To get your RTMP stream into < OBS >, use the VLC (plugin) Source. As for reasons “why” - it opens up more streaming options such as NDI, and more stable connections to FB/YT/Twitch, et al. Adds virtually unlimited program options, as well as long-running and persistent streaming and recording - all while the Litchi stream feed comes and goes, through signal drop-outs and battery-changes.
For a Windows server solution, I’ve just discovered MonaTiny and added a < post > under livestream . It’s so simple, it barely needs a guide, except to keep from over-thinking it.
