guide is outdated - Jellyfin has RKMPP support since 10.9 version:

This tutorial guides you on setting up full video hardware acceleration on Rockchip VPU via RKMPP.

Don't forget to passthrough the video devices and check if they works fine.

My docker-compose file looks like this:
