This works with Jellyfin because it supports m3u:

Channels DVR also supports m3u:

The README mentions Plex and Emby, but those don't support m3u, so you need to use a proxy which makes an m3u source appear like a local tuner such as:

https://github.com/xteve-project/xTeVe

https://github.com/vorghahn/iptv4plex

Add Dispatcharr to the list!

There is also threadfin, which I found a bit more friendly than XTeVe.

Above system works pretty well but had trouble with encode/decode speed somewhere. Tried with N100 cpu and still had the same result...probably user error somewhere but none of the options seemed to work. No issues with UHF so kept using that.
