Question

我是java编程的初学者。我将在java中播放视频，但卡住了。首先我尝试了vlcj，但它只适用于32位JDK（是不是？）现在我正在使用mpg文件尝试JMF。问题是我只能听到文件的声音，看不到视频。它显示：无法处理格式：MPEG，640x360，FrameRate = 29.9，长度= 345600 我正在使用的代码是：

    import java.awt.BorderLayout;    
    import java.awt.Component;    
    import java.io.File;    
    import java.net.MalformedURLException;    
    import java.net.URL;    
    import javax.media.Manager;    
import javax.media.MediaLocator;    
import javax.media.Player;    
import javax.swing.JFrame;    
import javax.swing.JPanel;    
public class MediaPlayer extends JPanel {    
public MediaPlayer(URL mediauUrl) {

setLayout(new BorderLayout());    
try {

Player mediaPlayer=Manager.createRealizedPlayer(new MediaLocator(mediauUrl));    
Component video=mediaPlayer.getVisualComponent();    
Component control=mediaPlayer.getControlPanelComponent();

if (video!=null) {
    add(video, BorderLayout.CENTER); // place the video component in the panel    
}

add(control, BorderLayout.SOUTH); // place the control in panel    
mediaPlayer.start();    
} catch (Exception e) {    
}    
}
public static void main(String[] args) {

URL mediaUrl=null;    
File file = new File("src/media/Jellyfish.mpg");     

try {    
mediaUrl = file.toURL();    
} catch (MalformedURLException ex) {

System.out.println(ex);    
}

JFrame mediaTest = new JFrame( "Movie Player" );    
mediaTest.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );    
MediaPlayer mediaPanel = new MediaPlayer( mediaUrl );    
mediaTest.add( mediaPanel );

mediaTest.setSize( 800, 700 ); // set the size of the player    
mediaTest.setLocationRelativeTo(null);    
mediaTest.setVisible( true );
}    
}

有人可以帮忙吗？提前致谢
