Amazon Kinesis Video Streams with WebRTC

Kinesis Video Streams also supports real-time media streaming via WebRTC. WebRTC is an open-source project that incorporates the required technology for real time communication (RTC) of audio, video and data in web and native apps via APIs. WebRTC is supported on all major browsers on desktops, laptops, tablets and smart phones. Libraries supporting WebRTC make it straightforward to add WebRTC support to a mobile phone or desktop app without the need of custom plugins. Media streams are secure and encrypted with Secure Real Time Protocol (SRTP).

Kinesis Video Streams provides a standards-compliant WebRTC implementation as a fully managed capability. You can use Kinesis Video Streams with WebRTC to securely live stream media or perform two-way audio or video interaction between any camera IoT device and WebRTC-compliant mobile or web players. As a fully managed capability, you don’t have to build, operate, or scale any WebRTC-related cloud infrastructure, such as signaling or media relay servers to securely stream media across applications and devices.

Using Kinesis Video Streams with WebRTC, you can easily build applications for live peer-to-peer media streaming, or real-time audio or video interactivity between camera IoT devices, web browsers, and mobile devices for a variety of use cases. Typical use cases include interactive video and audio between a video doorbell or baby monitor or your automobile and your mobile phone, video chat and peer-to-peer media streaming. Some advanced automotive use-cases include: a) high-definition sensor sharing – AV lane change, b) see-through for pass maneuvers, c) tele-operated driving, d) obstructed view assist, e) infrastructure assisted environment perception (requirements from 5G Automotive Association).


Comparison of Kinesis Video Streams with WebRTC and Kinesis Video Streams

Kinesis Video Streams with WebRTC is for real time communication, which is defined as sub-second latency and 2-way communication. Kinesis Video Streams with WebRTC current implementation supports 1:1 or 1:N scenarios. For 1 to N communication, each stream is unique. You cannot ingest data into the cloud for storage or processing through this capability. Kinesis Video Streams can ingest audio and video and throttles based on the number of fragments requested rather than the number of playback sessions. This gives developers the flexibility to enable up to 10x more simultaneous playback sessions for applications that use Kinesis Video Streams for live or on-demand playback. Kinesis Video Streams HTTPS streaming capability supports use cases that require streaming data into AWS ( supported by the video stream ARN) for storage and processing – live and on-demand playback via HLS/DASH, and real-time or batch-mode processing for machine learning. The ingestion path is supported by the

Kinesis Video Streams producer SDKs that are available in Java, C/C++, and for Android. The best case live playback latency in this case can range between 3-6 second depending on device capabilities, a limitation that stems from HLS and DASH being fragment based protocols. For adaptive bitrate streaming that would define a decode ladder to adjust to various bandwidths and screen sizes, please refer to the following blog post (

Common use cases for Kinesis Video Streams with WebRTC

Video chat using Kinesis Video Streams with WebRTC                                                                                                                                                                                                          This diagram shows how Video chat using Kinesis Video Streams with WebRTC works.

Telehealth and virtual care in the cloud: COVID-19 pandemic has highlighted the fundamental importance of providing non-COVID-19 related outpatient and inpatient care in clinical settings without exposing patients and health care providers to the virus.

Because WebRTC is a protocol that allows applications to connect to each other in a Peer-to-Peer fashion, there is no intermediary server transferring data between the two parties once the connection is established through the signaling process. Confidential information is never stored in the cloud and patient information is encrypted in transit over the internet.

Real time media streaming in connected cars and vehicle to everything (V2X): V2X is a term that refers to high-bandwidth, low latency, and highly reliable communication between vehicle to vehicle (V2V) and vehicle to infrastructure (V2I) communications. If a vehicle is involved in an accident, the vehicle can live stream the feed on WebRTC while using location awareness so emergency services can call for help as necessary.

There is a new concept emerging called road side units (RSU’s) and when vehicles approach that geographical zone as defined on a map, information is sent to them using the cellular network. RSU cameras can capture video and turn it into a regular webRTC flow that provides a high perspective of the environment such as parked vehicles or road obstacles. Because this transformation does not require transcoding, it has a low processing load and lossless conversion.

In the sharing economy, number anonymity creates a secure, professional barrier in the un-traditional business models at play. With webRTC, ridesharing companies can replace phone masking with the feature of VOIP calling Contextual applications to augment customer experience within websites and applications as a tool for sales enablement.

WebRTC provides a seamless, non-invasive way to connect and collaborate. Massive files can be shared using the webRTC’s data channel with very low latency and the benefit of full encryption between the two end points.
