Resize video with JMF

Question

Im trying to play a video in my java application using JMF. The video is playing fine but im trying to make the video larger. the code below is being placed inside another jpanel with a gridbag layout.

I currently have it being added with no FILL constraint so it should be displaying at its normal size.

When i do add a fill constraint it stretches the video skewing the aspect ratio.

I guess im asking if anyone knows how to resize a video manually or how to lock the aspect ratio

public class VideoPanel extends JPanel{
private Player mediaPlayer;
private File file;

public VideoPanel(String videoFile, String path){
 setOpaque(false);
 file = new File(path+"/video/"+videoFile); 

 URL mediaURL = null;
 try {
  mediaURL = file.toURI().toURL();
 } catch (MalformedURLException e) {
  e.printStackTrace();
 }
 setLayout( new BorderLayout() );      
 Manager.setHint( Manager.LIGHTWEIGHT_RENDERER, true );
 try{
  mediaPlayer = Manager.createRealizedPlayer( mediaURL );
  Component video = mediaPlayer.getVisualComponent();
  Component controls = mediaPlayer.getControlPanelComponent();

  double scale = getScale(this.getWidth(),this.getHeight(),video.getWidth(),video.getHeight());

  video.setPreferredSize(new Dimension((int)scale*video.getWidth(),(int)scale*video.getHeight()));



  if(video != null) 
   add(video,BorderLayout.CENTER );
  if(controls != null) 
   add(controls,BorderLayout.SOUTH );
 }
 catch ( NoPlayerException noPlayerException ){
  System.err.println( "No media player found" );
 }
 catch ( CannotRealizeException cannotRealizeException ){
  System.err.println( "Could not realize media player" );
 }
 catch ( IOException iOException ){
  System.err.println( "Error reading from the source" );
 }
}

private double getScale(int panelWidth, int panelHeight, int imageWidth, int imageHeight) {
 double scale = 1;
 double xScale;
 double yScale;

 xScale = (double) panelWidth / imageWidth;
 yScale = (double) panelHeight / imageHeight;
 scale = Math.min(xScale, yScale);
 return scale;
}

public void stopPlay(){  
 mediaPlayer.stop();
}

}

You may just want to throw the video component in another container panel and control the size from the container. In my app, I have the video component set in a JFrame and to resize the video I simply resize my container.
