MediaPlayer (JavaFX 2.2)

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

```
public final class MediaPlayer
extends java.lang.Object
```
The MediaPlayer class provides the controls for playing media. It is used in combination with the Media and MediaView classes to display and control media playback. MediaPlayer does not contain any visual elements so must be used with the MediaView class to view any video track which may be present.
MediaPlayer provides the pause(), play(), stop() and seek() controls as well as the rate and autoPlay properties which apply to all types of media. It also provides the balance, mute, and volume properties which control audio playback characteristics. Further control over audio quality may be attained via the AudioEqualizer associated with the player. Frequency descriptors of audio playback may be observed by registering an AudioSpectrumListener. Information about playback position, rate, and buffering may be obtained from the currentTime, currentRate, and bufferProgressTime properties, respectively. Media marker notifications are received by an event handler registered as the 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 startTime and 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 onRepeat property is invoked. If the stop time is reached and the cycle is not to be repeated, then the event handler registered with the onEndOfMedia property is invoked. A zero-relative index of which cycle is presently being played is maintained by 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 MediaPlayer.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 play() without an intervening invocation of pause() or stop() before the READY transition, as well as setting any of the autoPlay, balance, mute, rate, startTime, stopTime, and volume properties.

The status property may be monitored to make the application aware of player status changes, and callback functions may be registered via properties such as onReady if an action should be taken when a particular status is entered. There are also error and 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 MediaViews. This will not affect the player itself. In particular, the property settings of the view will not have any effect on media playback.

Property Detail
- error
```
public ReadOnlyObjectProperty<MediaException> errorProperty
```
  Observable property set to a MediaException if an error occurs.
  
  See Also:
  getError()
- onError
```
public ObjectProperty<java.lang.Runnable> onErrorProperty
```
  Event handler invoked when an error occurs.
  
  See Also:
  getOnError(), setOnError(Runnable)
- autoPlay
```
public BooleanProperty autoPlayProperty
```
  Whether playing should start as soon as possible. For a new player this will occur once the player has reached the READY state. The default value is false.
  
  See Also:
  isAutoPlay(), setAutoPlay(boolean)
- rate
```
public DoubleProperty rateProperty
```
  The rate at which the media should be played. For example, a rate of 1.0 plays the media at its normal (encoded) playback rate, 2.0 plays back at twice the normal rate, etc. The currently supported range of rates is [0.0, 8.0]. The default value is 1.0.
  
  See Also:
  getRate(), setRate(double)
- currentRate
```
public ReadOnlyDoubleProperty currentRateProperty
```
  The current rate of playback regardless of settings. For example, if rate is set to 1.0 and the player is paused or stalled, then currentRate will be zero.
  
  See Also:
  getCurrentRate()
- volume
```
public DoubleProperty volumeProperty
```
  The volume at which the media should be played. The range of effective values is [0.0 1.0] where 0.0 is inaudible and 1.0 is full volume, which is the default.
  
  See Also:
  getVolume(), setVolume(double)
- balance
```
public DoubleProperty balanceProperty
```
  The balance, or left-right setting, of the audio output. The range of effective values is [-1.0, 1.0] with -1.0 being full left, 0.0 center, and 1.0 full right. The default value is 0.0.
  
  See Also:
  getBalance(), setBalance(double)
- startTime
```
public ObjectProperty<Duration> startTimeProperty
```
  The time offset where media should start playing, or restart from when repeating. When playback is stopped, the current time is reset to this value. If this value is positive, then the first time the media is played there might be a delay before playing begins unless the play position can be set to an arbitrary time within the media. This could occur for example for a video which does not contain a lookup table of the offsets of intra-frames in the video stream. In such a case the video frames would need to be skipped over until the position of the first intra-frame before the start time was reached. The default value is Duration.ZERO.
  Constraints: 0 ≤ startTime < stopTime
  
  See Also:
  getStartTime(), setStartTime(Duration)
- stopTime
```
public ObjectProperty<Duration> stopTimeProperty
```
  The time offset where media should stop playing or restart when repeating. The default value is getMedia().getDuration().
  Constraints: startTime < stopTime ≤ Media.duration
  
  See Also:
  getStopTime(), setStopTime(Duration)
- cycleDuration
```
public ReadOnlyObjectProperty<Duration> cycleDurationProperty
```
  The amount of time between the startTime and stopTime of this player. For the total duration of the Media use the Media.duration property.
  
  See Also:
  getCycleDuration()
- totalDuration
```
public ReadOnlyObjectProperty<Duration> totalDurationProperty
```
  The total amount of play time if allowed to play until finished. If cycleCount is set to INDEFINITE then this will also be INDEFINITE. If the Media duration is UNKNOWN, then this will likewise be UNKNOWN. Otherwise, total duration will be the product of cycleDuration and cycleCount.
  
  See Also:
  getTotalDuration()
- currentTime
```
public ReadOnlyObjectProperty<Duration> currentTimeProperty
```
  The current media playback time. This property is read-only: use seek(javafx.util.Duration) to change playback to a different stream position.
  
