// GetMedia API operation for Amazon Kinesis Video Streams Media.
//
// Use this API to retrieve media content from a Kinesis video stream. In the
// request, you identify stream name or stream Amazon Resource Name (ARN), and
// the starting chunk. Kinesis Video Streams then returns a stream of chunks
// in order by fragment number.
//
// You must first call the GetDataEndpoint API to get an endpoint to which you
// can then send the GetMedia requests.
//
// When you put media data (fragments) on a stream, Kinesis Video Streams stores
// each incoming fragment and related metadata in what is called a "chunk."
// For more information, see . The GetMedia API returns a stream of these chunks
// starting from the chunk that you specify in the request.
//
// The following limits apply when using the GetMedia API:
//
//    * A client can call GetMedia up to five times per second per stream.
//
//    * Kinesis Video Streams sends media data at a rate of up to 25 megabytes
//    per second (or 200 megabits per second) during a GetMedia session.
//
// Returns awserr.Error for service API and SDK errors. Use runtime type assertions
// with awserr.Error's Code and Message methods to get detailed information about
// the error.
//
// See the AWS API reference guide for Amazon Kinesis Video Streams Media's
// API operation GetMedia for usage and error information.
//
// Returned Error Codes:
//   * ErrCodeResourceNotFoundException "ResourceNotFoundException"
//   Status Code: 404, The stream with the given name does not exist.
//
//   * ErrCodeNotAuthorizedException "NotAuthorizedException"
//   Status Code: 403, The caller is not authorized to perform an operation on
//   the given stream, or the token has expired.
//
//   * ErrCodeInvalidEndpointException "InvalidEndpointException"
//   Status Code: 400, Caller used wrong endpoint to write data to a stream. On
//   receiving such an exception, the user must call GetDataEndpoint with AccessMode
//   set to "READ" and use the endpoint Kinesis Video returns in the next GetMedia
//   call.
//
//   * ErrCodeClientLimitExceededException "ClientLimitExceededException"
//   Kinesis Video Streams has throttled the request because you have exceeded
//   the limit of allowed client calls. Try making the call later.
//
//   * ErrCodeConnectionLimitExceededException "ConnectionLimitExceededException"
//   Kinesis Video Streams has throttled the request because you have exceeded
//   the limit of allowed client connections.
//
//   * ErrCodeInvalidArgumentException "InvalidArgumentException"
//   The value for this input parameter is invalid.
