How I got OBS “working”, maybe it will save you googling errors for hours like I did.
Using image in screenshot
go here and install all the packages https://forum.radxa.com/t/introduction-to-rockchip-multimedia-ppa-for-ubuntu-jammy/
sudo apt-get install xcb
then run this in the same terminal
and it should open.
I used this device for screen capture, thats as far as I have got.
Am trying to stream the Rock5 over the local network but run into this, baby steps I guess…
