Protip: if your goal is to use your smartphone as a webcam, check out this:
https://vdo.ninjaWritten by some guy named Steve, it’s an incredible piece of web software that uses WebRTC to stream phone audio and video as an OBS input. OBS then features a virtual webcam capability to take that stream and make it a webcam. I can then also use OBS to do whatever processing I want, e.g. making my webcam also contain a screen share or whatever else.
It’s trivial to then load up multiple instances for multi-angle scenes in OBS, then cut between the two. For example, you could have one ‘face’ camera and one ‘page’ camera showing paper on your desk and make a 2nd scene with the ‘page’ camera as the primary and a small PIP view of your face.
It goes much farther than just being an input for OBS, though. For example, it can create video chatrooms of multiple participants with URL parameter configuration and without touching OBS (indeed that’s now one of its primary use cases).
I use it to stream applications/webpages with my partner when we’re apart so we can watch a movie together by creating a high res vid/stereo audio input with no noise cancelling as the movie, then have her and I connect as lower quality, mono+noise cancelling participants. Each of us receives the video and audio of the movie, but only the audio of each other.
There’s heaps of parameters to control video and audio quality, buffering, etc. - just about anything you need.
I stumbled across it when I was trying to get my iPhone to be a webcam early on in the pandemic. There’s multiple apps for that purpose - many paid - but this was so easy and worked so well that it blew them out of the water from a capability perspective.
I know I sound like a shill but honestly I’m just a huge fanboy. It’s one of those web apps that does a job really bloody well, with heaps of flexibility and extensibility. I’m genuinely impressed with it and all the hard work Steve’s clearly put in.
The docs explain a lot of its capability: https://docs.vdo.ninja/
Flick through the how it works and use cases pages, they’ll explain it far better than me.
