In the request, you identify the stream name or stream Amazon Resource Name (ARN), and the starting chunk.

Then send the <code>GetMedia</code> requests to this endpoint using the <a href=\"https://docs.aws.amazon.com/cli/latest/reference/\">--endpoint-url parameter</a>. </p> </note> <p>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 <a href=\"https://docs.aws.amazon.com/kinesisvideostreams/latest/dg/API_dataplane_PutMedia.html\">PutMedia</a>. The <code>GetMedia</code> API returns a stream of these chunks starting from the chunk that you specify in the request. </p> <p>The following limits apply when using the <code>GetMedia</code> API:</p> <ul> <li> <p>A client can call <code>GetMedia</code> up to five times per second per stream. </p> </li> <li> <p>Kinesis Video Streams sends media data at a rate of up to 25 megabytes per second (or 200 megabits per second) during a <code>GetMedia</code> session. </p> </li> </ul> <note> <p>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: </p> <ul> <li> <p> <code>x-amz-ErrorType</code> HTTP header – contains a more specific error type in addition to what the HTTP status code provides. </p> </li> <li> <p> <code>x-amz-RequestId</code> HTTP header – if you want to report an issue to AWS, the support team can better diagnose the problem if given the Request Id.</p> </li> </ul> <p>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.</p> <p>For more information, see the <b>Errors</b> section at the bottom of this topic, as well as <a href=\"https://docs.aws.amazon.com/kinesisvideostreams/latest/dg/CommonErrors.html\">Common Errors</a>. </p> </note>"
