Creates a new Kinesis video stream.
When you create a new stream, Kinesis Video Streams assigns it a version number. When you change the stream's metadata, Kinesis Video Streams updates the version.
CreateStream is an asynchronous operation.
For information about how the service works, see How it Works .
You must have permissions for the KinesisVideo:CreateStream action.

Tags={
'string': 'string'
}
)
The name of the device that is writing to the stream.
Note
In the current implementation, Kinesis Video Streams does not use this name.
[REQUIRED]
A name for the stream that you are creating.
The stream name is an identifier for the stream, and must be unique for each account and region.
The media type of the stream. Consumers of the stream can use this information when processing the stream. For more information about media types, see Media Types . If you choose to specify the MediaType , see Naming Requirements for guidelines.
Example valid values include "video/h264" and "video/h264,audio/aac".
This parameter is optional; the default value is null (or empty in JSON).
The ID of the Key Management Service (KMS) key that you want Kinesis Video Streams to use to encrypt stream data.
If no key ID is specified, the default, Kinesis Video-managed key (aws/kinesisvideo ) is used.
For more information, see DescribeKey .
The number of hours that you want to retain the data in the stream. Kinesis Video Streams retains the data in a data store that is associated with the stream.
The default value is 0, indicating that the stream does not persist data.
When the DataRetentionInHours value is 0, consumers can still consume the fragments that remain in the service host buffer, which has a retention time limit of 5 minutes and a retention memory limit of 200 MB. Fragments are removed from the buffer when either limit is reached.
A list of tags to associate with the specified stream. Each tag is a key-value pair (the value is optional).

Deletes a Kinesis video stream and the data contained in the stream.
This method marks the stream for deletion, and makes the data in the stream inaccessible immediately.
To ensure that you have the latest version of the stream before deleting it, you can specify the stream version. Kinesis Video Streams assigns a version to each stream. When you update a stream, Kinesis Video Streams assigns a new version number. To get the latest stream version, use the DescribeStream API.
This operation requires permission for the KinesisVideo:DeleteStream action.

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, if you specify WSS as the protocol, this API produces a secure websocket endpoint. If you specify HTTPS as the protocol, this API generates 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 .

To play video on the console, you must specify the correct video type. For example, if the video in the stream is H.264, specify video/h264 as the MediaType .

The available paginators are:
paginator = client.get_paginator('list_signaling_channels')
Creates an iterator that will paginate through responses from KinesisVideo.Client.list_signaling_channels().

Optional: Returns only the channels that satisfy a specific condition.
A comparison operator. Currently, you can only specify the BEGINS_WITH operator, which finds signaling channels whose names begin with a given prefix.
A value to compare.
A dictionary that provides parameters to control pagination.
The total number of items to return. If the total number of items available is more than the value specified in max-items then a NextToken will be provided in the output that you can use to resume pagination.
The size of each page.
A token to specify where to start paginating. This is the NextToken from a previous response.
