Listing 8.5 MediaPlayer

var mediaPlayer:MediaPlayer = MediaPlayer {
volume: 0.5
autoPlay: false
onError: function(e:MediaError) {
println("got a MediaPlayer error : {e.cause} {e}");
mediaPlayer.stop();
mediaPlayer.media = null;

}
onEndOfMedia: function() {
println("reached end of media");
mediaPlayer.play();
mediaPlayer.stop();
mediaPlayer.media = null;
}
};

This merely creates the player; to use it, you have to set the media variable to a
Media object that points to a source, then invoke the play() , pause() , or stop()
functions to control play. There are several instance variables that you may set on
the MediaPlayer . If autoPlay is true, playing will start right away. The variables
balance , fader , and volume control the left-to-right setting for the audio, the
front-to-back audio setting, and the sound volume. The mute variable toggles the
sound off or on. The onError and onEndOfMedia functions are invoked when an
error occurs or the end of the media is reached. The rate specifies the play
speed, 1.0 being normal speed. There are also functions and variables to report
status, buffering state, and start, stop, and current time settings.
For audio playback, this is all you need to use audio in your application. How-
ever, for video playback, you need a view node, the javafx.scene.media
.MediaView . Listing 8.6 shows how to create a MediaView that can display the
video.

Listing 8.6 MediaView

mv = MediaView {
translateX: bind (scene.width - mv.layoutBounds.width)/2
translateY: bind (scene.height -
mv.layoutBounds.height - bottomBorder)/2
mediaPlayer: bind mediaPlayer
preserveRatio: true
fitWidth: bind scene.width - 4 * borderWidth
fitHeight: bind scene.height - 4 * borderWidth -
bottomBorder
