// Starts asynchronous detection of unsafe content in a stored video. Amazon
// Rekognition Video can moderate content in a video stored in an Amazon S3 bucket.
// Use Video () to specify the bucket name and the filename of the video.
// StartContentModeration returns a job identifier (JobId) which you use to get the
// results of the analysis. When unsafe content analysis 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 unsafe content analysis, first check that the status value
// published to the Amazon SNS topic is SUCCEEDED. If so, call GetContentModeration
// () and pass the job identifier (JobId) from the initial call to
// StartContentModeration.  <p>For more information, see Detecting Unsafe Content
// in the Amazon Rekognition Developer Guide.</p>
