The IMediaPlaybackController allows controlling audio and video playback.

To create a media playback controller for an existing sound asset, use the createAudioController() method on the IAudioPlaybackControllerFactory interface. To create a media playback controller for an existing audio narration track, use the createPlaybackController() method on the IAudioTrack interface.

To create a media playback controller for an existing MovieClip, use the createEmbeddedVideoController() method on the IVideoPlaybackControllerFactory interface. To create a media playback controller for an FLV/MP4 video, use the createExternalVideoController() method on the IVideoPlaybackControllerFactory interface.

To obtain a media playback controller from an existing video view use the controller property on the IVideoView interface.

Event Detail
mediaPlaybackStateChanged Event

Runtime Versions : AIR 1.0, Flash Player 10.1

Dispatched when the state of the media playback controller is changed.

The MediaPlaybackEvent2.PLAYBACK_STATE_CHANGED constant defines the value of the type property of the event object for a mediaPlaybackStateChanged event. The value of this constant is equal to the value of the MediaPlaybackEvent.PLAYBACK_STATE_CHANGED constant.

The properties of the event object have the following values:

PropertyValue
bubblesfalse
cancelablefalse; there is no default behavior to cancel.
currentTargetThe Object that defines the event listener that handles the event. For example, if you use myButton.addEventListener() to register an event listener, myButton is the value of the currentTarget.
oldPlaybackStateThe old playback state. See the ispring.presenter.player.media.PlaybackState constants for more details.
playbackStateThe new playback state. See the ispring.presenter.player.media.PlaybackState constants for more details.
targetThe Object that dispatched the event; it is not always the Object listening for the event. Use the currentTarget property to always access the Object listening for the event.
