[Java-player-users] Camera compress data never ready

[<mar...@gm...>]

Hello,
I'm having a strange problem with the data from the camera compress device
(device index = 1), it is not ready, except for the first time it runs, so I
can only see one image in the application and after that the while loop goes
forever. When I use the camera device it works fine, there is always data
ready, but I don't know how to show that kind of data as an image.
Sometimes when the program is in the while loop I get this message:

28/09/2007 01:15:41 PM javaclient2.PlayerClient read
WARNING: [PlayerClient]: Unknown message subtype received in read ()

I also know Player is working fine, I have probed it with playercam. So here
is my code:

import java.awt.*;
import java.awt.image.*;
import javax.swing.*;
import java.awt.Graphics;
import java.io.*;
import javax.imageio.*;
import javaclient2.CameraInterface;
import javaclient2.structures.camera.PlayerCameraData;
import javaclient2.PlayerClient;
import javaclient2.PlayerException;
import javaclient2.structures.PlayerConstants;


public class CameraJPEG extends JFrame{

    PlayerClient client = null;
    CameraInterface cami = null;
    PlayerCameraData camera = null;

    BufferedImage image = null;
    static byte[] img;
    InputStream stream;


    public CameraJPEG() {

        super("CameraJPEG");

    Container container = getContentPane();
    container.setLayout(null);
    container.setBackground(new Color(201, 199, 192));

    setBounds(0,0,500,400);
    setVisible(true);

        try{
            client = new PlayerClient("192.168.1.101", 6665);
        cami = client.requestInterfaceCamera(1,
PlayerConstants.PLAYER_OPEN_MODE);
    }
    catch(PlayerException e)
    {
            e.printStackTrace();
    }

        client.setNotThreaded();
        camera = new PlayerCameraData();

        try {
            Thread.sleep (1000);
        }
        catch (Exception e) {}

        while (true)
        {
            repaint();
            client.requestDataDeliveryMode(
PlayerConstants.PLAYER_DATAMODE_PULL);
            client.readAll();
            client.requestAddReplaceRule (-1, -1,
PlayerConstants.PLAYER_MSGTYPE_DATA, -1, 1);
            client.readAll();
            while (!cami.isDataReady ());
            camera = cami.getData();
            img = camera.getImage();
            stream = new ByteArrayInputStream(img,0, camera.getImage_count
());

            try{
                image = ImageIO.read(stream);
            }
            catch(Exception e)
            {
                e.printStackTrace();
            }

            try{
            stream.close();
            }
            catch(IOException e)
            {
                e.printStackTrace();
            }
        }

    }

    public void paint(Graphics g)
    {
        if (image != null)
        {
            g.drawImage(image, 0, 0, null);
        }
        else
        {
            g.clearRect(0, 0, getWidth(), getHeight());
            g.drawString("Please Wait", 50, 100);
        }
    }

    public static void main(String[] args)
    {
        CameraJPEG aplication = new CameraJPEG();
        aplication.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    }

}

So, if anyone can help me i would really appreciate it.
Thanks.
