Flatpak permissions

[niels0n]

Do I have to grant the permission to read all my system files to flatpak?

I ask this because when I set it to "mpv_ext": true, then jellyfin-mpv-shim fails to start with this errors:

From FileNotFoundError: [Errno 2] No such file or directory: 'mpv' I assume that this is a problem related to flatpak's isolation.
Am I wrong?
