Abstract

The invention provides a video file processing method and a device, and relates to the technical field of information processing, and the method comprises the steps: determining idle data blocks in adisk of a file system according to file attributes stored in a memory; determining the number of data blocks required by the to-be-stored video file according to the size of the to-be-stored video file; determining a target data block from the idle data blocks according to the number of data blocks required by the to-be-stored video file; and storing the to-be-stored video file into the target data block, and updating the file attributes recorded by the file index unit of the block group where the target data block is located and the file attributes loaded from the file index unit of the blockgroup where the target data block is located in the memory. A disk of the file system is divided into a plurality of block groups, and each block group comprises an index area and a data area, so that segmented storage of the index area and the data area of the file system is realized, the access performance of the data area in the whole file system is prevented from being influenced by damage ofa certain index area, and the use performance of the file system is effectively improved.

Description

[0001] This application claims the priority of the Chinese patent application submitted to the China Patent Office on June 06, 2019, with the application number CN201910494901.3 and the application date titled "Video File Processing Method and Device", the entire contents of which are incorporated herein by reference Applying. technical field [0002] The technical field of information processing of the present application, in particular, relates to a video file processing method and device. Background technique [0003] In recent years, video surveillance technology has developed rapidly. In the process of video surveillance, massive data is usually generated and a large amount of storage resources are required to store video data. Therefore, it is particularly important to use an efficient and reliable file system for massive data management. . At present, in order to meet different application scenarios, a variety of file systems have emerged. [0004] The index area an...
