/**
* The MediaPlayer
class provides the controls for playing media.
* It is used in combination with the {@link Media} and {@link MediaView}
* classes to display and control media playback. MediaPlayer
does
* not contain any visual elements so must be used with the {@link MediaView}
* class to view any video track which may be present.
*
* MediaPlayer
provides the {@link #pause()}, {@link #play()},
* {@link #stop()} and {@link #seek(javafx.util.Duration) seek()} controls as
* well as the {@link #rateProperty rate} and {@link #autoPlayProperty autoPlay}
* properties which apply to all types of media. It also provides the
* {@link #balanceProperty balance}, {@link #muteProperty mute}, and
* {@link #volumeProperty volume} properties which control audio playback
* characteristics. Further control over audio quality may be attained via the
* {@link AudioEqualizer} associated with the player. Frequency descriptors of
* audio playback may be observed by registering an {@link AudioSpectrumListener}.
* Information about playback position, rate, and buffering may be obtained from
* the {@link #currentTimeProperty currentTime},
* {@link #currentRateProperty currentRate}, and
* {@link #bufferProgressTimeProperty bufferProgressTime}
* properties, respectively. Media marker notifications are received by an event
* handler registered as the {@link #onMarkerProperty onMarker} property.
*
* For finite duration media, playback may be positioned at any point in time
* between 0.0
and the duration of the media. MediaPlayer
* refines this definition by adding the {@link #startTimeProperty startTime} and
* {@link #stopTimeProperty stopTime}
* properties which in effect define a virtual media source with time position
* constrained to [startTime,stopTime]
. Media playback
* commences at startTime
and continues to stopTime
.
* The interval defined by these two endpoints is termed a cycle with
* duration being the difference of the stop and start times. This cycle
* may be set to repeat a specific or indefinite number of times. The total
* duration of media playback is then the product of the cycle duration and the
* number of times the cycle is played. If the stop time of the cycle is reached
* and the cycle is to be played again, the event handler registered with the
* {@link #onRepeatProperty onRepeat} property is invoked. If the stop time is
* reached, then the event handler registered with the {@link #onEndOfMediaProperty onEndOfMedia}
* property is invoked regardless of whether the cycle is to be repeated or not.
* A zero-relative index of which cycle is presently being played is maintained
* by {@link #currentCountProperty currentCount}.
*
*
* The operation of a MediaPlayer
is inherently asynchronous.
* A player is not prepared to respond to commands quasi-immediately until
* its status has transitioned to {@link Status#READY}, which in
* effect generally occurs when media pre-roll completes. Some requests made of
* a player prior to its status being READY
will however take
* effect when that status is entered. These include invoking {@link #play()}
* without an intervening invocation of {@link #pause()} or {@link #stop()}
* before the READY
transition, as well as setting any of the
* {@link #autoPlayProperty autoPlay}, {@link #balanceProperty balance},
* {@link #muteProperty mute}, {@link #rateProperty rate},
* {@link #startTimeProperty startTime}, {@link #stopTimeProperty stopTime}, and
* {@link #volumeProperty volume} properties.
*
* The {@link #statusProperty status}
* property may be monitored to make the application aware of player status
* changes, and callback functions may be registered via properties such as
* {@link #onReadyProperty onReady} if an action should be taken when a particular status is
* entered. There are also {@link #errorProperty error} and {@link #onErrorProperty onError} properties which
* respectively enable monitoring when an error occurs and taking a specified
* action in response thereto.
*
* The same MediaPlayer
object may be shared among multiple
* MediaView
s. This will not affect the player itself. In
* particular, the property settings of the view will not have any effect on
* media playback.
* @see Media
* @see MediaView

status are intentionally not tabulated. UNKNOWN
* is the initial status of the player before the media source is pre-rolled
