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

Abstract

The present application discloses a video storage system, computer equipment and storage medium of a national standard camera. The system includes: if a generation discriminator detects that a target national standard camera is connected, obtains the total number of national standard cameras and the CPU usage rate, and if the total number of national standard cameras is less than The first preset number, and the CPU usage rate is less than the preset usage rate, send the thread generation instruction to the thread generator, otherwise send the coroutine generation instruction to the coroutine generator; when the thread generator receives the thread generation instruction, it generates a target Thread; the coroutine generator generates the target coroutine when it receives the coroutine generation instruction. In this application, when the access of the national standard cameras is detected, if the total number of national standard cameras and the CPU usage rate are small, the video stream data is processed by generating threads, otherwise, the video stream data is processed by generating coroutines, so as to avoid the increase of threads causing the CPU The explosive increase of usage rate and the avoidance of video stream data packet loss improve the reliability of video stream data storage.

Description

technical field [0001] The present application relates to the technical field of national standard cameras, in particular to a video storage system, computer equipment and storage medium of a national standard camera. 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 back-end video monitoring platform, and the video monitoring platform will save the video recording data in the disk. The video surveillance platform will access multiple national standard cameras at the same time, and process the video stream data sent by multiple national standard cameras at the same time through multiple threads. Threads that receive and parse video stream data perform CPU-intensive operations, and threads that write data to disk perform IO-intensive operations. CPU-intensive operations take much less time than IO-intensive operations. Switch back and forth between di...

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
