Saving image from AVI file

Question

Hello,
I have a piece of sofware using Buffer("bti") to stream live video (avi format). It could save video in avi format also. but now I have a problem that I need to use another buffer ("buf")to get a instant image from the live video and save it at disk. The code as follow:
private void Save() {
     enableComponents(false);
     buttonStart.setLabel("Pause");
     buttonEnd.setEnabled(true);
     Buffer buf = grabberControl.grabFrame();
     if (bti == null || !buf.getFormat().equals(lastSnapFormat)) {
               bti = new BufferToImage((VideoFormat)buf.getFormat());
               lastSnapFormat = buf.getFormat();
     Graphics2D G2D;
Image im = bti.createImage(buf);
biSrc = new BufferedImage (im.getWidth(Spy_Eye.this),im.getHeight(Spy_Eye.this), BufferedImage.TYPE_INT_RGB);
G2D = biSrc.createGraphics();
G2D.drawImage(im, 0, 0, Spy_Eye.this);
biDest = new BufferedImage(im.getWidth(Spy_Eye.this), im.getHeight(Spy_Eye.this), BufferedImage.TYPE_INT_RGB);
if (im != null) {
//Create a fileoutputstream.
FileOutputStream fos;
try{
fos = new FileOutputStream("c:\\myJpeg.jpg");
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(fos);
encoder.encode(biSrc);
fos.flush();
fos.close();
catch(FileNotFoundException e)
{System.out.println(e);}
catch(IOException ioe){System.out.println(ioe);}
if (snapFrame == null){
snapFrame = new SnapFrame(im);
snapFrame.setVisible(true);
snapFrame.setImage(im);
snapFrame.setTitle("Image");
processor.start();
     System.out.println("Image Capture");
The processor.start() control the live stream and that code seems to be hold at "Buffer buf = grabberControl.grabFrame();" and no longer go.
What should I do to improve such code. Please help. I am new to JAVA and JMF. If my description is not clear and anyone seem to be help need more information about those code, pls leave message what kind of information is needed.
Thank you very much.
