## Class Track

- java.lang.Object
- - javafx.scene.media.Track

- Direct Known Subclasses:
    `AudioTrack`, `SubtitleTrack`, `VideoTrack`

      public abstract class Track
      extends Object

  A class representing a track contained in a media resource. A media resource may have multiple parallel tracks, such as a video track with several audio tracks in different languages. The types of tracks supported by the system may be inferred from the existing subclasses of this class. Not all media resources will contain a track of each supported type, and the time span of a given track need not be commensurate with the time span of the containing media.
  Since:
    JavaFX 2.0
