The following example shows you how you can display a user’s webcam feed in a VideoDisplay control using the static Camera.getCamera() method and VideoDisplay class’s attachCamera() method.
Full code after the jump.
This example won’t be very interesting unless you actually have a webcam installed.

</mx:Application>
View source is enabled in the following example.
the else “Alert.show(”You don’t seem to have a camera.”);” isn’t working (Mac OS-X 10.4 iBook PPC - mic but no camera). got prompted to give permissions to access the webcam/microphone though
Right-click the Flash movie, choose Settings.
My Macbook will usually try to open “DV Video” instead of the iSight camera which is “USB Video Class Video”. I suppose there’s a way to make USB the default but I haven’t searched for that.
@Matt. thanx (that actually helped getting a Mac camera working with Connect/Breeze)
but for my iBook (no built-in iSight camera, no camera plugged in at all) all I’m saying is that the “else” doesn’t fire
(selecting which camera won’t work … since there isn’t one at all)
barry.b,
What happens if you compile and run the following code:
<?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" verticalAlign="middle" backgroundColor="white" creationComplete="init();"> <mx:Script> <![CDATA[ import flash.media.Camera; import mx.utils.ObjectUtil; private var camera:Camera; private function init():void { camera = Camera.getCamera(); textArea.text = ObjectUtil.toString(camera); } ]]> </mx:Script> <mx:Label text="{Camera.names} ({Camera.names.length})" /> <mx:TextArea id="textArea" editable="false" width="100%" height="100%" /> </mx:Application>barry.b,
Actually, I quickly converted this into a new entry. Can you check out “Getting specific camera instances using the static Camera.getCamera() method” and tell me what you see?
On my IBM laptop w/ my USB “Logitech QuickCam Express”, I only see one installed camera (my laptop doesn’t have a built-webcam). However, on my iMac w/ built-in iSight, I see three cameras: “DV Video”, “IIDC Firewire Video”, and “USB Video Class Video”.

“However, on my iMac w/ built-in iSight, I see three cameras: “DV Video”, “IIDC Firewire Video”, and “USB Video Class Video”.”
as do I, with no camera attached. I also get the same three options when using Connect (Breeze) and “select a camera”.
is it significant that all three settings show “activityLevel = -1″
Perhaps this is OS X being wishful in it’s thinking? the OS provides a generic three drivers whether the machine it’s installed on has the device or not?
I haven’t been using Mac’s with/without webcams for long, but gut feeling might be an old limitation between Flash and OS X coming back to haunt.
Bottom line however could be that there’s only a test for suitable Mac camera drivers but not the the device itself to be installed and functional. But I’m just guessing…
Hi,
I have some xmls stored in various date folders by the name of yyyymmdd on unix. I have a flex page that that has plots which source data from these xmls using a jsp that has out.println for the xml i want to source. I call this jsp using HTTPSERVICE. I have a datechooser to chose a date depending on which I want to source the xml fromt he folder which depends on the date selected. So, my question is is there a way to reload a flex page with parameters?After choosing a date I want to add this date to the param list passed to the jsp..and I want to refresh my charts with this new jsp url..
I tried javascript:location.reload(true) but it refreshes the page with default date value i.e it doesn;t persist the date value i selected last using the date selector. Please help
Thanks
Out of interest, is there a way to capture a still image from the webcam?
Cheers
Tim
PS: great useful article!!
Sorry it doesnt work for me….it just shows a dark screen, my web cam software clearly captures the video flex is unable to that….
A very nice example for my Webcam - works for me. Thanks a lot!
Thanx this helped me a lot and lucky me that have a brand new webcam :)
Hi,
I have two webcam setup on my PC. Please let me know how to detect all webcams and let the user select one of them.
Thanks for the tutorials/examples.
kevin,
Does this help?
“Getting specific camera instances using the static Camera.getCamera() method”.
Peter
Awesome! Thank you. I really love your examples. Have a great day.
It looks like it cannot get the ’stream’ from a DV camcorder connected. But ! it shows it in the list. I checked with www.acrobat.com and the cam does not work too.
