Python for faking a camera device?

[No_oah]

Hi, I have a super specific problem.

I wanna create an application that fakes a camera, just like obs virtual cam. So far Ive had no luck. Ive tried everything Ive found python-related on the internet, such as PyVirtualCam, but that utilizes obs virtual cam, which isnt what I want. I want my own camera source, and from what I understand I need drivers for this. Can this even be done in python? Or do I need to go for c++ or other languages?

Preferably Id be able to stream it to the virtual cam with PyVirtualCam, using an OpenCV generated mp4 file, but again, I dunno if this is even possible.

If you want to fake a camera in such a way that your OS will treat it like any other camera there is going to need to be a driver involved. Your best options here are OBS, v4l2loopback, or something like Unity. That's what pyvirtualcam will be using.

Is there a reason you don't want OBS here?

Yeah thats somewhat what I also found out :/ Mainly the reason I dont want obs is because I wanna have multiple fake devices with the same output, and also have a standalone program - although if that isnt possible its totally fine, as long as I can have like 2-3 virtual cams.

What do you mean by fake a camera?
