Instance Property


The time interval, in seconds, that a player item legible output object messages its delegate earlier than normal.


var advanceIntervalForDelegateInvocation: TimeInterval { get set }


If possible, an AVPlayerItemLegibleOutput instance messages its delegate advanceIntervalForDelegateInvocation seconds earlier than it otherwise would.

If the value provided is large, the delegate methods are invoked as soon as possible.
