如何在java中加載視頻FX

-1

我想將視頻插入javaFX。從計算機插入視頻 - 不是來自YouTube或其他內容。播放/暫停/最小化按鈕，不需要邊框。如何在java中加載視頻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文件在項目中，而不是在包中。

控制檯滴很長的錯誤日誌。並不播放視頻。 –

沒有錯誤日誌，我們可能沒有太多的事情可做。請包括錯誤日誌 – Gikkman

[編輯]您的問題，以包括[堆棧跟蹤]（http://stackoverflow.com/q/3988788/2775450）。確定代碼中的哪一行引發異常（您可以在代碼中看到行號;我們不能）。 –

在您的堆棧跟蹤相關線上：

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

您需要指定一個帶有方案的URI字符串作爲construtor參數，如指定的here。

所以從這個更改行：

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

到這樣的事情：

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