I've heard numerous times from folks that Owncast can't handle streaming and it's impossible. Well, it works. You don't need a million dollars to stream to your own server. The server transcodes only the qualities you select once, and then sends them your viewers. If you have 3 qualities and 300 people it doesn't have to process 300 separate streams, only 3. Bandwidth could become an issue, but Owncast has built in S3 bucket support and CDN support if required though I've never used it.

I've found a way to open streams with ffmpeg without having to display all of them, my machine crashed when trying to open 40 streams with MPV, so I will try that next and let's see how many streams I can open at once. Stay Tuned!
