Php ming: How to load and access assets from a ming-created swf in Flash/Flex?

Question

Hi! I'm using Ming to create an library swf, using the first code example below. How can I access the embedded png from my Flex application? Here's the php/ming code:

<?php
// Ming to create Library.swf
//-----------------------------------
// Create background...
Ming_setScale(20.0000000);
$movie = new SWFMovie();
ming_useswfversion(7);
$movie->setDimension(550,400);
$movie->setBackground(200, 200, 200);

// Load png file...
$img_file = "src/assets/page0.png";
$png = new SWFBitmap(fopen($img_file, "rb"));

// Add png to movie...
$movie->add($png);

// Export png
$movie->addExport($png, 'png');
$movie->writeExports();

// Save movie to swf
$swfname = dirname(__FILE__);
$swfname .= "/bin-debug/Library.swf";
$movie->save($swfname, 9);

?>

And here's my flex essay:

// Loading Library.swf (works), trying to access png asset (doesn't work)    
private var loader:Loader = new Loader();
private function onCreationComplete():void {
 loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
 loader.load(new URLRequest('Library.swf'));
}
private function onComplete(e:Event):void {
 var resourceClass:Class = loader.contentLoaderInfo.applicationDomain.getDefinition("png") as Class;
}

I'm not sure that the png is exported properly. Testing the Library.swf with SwfUtils code (swfutils.riaforge.org) doesn't show any exported classes at all. Or maybe something else is wrong?

Hi, well I have the same problem I create a library with ming and try to access it from flex and doesn't work.

I've only used this because I needed somehow for an certain url using the Loader class to retrieve the Class object that I can use it to set backgroundImage for a Canvas for example.

But I think that swf exported by ming my have a lower version than the flex compiled swf, and it can't recognize the embedded class name unfortunately.
