How to control camera resolution for webrtc in chrome?

webrtc

Solution

You can include a request for a specific resolution in the constraints object passed to getUserMedia. For example:

window.navigator.webkitGetUserMedia({
  audio: true,
  video: {optional:[ {minHeight:720}, {minWidth:960} ]}
}, onSuccess, onError);

Problem

We are using webrtc in chrome to do video conferencing. That works but it uses our webcam with a bad resolution and in 4:3 aspect ratio. The cam however can deliver HD video in 16:9 format. How can I control this? By changing Windows settings, chrome configuration or html code?
