// Starts asynchronous detection of inappropriate, unwanted, or offensive content
// in a stored video. For a list of moderation labels in Amazon Rekognition, see
// Using the image and video moderation APIs
// (https://docs.aws.amazon.com/rekognition/latest/dg/moderation.html#moderation-api).
// 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 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 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. For more information, see
// Moderating content in the Amazon Rekognition Developer Guide.
