I want to open a screen and it contains a type of player to run the video that is attached to the project!
I want to open a screen and it contains a type of player to run the video that is attached to the project!
The idea of using JavaFX is interesting. In JavaFX, running a video would look like this:
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
import javafx.scene.media.MediaView;
import javafx.stage.Stage;
public class TocandoVideo extends Application {
private String VIDEO_URL = getClass().getResource(
"/video/creativecommons.mp4").toString();
public static void main(String[] args) {
launch();
}
@Override
public void start(Stage palco) throws Exception {
Media media = new Media(VIDEO_URL); // 1
MediaPlayer mediaPlayer = new MediaPlayer(media); // 2
MediaView mediaView = new MediaView(mediaPlayer); // 3
StackPane raiz = new StackPane();
raiz.getChildren().add(mediaView); // 4
Scene cena = new Scene(raiz, 600, 400);
palco.setTitle("Tocando Video em JavaFX");
palco.setScene(cena);
palco.show();
mediaPlayer.play(); // 4
}
}
As in Playing Video in JavaFX and call class FX within Swing like this:
package dustin.examples;
import javafx.application.Platform;
import javafx.embed.swing.JFXPanel;
import javafx.scene.Scene;
import javax.swing.JFrame;
import javax.swing.SwingUtilities;
/**
* Simple class demonstrating interoperability between Swing and JavaFX. This
* class is adapted from the example provided in the Javadoc documentation for
* {@code javafx.embed.swing.JFXPanel}.
*/

{
private static void initAndShowGUI()
{
// This method is invoked on Swing thread
final JFrame frame = new JFrame("JavaFX / Swing Integrated");
final JFXPanel fxPanel = new JFXPanel();
frame.add(fxPanel);
frame.setVisible(true);
Platform.runLater(new Runnable()
{
@Override
public void run()
{
initFX(fxPanel);
}
});
}
private static void initFX(JFXPanel fxPanel)
{
// This method is invoked on JavaFX thread
final Scene scene = TextIntegrationSceneCreator.createTextScene();
fxPanel.setScene(scene);
}
public static void main(String[] arguments)
{
SwingUtilities.invokeLater(new Runnable()
{
@Override
public void run()
{
initAndShowGUI();
}
});
}
}
As in Integrating JavaFX and Swing .
If the idea is to use even Java, with swing
recommend using the xuggler
link library, there are several examples implemented with this library.
