HTML5: camera access

love sunset picture love sunset · Feb 24, 2012 · Viewed 107.4k times · Source

I am quite new to HTML5. I try the following HTML5 code to access camera on my mobile phone. It always display "Native web camera not supported". It seems that my mobile browser (safari and android 2.1 web browser) does not support the camera.

Could you please tell me which browser should I use to access to camera?

<!doctype html>
<html>
<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, maximum-scale=1.0">
    <style>
        body {width: 100%;}
        canvas {display: none;}
    </style>
    <script>
        var video, canvas, msg;
        var load = function () {
            video  = document.getElementById('video');
            canvas = document.getElementById('canvas');
            msg    = document.getElementById('error');
            if( navigator.getUserMedia ) {
                video.onclick = function () {
                    var context = canvas.getContext("2d");
                    context.drawImage(video, 0, 0, 240, 320);
                    var image = {"demo" : {
                        "type"  : "device",
                        "image" : canvas.toDataURL("image/png")
                    }};
                };

                var success = function ( stream ) {
                    video.src = stream;
                };

                var error = function ( err ) {
                    msg.innerHTML = "Error: " + err.code;
                };

                navigator.getUserMedia('video', success, error);

            } else {
                msg.innerHTML = "Native web camera not supported :(";
            }

        };

        window.addEventListener('DOMContentLoaded', load, false);
    </script>
</head>
<body>
    <video  id="video" width="240" height="320" autoplay> </video>
    <p      id="error">Click on the video to send a snapshot to the receiving screen</p>
    <canvas id="canvas" width="240" height="320"> </canvas>
</body>
</html>

The getUserMedia method is now supported on Firefox 17+,Chrome 23+ and Opera 12+. (See caniuse.com)
