Access camera from a browser
JavascriptCameraJavascript Problem Overview
Is it possible to access the camera (built-in on Apples) from a browser?
Optimal solution would be client-side javascript. Looking to avoid using Java or Flash.
Javascript Solutions
Solution 1 - Javascript
As of 2017, WebKit announces support for WebRTC on Safari
Now you can access them with video and standard javascript WebRTC
E.g.
var video = document.createElement('video');
video.setAttribute('playsinline', '');
video.setAttribute('autoplay', '');
video.setAttribute('muted', '');
video.style.width = '200px';
video.style.height = '200px';
/* Setting up the constraint */
var facingMode = "user"; // Can be 'user' or 'environment' to access back or front camera (NEAT!)
var constraints = {
audio: false,
video: {
facingMode: facingMode
}
};
/* Stream it to video element */
navigator.mediaDevices.getUserMedia(constraints).then(function success(stream) {
video.srcObject = stream;
});
Have a play with it.
Solution 2 - Javascript
The HTML5 spec does allow accessing the webcamera, but last I checked, it is far from finalized, and has very, very little browser support.

You'll probably have to use flash if you want it to work cross-browser.

There is a really cool solution from Danny Markov for that. It uses navigator.getUserMedia method and should work in modern browsers. I have tested it successfully with Firefox and Chrome. IE didn't work:

Possible with HTML5.
Solution 5 - Javascript
Yes it is possible to access the camera from the browser, following is the code that worked for me
<html><head>
</head><body>
<video src="" ></video>
<br />
<button id='flipCamera'>Flip</button>
</body>
<script>
var front = false;
var video = document.querySelector('video');
document.getElementById('flipCamera').onclick = function() { front = !front; };
var constraints = { video: { facingMode: (front? "user" : "environment"), width: 640, height: 480 } };
navigator.mediaDevices.getUserMedia(constraints)
.then(function(mediaStream) {
video.srcObject = mediaStream;
video.onloadedmetadata = function(e) {
video.play();
};
})
.catch(function(err) { console.log(err.name + ": " + err.message); })
</script></html>
Solution 6 - Javascript
You can use HTML5 for this:
<video autoplay></video>
<script>
var onFailSoHard = function(e) {
console.log('Reeeejected!', e);
};
// Not showing vendor prefixes.
navigator.getUserMedia({video: true, audio: true}, function(localMediaStream) {
var video = document.querySelector('video');
video.src = window.URL.createObjectURL(localMediaStream);
// Note: onloadedmetadata doesn't fire in Chrome when using it with getUserMedia.
// See crbug.com/110938.
video.onloadedmetadata = function(e) {
// Ready to go. Do some stuff.
};
}, onFailSoHard);
</script>

#container {
margin: 0px auto;
width: 500px;
height: 375px;
border: 10px #333 solid;
}
#videoElement {
width: 500px;
height: 375px;
background-color: #777;
}
</style>
<div id="container">
<video autoplay="true" id="videoElement"></video>
</div>
<script type="text/javascript">
var video = document.querySelector("#videoElement");
navigator.getUserMedia = navigator.getUserMedia||navigator.webkitGetUserMedia||navigator.mozGetUserMedia||navigator.msGetUserMedia||navigator.oGetUserMedia;
if(navigator.getUserMedia) {
navigator.getUserMedia({video:true}, handleVideo, videoError);
}
function handleVideo(stream) {
video.srcObject=stream;
video.play();
}
function videoError(e) {
}
</script>

Also, you may try the getUserMedia method (supported by Opera 12)
Solution 9 - Javascript
**SIMPLE JAVASCRIPT VANILLA **
var video = document.querySelector("#videoElement");
if (navigator.mediaDevices.getUserMedia) {
navigator.mediaDevices.getUserMedia({ video: true })
.then(function (stream) {
video.srcObject = stream;
})
.catch(function (err0r) {
console.log("Something went wrong!");
});
}
