2019/12/04 - Amazon Kinesis Video Streams - 9 new api methods
Changes Introduces management of signaling channels for Kinesis Video Streams.
Updates the existing signaling channel. This is an asynchronous operation and takes time to complete.
If the MessageTtlSeconds value is updated (either increased or reduced), then it only applies to new messages sent via this channel after it's been updated. Existing messages are still expire as per the previous MessageTtlSeconds value.

string
[REQUIRED]
The ARN of the signaling channel that you want to update.

Adds one or more tags to a signaling channel. A tag is a key-value pair (the value is optional) that you can define and assign to AWS resources. If you specify a tag that already exists, the tag value is replaced with the value that you specify in the request. For more information, see Using Cost Allocation Tags in the AWS Billing and Cost Management User Guide .

(dict) --
Provides an endpoint for the specified signaling channel to send and receive messages. This API uses the SingleMasterChannelEndpointConfiguration input parameter, which consists of the Protocols and Role properties.
Protocols is used to determine the communication mechanism. For example, specifying WSS as the protocol, results in this API producing a secure websocket endpoint, and specifying HTTPS as the protocol, results in this API generating an HTTPS endpoint.
Role determines the messaging permissions. A MASTER role results in this API generating an endpoint that a client can use to communicate with any of the viewers on the channel. A VIEWER role results in this API generating an endpoint that a client can use to communicate only with a MASTER .

(string) --
Role (string) --
This property is used to determine messaging permissions in this SINGLE_MASTER signaling channel. If MASTER is specified, this API returns an endpoint that a client can use to receive offers from and send answers to any of the viewers on this signaling channel.
