Edit: I think I’ve got it working now actually!
Well I just tried to get OBS + OBS Camera (iOS) set up to stream video with my phone, but have been completely unsuccessful. They are working fine separately but since I’m on such an old MBP (2009) and OS (10.11.6), I’m having a lot of trouble getting them to communicate. Gonna try a bit more in the next day or two but if I can’t get it working it looks like I’m gonna have to back out too.
