Question

में वीएलसीजे एम्बेड करना मैंने this SO thread पढ़ा है और जब मैंने कुछ बदलावों के साथ कोड का उपयोग करने का प्रयास किया है, तो मुझे सिर्फ एक काला खिड़की मिल रही है, क्या कोई मुझे बता सकता है कि मैं यहाँ क्या कर रहा हूं, मेरे पास सिर्फ एक है मुख्य समारोह के साथ कक्षा:

import java.awt.Color; 
import javax.swing.JFrame; 
import javax.swing.JPanel;

public class Canvas_Demo { 

    // Create a media player factory 
    private MediaPlayerFactory mediaPlayerFactory; 

    // Create a new media player instance for the run-time platform 
    private EmbeddedMediaPlayer mediaPlayer; 

    private JPanel panel; 
    private WindowsCanvas canvas; 
    private JFrame frame;

     mediaPlayer = mediaPlayerFactory.newEmbeddedMediaPlayer(); 
     CanvasVideoSurface videoSurface = mediaPlayerFactory.newVideoSurface(canvas); 
     mediaPlayer.setVideoSurface(videoSurface);

     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
     frame.setLocation(100, 100); 
     frame.setSize(700, 500); 

     //Adding the panel to the 
     frame.add(panel); 
     frame.setVisible(true); 

     //Playing the video

     new Canvas_Demo(url); 

    } 

} 

अग्रिम धन्यवाद।

Answer 1

जब मैं वीडियो url इस (जिन्हें मीडिया Ressource लोकेटर MRL कहा जाता है) को बदल: C:\\MyVideo.mp4 मैं विंडो में वीडियो मिला है।

यह discussion ने मेरी मदद की है।

Answer 2

//Creating the canvas and adding it to the panel : 
canvas = new WindowsCanvas(); 
canvas.setSize(700, 500); 
panel.add(canvas); 

Answer 3

मैं इस तरह

EmbeddedMediaPlayerComponent mediaPlayerComponent = new EmbeddedMediaPlayerComponent(); 
     EmbeddedMediaPlayer embeddedMediaPlayer = mediaPlayerComponent.getMediaPlayer(); 

     Canvas videoSurface = new Canvas(); 
     videoSurface.setBackground(Color.black); 
     videoSurface.setSize(800, 600); 

     List<String> vlcArgs = new ArrayList<String>(); 

     vlcArgs.add("--no-plugins-cache"); 
     vlcArgs.add("--no-video-title-show"); 
     vlcArgs.add("--no-snapshot-preview"); 

     MediaPlayerFactory mediaPlayerFactory = new MediaPlayerFactory(vlcArgs.toArray(new String[vlcArgs.size()])); 
     mediaPlayerFactory.setUserAgent("vlcj test player"); 
     embeddedMediaPlayer.setVideoSurface(mediaPlayerFactory.newVideoSurface(videoSurface)); 
     embeddedMediaPlayer.setPlaySubItems(true); 

     final PlayerControlsPanel controlsPanel = new PlayerControlsPanel(embeddedMediaPlayer); 
     PlayerVideoAdjustPanel videoAdjustPanel = new PlayerVideoAdjustPanel(embeddedMediaPlayer); 

//   mediaPlayerComponent.getMediaPlayer().playMedia(Constant.PATH_ROOT + Constant.PATH_MEDIA + "tmp.mp4"); 
     JFrame mainFrame = new JFrame(); 
     mainFrame.setLayout(new BorderLayout()); 
     mainFrame.setBackground(Color.black); 
     mainFrame.add(videoSurface, BorderLayout.CENTER); 
     mainFrame.add(controlsPanel, BorderLayout.SOUTH); 
     mainFrame.add(videoAdjustPanel, BorderLayout.EAST); 

     //create a button which will hide the panel when clicked. 
     mainFrame.pack(); 
     mainFrame.setVisible(true); 

     embeddedMediaPlayer.playMedia("tmp.mp4");
