yes, both OBS and, as a standalone, DroidCam do this, as android and PC apps. Does this just integrate these apps, or something like it?
Droidcam is the first app in my life I paid money for. I'm not happy with it. On Linux in particular, I have to reinstall it almost every time I update the system. Every so often it doesn't connect on first attempt- so I close it, restart and then it inexplicably starts working. I would probably forgive a more serious bug, but this is just annoying and silly.
I started with Droidcam during the pandemic and switched to Iriun. Currently using it with an old iPhone SE over USB, but also used with Huawei P20 Pro. Not many features, but just works.
I used iriun a lot, a problem that I have with it is how much my Samsung phone heats up when using a higher resolution. Probably a Samsung/Android problem more than Iriun. I would love to have a phone quality camera in a regular USB webcam.
But this doesn't let you use your phone's camera as a webcam on MacOS.
Might be for your device specifically. I don't have the UVC option in the USB settings.
