title: <video> responsive resolution both for mobile and desktop browser
body: <p>I have a simple question about the <code>&lt;video&gt;</code> tag.</p>
  
  <p>I want to build a simple full screen video chat that runs on <code>PhoneGap</code> (mobile) and desktop browsers (<code>Chrome</code>).</p>
  
  <p>What I need is the video to stay full screen both if it comes from a mobile camera or desktop browser camera. I guess they will have different aspect ratio and I don't understand how to merge the problem.</p>
  
  <p>What I am afraid of is, when video comes from a mobile camera then how could it fit the entire browser screen (full screen) which is bigger?</p>
  
  <p>I am sorry if I haven't tried anything yet, but I just would like to understand what to start with, the logic behind.</p>
  
  <p>Any tip appreciated!</p>
