How to convert BufferedImage?

> why don't you use the code formatting tags?

Sorry, I am posting the codes in code formatting tag again.

hi everyone:

I have created a player using cloned dataSource, after the player has been realized I try to convert a grabbed frame to bufferedImage.

Unfortunately, I got Null value for the image. The codes are follow:

public void takeSnapshot(){

FrameGrabbingControl fgc = null;

snapshotDs = dataSource.cloneCamSource();

try{

snapshotPlayer = Manager.createRealizedPlayer(snapshotDs);

if(snapshotPlayer != null)

snapshotPlayer.start();

}catch (IOException e) {

JOptionPane.showMessageDialog(this,

"Exception creating snapshotPlayer: " + e.getMessage(), "Error", JOptionPane.WARNING_MESSAGE);

return;

}catch (NoPlayerException e) {

JOptionPane.showMessageDialog(this,

"Exception creating snapshotPlayer: " + e.getMessage(), "Error", JOptionPane.WARNING_MESSAGE);

return;

}catch (CannotRealizeException e) {

JOptionPane.showMessageDialog(this,

"Exception creating snapshotPlayer: " + e.getMessage(), "Error", JOptionPane.WARNING_MESSAGE);

return;

}

playhelper = new StateHelper(snapshotPlayer);

if(!playhelper.realize(10000)){

JOptionPane.showMessageDialog(this,

"cannot realize snapshotPlayer", "Error", JOptionPane.WARNING_MESSAGE);

return;

}

if( snapshotPlayer != null)

fgc = (FrameGrabbingControl)snapshotPlayer.getControl("javax.media.control.FrameGrabbingControl");

else

System.err.println("Cannot get FrameGrabbingControl");

Buffer bufferFrame = fgc.grabFrame();

System.out.println("bufferFrame :"+bufferFrame);

BufferToImage bufferToImage = new BufferToImage((VideoFormat)bufferFrame.getFormat());

System.out.println("bufferToImage :"+bufferToImage);

BufferedImage image = (BufferedImage)bufferToImage.createImage(bufferFrame);

if(image != null)

System.out.println("Successful convert image :"+image);

else

System.out.println("Fail to convert image :" + image);

}

and I got the ouputs from terminal window:

bufferFrame :javax.media.Buffer@9b87f6

bufferToImage :javax.media.util.BufferToImage@140b8fd

Fail to convert image :null

Does anyone know why the image is Null value? Can someone help me to fix the problem?

Kinds regards.
