[ aws . kinesis-video-archived-media ]

get-media-for-fragment-list

Description

Gets media for a list of fragments (specified by fragment number) from the archived data in an Amazon Kinesis video stream.

Note

You must first call the GetDataEndpoint API to get an endpoint. Then send the GetMediaForFragmentList requests to this endpoint using the --endpoint-url parameter .

The following limits apply when using the GetMediaForFragmentList API:

  • A client can call GetMediaForFragmentList 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 GetMediaForFragmentList session.

Warning

If an error is thrown after invoking a Kinesis Video Streams archived 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 .

  • AWS_KINESISVIDEO_PRODUCER_SIDE_TIMESTAMP - Producer-side timestamp of the fragment.

The following tags will be included if an exception occurs:
