Multi-channel video storage method and system

Abstract

The invention provides a multi-channel video storage method and system, and the method comprises the steps: receiving, splicing and caching video data transmitted by each video collection channel in real time for each video collection channel; correspondingly judging whether the data size of each path of cached video data reaches D bytes or not in real time, wherein video data segments with the length of the front D bytes are cut for each path of video data with the data size reaching D bytes, and the video data segments are written into a shared memory after channel identifiers are marked; and calculating the size of the remaining available space of the shared memory in real time, reading the data in the shared memory based on the calculated size of the remaining available space, addressing the storage hard disk for each read video data segment according to the marked channel identifier, and then writing in the corresponding storage hard disk. According to the method, the number of hard disk operation times is reduced, the requirement for temporary memory storage space is lowered, and the rationality of hard disk space utilization is improved.

Description

technical field [0001] The invention relates to the field of servers, in particular to a multi-channel video storage method and system. Background technique [0002] With the development of the network, the scene of video information processing in the network is becoming more and more common. With the increase of bandwidth resources, more and more application scenarios require a large number of high-concurrency video solutions. There are more and more application scenarios where multiple channels of video are stored simultaneously. [0003] At present, most multi-channel video storage application scenarios use multi-thread processing and are equipped with multiple hard disks. Each channel of video receives video data separately and then stores it in the corresponding hard disk. There are often the following problems: [0004] 1. Each channel of video is stored separately, that is, each time the data sent by a front-end video acquisition device is received, a data hard disk...

AI Technical Summary

Problems solved by technology

It is easy to cause too many hard disk operations and consume more program running time

[0005] 2. Each video processing thread (used for video acquisition and receiving operations) often opens up a temporary memory storage space for video data separately. When there are too many video threads, the temporary memory storage space is often required too much

[0006] 3. The reading and storage of data cannot perform system management on the hard disk that stores the data, which may easily cause uneven progress in the use of the hard disk, and the situation that a certain hard disk space is exhausted while other related hard disks are used at a low level may easily lead to hard disk space. Unreasonable use
