Kinesis Video Streams: How it works
You can use Amazon Kinesis Video Streams, a fully managed AWS service, to stream live video from devices to the AWS Cloud and durably store it. You can then build your own applications for real-time video processing or perform batch-oriented video analytics.
The following diagram provides an overview of how Kinesis Video Streams works.
The diagram demonstrates the interaction among the following components:
-
Producer – Any source that puts data into a Kinesis video stream. A producer can be any video-generating device, such as a security camera, a body-worn camera, a smart phone camera, or a dashboard camera. A producer can also send non-video data, such as audio feeds, images, or RADAR data.
A single producer can generate one or more video streams. For example, a video camera can push video data to one Kinesis video stream and audio data to another.
-
Kinesis Video Streams producer libraries – A set of software and libraries that you can install and configure on your devices. You can use these libraries to securely connect and reliably stream video in different ways, including in real time, after buffering it for a few seconds, or as after-the-fact media uploads.

-
Kinesis video stream – A resource that you can use to transport live video data, optionally store it, and make the data available for consumption both in real time and on a batch or one-time basis. In a typical configuration, a Kinesis video stream has only one producer publishing data into it.
The stream can carry audio, video, and similar time-encoded data streams, such as depth sensing feeds, RADAR feeds, and more. You create a Kinesis video stream using the AWS Management Console or programmatically using the AWS SDKs.
Multiple independent applications can consume a Kinesis video stream in parallel.
-
Consumer – Gets data, such as fragments and frames, from a Kinesis video stream to view, process, or analyze it. Generally these consumers are called Kinesis Video Streams applications. You can write applications that consume and process data in Kinesis Video Streams in real time, or after the data is stored and time-indexed when low latency processing isn't required. You can create these consumer applications to run on Amazon EC2 instances.
-
Watch output from cameras using parser library – Enables Kinesis Video Streams applications to reliably get media from Kinesis video stream in a low-latency manner. Additionally, it parses the frame boundaries in the media so that applications can focus on processing and analyzing the frames themselves.
