GB2818的基本对接流程，有用自取👇
- java负责SIP信令的注册交互，推流、拉流鉴权
- 摄像头负责推流、流媒体负责拉流、转码
wvp-GB28181-pro项目 ,如果java对接各种摄像头，这个项目很👍，比较完善，可参考。进去
star支持一波
做到需要播放摄像头视频需要：
概念：
国标协议2818 组成：
sip服务端：
- java实现一般采用
JaiN-SIP- 项目启动时，初始化tpc、udp端口监听，当有接收sip信令时，会触发相关请求事件
流媒体：
- 用作视频、音频流的接入服务的，拉流、推流、解编码服务端；
- 一般用
ZLMediaKit用做流媒体服务器，c++11 性能高、部署较方便- https://gitee.com/xia-chu/ZLMediaKit?_from=gitee_search
配置摄像头接入：
sip注册交互流程：
拉流交互过程：
摄像头返回推流端口：
invite 抓包：
