I have a requirement where there is a page with a list of video stream and on click of one of the video streams, the video stream within a div tag needs to go full screen. On top of the full screen video stream, I need to have a list of joystick controls like left arrow, right arrow, top , bottom etc. Can you pls help me understand how do I do it? I have started to create a new template for the fullscreen view but dont have enough clarity on how to go further.