  See Also:
  getCurrentTime()
- status
```
public ReadOnlyObjectProperty<MediaPlayer.Status> statusProperty
```
  The current state of the MediaPlayer.
  
  See Also:
  getStatus()
- bufferProgressTime
```
public ReadOnlyObjectProperty<Duration> bufferProgressTimeProperty
```
  The current buffer position indicating how much media can be played without stalling the MediaPlayer. This is applicable to buffered streams such as those reading from network connections as opposed for example to local files.
  Seeking to a position beyond bufferProgressTime might cause a slight pause in playback until an amount of data sufficient to permit playback resumption has been buffered.
  
  See Also:
  getBufferProgressTime()
- cycleCount
```
public IntegerProperty cycleCountProperty
```
  The number of times the media will be played. By default, cycleCount is set to 1 meaning the media will only be played once. Setting cycleCount to a value greater than 1 will cause the media to play the given number of times or until stopped. If set to INDEFINITE, playback will repeat until stop() or pause() is called.
  constraints: cycleCount ≥ 1
  
  See Also:
  getCycleCount(), setCycleCount(int)
- currentCount
```
public ReadOnlyIntegerProperty currentCountProperty
```
  The number of completed playback cycles. On the first pass, the value should be 0. On the second pass, the value should be 1 and so on. It is incremented at the end of each cycle just prior to seeking back to startTime, i.e., when stopTime or the end of media has been reached.
  
  See Also:
  getCurrentCount()
- mute
```
public BooleanProperty muteProperty
```
  Whether the player audio is muted. A value of true indicates that audio is not being produced. The value of this property has no effect on volume, i.e., if the audio is muted and then un-muted, audio playback will resume at the same audible level provided of course that the volume property has not been modified meanwhile. The default value is false.
  
  See Also:
  isMute(), setMute(boolean)
- onMarker
```
public ObjectProperty<EventHandler<MediaMarkerEvent>> onMarkerProperty
```
  Event handler invoked when the player currentTime reaches a media marker.

  See Also:
  getOnHalted(), setOnHalted(Runnable)
- onRepeat
```
public ObjectProperty<java.lang.Runnable> onRepeatProperty
```
  Event handler invoked when the player currentTime reaches stopTime and will be repeating. This callback is made prior to seeking back to startTime.
  
  See Also:
  getOnRepeat(), setOnRepeat(Runnable)
- onStalled
```
public ObjectProperty<java.lang.Runnable> onStalledProperty
```
  Event handler invoked when the status changes to STALLED.
  
  See Also:
  getOnStalled(), setOnStalled(Runnable)
- audioSpectrumNumBands
```
public IntegerProperty audioSpectrumNumBandsProperty
```
  The number of bands in the audio spectrum. The default value is 128; minimum is 2. The frequency range of the audio signal will be divided into the specified number of frequency bins. For example, a typical digital music signal has a frequency range of [0.0, 22050] Hz. If the number of spectral bands were in this case set to 10, the width of each frequency bin in the spectrum would be 2205 Hz with the lower bound of the lowest frequency bin equal to 0.0.

  getAudioSpectrumNumBands(), setAudioSpectrumNumBands(int)
- audioSpectrumInterval
```
public DoubleProperty audioSpectrumIntervalProperty
```

- audioSpectrumThreshold
```
public IntegerProperty audioSpectrumThresholdProperty
```

  See Also:
  getAudioSpectrumThreshold(), setAudioSpectrumThreshold(int)
- audioSpectrumListener
```
public ObjectProperty<AudioSpectrumListener> audioSpectrumListenerProperty
```
  A listener for audio spectrum updates. When the listener is registered, audio spectrum computation is enabled; upon removing the listener, computation is disabled. Only a single listener may be registered, so if multiple observers are required, events must be forwarded.
  An AudioSpectrumListener may be useful for example to plot the frequency spectrum of the audio being played or to generate waveforms for a music visualizer.

  getAudioSpectrumListener(), setAudioSpectrumListener(AudioSpectrumListener)

Field Detail
- INDEFINITE
```
public static final int INDEFINITE
```
  A value representing an effectively infinite number of playback cycles. When cycleCount is set to this value, the player will replay the Media until stopped or paused.
  
  See Also:
  Constant Field Values

Constructor Detail
- MediaPlayer
```
public MediaPlayer(Media media)
```
  Create a player for a specific media. This is the only way to associate a Media object with a MediaPlayer: once the player is created it cannot be changed. Errors which occur synchronously within the constructor will cause exceptions to be thrown. Errors which occur asynchronously will cause the error property to be set and consequently any onError callback to be invoked.
  When created, the status of the player will be MediaPlayer.Status.UNKNOWN. Once the status has transitioned to MediaPlayer.Status.READY the player will be in a usable condition. The amount of time between player creation and its entering READY status may vary depending, for example, on whether the media is being read over a network connection or from a local file system.
  
  Parameters:
  media - The media to play.
  
  Throws:
  
  java.lang.NullPointerException - if media is null.
  
