Playing video with StageWebView, how to stop video (without timer)?

I am using StageWebView to play some video's on a different (numbered) frame, and as of now they only way I can figure out how to kill the video and return to the previous frame is by using a timer to go back after a given amount of time.  This is a bit of a hack, and not optimal, since I want users to be able to stop the video and go back at any time if they choose to.  Any ideas?

Here's the code I currently have on the frame with the video...

import flash.geom.Rectangle;

import flash.media.StageWebView;

import flash.filesystem.File;

stop();

//Timer to next frame

var myTimer1:Timer = new Timer(48000);

myTimer1.addEventListener(TimerEvent.TIMER, fortyeightSec);

myTimer1.start();

function fortyeightSec(event:TimerEvent):void

{

webView1.stage = null;

myTimer1.stop();

MovieClip(root).gotoAndStop(4);

}

//Video Play

var webView1:StageWebView = new StageWebView();

webView1.stage = this.stage;

webView1.viewPort = new Rectangle(0,0,stage.stageWidth,stage.stageHeight);

var fPath1:String = new File(new File("app:/objects.mp4").nativePath).url;

webView1.loadURL( fPath1 );
