// StartLabelDetectionRequest returns a request value for making API operation for

// Starts asynchronous detection of labels in a stored video.
//
// Amazon Rekognition Video can detect labels in a video. Labels are instances
// of real-world entities. This includes objects like flower, tree, and table;
// events like wedding, graduation, and birthday party; concepts like landscape,
// evening, and nature; and activities like a person getting out of a car or
// a person skiing.
//
// The video must be stored in an Amazon S3 bucket. Use Video to specify the
// bucket name and the filename of the video. StartLabelDetection returns a
// job identifier (JobId) which you use to get the results of the operation.
// When label 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 label detection operation, first check that the
// status value published to the Amazon SNS topic is SUCCEEDED. If so, call
// GetLabelDetection and pass the job identifier (JobId) from the initial call
// to StartLabelDetection.
