如何使用vlcj来玩mp4？

import uk.co.caprica.vlcj.player.MediaPlayer;
import uk.co.caprica.vlcj.player.MediaPlayerFactory;

public class MP4Player {
    public static void main(String[] args) {
        String mediaPath = "path/to/your/mp4/file.mp4";
        
        // 创建MediaPlayerFactory对象
        MediaPlayerFactory mediaPlayerFactory = new MediaPlayerFactory();
        
        // 创建MediaPlayer对象
        MediaPlayer mediaPlayer = mediaPlayerFactory.newEmbeddedMediaPlayer();
        
        // 设置视频输出窗口
        mediaPlayer.setVideoSurface(mediaPlayerFactory.newVideoSurface(canvas));
        
        // 播放视频
        mediaPlayer.playMedia(mediaPath);
        
        // 等待视频播放完成
        mediaPlayer.parseMedia();
        
        // 释放资源
        mediaPlayer.release();
        mediaPlayerFactory.release();
    }
}
