Mediao Soup Demo协议分析

  • 启动server服务执行
  • 在mediasoup-demo/server目录下执行如下命令
  • DEBUG="mediasoup ERROR WARN" INTERACTIVE="true" node server.js
response:
{"event":"running","targetId":"20795"}
{"event":"running","targetId":"20797"}
{"event":"running","targetId":"20799"}
{"event":"running","targetId":"20801"}

  • 由于测试设备的CPU为4核心所以启动4个worker

  • targetId表示worker进程对应的pid

  • 在mediasoup-demo/app目录下通过

  • gulp live命令启动应用demo服务,首先会使用如下命令创建

  • 创建路由(房间)createRouter会通过信令服务向C++多媒体服务发送如下指令
