I am beginner in Java. I am trying to create a video player with JavaFX, but after running the code, the video won't start. The console, however, is showing no errors.
This is the code:
package application;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.Pane;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
import javafx.scene.media.MediaView;
public class Player extends BorderPane {
Media media;
MediaPlayer player;
MediaView view;
Pane mpane;
public Player(String file){
if (file == null)
return;
media = new Media(file);
player = new MediaPlayer(media);
view = new MediaView(player);
mpane = new Pane();
mpane.getChildren().add(view);
setCenter(mpane);
player.play();
}
}
Main class:
package application;
import javafx.application.Application;
import javafx.scene.*;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
public class Main extends Application {
#Override
public void start(Stage primaryStage) {
Player player = new Player("file:///D:/2013.flv");
Scene scene = new Scene(player, 720, 480, Color.BLACK);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Can anyone help me out?

I'm new to JavaFX and I need to play a video when a button is pressed, but for some reason I can't quite understand, only the sound is played. Here's my code:
package trailer;
import javafx.event.ActionEvent;
import javafx.application.Application;
import javafx.event.EventHandler;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.layout.BackgroundImage;
import javafx.scene.layout.VBox;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
import javafx.scene.media.MediaView;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
public class Trailer extends Application implements EventHandler<ActionEvent>{
Button button;
BackgroundImage image;
MediaPlayer player = new MediaPlayer(new Media(getClass().getResource("videonamehere.mp4").toExternalForm()));
MediaView mediaView = new MediaView(player);
public static void main(String[] args){
launch(args);
}
#Override
public void start(Stage primaryStage) throws Exception{
primaryStage.setTitle("title content");
button = new Button("button name");
button.setOnAction(this);
Label label = new Label("label content");
label.setTextFill(Color.WHITE);
VBox layout = new VBox();
layout.setPadding(new Insets(200));
layout.setSpacing(20);
layout.getChildren().add(button);
layout.getChildren().add(label);
Scene scene = new Scene(layout, 1920, 1080);
primaryStage.setScene(scene);
scene.getStylesheets().add(Trailer.class.getResource("cssfilename.css").toExternalForm();
primaryStage.show();
}
#Override
public void handle(ActionEvent event){
if(event.getSource() == button){
player.play();
}
}
}
To clarify, the interface with the button, the label, and the CSS effects does show up, but when I press the button only the sound from the video plays.
I developed a Media Player in JavaFx and that plays Media with format (.mp4) files.
But, When I try to play (.MKV) files, the player is not working.
How to make this player works with (.MKV) files?
import java.io.File;
import java.io.InputStreamReader;
import java.net.URI;
import java.net.URL;
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.scene.paint.Color;
import javafx.stage.Stage;
public class WmvFileMoviePlayer extends Application{
public static void main (String [] args){
launch(args);
}
#Override
public void start(Stage stage) throws Exception {
Group root = new Group();
try{
Media media = new Media("video/Indian_Sept_2017.wmv");
MediaPlayer player = new MediaPlayer(media);
MediaView view = new MediaView(player);
root.getChildren().add(view);
Scene scene = new Scene(root, 400, 400, Color.BLACK);
stage.setScene(scene);
stage.show();
player.play();
}
catch(Exception e)
{
e.printStackTrace();
}
}}
.wmv is not one of the supported media formats of JavaFX. See here:SupportedMediaTypes
You could try something like this instead: https://github.com/caprica/vlcj-javafx
I'm trying to set an image from a stage snapshot as the stage icon.
The following code demonstrates it:
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.image.WritableImage;
import javafx.scene.layout.Background;
import javafx.scene.layout.BackgroundFill;
import javafx.scene.layout.Pane;
import javafx.scene.layout.StackPane;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
import java.io.IOException;
public class IconTest extends Application {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) throws Exception {
Scene scene = new Scene(new StackPane(new ImageView(generateIcon(32))));
primaryStage.setScene(scene);
primaryStage.getIcons().setAll(generateIcon(32));
primaryStage.show();
}
private static Image generateIcon(int dimension) throws IOException {
Pane root = new Pane();
root.setBackground(new Background(new BackgroundFill(Color.RED, null, null)));
Scene scene = new Scene(root, dimension, dimension);
return scene.snapshot(new WritableImage(dimension, dimension));
}
}
Result:
As you can see, the stage icon is not a red square. Why is that? Loading from a file always works, generating the image using AWT works, too.
Workaround:
BufferedImage bimg = new BufferedImage(dimension, dimension, BufferedImage.TYPE_INT_ARGB);
SwingFXUtils.fromFXImage(scene.snapshot(new WritableImage(dimension, dimension)), bimg);
SwingFXUtils.toFXImage(bimg, new WritableImage(dimension, dimension));
I have this whole mess of Controls and Transitions in the Scene, and whenever an error or message is made, I call FormBuilder.say(String x).
The sample included doesn't error as much, because it's empty. But when all the stuff are active, the pop up from FormBuilder.say(String x) comes out as a mess.
If I wait long enough, attempt to interact, or if I minimize then restore the Stage, it loads properly. But many times, it's just blank.
My laptop runs Ubuntu 15.10, with approx 2GB RAM. No Video Card.
Included is a screen cap of the messy picture.
Included is the code that's affected during the bug. I've striped out some of the less suspected parts. (EDITED)
