JT1078转GB28181流程

项目地址：

JT1078转GB28181的流媒体服务器: https://github.com/lkmio/lkm

JT1078转GB28181的信令服务器: https://github.com/lkmio/gb-cms

1. 创建GB28181 UA

调用接口: http://localhost:9000/api/v1/jt/device/add 请求体如下：

{"username": "34020000001400000001","server_id": "34020000002000000001","server_addr": "192.168.31.112:15060","transport": "udp","password": "12345678","register_expires": 3600,"keepalive_interval": 60,"name": "模拟1078设备4","sim_number":"13800138000","manufacturer":"github/lkmio","model":"gb-cms","firmware":"dev"
}

username: 自定义国标设备ID, 唯一键

sim_number: 对应的部标设备sim卡号, 唯一键

2. 添加视频通道

调用接口: http://localhost:9000/api/v1/jt/channel/add 请求体如下：

{"root_id": "34020000001400000001","device_id": "34020000001310000001","name": "视频通道","manufacturer": "github/lkmio","model": "gb-cms","owner": "github/lkmio","channel_number": 1
}

root_id: 创建GB28181 UA接口的username

device_id: 自定义国标视频通道ID

channel_number: 国标视频通道ID对应的1078视频通道号

3. 实现invite钩子

{"sip_port": 5060,"http_port": 9000,"listen_ip": "0.0.0.0","public_ip": "192.168.31.112","sip_id":"34020000002000000001","password":"123456","alive_expires": 180,"mobile_position_interval": 10,"media_server": "0.0.0.0:8080","?auto_close_on_idle": "拉流空闲时, 立即关闭流","auto_close_on_idle": true,"hooks": {"?online": "设备上线通知","online": "","?offline": "设备下线通知","offline": "","?position" : "设备位置通知","position": "","?on_invite": "被邀请, 用于通知1078信令服务器, 向设备下发推流指令","on_invite": "http://localhost:8081/api/v1/jt1078/on_invite","?on_answer": "被查询录像,用于通知1078信令服务器","on_query_record": ""}
}

用户自行实现on_invite钩子, 当上级国标服务器预览部标设备时, 会通过on_invite钩子, 通知部标信令服务器。此时部标信令服务器, 向设备下发请求视频信令，推流到lkm收流端口, lkm再转发到国标流媒体服务器。钩子示例如下:

	t.Run("hook_on_invite", func(t *testing.T) {// 创建http serverrouter := mux.NewRouter()// 示例路由router.HandleFunc("/api/v1/jt1078/on_invite", func(w http.ResponseWriter, r *http.Request) {v := struct {SimNumber     string `json:"sim_number,omitempty"`ChannelNumber string `json:"channel_number,omitempty"`}{}// 读取请求体bytes := make([]byte, 1024)n, err := r.Body.Read(bytes)if n < 1 {panic(err)}err = json.Unmarshal(bytes[:n], &v)if err != nil {panic(err)}fmt.Printf("on_invite sim_number: %s, channel_number: %s\r\n", v.SimNumber, v.ChannelNumber)w.WriteHeader(http.StatusOK)go publish()})server := &http.Server{Addr:         "localhost:8081",Handler:      router,WriteTimeout: 15 * time.Second,ReadTimeout:  15 * time.Second,}err := server.ListenAndServe()if err != nil {panic(err)}})
