You can work with ScriptCam , a Jquery plugin for webcam use.
Here is a sample code for taking pictures with the webcam:
<!DOCTYPE html>
<html>
<head>
<script language="JavaScript" src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script language="JavaScript" src="//ajax.googleapis.com/ajax/libs/swfobject/2.2/swfobject.js"></script>
<script language="JavaScript" src="scriptcam.js"></script>
<script language="JavaScript">
$(document).ready(function() {
$("#webcam").scriptcam({
showMicrophoneErrors:false,
onError:onError,
cornerRadius:20,
disableHardwareAcceleration:1,
cornerColor:'e3e5e2',
onWebcamReady:onWebcamReady,
uploadImage:'upload.gif',
onPictureAsBase64:base64_tofield_and_image
});
});
function base64_tofield() {
$('#formfield').val($.scriptcam.getFrameAsBase64());
};
function base64_toimage() {
$('#image').attr("src","data:image/png;base64,"+$.scriptcam.getFrameAsBase64());
};
function base64_tofield_and_image(b64) {
$('#formfield').val(b64);
$('#image').attr("src","data:image/png;base64,"+b64);
};
function changeCamera() {
$.scriptcam.changeCamera($('#cameraNames').val());
}
function onError(errorId,errorMsg) {
$( "#btn1" ).attr( "disabled", true );
$( "#btn2" ).attr( "disabled", true );
alert(errorMsg);
}
function onWebcamReady(cameraNames,camera,microphoneNames,microphone,volume) {
$.each(cameraNames, function(index, text) {
$('#cameraNames').append( $('<option></option>').val(index).html(text) )
});
$('#cameraNames').val(camera);
}
</script>
