I occasionally have a reason to use idjc to send a stream to my remote server which is then, in turn, streamed to an opensim server (although it isn't exclusive - anyone with the address could tune in with vlc etc.). I do this from my desktop using idjc, jack and icecast, with a full GUI.
Anyone know how to do it from a PI in headless mode? That way, I could have the stream always on.
NB. I'm not bothered at this point about controlling the stream - I'll figure that out. It's just the initial setup I need. The way I do it now is with qjackctrl using the net driver pointing to my VPS. Headless - I've never done.
