FlashWebCamExample Error 1046

[oferkru]

Hi,

I'm trying to run the lccs FlashWebCamExample on mobile.

I've created an ActionScript Mobile Project and copied the example sources to /src.

Environment is FlashBuilder 4.5 and LCCS 10.3.

I can' build the project due to error 1046: Type was not found or was not a compile-time constant: [mx.core]::IMXMLObject. FlashWebCamExample Unknown Flex Problem.

I also see warnings on WebcamSubscriber.x and WebcamSubscriber.y parameters, seems they have been depracated.

Is there something else instead?

Thanks,

Ofer

OK, here's what I did to create a webcam on a Flex mobile project. Please

note that this will get you started, but is not meant to be

production-quality code!

1. Create a new Flex Mobile Project in FlashBuilder, and accepted the

defaults.

2. Copy the FlashWebCamExample classes into the views folder of your mobile

app.

3. Add a creationComplete handler for the default view:

creationComplete="addCam()"

4. add the following script block to your view:

<fx:Script>

<![CDATA[

import mx.core.UIComponent;

private var flashCam:FlashWebCamExample;

private function addCam():void {

flashCam= new FlashWebCamExample();

var ui:UIComponent = new UIComponent;

addElement(ui);

ui.addChild(flashCam);

}

]]>

</fx:Script>

The FlashWebCamExample class assumes that it gets created on the stage.

Because we're creating it first, then adding it to the stage, we'll need to

make some modifications to get it to run. There's almost certainly a more

elegant way to do this, but it oughtta get you started:

5. In the constructor for FlashWebCamExample, comment out the first three

lines.

6. change the authenticator and roomURL info to match your info.

7. change the last line of the contstructor from stage.addEventListener...

To addEventListener(Event.ADDED_TO_STAGE,setBackGround);

So the quick-and-dirty version of the method (with user info stripped out)

is:

public function FlashWebCamExample()

{

// stage.align = StageAlign.TOP_LEFT;

// stage.scaleMode = StageScaleMode.NO_SCALE;

// setBackGround();

//Login in to your room. Please login as room owner the first

time you run this app , so that all the nodes are created

var authenticator:AdobeHSAuthenticator = new

AdobeHSAuthenticator();

authenticator.userName="username@domain.com";

authenticator.password = "password";

_cSession.roomURL="http://collaboration.adobelivecycle.com/roomUrl";

_cSession.authenticator = authenticator;

_cSession.login();

cSession.addEventListener(SessionEvent.SYNCHRONIZATIONCHANGE,

onLogin);

addEventListener(Event.ADDED_TO_STAGE,setBackGround);

}

I hope that helps.

Hi Sasha,

I tried it and got the following error on FlashWebCamExample.as:

"A file found in a source-path must have the same package structure 'views', as the definition's package, ''. FlashWebCamExample.as /FlashWebCam/src/views Unknown Flex Problem"

any idea?

thanks,

ofer

[sasha_magee]

Add the following to the top of the file:

package views

{

Add a corresponding } at the end.

You may need to do this for all the other .as files you've copied over from

the examples as well.

Thanks

sasha

[oferkru]

Hi Sasha,

Now its running. but when reaching the last line in the ctor: stage.addEventListener(Event.RESIZE,setBackGround);

it crashes saying stage is null.

ofer

[sasha_magee]

As I mentioned (or meant to mention, anyway), you need to change that line

to addEventListener(Event.ADDED_TO_STAGE,setBackGround);

Or, you can actually just comment it out, for simplicity's sake.

[oferkru]

Missed this one,

now I changed and its running.

thanks,

Ofer

Hi Sasha,

On initiation I et th following null pointer exception:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

The full log is bellow.

I verified skype or any other webcam aplication are diabled.

Hi Oferku,

I am guessing your issue, as I am not sure of your setup. Since you are tweaking the FlashWebCamExample, add the following lines on FlashWebCamExample.as file.

