How to access the liveweb streaming media server through GB28181
1. First download and deploy the liveweb streaming media server. After deployment, enter the configuration center page of the platform.
2. Open the configuration page of the camera or NVR, find the configuration of the GB28181 platform connected to the platform, and set the information in the server configuration center in the second step to the configuration page of the device, and the device can be automatically registered.
Summary:
The GB28181 protocol is that the device actively initiates a registration message to the server and sends a keep-alive message regularly. After the server receives it, it considers the device online. If the keep-alive message is not received within the timeout, it considers the device offline. When the client initiates a request to play a video, the server sends an INVITE request to the specified device, notifying the device to push the video of the specified channel to the server. The server then forwards it to the client, and the user can play it.
