I have a raspberry pi 4 connected to the TV that I want to use for a couple different apps (jellyfin client, YouTube, display foundry battle maps) and am looking for a launcher application that could switch between these. Ideally it could be controlled by HDMI CEC (or whatever it’s called). Does anyone have suggestions for this?
I gotta give LibreElec a 👍. If your tv can do HDMI control, then using the remote to control Kodi works by default.
Jellyfish plugin works incredibly easily too. YouTube, not so much.
I would like to put in something that I over heard about the pi5, it apparently can run Android tv. Which would solve all your requirements.
