// bucket. Use Video to specify the bucket name and the filename of the video.
// StartPersonTracking returns a job identifier ( JobId ) which you use to get the

// publishes a completion status to the Amazon Simple Notification Service topic

// detection operation, first check that the status value published to the Amazon
// SNS topic is SUCCEEDED . If so, call GetPersonTracking and pass the job
// identifier ( JobId ) from the initial call to StartPersonTracking .
