// Starts asynchronous detection of faces in a stored video. Amazon Rekognition
// Video can detect faces in a video stored in an Amazon S3 bucket. Use Video to
// specify the bucket name and the filename of the video. StartFaceDetection
// returns a job identifier ( JobId ) that you use to get the results of the
// operation. When face detection is finished, Amazon Rekognition Video publishes a
// completion status to the Amazon Simple Notification Service topic that you
// specify in NotificationChannel . To get the results of the face detection
// operation, first check that the status value published to the Amazon SNS topic
// is SUCCEEDED . If so, call GetFaceDetection and pass the job identifier ( JobId
// ) from the initial call to StartFaceDetection . For more information, see
