### Configuring a controller

[`func markConfigurationAsFinal()`](/documentation/AVFoundation/AVAssetReaderOutput/RandomAccessController/markConfigurationAsFinal())

Informs the provider that no more reconfiguration of time ranges is necessary and allows the attached AVAssetReader to advance to `AVAssetReaderStatus/completed`.

[`func resetForReading(timeRanges: [CMTimeRange])`](/documentation/AVFoundation/AVAssetReaderOutput/RandomAccessController/resetForReading(timeRanges:))

Starts reading over with a new set of time ranges.
