I have been trying to figure out the best way to access my local plex server from within Batocera. Is there some way to add a launcher for a preconfigured web browser that has the plex IP as the home page? I know there is Kodi on the system, i am just attempting to utilize something i already have running on the network and save a roku.
I have absolutely no idea about any of this stuff but have you tried seeing if you can connect to in via Jellyfin instead? https://flathub.org/apps/details/com.github.iwalton3.jellyfin-media-player
Maybe plex addon for kodi is an alterntive?
Never using kodi before i did not know there was an addon for plex. That might be the way to go. Thanks for the idea.
To address your original thought, you can install Firefox via Flatpak and even add it to your systems list. Then it would just be a matter of setting Plex as your start page.
Did you have success with the Plex add-on for Kodi?
