如何在java中加载视频FX

-1

我想将视频插入javaFX。从计算机插入视频 - 不是来自YouTube或其他内容。播放/暂停/最小化按钮，不需要边框。如何在java中加载视频FX

import java.io.FileNotFoundException; 
import javafx.application.Application; 
import javafx.scene.Group; 
import javafx.scene.Scene; 
import javafx.scene.media.Media; 
import javafx.scene.media.MediaPlayer; 
import javafx.scene.media.MediaView; 
import javafx.stage.Stage; 

public class MediaMP4 extends Application { 
    Stage window; 
    Scene scene1; 


    public static void main(String[] args) { 
    launch(args); 
} 
@Override 
public void start(Stage primaryStage) throws FileNotFoundException { 

    window = primaryStage; 
    primaryStage.setTitle("Moves"); 


    Media media = new Media ("pr.mp4"); 
    MediaPlayer player = new MediaPlayer (media); 
    MediaView view = new MediaView (player); 


    Group full = new Group(); 
    full.getChildren().addAll(view); 


    scene1 = new Scene (full,600,600); 
    primaryStage.setScene(scene1); 
    window.show(); 

    player.play(); 
    } 
}

我的pr.mp4文件在项目中，而不是在包中。

堆栈跟踪：

控制台滴很长的错误日志。并不播放视频。 –

没有错误日志，我们可能没有太多的事情可做。请包括错误日志 – Gikkman

[编辑]您的问题，以包括[堆栈跟踪]（http://stackoverflow.com/q/3988788/2775450）。确定代码中的哪一行引发异常（您可以在代码中看到行号;我们不能）。 –

在您的堆栈跟踪相关线上：

Caused by: java.lang.IllegalArgumentException: uri.getScheme() == null! uri == 'pr.mp4'。

您需要指定一个带有方案的URI字符串作为construtor参数，如指定的here。

所以从这个更改行：

Media media = new Media ("pr.mp4");

到这样的事情：

Media media = new Media("file://c:/myproject/pr.mp4"));
