Access camera from a browser

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.

If you are just after a camera to take a still photo then just use on a mobile device. See https://stackoverflow.com/a/76922004

As navigator.getUserMedia is deprecated and part of legacy API, use navigator.mediaDevices.getUserMedia instead. It proved to be compatible with Firefox and Chrome:

function loadCamera ()
{
   let v = document.getElementById ("myvideo");
   navigator.mediaDevices.getUserMedia({video:{width:v.width, height:v.height}})
      .then((mediaStream) => {  v.srcObject = mediaStream; })
      .catch(e => { console.error(`${e.name}: ${e.message}`); });

   v.play();
}

loadCamera ();

Also an option is to load it in memory, if the video image is intended to be manipulated or processed before showing, for instance background replacement, or as WebGL2 texture:

function makeVideo (height, width)
{
   let video  = document.createElement ("video");
   video.height      = height;
   video.width       = width;
   video.autoplay    = true;
   video.playsInline = true;
   video.muted       = true;
   video.loop        = true;
   return video;
}
async function loadCamera (height, width)
{
   let v  = makeVideo (height, width);

   navigator.mediaDevices.getUserMedia({video:{width:width, height:height}})
      .then((mediaStream) => {  v.srcObject = mediaStream; })
      .catch(e => { console.error(`${e.name}: ${e.message}`); });

   v.play();
   return v;

}

In then handler add any handling

loadCamera (180, 320).then(video => { document.body.appendChild(video); });

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>

**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!");
        });
}

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.

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:

Here is a demo:

Video Tutorial: Accessing the Camera with HTML5 & appMobi API will be helpful for you.

Also, you may try the getUserMedia method (supported by Opera 12)

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>
