Use this API to retrieve media content from a Kinesis video stream. In the request,
you identify the 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. Then send the
GetMedia requests to this endpoint using the --endpoint-url
parameter.
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 PutMedia.
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.
If an error is thrown after invoking a Kinesis Video Streams media API, in addition to the HTTP status code and the response body, it includes the following pieces of information:
x-amz-ErrorType HTTP header – contains a more specific error type in addition
to what the HTTP status code provides.
x-amz-RequestId HTTP header – if you want to report an issue to AWS, the support
team can better diagnose the problem if given the Request Id.
Both the HTTP status code and the ErrorType header can be utilized to make programmatic decisions about whether errors are retry-able and under what conditions, as well as provide information on what actions the client programmer might need to take in order to successfully try again.
For more information, see the Errors section at the bottom of this topic, as well as Common Errors.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginGetMedia and EndGetMedia.

| Exception | Condition |
|---|---|
| ClientLimitExceededException | Kinesis Video Streams has throttled the request because you have exceeded the limit of allowed client calls. Try making the call later. |
| ConnectionLimitExceededException | Kinesis Video Streams has throttled the request because you have exceeded the limit of allowed client connections. |
| InvalidArgumentException | The value for this input parameter is invalid. |
| 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. |
| NotAuthorizedException | Status Code: 403, The caller is not authorized to perform an operation on the given stream, or the token has expired. |
| ResourceNotFoundException | Status Code: 404, The stream with the given name does not exist. |
