EasyPusher安卓Android手机直播推送之RTSP流媒体协议流程
EasyPusher移动端推送同我们平时用的RTSP直播推送流程一样，都是采用标准RTSP/RTP推送流程：ANNOUNCE->SETUP->PLAY->RTP/RTCP->TEARDOWN(或者直接直接断开推送连接)，流程图如下：
我们贴一段EasyPusher 安卓与EasyDarwin流媒体服务器之间的交互报文：

如上流程，服务器端为：192.168.1.101:554，推送端：192.168.1.107，EasyPusher采用的是RTP over TCP的方式进行推送，所以此过程在公网手机视频直播、移动4G直播、单兵直播项目中都同样可用！
