Open WebRTC Toolkit (OWT)


Open WebRTC Toolkit (OWT) is an end to end audio/video communication development toolkit based on WebRTC, which is used to create high-performance, reliable, and scalable real-time communication solutions. OWT is optimized for Intel® Architecture to take full advantage of Intel hardware-acceleration for video encode/decode/scale, and integrated real time video analytics capabilities powered by the OpenVINO™ toolkit. OWT is released under Apache* License 2.0 and it is free for both academic and commercial use.

Intel provides Intel® Collaboration Suite for WebRTC (Intel® CS for WebRTC) as Intel’s distribution of OWT.

OWT is comprised of OWT client SDKs and OWT Server, which are discussed below. 


The client SDKs for OWT builds on top of the W3C standard WebRTC APIs to accelerate development of real-time communications (RTC), including broadcast, peer-to-peer, and conference mode communications.

Five versions of the SDK allow development of real-time communication applications:

  • Android* applications using the client SDK for Android
  • Web applications using the client SDK for JavaScript*
  • iOS* applications using the client SDK for iOS
  • Windows* applications using the client SDK for Windows
  • Linux* applications using the client SDK for Linux


The server for OWT provides an efficient video conference and streaming service that is based on WebRTC. It scales a single WebRTC stream out to many endpoints. At the same time, it enables media analytics capabilities for media streams. It features:

  • High performance VP8, VP9, H.264, and HEVC real-time transcoding on Intel® Core™ and Intel® Xeon® processors, especially those with Intel® Iris® Pro or Intel® HD Graphics
  • Distributed, scalable, and reliable multipoint control unit (MCU) server and analytics server
  • Wide streaming protocols support including WebRTC, RTSP, RTMP, HLS, MPEG-DASH
  • Efficient mixing of HD video streams to save bandwidth and power on mobile devices
  • An intelligent Quality of Service (QoS) control mechanism that adapts to different network environments
  • Customer defined media analytics plugins to perform analytics on streams from MCU
  • The usage scenarios for real-time media analytics including but not limited to movement/object detection
