JavaScript got 404 error while using getUserMedia() API error while using vernier caliper,error while using ghostscript,error

I have index.html and app.js - index.html

<!DOCTYPE html>
<html>
<head>
  <title>Realtime communication with WebRTC</title>
  <link rel="stylesheet" target='_blank' href="css/main.css" />
</head>
<body>
  <h1>Realtime communication with WebRTC</h1>
  <video autoplay></video>
  <script src="js/main.js"></script>
</body>
</html>

app.js =>

'use strict';
navigator.getUserMedia = navigator.getUserMedia ||
    navigator.webkitGetUserMedia || navigator.mozGetUserMedia;
var constraints = {
  audio: false,
  video: true
};
var video = document.querySelector('video');

function successCallback(stream) {
  window.stream = stream; // stream available to console
  if (window.URL) {
    video.src = window.URL.createObjectURL(stream);
  } else {
    video.src = stream;
  }
}
function errorCallback(error) {
  console.log('navigator.getUserMedia error: ', error);
}
navigator.getUserMedia(constraints, successCallback, errorCallback);

So when I open run index.html I got error - :8888/getUserMedia/[object%20MediaStream]:1 GET http://localhost:8888/getUserMedia/[object%20MediaStream] getUserMedia is not a function.

I also tried on apache server. But got same error.

Answer:1

include adapter.js and set video.srcObject = stream; Everything else is deprecated.

Answer:2
