Overview

Package kinesisvideosignaling provides the API client, operations, and parameter types for Amazon Kinesis Video Signaling Channels.

Kinesis Video Streams Signaling Service is a intermediate service that establishes a communication channel for discovering peers, transmitting offers and answers in order to establish peer-to-peer connection in webRTC technology.

Functions

func NewDefaultEndpointResolver

func NewDefaultEndpointResolver() *internalendpoints.Resolver

NewDefaultEndpointResolver constructs a new service endpoint resolver

func WithAPIOptions

func WithAPIOptions(optFns ...func(*middleware.Stack) error) func(*Options)

WithAPIOptions returns a functional option for setting the Client's APIOptions option.

func WithEndpointResolver

func WithEndpointResolver(v EndpointResolver) func(*Options)

WithEndpointResolver returns a functional option for setting the Client's EndpointResolver option.

Types

type Client

type Client struct {
	// contains filtered or unexported fields
}

Client provides the API client to make operations call for Amazon Kinesis Video Signaling Channels.

func New

func New(options Options, optFns ...func(*Options)) *Client

New returns an initialized Client based on the functional options. Provide additional functional options to further configure the behavior of the client, such as changing the client's endpoint or adding custom middleware behavior.

func NewFromConfig

func NewFromConfig(cfg aws.Config, optFns ...func(*Options)) *Client

NewFromConfig returns a new client from the provided config.

func (*Client) GetIceServerConfig

func (c *Client) GetIceServerConfig(ctx context.Context, params *GetIceServerConfigInput, optFns ...func(*Options)) (*GetIceServerConfigOutput, error)

Gets the Interactive Connectivity Establishment (ICE) server configuration information, including URIs, username, and password which can be used to configure the WebRTC connection. The ICE component uses this configuration information to setup the WebRTC connection, including authenticating with the Traversal Using Relays around NAT (TURN) relay server. TURN is a protocol that is used to improve the connectivity of peer-to-peer applications. By providing a cloud-based relay service, TURN ensures that a connection can be established even when one or more peers are incapable of a direct peer-to-peer connection. For more information, see A REST API For Access To TURN Services (https://tools.ietf.org/html/draft-uberti-rtcweb-turn-rest-00). You can invoke this API to establish a fallback mechanism in case either of the peers is unable to establish a direct peer-to-peer connection over a signaling channel. You must specify either a signaling channel ARN or the client ID in order to invoke this API.

func (*Client) SendAlexaOfferToMaster

func (c *Client) SendAlexaOfferToMaster(ctx context.Context, params *SendAlexaOfferToMasterInput, optFns ...func(*Options)) (*SendAlexaOfferToMasterOutput, error)

This API allows you to connect WebRTC-enabled devices with Alexa display devices. When invoked, it sends the Alexa Session Description Protocol (SDP) offer to the master peer. The offer is delivered as soon as the master is connected to the specified signaling channel. This API returns the SDP answer from the connected master. If the master is not connected to the signaling channel, redelivery requests are made until the message expires.

type EndpointResolver

type EndpointResolver interface {
	ResolveEndpoint(region string, options EndpointResolverOptions) (aws.Endpoint, error)
}

EndpointResolver interface for resolving service endpoints.

func EndpointResolverFromURL

func EndpointResolverFromURL(url string, optFns ...func(*aws.Endpoint)) EndpointResolver

EndpointResolverFromURL returns an EndpointResolver configured using the provided endpoint url. By default, the resolved endpoint resolver uses the client region as signing region, and the endpoint source is set to EndpointSourceCustom.You can provide functional options to configure endpoint values for the resolved endpoint.

type EndpointResolverFunc

type EndpointResolverFunc func(region string, options EndpointResolverOptions) (aws.Endpoint, error)

EndpointResolverFunc is a helper utility that wraps a function so it satisfies the EndpointResolver interface. This is useful when you want to add additional endpoint resolving logic, or stub out specific endpoints with custom values.

func (EndpointResolverFunc) ResolveEndpoint

func (fn EndpointResolverFunc) ResolveEndpoint(region string, options EndpointResolverOptions) (endpoint aws.Endpoint, err error)

type EndpointResolverOptions

type EndpointResolverOptions = internalendpoints.Options

EndpointResolverOptions is the service endpoint resolver options

type GetIceServerConfigInput

type GetIceServerConfigInput struct {

	// The ARN of the signaling channel to be used for the peer-to-peer connection
	// between configured peers.
	//
	// This member is required.
	ChannelARN *string

	// Unique identifier for the viewer. Must be unique within the signaling channel.
	ClientId *string

}

type Options

type Options struct {
	// Set of options to modify how an operation is invoked. These apply to all
	// operations invoked for this client. Use functional options on operation call to
	// modify this list for per operation behavior.

	// Configures the events that will be sent to the configured logger.
	ClientLogMode aws.ClientLogMode

	// The endpoint options to be used when attempting to resolve an endpoint.
	EndpointOptions EndpointResolverOptions

	// The service endpoint resolver.
	EndpointResolver EndpointResolver

	// Signature Version 4 (SigV4) Signer
	HTTPSignerV4 HTTPSignerV4

	// The logger writer interface to write logging messages to.
	Logger logging.Logger

	// The region to send requests to. (Required)
	Region string

	// Retryer guides how HTTP requests should be retried in case of recoverable
	// failures. When nil the API client will use a default retryer.
	Retryer aws.Retryer

	// The HTTP client to invoke API calls with. Defaults to client's default HTTP
	// implementation if nil.
	HTTPClient HTTPClient
