Multiple Camera Stream for android/ios app

Hi, i don’t know if this was ask here.
I have a client who wanted to have an application for Tutoring machine which runs on android. I know you can add external camera for android using usb. When i search about Multiple camera support for jitsi there are few queries. https://www.reddit.com/r/jitsi/comments/i371gm/multi_camera_support_in_jitsi_meetings/

My question is, can you send 2 stream of cam where the other one is the students cam(face) and the other is students table. The idea is the other camera will capture if the student really is the one answering the offline test paper.

is there any specific example where i can send stream. The example is really just joining the room.

You would need to use OBS virtual camera which is currently on Linux and windows. Half of the camera output would show the students paper and the other half the face
