how can I play a video in jme?
edited:
I tried JavaFX and it was not straightforward and has a lot of problems in codecs…
I also used JavaFX webView to play video but not it working correctly because of the video codecs. I expected the web engine to work properly but it did not.
finally, I used SimpleMediaPlayer and it works

Looks like you are in for an adventure.
Maybe this can help you:
You can use JavaFX, or VLC, or about 10 different other ways.
I have to install vlcPlayer for using that way?
Yes.
but it is not straight forward…
what about final user? Does it have to install a vlcPlayer? is not possible to embed vlc dll/so files in a jar file and load it according to os?
The user must have VLC installed, or your “game” must come with an installer that installs it. I don’t know about repackaging VLC. It may or may not be a violation of its license. I have no idea.
do you know who did write the jme-jfx library?
@javasabr and me. And several contributors.
yes, VLCj , you can make a dir containing vlc & attach it to your game dir so users when downloading your game , if they donot have vlc , the one you attached it to your game dir would take over the functionality ,So ,you donot have to repackage it into an installer ,you can take the whole directory of the installed one on your pc , but this will increase your game size , so its better to use jfx video player,
Media media = new Media(path);
MediaPlayer player = new MediaPlayer(media);
player.setAutoPlay(autoplay);
mediaView.setMediaPlayer(player);
mediaView (just a widget with an id that takes in videos) can take over the stop & play actions if you press it(onClickListener) , i donot remember exactly if it creates an auto seekBar for you or donot , but anyway this must run on a jfx context !
I tried to use it to play video but nothing plays.

}I never used javafx in jme, can you share a piece of code that plays a video using jfx and mediaView on a jfx context?
Do you hear something like a music is playing in the background because in jfx media library if you donot attach your video to the MediaView widget you will end up playing it as a music only !
Ingnore the int values , they are acting as switches here !
package DRG208.ConfigsKT;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.control.Button;
import javafx.scene.control.Slider;
import javafx.scene.input.KeyEvent;
import javafx.scene.input.MouseEvent;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
import javafx.scene.media.MediaView;
import javafx.util.Duration;
import javax.swing.*;
import java.awt.event.ActionListener;
import static DRG208.Controller.pressant_1;
public class PlayVideo{
int playing=0;
public PlayVideo(MediaView mediaView, String path, Button playPauseBtn, Slider mediaSlider, boolean autoplay) {
try {
Media media = new Media(path);
MediaPlayer player = new MediaPlayer(media);
player.setAutoPlay(autoplay);
mediaView.setMediaPlayer(player);
mediaView.setOnMouseClicked(event -> {
switch (playing) {
case 1:
player.pause();
playing = 0;
break;
case 0:
player.play();
playing = 1;
break;
}
});
mediaView.setOnKeyTyped(event -> {
switch (event.getCode()){
case G:
player.seek(Duration.seconds(0.2));
JOptionPane.showConfirmDialog(null,"");
break;
}
});
player.play();
playing = 1;
// mediaSlider.setMax(player.getTotalDuration().toMillis());
// Timer t=new Timer(500,action->{
// mediaSlider.adjustValue(player.getVolume());
// });
// t.start();
playPauseBtn.setVisible(true);
playPauseBtn.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
switch (playing) {
case 1:
player.pause();
playing = 0;
break;
case 0:
player.play();
playing = 1;
break;
}
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
}
calling it , focus on the constructor part of the Controller.java , Controller.java is called within th fxml file that holds the front-end & id of widgets:
package DRG208;
import javafx.scene.chart.AreaChart;
import javafx.scene.control.Button;
import javafx.scene.control.Slider;
import javafx.scene.control.TextArea;
import DRG208.ConfigsKT.*;
import javafx.scene.layout.AnchorPane;
import javafx.scene.media.MediaPlayer;
import javafx.scene.media.MediaView;
import javax.swing.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class Controller {
public AreaChart graph;
public TextArea info;
public Button btn;
public MediaView mediaView;
public Button btnPlayPause;
public Button plasmahalflifebtn;
public Slider mediaSlider;
public void Plasma_Half_Life(){
new PlayVideo(mediaView, "file:///E:/Androidprogramming/Videos/Android.mp4", btnPlayPause,null, false);
}
}
EDIT : let me see your code when you finish it beacuse i didnot try this with jme
but the problem is I don’t know how to use JavaFX in jme!
You have to use java-11 and follow the instructions. But the thing is you don’t just want to use javafx to play a video. That’s a very expensive way to play a video. There are other solutions. The only reason you’d want to use JavaFX is if you’re going to use it as a GUI, not to just play videos.
what does this part do , because i cannot see a MediaView here may be this one ?
& whats your stackTrace ?
I think it will change the texture of screen1 to a frame of the playing video.