  MediaException - if any synchronous errors occur within the constructor.

The balance, or left-right setting, of the audio output. The range of effective values is [-1.0, 1.0] with -1.0 being full left, 0.0 center, and 1.0 full right. The default value is 0.0.

See Also:
getBalance(), setBalance(double)

setStartTime
```
public final void setStartTime(Duration value)
```
Sets the start time. Its effect will be clamped to the range [Duration.ZERO, stopTime). Invoking this method will have no effect if media duration is Duration.INDEFINITE.

Parameters:
value - the start time

getStartTime
```
public final Duration getStartTime()
```
Retrieves the start time. The default value is Duration.ZERO.

Returns:
the start time

startTimeProperty
```
public ObjectProperty<Duration> startTimeProperty()
```
The time offset where media should start playing, or restart from when repeating. When playback is stopped, the current time is reset to this value. If this value is positive, then the first time the media is played there might be a delay before playing begins unless the play position can be set to an arbitrary time within the media. This could occur for example for a video which does not contain a lookup table of the offsets of intra-frames in the video stream. In such a case the video frames would need to be skipped over until the position of the first intra-frame before the start time was reached. The default value is Duration.ZERO.
Constraints: 0 ≤ startTime < stopTime

See Also:
getStartTime(), setStartTime(Duration)

setStopTime
```
public final void setStopTime(Duration value)
```
Sets the stop time. Its effect will be clamped to the range (startTime, Media.duration]. Invoking this method will have no effect if media duration is Duration.INDEFINITE.

Parameters:
value - the stop time

getStopTime
```
public final Duration getStopTime()
```
Retrieves the stop time. The default value is getMedia().getDuration(). Note that Media.duration may have the value Duration.UNKNOWN if media initialization is not complete.

Returns:
the stop time

stopTimeProperty
```
public ObjectProperty<Duration> stopTimeProperty()
```
The time offset where media should stop playing or restart when repeating. The default value is getMedia().getDuration().
Constraints: startTime < stopTime ≤ Media.duration

See Also:
getStopTime(), setStopTime(Duration)

```
public final Duration getCycleDuration()
```
Retrieves the cycle duration in seconds.

Returns:
the cycle duration

cycleDurationProperty
```
public ReadOnlyObjectProperty<Duration> cycleDurationProperty()
```

See Also:
getCurrentTime()

seek

public void seek(Duration seekTime)

Seeks the player to a new playback time. Invoking this method will have no effect while the player status is MediaPlayer.Status.STOPPED or media duration is Duration.INDEFINITE.

The behavior of seek() is constrained as follows where start time and stop time indicate the effective lower and upper bounds, respectively, of media playback:

seekTime	seek position
`null`	no change
`Duration.UNKNOWN`	no change
`Duration.INDEFINITE`	stop time
seekTime < start time	start time
seekTime > stop time	stop time
start time ≤ seekTime ≤ stop time	seekTime

Parameters:: seekTime - the requested playback time

getStatus
```
public final MediaPlayer.Status getStatus()
```
Retrieves the current player status.

Returns:
the playback status

statusProperty
```
public ReadOnlyObjectProperty<MediaPlayer.Status> statusProperty()
```
The current state of the MediaPlayer.

See Also:
getStatus()

getBufferProgressTime
```
public final Duration getBufferProgressTime()
```
Retrieves the bufferProgressTime value.

Returns:
the buffer progress time

bufferProgressTimeProperty
```
public ReadOnlyObjectProperty<Duration> bufferProgressTimeProperty()
```
The current buffer position indicating how much media can be played without stalling the MediaPlayer. This is applicable to buffered streams such as those reading from network connections as opposed for example to local files.
Seeking to a position beyond bufferProgressTime might cause a slight pause in playback until an amount of data sufficient to permit playback resumption has been buffered.

See Also:
getBufferProgressTime()

setCycleCount
```
public final void setCycleCount(int value)
```
Sets the cycle count. Its effect will be constrained to [1,Integer.MAX_VALUE]. Invoking this method will have no effect if media duration is Duration.INDEFINITE.

getCycleCount
```
public final int getCycleCount()
```
Retrieves the cycle count.

Returns:
the cycle count.

cycleCountProperty
```
public IntegerProperty cycleCountProperty()
```
The number of times the media will be played. By default, cycleCount is set to 1 meaning the media will only be played once. Setting cycleCount to a value greater than 1 will cause the media to play the given number of times or until stopped. If set to INDEFINITE, playback will repeat until stop() or pause() is called.
constraints: cycleCount ≥ 1

See Also:
getCycleCount(), setCycleCount(int)

getCurrentCount
```
public final int getCurrentCount()
```
Retrieves the index of the current cycle.

Returns:

currentCountProperty
```
public ReadOnlyIntegerProperty currentCountProperty()
```
The number of completed playback cycles. On the first pass, the value should be 0. On the second pass, the value should be 1 and so on. It is incremented at the end of each cycle just prior to seeking back to startTime, i.e., when stopTime or the end of media has been reached.

See Also:
