In the remote video surveillance system, the original video stream obtained by the camera needs to be compressed before transmission, and FFmpeg can compress the original video into a H264 format video stream, which is a widely used high-precision video recording, compression and publishing format, So use FFmpeg to achieve.
It directly supports network video transmission and network management, making the monitoring range reach an unprecedented breadth. The embedded network video server has powerful functions such as video encoding processing, network communication, system control, etc. The system directly converts the analog video signal output by the camera into a video stream through a built-in embedded video encoder, and transmits it through a computer network. With the development of video coding and decoding technology, computer network technology, digital signal processing technology and embedded systems, remote video surveillance systems based on embedded network video servers have begun to emerge in the market.
