Question

你好朋友我想在JavaFx中播放视频我尝试下面的代码

public class Video extends Application {

@Override
public void start(Stage stage) throws Exception {



    String s=System.getProperty("/home/ubuntu/NetBeansProjects/Video/src"); 
    File f=new File(s, "/media/video.flv");
    Media m=new Media(f.toURI().toString());
    MediaPlayer mp=new MediaPlayer(m);
    MediaView mv=new MediaView(mp);

    StackPane root=new StackPane();
    root.getChildren().add(mv);
    stage.setScene(new Scene(root,400,400));
    stage.setTitle("Video");
    stage.show();
    mp.play();

}


public static void main(String[] args) {
    launch(args);
}

}

我得到的错误就像 MediaException：MEDIA_UNAVAILABLE：/media/video.flv（没有这样的文件或目录）

我解决了哪个方法？

Answer 1

除非在启动java时明确设置它，否则String s=System.getProperty("/home/ubuntu/NetBeansProjects/Video/src");将为null。所以你的代码相当于：

File f=new File("/media/video.flv");

Answer 2

    File f = new File("D:\\Project Files\\Videos\\Business\\Accounting\\Free\\Careers in Accounting.mp4");

    Media media = new Media(f.toURI().toString());
    MediaView mv = new MediaView();

    MediaPlayer mp = new MediaPlayer(media);
    mv.setMediaPlayer(mp);
