Я получил ошибку в моей строке 508, где у меня есть этот код

buf = fgc.grabFrame();

CODE:

startC.addActionListener(new ActionListener()
        {           
            @Override
            public void actionPerformed(ActionEvent e)
            {                   
                  // Grab a frame   
                  FrameGrabbingControl fgc = (FrameGrabbingControl) 
                  player.getControl("javax.media.control.FrameGrabbingControl");    
                  buf = fgc.grabFrame();       

              // Convert it to an image 
              BufferToImage btoi = new BufferToImage((VideoFormat)buf.getFormat()); 
              img = btoi.createImage(buf);             

                  // show the image 
                  //imgpanel.setImage(img);       

                  // save image 
                  try {
                    saveJPG(img,"c:\\test.jpg");
                } catch (IOException e1) {
                    // TODO Auto-generated catch block
                    e1.printStackTrace();
                }
}):
