Overview

Package kinesisvideomedia provides the client and types for making API requests to Kinesis Video Media.

See https://docs.aws.amazon.com/goto/WebAPI/kinesis-video-media-2017-09-30 for more information on this service.

See kinesisvideomedia package documentation for more information. https://docs.aws.amazon.com/sdk-for-go/api/service/kinesisvideomedia/

Using the Client

To use Kinesis Video Media with the SDK use the New function to create a new service client. With that client you can make API requests to the service. These clients are safe to use concurrently.

See the SDK's documentation for more information on how to use the SDK. https://docs.aws.amazon.com/sdk-for-go/api/

See aws.Config documentation for more information on configuring SDK clients. https://docs.aws.amazon.com/sdk-for-go/api/aws/#Config

See the Kinesis Video Media client for more information on creating client for this service. https://docs.aws.amazon.com/sdk-for-go/api/service/kinesisvideomedia/#New

Types

type Client added in v0.9.0 

type Client struct {
	*aws.Client
}

Client provides the API operation methods for making requests to Kinesis Video Media. See this package's package overview docs for details on the service.

The client's methods are safe to use concurrently. It is not safe to modify mutate any of the struct's properties though.

func New 

func New(config aws.Config) *Client

New creates a new instance of the client from the provided Config.

Example: 

// Create a client from just a config.
svc := kinesisvideomedia.New(myConfig)

func (*Client) GetMediaRequest added in v0.9.0 

func (c *Client) GetMediaRequest(input *GetMediaInput) GetMediaRequest

GetMediaRequest returns a request value for making 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 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 (https://docs.aws.amazon.com/cli/latest/reference/).

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 (https://docs.aws.amazon.com/kinesisvideostreams/latest/dg/API_dataplane_PutMedia.html). 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 (https://docs.aws.amazon.com/kinesisvideostreams/latest/dg/CommonErrors.html). 

// Example sending a request using GetMediaRequest.
req := client.GetMediaRequest(params)
resp, err := req.Send(context.TODO())
if err == nil {
    fmt.Println(resp)
}

}

Identifies the chunk on the Kinesis video stream where you want the GetMedia API to start returning media data. You have the following options to identify the starting chunk:

  • Choose the latest (or oldest) chunk.

  • Identify a specific chunk. You can identify a specific chunk either by providing a fragment number or timestamp (server or producer).

  • Each chunk's metadata includes a continuation token as a Matroska (MKV) tag (AWS_KINESISVIDEO_CONTINUATION_TOKEN). If your previous GetMedia request terminated, you can use this tag value in your next GetMedia request. The API then starts returning chunks starting where the last API ended.
