A small wrapper library to be able to communicate with a Flash webcam via JavaScript.
Please note: The camera doesn't work if you have any dom-errors on your page!
The Flash object will be embedded into the following Div:
<div id="webcam"></div>jQuery("#webcam").webcam({
width: 320,
height: 240,
mode: "callback",
swffile: "/jscam_canvas_only.swf", // canvas only doesn't implement a jpeg encoder, so the file is much smaller
onTick: function(remain) {
if (0 == remain) {
jQuery("#status").text("Cheese!");
} else {
jQuery("#status").text(remain + " seconds remaining...");
}
},
onSave: function(data) {
var col = data.split(";");
// Work with the picture. Picture-data is encoded as an array of arrays... Not really nice, though =/
},
onCapture: function () {
webcam.save();
// Show a flash for example
},
debug: function (type, string) {
// Write debug information to console.log() or a div, ...
},
onLoad: function () {
// Page load
var cams = webcam.getCameraList();
for(var i in cams) {
jQuery("#cams").append("<li>" + cams[i] + "</li>");
}
}
});
If you want to draw the picture onto a canvas, have a look at the source of the page on my blog, linked below.
