I'm hoping to setup something my PT can use to remotely oversee my gym sessions. I was hoping to be able to stream 3x cams to him covering various angles/apparatus and he can choose remotely which one to fullscreen. Also need audio both ways and a single video feed from him. I'm hoping to make all this work under a small linux box - I have a spare rock64, or could order another RPi. I haven't yet installed OBS, is it likely it'll be part of my solution? Appreciate any thoughts or suggestions on other reading that might help with this project
