JoinStorageSession - Amazon Kinesis Video Streams
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).



Before using this API, you must call the GetSignalingChannelEndpoint API to request the WEBRTC endpoint. You then specify the endpoint and region in your JoinStorageSession API request.

Join the ongoing one way-video and/or multi-way audio WebRTC session as a video producing device for an input channel. If there’s no existing session for the channel, a new streaming session needs to be created, and the Amazon Resource Name (ARN) of the signaling channel must be provided.

Currently for the SINGLE_MASTER type, a video producing device is able to ingest both audio and video media into a stream. Only video producing devices can join the session and record media.


Both audio and video tracks are currently required for WebRTC ingestion.

Current requirements:

  • Video track: H.264

  • Audio track: Opus

The resulting ingested video in the Kinesis video stream will have the following parameters: H.264 video and AAC audio.

Once a master participant has negotiated a connection through WebRTC, the ingested media session will be stored in the Kinesis video stream. Multiple viewers are then able to play back real-time media through our Playback APIs.

You can also use existing Kinesis Video Streams features like HLS or DASH playback, image generation via GetImages, and more with ingested WebRTC media.


S3 image delivery and notifications are not currently supported.


Assume that only one video producing device client can be associated with a session for the channel. If more than one client joins the session of a specific channel as a video producing device, the most recent client request takes precedence.
