It’s not the same as having two mirrors, the camera-screen setup doesn’t involve the same physics. In the camera-screen setup, the only optical phenomena taking place is the absorption of photons by the camera’s sensor. Once the image is formed in the camera, all other effects are electronic, digital or electromagnetic in nature. The representation of the ...

This was commonly used by students to make artsy videos to music that were played on U.S. PBS TV stations. If the camera and the screen are not perfectly aligned, each frame in the regression is rotated relative to the previous frame. This gives a spiral effect and simply twisting the camera to the rhythm of the music caused the spiral rate to change. ...

It is quite similar - but there is a delay. The camera "sees" a frame, then processes it, and displays it. It is like the dual mirrors, but while the dual mirror setup "instantaneously" shows an infinite array of mirrors-in-mirrors, there is a delay (typically 1/30 of a second) for the camera from frame to frame, so the frame-in-frame happens more slowly. ...
