Photo Booth – Flash Webcam Image Capture
EDIT: From this little experiment a new project called UserBooth came to life 
Two days ago I made a little flash app that will allow anyone to take a picture with a webcam connected to a computer. Everything worked fine in AS3. It was only when I got to the php part of the project when I felt like I should ask for help. And I did, I asked a friend or mine (Mihai Bojin) who in a few minutes explained to me exactly what I needed to know in order to get this project working as it should (a big part of the php code is made by him).
The project is now open source and you can find the code and the source fines underneath
You can download the source files from here:

Here you can see the working application:
vamapaull.com/photobooth
Here you can see the ActionScript 3.0 code:
import flash.display.Bitmap; import flash.display.BitmapData; import com.adobe.images.JPGEncoder; var snd:Sound = new camerasound(); //new sound instance for the "capture" button click var bandwidth:int = 0; // Maximum amount of bandwidth that the current outgoing video feed can use, in bytes per second. var quality:int = 100; // This value is 0-100 with 1 being the lowest quality. var cam:Camera = Camera.getCamera(); cam.setQuality(bandwidth, quality); cam.setMode(320,240,30,false); // setMode(videoWidth, videoHeight, video fps, favor area) var video:Video = new Video(); video.attachCamera(cam); video.x = 20; video.y = 20; addChild(video); var bitmapData:BitmapData = new BitmapData(video.width,video.height); var bitmap:Bitmap = new Bitmap(bitmapData); bitmap.x = 360; bitmap.y = 20; addChild(bitmap); capture_mc.buttonMode = true; capture_mc.addEventListener(MouseEvent.CLICK,captureImage); function captureImage(e:MouseEvent):void { snd.play(); bitmapData.draw(video); save_mc.buttonMode = true; save_mc.addEventListener(MouseEvent.CLICK, onSaveJPG); save_mc.alpha = 1; } save_mc.alpha = .5; function onSaveJPG(e:Event):void{ var myEncoder:JPGEncoder = new JPGEncoder(100); var byteArray:ByteArray = myEncoder.encode(bitmapData); var header:URLRequestHeader = new URLRequestHeader("Content-type", "application/octet-stream"); var saveJPG:URLRequest = new URLRequest("save.php"); saveJPG.requestHeaders.push(header); saveJPG.method = URLRequestMethod.POST; saveJPG.data = byteArray; var urlLoader:URLLoader = new URLLoader(); urlLoader.addEventListener(Event.COMPLETE, sendComplete); urlLoader.load(saveJPG); function sendComplete(event:Event):void{ warn.visible = true; addChild(warn); warn.addEventListener(MouseEvent.MOUSE_DOWN, warnDown); warn.buttonMode = true; } } function warnDown(e:MouseEvent):void{ navigateToURL(new URLRequest("images/"), "_blank"); warn.visible = false; } warn.visible = false;
Here you have the php code:
<?php if(isset($GLOBALS["HTTP_RAW_POST_DATA"])){ $jpg = $GLOBALS["HTTP_RAW_POST_DATA"]; $img = $_GET["img"]; $filename = "images/poza_". mktime(). ".jpg"; file_put_contents($filename, $jpg); } else{ echo "Encoded JPEG information not received."; } ?>

Hi, it looks cool, but doesn’t works for me, the capture works but the save not
, whats the problem with it?
Kind Regards,
Cirke
Hey, I resolved it! I tried to use it without a server, but now works great
Best Regards,
Cirke
Yep, you need a server with php support in order to make it work
Hello, thx for this work !
I tried to adapt your code with an external class, i put this online.
Captures works but save don’t.
It’s not the same problem than Cirke cause i use it on a server.
Can you help me ?
Thx, best.
I tried to put directly your files online and it doesn’t work. Is it a problem with my host ?
it works with java?
Hey there, great app!
I’m trying to update the camera size with no success. I can change the setMode numbers or comment out completely with no effect on the viewing window.
What am I missing?
I need to do the same, but in ASP (not in PHP). Can somebody translate the PHP code to ASP?
Thank you very much!
Does it work with Java?
Nice one.
Thanks for this!
Hello!! It seems good. But even if i clicked on allow. I cannot use the cam.
Hi,
is it possible to set cam an pic size to 100 x 100 pixel ?
can you tell me how does it works ?
Thanks mike
how can i use it in asp.net
Hello,
this is great.
Can you tell me if this code is also proper to make video captures not only photos?
Thanks
@Veronika – the code is made to only make photos. if you want to record video you’ll need a media server first
Hi!
I used this script and it works great, but I also want to send in the same POST description to this photo (some text). Is this possible to do it in the same POST?
Please ask this question on userbooth.com
Not working in Opera 10.61
I asked it on userbooth.com.
I have another question:
This line in PHP code:
$img = $_GET["img"];
what does it do?
Somewhere in AS3script we are sending something named “img” ? I didn’t find any place where this img-sending could be hidden, and IMO this line is useless and doesn’t do anything in fact.
Hi
How can I make this select a predefined camera, like an IP cam or USB camera attached to the server?
This would make it amazingly easy for me to create a photo booth controlled by the web, which I would like to do.
Can it be done?
Thanks
Hi again
I found solution to my problem with sending in the same moment from as3 to php image and other information. The solution is simple:
var desc = “Me and my family”;
var saveJPG:URLRequest = new URLRequest(“save.php?desc=”+desc);
and then on PHP side:
$description = $_GET['desc'];
Hello, I have realized that the script is not working in Google Chrome. Do you have any explanation? Will be you able to solve this issue?
Thanks
@Raul – it’s working fine here: http://www.userbooth.com/demo/?v=snap_cf2b06.jpg
