Constructors

MediaTimelineController()

Initializes a new instance of the MediaTimelineController class.

Properties

ClockRate	Gets or sets the speed at which the position of the MediaTimelineController changes, expressed as a ratio to normal playback speed. For example, setting a value of 1.0 will result in normal playback speed, a value of 4.0 will result in a playback speed 4 times the normal speed.
Duration	Gets a value indicating the duration of the timeline. After the specified time span has elapsed, the timeline clock will no longer progress.
IsLoopingEnabled	Gets a value indicating whether the timeline will loop, restarting the clock at zero, when it reaches the end of the time window specified by the Duration.
Position	Gets or sets the current position of the MediaTimelineController.
State	Gets a value indicating the current state of the MediaTimelineController, which can be either running or paused.

Methods

Pause()	Pauses playback of the MediaTimelineController.
Resume()	Resumes the playback of the MediaTimelineController from the position at which the controller was paused.
Start()	Starts the playback of the MediaTimelineController from the position 0.

Events

Ended	Occurs when the timeline controller reaches the end of the time window specified by the Duration if IsLoopingEnabled is set to false.
Failed	Occurs when the timeline controller encounters an internal error and can't continue playback.
PositionChanged	Occurs when the position of the MediaTimelineController changes.
StateChanged	Occurs when the state of the MediaTimelineController changes.
