Videoplayer mit Java erstellen

Ich muss für mein Projekt einen Video-Player mit Java erstellen. Ich habe bereits viele Beispiele im Internet geprüft. Einige davon laufen, zeigen aber keinen Bildschirm, ich kann nur den Ton des Videos hören. Bitte hilf mir das zu lösen ... 

Ich verwende den untenstehenden Import 

import javax.media.*;

EDIT: Unten ist der Code, den ich verwende:

import Java.awt.*;
 import Java.awt.event.*;
 import Java.io.*;
 import javax.swing.*;
 import javax.media.*;

 public class MediaPlayerDemo extends JFrame 
 {
     private Player player;
     private File file;

     public MediaPlayerDemo()
     {
         super( "Demonstrating the Java Media Player" );

         JButton openFile = new JButton( "Open file to play" );
         openFile.addActionListener( new ActionListener() 
         {
             public void actionPerformed( ActionEvent e )
             {
                 openFile();
                 createPlayer();
             }
         });
         getContentPane().add( openFile, BorderLayout.NORTH );

         setSize( 300, 300 );
         show();
     }

     private void openFile()
     {
         JFileChooser fileChooser = new JFileChooser();

         fileChooser.setFileSelectionMode( JFileChooser.FILES_ONLY );
         int result = fileChooser.showOpenDialog( this );

         // user clicked Cancel button on dialog
         if ( result == JFileChooser.CANCEL_OPTION )
             file = null;
         else
             file = fileChooser.getSelectedFile();
     }

     private void createPlayer()
     {
         if ( file == null )
             return;

         removePreviousPlayer();

         try 
         {
             // create a new player and add listener
             player = Manager.createPlayer( file.toURL() );
             player.addControllerListener( new EventHandler() );
             player.start(); // start player
         }
         catch ( Exception e )
         {
             JOptionPane.showMessageDialog( this, "Invalid file or location", "Error loading file",
             JOptionPane.ERROR_MESSAGE );
         }
     }

     private void removePreviousPlayer()
     {
         if ( player == null )
             return;

         player.close();

         Component visual = player.getVisualComponent();
         Component control = player.getControlPanelComponent();

         Container c = getContentPane();

         if ( visual != null )
             c.remove( visual );

         if ( control != null )
             c.remove( control );
     }

     public static void main(String args[])
     {
         MediaPlayerDemo app = new MediaPlayerDemo();

         app.addWindowListener( new WindowAdapter() 
         {
             public void windowClosing( WindowEvent e )
             {
                 System.exit(0);
             }
         });
     }

     // inner class to handler events from media player
     private class EventHandler implements ControllerListener 
     {
         public void controllerUpdate( ControllerEvent e ) 
         {
             if ( e instanceof RealizeCompleteEvent ) 
             {
                 Container c = getContentPane();

                 // load Visual and Control components if they exist
                 Component visualComponent = player.getVisualComponent();

                 if ( visualComponent != null )
                     c.add( visualComponent, BorderLayout.CENTER );

                 Component controlsComponent = player.getControlPanelComponent();

                 if ( controlsComponent != null )
                     c.add( controlsComponent, BorderLayout.SOUTH );

                 c.doLayout();
             }
         }
     }
 }

Ich benutzte vlcj und es funktionierte reibungslos. Es ist eine Java-Bindung an den vlcj-Player, und es ist gut, dass Sie keine Laufwerke angeben müssen, da vlcj alle bereits in der binären Verteilung enthält.

Probieren Sie es aus, es gibt Beispiel für bereits funktionierende Spieler für Sie gebaut!

Versuchen Sie einen JavaFX-Mediaplayer:

Verwendbare Codecs:

  • Audio: MP3; AIFF mit unkomprimiertem PCM; WAV mit unkomprimiertem PCM; Multimedia-Container MPEG-4 mit AAC-Audio (Advanced Audio Coding)
  • Video: FLV mit VP6-Video und MP3-Audio; Multimedia-Container MPEG-4 mit H.264/AVC-Videokomprimierung (Advanced Video Coding).

Hier ein Beispiel von Oracle:

import javafx.application.Application;
import javafx.collections.ListChangeListener;
import javafx.collections.MapChangeListener;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.media.Media;
import javafx.scene.media.MediaView;
import javafx.scene.media.Track;
import javafx.stage.Stage;

/**
 * A sample media player which loops indefinitely over the same video
 */
public class MediaPlayer extends Application {
private static final String MEDIA_URL = "http://someserver/somedir/somefile.mp4";

private static String arg1;

    @Override public void start(Stage stage) {
        stage.setTitle("Media Player");

// Create media player
        Media media = new Media((arg1 != null) ? arg1 : MEDIA_URL);
        javafx.scene.media.MediaPlayer mediaPlayer = new javafx.scene.media.MediaPlayer(media);
        mediaPlayer.setAutoPlay(true);
        mediaPlayer.setCycleCount(javafx.scene.media.MediaPlayer.INDEFINITE);

// Print track and metadata information
        media.getTracks().addListener(new ListChangeListener<Track>() {
public void onChanged(Change<? extends Track> change) {
                System.out.println("Track> "+change.getList());
            }
        });
        media.getMetadata().addListener(new MapChangeListener<String,Object>() {
public void onChanged(MapChangeListener.Change<? extends String, ? extends Object> change) {
                System.out.println("Metadata> "+change.getKey()+" -> "+change.getValueAdded());
            }
        });

// Add media display node to the scene graph
        MediaView mediaView = new MediaView(mediaPlayer);
        Group root = new Group();
        Scene scene = new Scene(root,800,600);
        root.getChildren().add(mediaView);
        stage.setScene(scene);
        stage.show();
    }

public static void main(String[] args) {
if (args.length > 0) {
            arg1 = args[0];
        }
        Application.launch(args);
    }
}

Mit Java Media Framework können Multimediaanwendungen wie Video- und Audioplayer erstellt werden.
