It's a sign of the times when someone misunderstands what "Live TV" means. lol
So I am literally streaming ATSC channels from my roof antenna with JellyFin. I didn't feel like paying a subscription fee (and anyways - no paid service has exactly the right XMLTV format JellyFin expects), so I wrote a scheduled task which scrapes the listings and ingests them with the REST API.
I didn’t misunderstand what you meant. I just meant you can “hack” the live TV feature of Jellyfin, and use it to create a “live” tv experience from local media.
You can use Ersatztv to create an automatically updated playlist, based on a Trakt or IMDB list. Back in the day, there was/is a a cool addon for Kodi called “PseudoLiveTV” and these apps replicate this functionality.
So you can have an always updated Christopher Nolan collection, Halloween movies, westerns, 24/7 90s cartoons, BBC nature documentaries or whatever.
You can pull any imaginable tv or movie list from Kometa using Ersatztv:
