Background
With its unique unified status in the security streaming media industry, the GB28181 protocol has been used in various security projects. Projects such as Xueliang Engineering, kindergarten monitoring, smart construction sites, logistics monitoring, etc. currently require access to security cameras or platforms for live broadcast and playback. The GB28181 protocol is a national recommended standard. Currently, security cameras, NVRs, and monitoring platforms from almost all manufacturers support this protocol. This makes it convenient for us to obtain video streams from various manufacturers' devices through the GB28181 protocol without having to tediously connect each device. SDK.
GB28181 obtains video streaming RTMP, HLS, RTSP, HTTP-FLV for live broadcast
The video stream obtained by GB28181 protocol is an RTP packet encapsulated by PS. PS packets cannot be directly Play directly using web or player. The obtained PS stream needs to be converted into an ES stream, and then packaged and provided in RTMP, HLS, RTSP, and HTTP-FLV formats for live stream distribution. In this way, the security camera can be streamed through the GB28181 protocol into an Internet live broadcast method that can be live broadcast, played back, and controlled on the Web, mobile phones, WeChat, and clients.
The liveweb streaming media platform is implemented according to this design method, and at the same time provides a secondary developed http interface for users to integrate.
