(newbie) video freeze
Hello, I am sorry this is probably a silly question but I can't find any answer in forums on internet so I post it here.
Basically I am develloping a stand-alone application.
I need to display a video (mpeg) stored locally. I use JMF for that.
Using SWING for GUI I used the hint lightweight_renderer for the video to work correctly (error if used in heavy-weight component because I resize the video and it crashes in full screen).
The main problem si now that the video seemed to start with a delay and after some time (always the same, something like 7s on 10s) the video freezes .
I may have some clues,like memory troubles or something like that, but being a real newbie in Java and even in programming I think I need some help.
So please if you have got any clues Ii will be really appreciated.
Thanks by advance and excuse my bad english (french dude!)
Ben

ok I have got some news :
Firstly It seems that there is a problem of synchronisation with my video :
It starts with a black screen for several seconds but the sound starts right at the beginning so the images of the video are delayed basically of several seconds.
My video is included in a JPanel (in lightweight as I said)
here is the code (sorry comments in French, my native tongue!) :
/**
* La classe JPanelContentVideo d閒init un panneau de contenu vid閛 pour le JanelDesktop.
*/
package IHM.navigation;

import java.io.IOException;

import javax.media.ControllerListener;
import javax.media.EndOfMediaEvent;

import javax.media.MediaLocator;
import javax.media.NoPlayerException;
import javax.media.Player;
import javax.media.RealizeCompleteEvent;
import javax.swing.BoxLayout;
import javax.swing.JOptionPane;

The code you posted would not compile here,
let alone run. This variant is an SSCCE, and it
compiels and runs (if you have the JMF installed),
but does not freeze (although it still has serious
layout problems).
Does this code display what you are talking about?
