To develop a media application, you must first create a javafx.scene.media
.Media object with the URL source that points to the location of the audio or
video data. The onError function is called if a media error is encountered. These
errors might include media that cannot be located or the media format is unsup-
ported on the platform.

var media = Media {
onError : function(e:MediaError) {
println("got a media error {e}");
}
source :
"http://www.nps.gov/cany/planyourvisit/upload/ClipOne.wmv"

};

After the media object is created, you can query it for certain information. The
duration specifies the total time for playing the media. The height and width
may tell you the resolution of video media unless it cannot be determined, for
example if it is a streaming source or is only audio. The variable metadata holds
any information about the media, such as title and artist. The actual information
varies depending on the media handler.
Next, you need to create a javafx.scene.media.MediaPlayer object. Note that
the MediaPlayer has no visual capability, and you need other scene graph nodes
for the user to control the play. Listing 8.5 shows how to create a MediaPlayer .
