Client

class KinesisVideo.Client

A low-level client representing Amazon Kinesis Video Streams:

import boto3

client = boto3.client('kinesisvideo')

These are the available methods:

can_paginate(operation_name)

Check if an operation can be paginated.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Returns
True if the operation can be paginated, False otherwise.
create_stream(**kwargs)

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.

See also: AWS API Documentation

Request Syntax

response = client.create_stream(
    DeviceName='string',
    StreamName='string',
    MediaType='string',
    KmsKeyId='string',
    DataRetentionInHours=123
)
Parameters
  • DeviceName (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.

  • StreamName (string) --

    [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.

  • MediaType (string) --

    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.

    To play video on the console, the media must be H.264 encoded, and you need to specify this video type in this parameter as video/h264 .

    This parameter is optional; the default value is null (or empty in JSON).

  • KmsKeyId (string) --

    The ID of the AWS Key Management Service (AWS 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 .

  • DataRetentionInHours (integer) --

    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.

Return type

dict

Returns

Response Syntax

{
    'StreamARN': 'string'
}

Response Structure

  • (dict) --

    • StreamARN (string) --

      The Amazon Resource Name (ARN) of the stream.

delete_stream(**kwargs)

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.

See also: AWS API Documentation

Request Syntax

response = client.delete_stream(
    StreamARN='string',
    CurrentVersion='string'
)
Parameters
  • StreamARN (string) --

    [REQUIRED]

    The Amazon Resource Name (ARN) of the stream that you want to delete.

  • CurrentVersion (string) --

    Optional: The version of the stream that you want to delete.

    Specify the version as a safeguard to ensure that your are deleting the correct stream. To get the stream version, use the DescribeStream API.

    If not specified, only the CreationTime is checked before deleting the stream.

update_data_retention(**kwargs)

Increases or decreases the stream's data retention period by the value that you specify. To indicate whether you want to increase or decrease the data retention period, specify the Operation parameter in the request body. In the request, you must specify either the StreamName or the StreamARN .

Note

The retention period that you specify replaces the current value.

This operation requires permission for the KinesisVideo:UpdateDataRetention action.

Changing the data retention period affects the data in the stream as follows:

  • If the data retention period is increased, existing data is retained for the new retention period. For example, if the data retention period is increased from one hour to seven hours, all existing data is retained for seven hours.
  • If the data retention period is decreased, existing data is retained for the new retention period. For example, if the data retention period is decreased from seven hours to one hour, all existing data is retained for one hour, and any data older than one hour is deleted immediately.
