使用vlcj同步播放RTP视频和RTP音频

Question

  

需要播放没有任何音频的rtp视频，对于音频，我必须添加一个不同的音频，该音频也是@rtp，因此需要同时播放两者   下面的代码播放@rtp流（视频），现在我也想同步播放也是rtp的音频。

public static void main( String[] args )
       {

        NativeLibrary.addSearchPath(RuntimeUtil.getLibVlcLibraryName(), 
        NATIVE_LIBRARY_SEARCH_PATH);
        System.out.println(LibVlc.INSTANCE.libvlc_get_version());
        String media = "rtp://@239.255.255.10:5004";


        MediaPlayerFactory mediaPlayerFactory = new MediaPlayerFactory(args);
        EmbeddedMediaPlayer mediaPlayer = 
        mediaPlayerFactory.newEmbeddedMediaPlayer();

        Canvas canvas = new Canvas();
        canvas.setBackground(Color.red);
        CanvasVideoSurface videoSurface = 
        mediaPlayerFactory.newVideoSurface(canvas);
        mediaPlayer.setVideoSurface(videoSurface);

        JFrame f = new JFrame("vlcj duplicate output test");
        f.add(canvas);
        f.setSize(800, 600);
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.setVisible(true);

        mediaPlayer.playMedia(media);


        // Don't exit
              try {
            Thread.currentThread().join();
          } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
          }
    }
