Initializes a new playback session with an existing dataset.

• Parameter dataset: The playback dataset to use

Starts playback of the dataset.

Playback runs asynchronously on a background queue. Call pause() to stop playback.

pause()

public func pause()

The playback loop will exit on the next iteration after this is called. The current frame index is preserved, so calling run() again will resume from the same position.
