I use it every once in a while when I do a presentation in Teams at work and I need one webcam to show my mush, and another to demonstrate whatever device I’m presenting: I use the cellphone to capture close-ups of the device and focus on features people ask me to show, scrcpy sends the camera capture to a v4l2 device, and Teams uses the v4l2 device as a regular video source.
If you’re in Linux and you want the same thing right now, scrcpy already offers to expose your cellphone’s camera as a video4linux device. See here:

Super useful!
Not really an open-source approach, but I found that irium Webcam is generally a lot better if you’re just wanting to use your phone as one.
For some reason scrcpy just doesn’t work well for me.
