I want to capture MotionJPG from 2 IP camera and joining together and display it
on applet .
I made this software , but I can capture & display maximum 2 frame per second
which is not good enough for my propose .I want to display at least 15 frame per
second and best is to reach this number to 30 frame per second . I connect both
camera to my private network ( LAN ) , So I don`t think i can do anything on
network side to speed up more . It has to do something with program side .

Here is my code :





import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.net.URL;
import java.net.URLConnection;
import javax.imageio.ImageIO;
import javax.swing.JApplet;

try {
String camera1IP = getParameter("camera1IP");
if (camera1IP == null) {
imageURL1 = new
URL("192.168.11.98/.../image.jpg?&textdisplay=disable");
} else {
imageURL1 = new URL(camera1IP);
}
urlConnection1 = imageURL1.openConnection();
urlConnection1.setDefaultUseCaches(false);
urlConnection1.setRequestProperty("Cache-Control",
"no-store,max-age=0,no-cache");
urlConnection1.setRequestProperty("Expires", "0");
urlConnection1.setRequestProperty("Pragma", "no-cache");
camImg1 = ImageIO.read(imageURL1);

} catch (Exception e) {
System.err.println("Problem in LoadCamNo1 thread : " +
e.toString());
}
try {
sleep(80L);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}

if (Thread.currentThread().getName().equals("LoadCamNo2")) {

}
}

dest.setRGB(i + width1, j, camImg2.getRGB(i,
j));
}
}
