How can I scale an OSMF player in ActionScript 3 / Flex

Question

I am trying to create a simple SWF video player using the open source environment in Flex 4. I want to make it dynamically scalable based on the size of the video input by the user. I follow the directions from the Adobe help site , but the video does not seem to scale properly. Depending on the size, sometimes videos play more than the space allocated on the web page, and sometimes less. The only way I was able to get it to work properly was to include a SWF metadata tag that hardcodes width and height, but I can't use it if I want to make the player dynamically. My code is:

package { 
import flash.display.Sprite;
import flash.events.Event;

import org.osmf.media.MediaElement;
import org.osmf.media.MediaPlayer;
import org.osmf.media.URLResource;
import org.osmf.containers.MediaContainer;
import org.osmf.elements.VideoElement;
import org.osmf.layout.LayoutMetadata;

public class GalleryVideoPlayer extends Sprite { 
    private var videoElement:VideoElement; 
    private var mediaPlayer:MediaPlayer;
    private var mediaContainer:MediaContainer;

    private var flashVars:Object;

    public function GalleryVideoPlayer() {
        if (stage) init();
        else addEventListener(Event.ADDED_TO_STAGE, init);
    }

    private function init(e:Event = null):void {
        removeEventListener(Event.ADDED_TO_STAGE, init);

        flashVars = loaderInfo.parameters;

        mediaPlayer = new MediaPlayer();

        videoElement = new VideoElement(new URLResource(flashVars.file));

        mediaContainer = new MediaContainer();

        var layoutMetadata:LayoutMetadata = new LayoutMetadata();
        layoutMetadata.width = Number(flashVars.width);
        layoutMetadata.height = Number(flashVars.height);

        videoElement.addMetadata(LayoutMetadata.LAYOUT_NAMESPACE, layoutMetadata);

        mediaPlayer.media = videoElement;
        mediaContainer.addMediaElement(videoElement); 

        addChild(mediaContainer);
    }
}}
