基于WebRTC技术的多人视频通信系统

WebRTC technology gives browsers the ability of real-time audio and video communications. Developers can easily use the API provided by WebRTC, establish the peer-to-peer connection and realize the media communications. Currently, a lot of browsers have supported WebRTC technology. Based on the WebRTC technology, this paper puts forward a complete solution of mutil-video communications, that the video stream network is composed of many single p2p connections automatically. We use WebSocket to complete the full-duplex communication between the server and client. This system will decrease the cost of the servers' capacity and bandwidth than the traditional one, which needs the server to deal with the mixing of multi-video data.
