I believe, Icecast ticks at least some of your criteria. It’s been around since forever, so it’s probably the most stable option and even a Pi1 is likely overkill for it. No idea how it holds up in terms of UI, app and Docker, though.
They do have a mirror on GitHub, but the main repo is on a self-hosted GitLab.















I’m towards the hyperphantasic side of the spectrum and I’ve also noticed that it influences quite a lot of things.
Perhaps the biggest factor is that I don’t have the same drive to visit places or people. I could travel to a castle to look at it, or I could do so in my mind. I could meet back up with an old friend, but as I think of them, my desire to see them again is satiated. This does mean I’m terrible at maintaining friendships and socializing in general.
