type KinesisVideoMedia 

type KinesisVideoMedia struct {
	*client.Client
}

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

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

func New 

func New(p client.ConfigProvider, cfgs ...*aws.Config) *KinesisVideoMedia

New creates a new instance of the KinesisVideoMedia client with a session. If additional configuration is needed for the client instance use the optional aws.Config parameter to add your extra config.

Example: 

// Create a KinesisVideoMedia client from just a session.
svc := kinesisvideomedia.New(mySession)

// Create a KinesisVideoMedia client with additional configuration
svc := kinesisvideomedia.New(mySession, aws.NewConfig().WithRegion("us-west-2"))

func (*KinesisVideoMedia) GetMedia 

func (c *KinesisVideoMedia) GetMedia(input *GetMediaInput) (*GetMediaOutput, error)

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 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).

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.

func (*KinesisVideoMedia) GetMediaRequest 

func (c *KinesisVideoMedia) GetMediaRequest(input *GetMediaInput) (req *request.Request, output *GetMediaOutput)

GetMediaRequest generates a "aws/request.Request" representing the client's request for the GetMedia operation. The "output" return value will be populated with the request's response once the request completes successfully.

Use "Send" method on the returned Request to send the API call to the service. the "output" return value is not valid until after Send returns without error.

See GetMedia for more information on using the GetMedia API call, and error handling.

This method is useful when you want to inject custom logic or configuration into the SDK's request lifecycle. Such as custom headers, or retry logic. 

// Example sending a request using the GetMediaRequest method.
req, resp := client.GetMediaRequest(params)

err := req.Send()
if err == nil { // resp is now filled
    fmt.Println(resp)
}

func (*KinesisVideoMedia) GetMediaWithContext 

func (c *KinesisVideoMedia) GetMediaWithContext(ctx aws.Context, input *GetMediaInput, opts ...request.Option) (*GetMediaOutput, error)

GetMediaWithContext is the same as GetMedia with the addition of the ability to pass a context and additional request options.

See GetMedia for details on how to use this API operation.

The context must be non-nil and will be used for request cancellation. If the context is nil a panic will occur. In the future the SDK may create sub-contexts for http.Requests. See https://golang.org/pkg/context/ for more information on using Contexts.

type StartSelector 

type StartSelector struct {

	// Specifies the fragment number from where you want the GetMedia API to start
	// returning the fragments.
	AfterFragmentNumber *string `min:"1" type:"string"`

	// Continuation token that Kinesis Video Streams returned in the previous GetMedia
	// response. The GetMedia API then starts with the chunk identified by the continuation
	// token.
	ContinuationToken *string `min:"1" type:"string"`

	// Identifies the fragment on the Kinesis video stream where you want to start
	// getting the data from.
	//
	//    * NOW - Start with the latest chunk on the stream.
	//
	//    * EARLIEST - Start with earliest available chunk on the stream.
	//
	//    * FRAGMENT_NUMBER - Start with the chunk after a specific fragment. You
	//    must also specify the AfterFragmentNumber parameter.
	//
	//    * PRODUCER_TIMESTAMP or SERVER_TIMESTAMP - Start with the chunk containing
	//    a fragment with the specified producer or server timestamp. You specify
	//    the timestamp by adding StartTimestamp.
	//
	//    * CONTINUATION_TOKEN - Read using the specified continuation token.
	//
	// If you choose the NOW, EARLIEST, or CONTINUATION_TOKEN as the startSelectorType,
	// you don't provide any additional information in the startSelector.
	//
	// StartSelectorType is a required field
	StartSelectorType *string `type:"string" required:"true" enum:"StartSelectorType"`

	// A timestamp value. This value is required if you choose the PRODUCER_TIMESTAMP
	// or the SERVER_TIMESTAMP as the startSelectorType. The GetMedia API then starts
	// with the chunk containing the fragment that has the specified timestamp.
	StartTimestamp *time.Time `type:"timestamp"`
	// contains filtered or unexported fields
}

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.
