CDNBye dashjs-p2p-engine implements WebRTC datachannel to scale live/vod video streaming by peer-to-peer network using bittorrent-like protocol. The forming peer network can be layed over other CDNs or on top of the origin server. Powered by dash.js, it can play MPEG-dash on PC and mobile.


  • WebRTC data channels for lightweight peer-to-peer communication with no plugins
  • Support live and VOD streams over MPEG-dash protocol
  • Very easy to integrate with an existing dash.js project
  • Seamlessly fallback to normal server usage if a browser doesn't support WebRTC
  • Compatible with all CDNs, agnostic to DRM and video codecs. No service side changes required.
  • Efficient scheduling policies to enhance the performance of P2P streaming
  • Use IP database to group up peers by ISP and regions

Getting Started

Put the quick-start.html in your web page, run it. Wait for a few seconds,then open the same page from another browser. Now you have a direct P2P connection between two browsers without plugin! The first web peer will serve as a seed, if no one else in the same channel.

Browser Support

WebRTC has already been incorporated into the HTML5 standard and it is broadly deployed in modern browsers. The compatibility of CDNBye depends on the browser support of WebRTC and dash.js. Please note that iOS Safari "Mobile" does not support the MediaSource API.

Compatibility Chrome Firefox macOS Safari Android Wechat/QQ Opera Edge IE iOS Safari
