摘　　要：在Flash盛行的时代,RTMP是实现直播的主要方式,但随着Flash被淘汰后,RTMP也逐渐退出舞台。目前,HLS是一种主流方式,但采用HLS方式的直播通常会存在较大的延时。WebRTC可以完美契合现代浏览器,同时直播流的延时极低,能很好地解决RTMP及HLS面临的困境。因此,可以使用WebRTC来实现一个低延时的直播系统,同时以SFU网络模型的Janus为系统的流媒体服务器,实现音视频推流拉流播放、聊天室等功能。In the era of Flash,RTMP is the main way to realize live broadcast,but with the elimination of Flash,RTMP has gradually withdrawn from the stage.At present,HLS is a mainstream method,but live broadcast using HLS usually has a large delay.WebRTC can perfectly fit modern browsers,and the delay of live broadcast is extremely low,which can solve the dilemma faced by RTMP and HLS.Therefore,WebRTC can be used to implement a low-latency live broadcast system.At the same time,the Janus of the SFU network model is used as the streaming media server of the system to realize audio&video streaming and streaming playback,chat rooms and other functions.
