jeffreyveon's answer will help reduce the chance that your user will choose deny, since she will only have to choose once.

In case she does click deny, you can provide a message that explains why you need the permission and how to update her choice. For example:

navigator.getUserMedia (
   // constraints
   {
      video: true,
      audio: true
   },

   // successCallback
   function(localMediaStream) {
      var video = document.querySelector('video');
      video.src = window.URL.createObjectURL(localMediaStream);
      video.onloadedmetadata = function(e) {
         // Do something with the video here.
      };
   },

   // errorCallback
   function(err) {
    if(err === PERMISSION_DENIED) {
      // Explain why you need permission and how to update the permission setting
    }
   }
);
