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 Detecting faces in a stored video in the Amazon Rekognition Developer Guide.
For .NET Core this operation is only available in asynchronous form. Please refer to StartFaceDetectionAsync.
