//
// Amazon Rekognition Video is a consumer of live video from Amazon Kinesis
// Video Streams. Amazon Rekognition Video sends analysis results to Amazon
// Kinesis Data Streams.
//
// You provide as input a Kinesis video stream (Input) and a Kinesis data stream
// (Output) stream. You also specify the face recognition criteria in Settings.
// For example, the collection containing faces that you want to recognize.
// Use Name to assign an identifier for the stream processor. You use Name to
// manage the stream processor. For example, you can start processing the source
// video by calling StartStreamProcessor with the Name field.
//
// After you have finished analyzing a streaming video, use StopStreamProcessor
// to stop processing. You can delete the stream processor by calling DeleteStreamProcessor.
