title: WebRTC resolution limit
body: <p>I tried <a href="https://stackoverflow.com/questions/15391309/how-to-control-camera-resolution-for-webrtc-in-chrome">this</a> and <a href="http://simpl.info/getusermedia/constraints/index.html" rel="nofollow noreferrer">this</a>, but the maximum resolution I can get is 640x480.<br>
  The pictures taken by other windows apps by the same camera have the resolution of 1600x1200.<br>
  Is there any limit for resolution in WebRTC?<br>
  I cannot find any official documentation about that.</p>
