You are proposing we just ask the browser for a stream, it gives us whatever it wants, and then the app uses the setting API to figure out what the browser provided ?

So help me understand what the code would look like - could you give a rough sketch of what the code would be to get 4x3 aspect ratio and 15 fps.
