How to create a virtual webcam in Unity for VR application?

In my VR application, I have integrated a web browser. Now I want to do any video conferencing through that browser, be it ZOOM, Teams etc. For that I want the browser to detect one of Unity's camera gameobject as the webcam. Basically a virtual webcam instead of the real webcam. How can I do t$$anonymous$$s? I'm using Unity 2021.3

You need to create a RenderTexture. That is a Texture that is dynamically generated as opposed to static image. You then send the camera output to the texture. Next create a 3D plane and drag the RenderTexture onto the plane. Sort out angles and potentially clip planes and the camera output should then appear on the plane. You'll also need to remove the audio listener from the virtual camera because a scene can have only one audio listener.

But how is the Zoom (or Meet) going to detect this as an actual camera?

Not quite sure what you're asking now. You originally said "I want the browser to detect one of Unity's Camera Game object". You now want to use a real camera? You could try the WebCam Texture class but I think that only works with mobile. If you use

         WebCamDevice[] allDevices = WebCamTexture.devices;
         for (int i = 0; i < allDevices.Length; i++)
             print(allDevices[i].name);

you can get a list of devices that are usable. That might help identify if Unity can see you webcam or not.
