I want a streaming server that can simulate TV-like channels. I want to schedule different channels with my own content that I've downloaded. Shows and movies will be on at different times of day regardless of whether I'm watching or not. And then on my TV I could browse these channels with a guide. Tune into a show already in progress, and all that. But I set up all the schedules.
Also looking for this with the additional conditions:
It's standalone, so it doesn't need integration with Kodi/Plex/Emby/Jellyfin/Whatever.
It has its own front end that I can point friends and family towards.
It has docker support so I can run it containerized.
It doesn't require me to sign up for a monthly subscription for the privelege of running it on my own server.
