This module allows you to create “virtual video devices”. Normal (v4l2) applications will read these devices as if they were ordinary video devices, but the video will not be read from e.g. a capture card but instead it is generated by another application.
Then you cannot access it, same as how you can’t sign up to OF as a creator or any online govt services. Most of those don’t even let you use a PC, only a phone, via an app that checks your phone for root, same as banking apps. Were you born yesterday?
What’s preventing you from uploading a random photo for that estimate age from selfie button?
You can’t upload, only use the camera
Nobody has created some sort of fake virtual camera thing? Like it appears in device manager as a real webcam, but the output is altered?
I’d assume that this is something that can be most-easily bypassed at the browser level if a site can request access to a camera.
I don’t think that any trusted-to-the-camera hardware stack exists today.
But at an OS level…
I dunno about Windows, but Linux can do virtual video-4-linux devices, which is probably how the OS exposes a camera to a browser on Linux.

Yes of course they have like sparkocam or manycam and of course the mentioned below v4l devices on linux
What if your PC has no camera?
Then you cannot access it, same as how you can’t sign up to OF as a creator or any online govt services. Most of those don’t even let you use a PC, only a phone, via an app that checks your phone for root, same as banking apps. Were you born yesterday?
Hold up a photo of any random schmoe?
Have you never done one of these for an ID check? Doesn’t work like that, it will likely ask you to turn your head so it can take a “3D” scan.
