How to use the national standard streaming media server to view the video stream of the surveillance camera? How to correctly use UDP and TCP protocols?

The friends who have used the GB streaming media server should know ,GB28181 The agreement was put forward by the Ministry of public security , It can connect with the network system of the Ministry of public security , It brings great convenience to security , Our national standard streaming media server supports integrated access to its own platform , You can also record video .

Using GB streaming media server will have many secondary development possibilities , Because we will provide rich secondary development interface . Recently, many users use https Access to GB streaming media server , It is a kind of practical live video monitoring .

There was a developer who wanted to test , Haikang's wired camera is installed in its own field environment , adopt 4g turn wifi To connect , After uploading the video to the platform , The longest time to open a video is 10 Minutes or so to display , Most of the time 3~4 Minutes to come out , For this reason, the developer found our technical support , Ask for help .

This is the most common delay in live video broadcasting , Our technical support is to suggest the developer to reduce the bit rate and resolution for testing , You can debug the resolution and bit rate in the address shown below ：

Normal mode , The video stream in the streaming media server is to go udp Protocol to transmit ,UDP The characteristic of the protocol is that there is no need to establish a connection before transmitting data , It also avoids subsequent disconnection , Do not reorder packets that arrive out of order . After modifying the resolution and bit rate , Put our streaming media server UDP The transmission protocol is changed to TCP Transfer protocol , It can be played normally .
