Compiling SWF runtime from adobeAir application - actionscript-3

Question

I have problem in creating swf file runtime from an adobe air application. For example I create animation using https://github.com/jamesflorentino/Flip-Planes-AS3, I have converted the Sprite extension to MovieClip, the animation runs very good. Now I would like to make the animation could be save as swf file by user.
I have tried as3swf with script like this:
private function createSwf():void{
//let make example the Main class is taken from github above
var _main:Main = new Main();
// in this case i use AS3SWF plugin
var _swf:SWF = new SWF(_main.loaderInfo.bytes);
// this is for copy byteArray from the _swf convertor
var buffer:ByteArray = new ByteArray();
_swf.publish(buffer);
saveToDesktop(buffer);
}
private function saveToDesktop(_ba:ByteArray):void{
// create the file on the desktop
var myFile:File = File.desktopDirectory.resolvePath("demo.swf");
// create a FileStream to write the file
var fs:FileStream = new FileStream();
// add a listener so you know when its finished saving
fs.addEventListener(Event.CLOSE, fileWritten);
// open the file
fs.openAsync(myFile, FileMode.WRITE);
// write the bytearray to it
fs.writeBytes(_ba);
// close the file
fs.close();
}
private function fileWritten(e:Event):void{
trace("new swf file is created");
}
After all those process i got generated swf in my desktop folder with name demo.swf but when i open the file, it is only a white background with error message:
VerifyError: Error #1014: Class flash.events::NativeWindowBoundsEvent could not be found.
at flash.display::MovieClip/nextFrame()

please help me what is the best way to create swf file runtime, both from script side or command line side as long as not server side because it is desktop application.
Many Thanks

Creating a SWF at runtime is not going to be the same as taking an in memory byte array representation of an animation and saving it with a SWF extension.
If you want to build a SWF from AIR; you may consider bundling the Flex Framework with your application and use a NativeProcess to trigger mxmlc to generate a SWF. You'll need source code [or SWCs] to do this, though, it won't work with already compiled assets/classes from your running application.
Or you may want to review the file format for a SWF and go about creating it manually from your AIR application. I have no doubt this is possible, but I do not expect it to be trivial.
