Media Player error

Question

I am trying to create a Media Player.
Good thing is that using this code i can play mp3 and wmv files correctly.
The problem is that i cant play mp4 files
in fact i can hear the music but cant see its video.
public-read def listView: javafx.scene.control.ListView = javafx.scene.control.ListView {
        disable: false
        layoutX: 60.0
        layoutY: 6.0
        layoutInfo: __layoutInfo_listView
        items: [ "C:\\Users\\JUGAL\\Tera Zikr.mp3", "D:\\Wavin Flag.mp4", "C:\\Users\\Public\\Videos\\Sample Videos\\Wildlife.wmv", ]
        cellFactory: null
function buttonOnMousePressed(event: javafx.scene.input.MouseEvent): Void {
        mediaPlayer.stop();
        var path = listView.selectedItem.toString();
        print(path);
        mediaPlayer.media = if (path == null) then null else
                    Media {
                        source: new File(path).toURI().toString();
                        onError: function(error: javafx.scene.media.MediaError): Void {
                            print(error.message);
                        //mediaErrorLabel.text = error.message;
        slider.min = 0;
        mediaPlayer.play();

Answer 1

Can your computer's default movie player run it correctly? MP4 is not a format that JavaFX supports by default, so it would rely on one of the native back-ends, such as Direct Show (Windows), GStreamer (Linux), and CoreVideo (Mac) to play it.
