I'm quite happy with the Docker version of Jellyfin on my NAS [1] setup. Snapraid [2] and mergerfs [3] join a bunch of hard drives into an highly available RAID with data corruption protection and backup-light functionality which is great for media libraries. Jellyfin scans the media library and exposes it over a web interface to browsers, media players or the Jellyfin Android app in the same network. If you follow a strict naming convention for media files, Jellyfin automatically gets metadata and subtitles from the internet.
