Easycvr is cascaded to easygbs through gb28181 protocol. Notes on video channel failure

EasyCVR Support cascading with the national standard platform , After cascading, the platform can pass through GB28181 The agreement obtains the following capabilities ：

1、 Support the national standard GB28181 platform 、 National standard GB28181 IPC And national standards GB28181 NVR The equipment is connected at the same time （ Support GB28181-2011 Version and GB28181-2016 edition ）

2、 Support the national standard GB28181 Device registration and logout , Manage all devices , Access to resources , Manage the resource list

3、 Support the national standard GB28181 Catalog subscription for , Process received subscription notifications

4、 Support the national standard GB28181 Real time video request （ Support UDP、TCP Take the initiative （tcpactive）、TCP passive （tcppassive））

5、 Support the national standard GB28181 PTZ control

EasyCVR Cascading is occasionally encountered during testing EasyGBS The platform cannot play .

Investigation and discovery EasyCVR Software playback is normal , Explain the camera and EasyCVR The platform is normal , Then we can check the configuration information related to cascading , But when we switch the playback protocol to UDP It can be found that the video stream is playing normally .

So in a similar problem , We need to pay attention to two points ：

1. Ensure that the agreements between the parent and child platforms are consistent when docking with the parent platform ;

2. Under the condition that the lower platform plays normally , If it is connected to the superior platform TCP Can't play , You can switch to UDP Try .

In the follow-up to EasyCVR The development of , We will also further optimize the agreement , If you are interested in our optimization process or use method , Welcome to follow us .
