Menu
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>

To integrate webcam with webpage we will use HTML <video> tag.
The getUserMedia method is now supported on Firefox 17+,Chrome 23+ and Opera 12+. (See caniuse.com)

This works on Firefox mobile, Chrome mobile, iPhone and Android:
<input type="file" id="mypic" accept="image/*">
<input type="file" accept="image/*;capture=camera">
See Capturing Audio & Video in HTML5
Support:
- Android 3.0 browser - one of the first implementations. Check out this video to see it in action.
- Chrome for Android (0.16)
- Firefox Mobile 10.0
- iOS6 Safari and Chrome (partial support)

We've had some success with this basic approach cobbled together from across the Web:
<form method="post" action="takephoto.php" enctype="multipart/form-data">
<input type="file" accept="image/*" name="file">
<input type="submit">
</form>
Then in the PHP file we generate unique file names using now() or something similar for storage.
