WVP GB28181服务器取视频流
看最近的访问搜索关键字，大部分都是通过WVP-GB28181关键字搜索过来的，原来调到一半，就去干别的事情了，趁着年前比较空闲，重新捡起来，发现还比较顺利的调通了取流，记录下过程。
pjsip客户端注册到wvp sip服务器的default.config配置文件。
# This is a comment in the config file. #--id sip:44010200491110000001@47.105.47.160:5061;transport=tcp #--registrar sip:47.105.47.160:5061;transport=tcp #--realm 3402000000 --id sip:41010500002000000002@4101050000 --registrar sip:4101050000 --proxy=sip:192.168.16.213:8116 --realm 4101050000 --username 41010500002000000002 --password 12345678 --local-port=5066 #--auto-loop --clock-rate 16000 --ptime 20 #--null-audio #--ip-addr=192.168.16.99 #log-config --log-level=6 #--log-file=log/siplog --auto-answer 200 #video --video --vcapture-dev 0 #webrtc echo --ec-opt=3 #--stereo --ec-tail=75 #register --reg-timeout=120
WVP的配置文件错误，导致取流一直报“未找到可用的zlm”，主要是application.yml配置文件中zlm的id配置不正确。
media:
#media-server-Id
id: f5pIoX4tqRzE7TI0
media-server-Id是config.ini文件中的mediaServerId
[general] addMuteAudio=1 check_nvidia_dev=1 continue_push_ms=15000 enableVhost=0 enable_audio=1 enable_ffmpeg_log=0 flowThreshold=1024 fmp4_demand=0 hls_demand=0 maxStreamWaitMS=15000 mediaServerId=f5pIoX4tqRzE7TI0
取流报500错误：
2024-02-06 17:17:29.103 ERROR --- GlobalExceptionHandler : [鍏ㄥ眬寮傚父]锛? java.lang.NullPointerException: null at com.genersoft.iot.vmp.service.impl.PlayServiceImpl.play(PlayServiceImpl.java:119) at com.genersoft.iot.vmp.vmanager.gb28181.play.PlayController.play(PlayController.java:124) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)
修改PlayServiceImpl.java:119行，重新编译：
修改前：
if (device.getStreamMode().equalsIgnoreCase("TCP-ACTIVE") && !mediaServerItem.isRtpEnable()) {
logger.warn("[点播] 单端口收流时不支持TCP主动方式收流 deviceId: {},channelId:{}", deviceId, channelId);
throw new ControllerException(ErrorCode.ERROR100.getCode(), "单端口收流时不支持TCP主动方式收流");
}
修改后：
if (device != null && device.getStreamMode() != null && device.getStreamMode().equalsIgnoreCase("TCP-ACTIVE") && !mediaServerItem.isRtpEnable()) {
logger.warn("[点播] 单端口收流时不支持TCP主动方式收流 deviceId: {},channelId:{}", deviceId, channelId);
throw new ControllerException(ErrorCode.ERROR100.getCode(), "单端口收流时不支持TCP主动方式收流");
}
终于是看到视频了，下一步，继续分析源代码。
从ZLM查看到的日志：WVP向zlm申请了一个rtp的端口，然后将这个端口转发给了国标摄像头，然后zlm接收到推流后，通知到WVP，界面显示刷新。

结束的时候关闭rtp端口：
