How can I detect whether the actual HTML5 player is being used, or if a 3rd party player is hi-jacking the video outside of HTML5?
iPhone doesn't use the HTML5 video player (thanks Apple) but rather uses its own player full-screen. This means any apps, regardless of responsive design, don't work if they expect an interface to be involved with the video.
So I need to know this in order to either make my app work differently with devices that do something similar to iPhone, or at least fail gracefully.
