  1. A word of caution, the MediaStream object shown in the video is ear-marked to be deprecated. You guys can refer to the srcObject property of the HTML5 video element instead. A more up-to-date code snippet using promises looks something like this:

    <video id='target' autoplay></video>

    <script>

    var video = document.getElementById('target');

    navigator.mediaDevices.getUserMedia({
    video: true,
    audio:false
    }).then( stream => {
    video.srcObject = stream;
    video.play();
    }).catch( error => console.log(error) );

    </script>

  6. Hi Alex, I have learn this for a long time and I am doing a research on the streaming system security researching. My professor wants me to build a webcam-server based streaming system, so I install the apache on my ubuntu and do all the exactly same with you, the only thing makes me confused is where u put all this files? in ubuntu, I put them in var/www/html, these three files, but when I type in localhost, is shows nothing, but before that I try the part that "a" between those function, it actually work. And I also try this on my windows desktop, put them in the htdocs folder under the apache24, it still shows nothing. I was wondering if I miss something? or the browers is not supported? or some environment is not installed ? Please help me plz ! Thanks inadvance. Work for a long time on this.
