我无法在 Google Chrome (v21) 中显示视频流
代码
<html>
<head>
<script>
window.addEventListener('DOMContentLoaded', function() {
navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia || navigator.msGetUserMedia;
if(navigator.getUserMedia) {
navigator.getUserMedia({video: true, audio: true}, function(stream) {
var video = document.getElementById('sourcevid');
video.src = stream;
}, function(error) {
console.error(error.code);
});
} else {
console.log('Not supported in this browser.');
}
}, false);
</script>
</head>
<body>
<video id="sourcevid" autoplay>Put your fallback message here.</video>
</body>
</html>
请帮助我了解问题出在哪里。
