Good question. I’ve also been looking for some good open-source solution to live stream the camera. Using some proper standard ao I can easily use it. Seems most webcam live streaming apps either include proprietary parts, or are unmaintained for several years now. I usually look at what’s available in the F-Droid store. But seems we’re out of luck. There is “Remote Video Camera” which can transfer video between two phones. But that’s pretty much it. If you want to integrate it into other software, search on Github or Google and maybe include in the search query, the protocol or software you want to connect it to.