Change you onLogin method, to the code below. We are just explicitly setting the connectSession to all the LCCS components that are getting initialized.

          // Add the WebCam Subscriber & the WebCam Publisher.
               _webCamSubscriber = new WebcamSubscriber();
               _webCamSubscriber.width = stage.stageWidth/2;
               _webCamSubscriber.height = stage.stageHeight/2;

                         _webCamSubscriber.connectSession = _cSession;
               _webCamSubscriber.subscribe();               
               // WebCam Publisher
               _webCamPublisher = new WebcamPublisher();

                         _webCamPublisher.connectSession = _cSession;
               //_webCamPublisher.publish();
               _webCamSubscriber.webcamPublisher = _webCamPublisher;
               addChild(_webCamSubscriber);
               
               //SharedProperty for a shared Caption
               _sharedProperty = new SharedProperty();
               _sharedProperty.sharedID = "sharedCaption";
               _sharedProperty.addEventListener(CollectionNodeEvent.SYNCHRONIZATION_CHANGE,onSharedPropSync);
               _sharedProperty.addEventListener(SharedPropertyEvent.CHANGE,onSharedPropChange);

                         _sharedProperty.connectSession = _cSession;
               _sharedProperty.subscribe();

Thanks

Arun

Ofer,

I forgot to mention one additional step you'll need to do (although I do not

believe it's causing the exact problem you've been seeing).

There will be a file in your Flash Builder Project named something like

appname-app.xml.

Near the bottom, there's a section for the android manifest. You'll need to

uncomment the line that reads:

<uses-permission android:name="android.permission.CAMERA"/>

Thanks

Ofer, are you sure you're using the Flash Only version of the LCCS

libraries? Because there should not be any mx components referred to at all.

So either you have used a label in whatever app you are creating, or (more

likely) you're using a flex version of the LCCS libraries. Please check to

make sure you're compiling against the SWC in

com.adobe.lccs/libs/flashOnly/player10.1/lccsFlash.swc

Thanks

sasha

[oferkru]

is there lccsFlash.swc for 10.3 ?

[aponnusa]

Hi,

You could find the lccsFlash swc for 10.3 @ http://forums.adobe.com/thread/860488

Thanks

Arun

I tried it with lccsFlash 10.1.

it won't crash now ,but will just hang, nothing shown on stage...

Are using the Simulator, or are you trying this directly on a device? Do you

see a stop/start button on stage to click?

[oferkru]

Using simulator for now.

No buttons, just white screen.

Ofer

[sasha_magee]

If there's nothing appearing on screen, it seems possible that you have not added the FlashWebCamExample class to the stage.

DO you have a default view in your application?

Did you add the first block of code I mentioned in this message: http://forums.adobe.com/message/3765114#3765114 to it?

Here's the full code of the default view in my test app:

<?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"
        xmlns:s="library://ns.adobe.com/flex/spark" title="HomeView" creationComplete="addCam()">
    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>
<fx:Script>
    <![CDATA[
        import mx.core.UIComponent;
       
        private var flashCam:FlashWebCamExample;

        private function addCam():void {
            flashCam= new FlashWebCamExample();
            var ui:UIComponent = new UIComponent;
            addElement(ui);
            ui.addChild(flashCam);
        }
    ]]>
</fx:Script>
</s:View>

If you've already got this in your default view, I suggest you put a breakpoint in the addCam() method and make sure it's getting called.

[oferkru]

Yap, Its all there.

all initialization methods are called, I verified that.

Ofer

[sasha_magee]

Well, if you're not seeing any stop/start button text, it seems likely that

either the component is not getting added to the stage or it's being located

or sized incorrectly. I'd suggest that you ensure it's all being initialized

correctly by debugging into the constructor and the setBackGround methods.

Thanks

Hi Sasha,

I seems to go through all the GUI initialization methods.

I'm attaching the code.

I appreciate your patience.
