海康摄像头配置

 

代码解析

Wvp 启动流程

ZLMRunner

默认zlm初始化：

1. 修改zlm【hook】配置
2. 获取zlm配置
3. 更新zlm信息

在线事件监听器，监听到离线后，修改设备离在线状态。 设备在线有两个来源：*               1、设备主动注销，发送注销指令*               2、设备未知原因离线，心跳超时

ZLMStatusEventListener

启动sipServer 监听信令消息

SipLayer

监听sip信令（udp）

 Tcp

 处理接收IPCamera发来的SIP协议请求消息

SIPRequestProcessorParent

类型包括：

Request

message、info、 ack、bye、cancel、invite、 notify、register、subscribe

 

 

Response

bye、cancel、invite、register

 

设备能力接口，用于定义设备的控制、查询能力（sip指令）

SIPCommander

查询设备状态

deviceStatusQuery

查询设备信息

deviceInfoQuery

查询目录列表

catalogQuery

请求预览视频流

playStreamCmd

平台能力接口

SIPCommanderFroPlatform

事件推送

事件通知推送器，支持推送在线事件、离线事件

EventPublisher

事件监听：报警事件监听、catalog事件、录像查询结束时间

SIPProcessorObserver

 

Zlm回调接口

ZLMHttpHookListener

针对 ZLMediaServer的hook事件监听

服务器定时上报

on_server_keepalive

流量统计事件

on_flow_report

访问http文件服务器上hls之外的文件时触发

on_http_access

播放器鉴权事件，rtsp/rtmp/http-flv/ws-flv/hls的播放都将触发此鉴权事件

on_play

rtsp/rtmp/rtp推流鉴权事件

on_publish

rtsp专用的鉴权事件，先触发on_rtsp_realm事件然后才会触发on_rtsp_auth事件

on_rtsp_realm

该rtsp流是否开启rtsp专用方式的鉴权事件，开启后才会触发on_rtsp_auth事件。需要指出的是rtsp也支持url参数鉴权，它支持两种方式鉴权

on_rtsp_auth

rtsp/rtmp流注册或注销时触发此事件；此事件对回复不敏感

on_stream_changed

流无人观看时事件，用户可以通过此事件选择是否关闭无人看的流

on_stream_none_reader

流未找到事件，用户可以在此事件触发时，立即去拉流，这样可以实现按需拉流；此事件对回复不敏感

on_stream_not_found

服务器启动事件，可以用于监听服务器崩溃重启；此事件对回复不敏感

on_server_started
