# Class MediaPlayer

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

public final class MediaPlayer extends 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, then the event handler registered with the `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 `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 `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.

    public ObjectProperty<Runnable> onErrorProperty
    Event handler invoked when an error occurs.
    See Also:
      - `getOnError()`
      - `setOnError(Runnable)`
      - `onErrorProperty()`

  - ### 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)`
      - `autoPlayProperty()`

  - ### 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)`
      - `rateProperty()`

  - ### 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()`
      - `currentRateProperty()`

  - ### 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)`
      - `volumeProperty()`

  - ### 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)`
      - `balanceProperty()`

  - ### 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)`
      - `startTimeProperty()`

  - ### 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)`
      - `stopTimeProperty()`

  - ### 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()`
      - `cycleDurationProperty()`

  - ### 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()`
      - `totalDurationProperty()`

  - ### 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()`
      - `currentTimeProperty()`

  - ### status

    public ReadOnlyObjectProperty<MediaPlayer.Status> statusProperty
    The current state of the MediaPlayer.
    See Also:
      - `getStatus()`
      - `statusProperty()`

  - ### 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()`
      - `bufferProgressTimeProperty()`

  - ### 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)`
      - `cycleCountProperty()`

  - ### 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()`
      - `currentCountProperty()`

  - ### 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)`
      - `muteProperty()`

  - ### onMarker

    public ObjectProperty<EventHandler<MediaMarkerEvent>> onMarkerProperty

  - ### 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`.

      - `setAudioSpectrumThreshold(int)`
      - `audioSpectrumThresholdProperty()`

  - ### 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.

- ## Constructor Details

  - ### 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:
      `NullPointerException` - if media is `null`.
      `MediaException` - if any synchronous errors occur within the constructor.
