I remember reading a post about someone setting up Jellyfin and some other software and essentially just waiting around a few days after shows come out and they end up being available in their media library. Like, some kind of pirating software that just grabs the right media. Is this a thing or am I misremembering?
Sounds like they are using the “*Arr” software.
The WikiArr had a good break down of how it works
They are designed to automatically grab, sort, organize, and monitor your Music, Movie, E-Book, or TV Show collections for Lidarr, Radarr, Readarr, Sonarr, and Whisparr; and to manage your indexers and keep them in sync with the aforementioned apps for Prowlarr.
This sounds like Sonarr. I haven’t used it but I’ve seen people talk about it. It watches RSS feeds for releases and tries to find the best torrent.
Yea that’s basically sonarr with a downloader like transmission. Which are separate from jellyfin. Go here to learn for to set it all up. servarr
