我几天来一直遇到这个问题,无法找到解决方案。
问题是,当我在Eclipse中运行程序时,我的介绍视频会显示并播放,但是当我将其导出到可运行的jar中时,视频不会加载,只有jframe可以加载。
我正在使用带有e(fx)clipse的eclipse。
在我的主类中,我只是创建一个Jframe并将MediaPanel对象添加到Jframe中:
mediaPanel = new MediaPanel( "/videos/Composite2.avi" );
frame.getContentPane().add(mediaPanel);
这是我的MediaPanel类别
import java.awt.BorderLayout;
import java.awt.Component;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import javax.media.CannotRealizeException;
import javax.media.Manager;
import javax.media.NoPlayerException;
import javax.media.Player;
import javax.swing.JPanel;
public class MediaPanel extends JPanel
{
Player mediaPlayer;
public MediaPanel( String mediaURL ) throws MalformedURLException
{
URL mediaURL1 = this.getClass().getResource(mediaURL);
System.out.println(mediaURL1);
setLayout( new BorderLayout() ); // use a BorderLayout
// Use lightweight components for Swing compatibility
Manager.setHint( Manager.LIGHTWEIGHT_RENDERER, true );
try
{
// create a player to play the media specified in the URL
mediaPlayer = Manager.createRealizedPlayer( mediaURL1 );
// get the components for the video and the playback controls
Component video = mediaPlayer.getVisualComponent();
//Component controls = mediaPlayer.getControlPanelComponent();
if ( video != null )
add( video, BorderLayout.CENTER ); // add video component
// if ( controls != null )
//add( controls, BorderLayout.SOUTH ); // add controls
mediaPlayer.start(); // start playing the media clip
} // end try
catch ( NoPlayerException noPlayerException )
{
System.err.println( "No media player found" );
} // end catch
catch ( CannotRealizeException cannotRealizeException )
{
System.err.println( "Could not realize media player" );
} // end catch
catch ( IOException iOException )
{
System.err.println( "Error reading from the source" );
} // end catch
} // end MediaPanel constructor
public void stop(){
mediaPlayer.stop();
}
} // end class MediaPanel
最佳答案
您是否已安装这些库。
dirac-libs-1.0.2-9.fc18.i686.rpm
libavcodec52-0.7.15-32.fc18.i686.rpm
libavformat52-0.7.15-32.fc18.i686.rpm
libavutil50-0.7.15-32.fc18.i686.rpm
libxavs1-0.1.51-2.fc18.i686.rpm
一旦安装了这些,javafx就会像音乐一样播放音乐。
