I experimented with Plex-htpc and I think it is already quite useable on Linux and basically replaces Plex Media Player. At least I did not miss any feature. If Plex is committed to further developing it into a stable release, and if this brings official Linux support, I think I can be happy again with Plex.
There were however some hurdles.
- install it with the install script.
Plex HTPC feedback
It seems to not only install the application, but it also establishes some connections to system services. - On a wayland system you need to start it without wayland. The following command line works for me:
DISABLE_WAYLAND=1 snap run plex-htpc
I think this makes the application use XWayland plugin and basically runs it with X.
I did put this into a start script and created a .desktop file for integration in the laucher/Dock.
This works and in my opinion I have a suitable replacement now for Plex Media Player.
