Declaration

class AVPlannedSegmentWritingRequest

Overview

AVPlannedSegmentWritingRequest encompasses a request from the AVAssetWritingPlanner to the client code to write one incremental track segment.

The client should respond to this request by writing the specified time range of data to a movie file at the specified segmentFileOutputURL, with start PTS zero. The client’s writing work may be completed asynchronously. If it completes successfully, clients must call the -finish or -finishWithClientState method on the request object. If writing the segment fails, clients must call the -finishWithError: method on the request object. If segment writing needs to be stopped before reaching the end of the segment, clients must call -cancel.
