hi im quite a newbie at java and wondered if anyone could help, i want
to create a simple media player with stop and play buttons which
display the avi in the centre, when u click play it says "wheres the
file" u find it and it plays central in the screen.
im using the swing classes to do my gui buttons but how can i cross
reference to say use javax media or something, could i call a controll
listener to play the avi files
can some pro please come along and save me, would be willing to pay
for tutorials or help :)

Ben:

You will need Java Media Framework, JMF and you can get it at:

http://java.sun.com/products/java-media/jmf/index.jsp

Below is the test program I use to check my installation and video
files. You should be able to piece together your program from this
outline. You will also need to not use Swing. The components available
in JMF are AWT not Swing.

import java.awt.event.*;

import java.net.*;
import java.util.*;

player.stop();
player.close();
System.exit(0);
}
