  • Init with the data source context.

    Declaration

    Objective-C

    - (nonnull instancetype)initWithContext:(nonnull DataSourceContext *)context;

    Swift

    init(context: DataSourceContext)

  • Pause the playback.

    Declaration

    Objective-C

    - (BOOL)pause;

    Swift

    func pause() -> Bool

  • Resume the playback.

    Declaration

  • Returns the playback state of this data source.

    Declaration

    Objective-C

    - (PlayingStatus)getState;

    Swift

    func getState() -> PlayingStatus

  • Gets the speed multiplier.

    Declaration

    Objective-C
