// Starts asynchronous detection of segment detection in a stored video. Amazon
// Rekognition Video can detect segments in a video stored in an Amazon S3 bucket.
// Use Video to specify the bucket name and the filename of the video.
// StartSegmentDetection returns a job identifier ( JobId ) which you use to get
// the results of the operation. When segment detection is finished, Amazon
// Rekognition Video publishes a completion status to the Amazon Simple
// Notification Service topic that you specify in NotificationChannel . You can use
// the Filters ( StartSegmentDetectionFilters ) input parameter to specify the
// minimum detection confidence returned in the response. Within Filters , use
// ShotFilter ( StartShotDetectionFilter ) to filter detected shots. Use
// TechnicalCueFilter ( StartTechnicalCueDetectionFilter ) to filter technical
// cues. To get the results of the segment detection operation, first check that
// the status value published to the Amazon SNS topic is SUCCEEDED . if so, call
// GetSegmentDetection and pass the job identifier ( JobId ) from the initial call
// to StartSegmentDetection . For more information, see Detecting video segments in
// stored video in the Amazon Rekognition Developer Guide.
