Save the rtp streaming

Question

Hi,
If my data source type is
"com.sun.media.protocol.vfw.DataSource@cd5f8b" ,
I can use the following method to grab the image frome the real-time video that my webcam catpured
cds = (PushBufferDataSource) ds;
cds.getStreams()[0].setTransferHandler(this);
cds.start();
Buffer buf = new Buffer();
public void transferData(PushBufferStream pbs) {
        try {
            pbs.read(buf);
        }catch(java.io.IOException ioe) {
            System.err.println(ioe);
        if (bti == null) {
            VideoFormat vf = (VideoFormat) buf.getFormat();
            bti = new BufferToImage(vf);
        Image im = bti.createImage(buf);
        try
                 BufferedImage tag = new BufferedImage(320,240,BufferedImage.TYPE_INT_RGB);
          tag.getGraphics().drawImage(im,0,0,320,240,null);
                 FileOutputStream out=new FileOutputStream("test.jpg");
                 JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);      
                 encoder.encode(tag);
                 out.close();
          catch(Exception e)
}but if my data source type is "com.sun.media.protocol.rtp.DataSource@14c194d" the previous method does not work.
Does anyone know how should I modify my method when the data source is rtp for grabing image and saving the video?
Thanks!

Having some problems streaming over the internet - probably because im doing it wrong.That's correct, you're doing it wrong.
Im using www.whatismyip.com to get the internet IP of the 2 computers im trying to stream to and from - and using these in the code, but nothing happens.99% of the time, your public IP actually addresses your router, rather than your computer. That means your computer is not publically addressably by it's IP address alone. You'll need to do something called a "NAT holepunch", which you can look up online. Also, I've included two links to discussions I've had with people about the same issue.
