Screensharing content detection
One interesting feature in WebRTC is the ability to configure a content hint for the media tracks so that WebRTC can optimize the transmission for that specific type of content. That way if the content hint is "text" it will try to optimize the transmission for readability and if the content hint is "motion" it will try to optimize the transmission for fluidity even if that means reducing the resolution or the definition of the video. This is specially useful when sharing documents or slides where the "crispiness" of the text is very important for the user experience. You can see the impact of those hints in the video encoding in this screenshot taken from the W3C spec: This is very useful but there is a small problem. What happens when we don't know the type of content being shared? How do we know if the browser tab being shared has some static text slides or a youtube video being played? One possible option could be to do some type of image pro
