2017/11/29 - Amazon Kinesis Video Streams - 10 new api methods
Changes Announcing Amazon Kinesis Video Streams, a fully managed video ingestion and storage service. Kinesis Video Streams makes it easy to securely stream video from connected devices to AWS for machine learning, analytics, and processing. You can also stream other time-encoded data like RADAR and LIDAR signals using Kinesis Video Streams.
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.

Request Syntax
client.delete_stream(
StreamARN='string',
CurrentVersion='string'
)
string
[REQUIRED]
The Amazon Resource Name (ARN) of the stream that you want to delete.
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.

Response Structure
(dict) --
Gets an endpoint for a specified stream for either reading or writing. Use this endpoint in your application to read from the specified stream (using the GetMedia or GetMediaForFragmentList operations) or write to it (using the PutMedia operation).
Note
The returned endpoint does not have the API name appended. The client needs to add the API name to the returned endpoint.
In the request, specify the stream either by StreamName or StreamARN .

StreamName='string',
StreamARN='string',
APIName='PUT_MEDIA'|'GET_MEDIA'|'LIST_FRAGMENTS'|'GET_MEDIA_FOR_FRAGMENT_LIST'

Updates stream metadata, such as the device name and media type.
You must provide the stream name or the Amazon Resource Name (ARN) of the stream.
To make sure that you have the latest version of the stream before updating 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.
UpdateStream is an asynchronous operation, and takes time to complete.

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.
