Flex :: Flash - Detect In App If A Camera Is Already In Use By Another Application?
Mar 30, 2010
I am making an application that plays the video stream from the user's local system (both Windows and Mac). I use the Camera.getCamera() method and in turn Camera.names to get a list of camera attached with the system.
Unfortunately, if the camera is already in use by another application, say a desktop application on user's system, the browser is crashed. Is there any way that I can detect if a specific camera from the list of available camera is already in use by any other application?

From a Flash object, I would like to be able to detect the presence of a webcam that the user might grant access to, without actually asking the user whether they want to grant access. This is to streamline a large application that has extra features if a webcam exists — if there is a webcam, the application will present several dialogs that lead up to the normal cam-security prompt, but if the user doesn't have the hardware, I want to skip over them altogether. Requesting access to the cam before those dialogs won't make sense to the user.
It appears not to be possible to call Camera.getCamera() without the security prompt happening. Is there a workaround? (For instance, could I, perhaps, call getCamera in a hidden Flash object and inspect its return value, or does it block until the user acknowledges the security prompt?)

Let's say I had a flex application (Web, not Air), that was meant for Mass Distribution, to be included like a plug-in of sorts, at various websites. Is there any way for a particular instance of the SWF to detect it's own URL while it's running? If so, can you point me in the right direction of which ActionScript command I might google for more info?

I have a flex mobile application that I am working on that I am having issues with selecting an image from roll/taking a picture. My application is not tabbed, however one part of it contains a Tabbed View Navigator with tabs across the bottom. Within one of those tabs, I have the ability to upload an image to a webservice that I have created. However, when I select an image or take the picture, it pops back out to the initial splash screen and the application restarts. If I use the component standalone (outside of the tabbed view navigator) it selects the image and uploads without any problem.

I'm having trouble with Camera.getCamera() in Flash AS3. If there are multiple camera drivers, it does not necessarily pick the correct one. If the default is the correct, the program works fine; however, if another driver is selected as the default then LED on the webcam does not come on and no video is captured. I can cycle through the available cams and select an arbitrary one. I don't, however, know how to determine if the selected camera is correct. It is not returning null. I considered using camera.currentFPS, but it's not clear when this gets updated. I'm really struggling to determine dynamically which camera will do the trick!

I am having two flash applications on a same web page. Lets say one is already accessing the camera, then if i click on the second application, it will directly start using the camera. I dont want this. I need to check if any other flash application is already accessing the camera in the same web page. Let me tell you that we cant use Camera.getCamera() and check if the camera==null, this wont work, since the camera is available.

Is there a way in Flash to detect if the user has quit the application? For example if the user closes the browser window, or has not been active for 5 minutes, then so remove them from the list of active members.

I've some very old Flash applications, which we don't want to rebuild to add a new feature. We simply need to detect when the user has become idle. So, if the Flash application receives no key or mouse events after 3 minutes, we want to track that time till the user interacts with the application again.
We've considered wrapping the applications in newer Flash applications to include the key/mouse event tracking; however, early research shows that some of our apps are so old that they use event systems or AVM's (ActionScript Virtual Machines) that are incompatible. Also, it seems that mouse events on the inner application don't bubble up to the outer application. (I think the direction of event processing is backwards in versions of Flash prior to 8)
Anyhow, the next idea on the table is to see if we can determine when the user stops interacting with the old Flash applications using JavaScript. Can anyone confirm whether or not it is possible to detect, using JavaScript only, when a swf in an HTML document loses focus or key and mouse events stop and start occurring on the swf?

Another question about the application I'm making. So when the user signs up, he needs to take a picture. I want to do this without using the cameraUI. I followed a sort of tutorial but the application doesn't run. I don't get errors, but the camera doesn't show. Here is what I did:
<?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"

I have a situation where I have to a have a few different sized "cameras" to send over a netstream depending on if its a desktop or mobile connected. Here's how I have it setup:
protected var nearCam:Camera;
protected var nearCamForMobile:Camera;
nearCam = Camera.getCamera();
[Code].....
If i do JUST the nearCamForMobile and send that to the mobile versaion it looks great on the phone and it's not stretched. but then obviously its 480x800 resolution looks stretched on the desktop version which is a 385x240 video box. So if i do just the nearCam it looks great on the desktop but then it looks stretched on the mobile....
So what im curious is why Cant I do both vars the way I showed above, display the nearCam, and then have the nearCamForMobile waiting to be sent when i need it to?
Can you only have one camera mode setup at a time? On the mobile version its setup so the user is holding the phone in potrait and its 840x480. The desktop site looks best when its like a widescreen video.
In the end I'm basically trying to figure out how to have 2 camera vars with 2 resolutions. Display 1 on the near side and attach the other to the netstream in a situation where the far is a mobile client. (I know how to figure out if the far is mobile, im not worried about that part)
I just need to be able to transmit a resolution/aspect ratio that looks good for a mobile client. which happens to be in a different aspect ratio than the desktop cleint.

camera_atual.setQuality(0,100);
camera_atual.setMode(550,480,30,true);

I have a grails application using jquery mobile. I am hoping to find some way to access the camera on the devices. I thought about using flash to grab the webcam but that obviously wont work on Apple devices. Does anyone know of a way to do it and keep it all browser based? I am hoping that there is a plugin somewhere or maybe html5 has some magic in there that supports it.

I have a video capture device on a machine. I have written a windows application to capture the video from this device. While capturing, if i try to broadcast using flash it does not connect. If i'm already broadcasting and then try to capture then my windows application does not get the capture pin of the device. So, flash seems to be taking the capture pin. Is there anyway to broadcast using the preview pin on the device so that i can capture using my application. Or is there way where i can split the capture pin and give one to my app and one to the broadcaster

How do you know if your compiled SWF file has a memory leak?
Are there tools, a firebug setting, etc... to see if there is a problem? I cannot find much in the debug Flash player besides file size and loading time.
I have a large Flash application that I maintain and suspect that is using way too much memory so I wanted to measure the amount of RAM being used while it executes to find key areas to optimize.

Is there a way (in javascript) to detect if an embedded .swf was created with Flash Professional or Flex.We have a page with several tabs, each of which can contain an .swf.All tabs are defined within the same HTML file and the javascript framework calls a .rewind() and .play() on the swf when the containing tab becomes active.This works great on regular flash animation, making sure they start playing from the beginning when the tab is opened. On an swf created with Flex however, the rewind and play wreak havoc on the Flex framework and the application doesn't load.
The best way we've come up with to detect Flex is to count the number of frames the .swf has. With flex that's always 2. But this doesn't sound like the best way.We've also tried to add a callback method with ExternalInterface on the Flex application preinitialize event.Unfortunately this event is called quite late in the application startup and the javasctipt code checks the callback before the Flex code has added it.

My Flex 3 application has some modal dialogs displayed via the PopUpManager, but there are times when I'd like other view components to know there is popup displayed. The PopUpManager doesn't have any method for actually checking the existence of popups. Is there any other way to detect this in flash/flex without writing my own global manager?
(also systemManager.popUpChildren.numChildren == 0 even when there's a modal popup)
