Video storage system of national standard camera, computer equipment and storage medium

Abstract

The invention discloses a video storage system for national standard cameras, computer equipment and a storage medium, and the system comprises a generation discriminator which obtains the total number of national standard cameras and the CPU utilization rate if detecting that a target national standard camera is accessed, and obtains a video storage result if the total number of national standard cameras is smaller than a first preset number and the CPU utilization rate is smaller than a preset utilization rate; sending a thread generation instruction to a thread generator, otherwise, sending a coroutine generation instruction to a coroutine generator; when the thread generator receives the thread generation instruction, generating a target thread; the coroutine generator generates a target coroutine when receiving a coroutine generation instruction. According to the invention, when the access of the national standard cameras is detected, if the total number of the national standard cameras and the usage rate of the CPU are small, the video stream data is processed by generating the thread, otherwise, the video stream data is processed by generating the coroutine, so that explosive increase of the usage rate of the CPU and packet loss of the video stream data caused by increase of the thread are avoided; and the reliability of video stream data storage is improved.

Description

technical field [0001] This application relates to the technical field of national standard cameras, in particular to a video storage system, computer equipment and storage media for national standard cameras. Background technique [0002] In the field of security monitoring, the national standard camera set at the front end will continuously transmit the video recording data to the video monitoring platform at the back end, and the video monitoring platform will save the video recording data in the disk. The video surveillance platform will simultaneously access multiple national standard cameras, and simultaneously process the video stream data sent by multiple national standard cameras through multiple threads. The thread that receives and parses video stream data performs CPU-intensive operations, and the thread that writes data to disk performs IO-intensive operations. CPU-intensive operations take much less time than IO-intensive operations. Switch back and forth betw...

AI Technical Summary

Problems solved by technology

[0003] When the number of cameras connected to the video surveillance platform is too large, the number of threads will also increase, causing the CPU to switch between a large number of threads more frequently, resulting in an explosive increase in CPU usage, and further packet loss of received video stream data occurs. situation, reducing the reliability of storing video stream data
