Problems solved by technology

[0005] 3) When the file system is full, it is necessary to delete the old video files. The traditional file system is inefficient in the case of writing while deleting, and causes a large number of fragments in the video file
[0006] 4) Storage based on the traditional file system is not convenient for second-level retrieval of video data

Embodiment Construction

[0022] A method for storing streaming data in a video surveillance application of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] as attached figure 1 As shown, an object-oriented method for storing streaming data in video surveillance applications, using an object-oriented approach to develop automated test scripts. When writing test scripts, first define all automation control objects, and then use these automation control objects as templates to create class libraries, and then initialize these class libraries to obtain instantiated automation control objects. So far, the basis of automated test scripts Then the construction is completed, and the writing of the top-level execution script becomes very simple, just list the methods of these automation control objects according to the test process. Its specific stored procedure is:

[0024] 1) Before video storage, the raw device storage pool is first initialize...

Abstract

The invention provides a stream data storage method in video monitoring application. Video data frame is used as unit to perform read and write on a disk raw device, file-based management of video data does not rely on a traditional file system any more, the length of the frame of data is recorded at the starting and ending positions of each frame of data, the deflecting position of the first frame of data of the first second is recorded in a database due to the fact that each second may contain multiple frames of data, and the subsequent frames of data can be sequentially calculated and read according to the frame length recorded on the disk. Compared with the prior art, the stream data storage method has the advantages that the method is high in practicality and easy to popularize, the problem of fragmentization of storage based on the file system is solved, and second-level retrieval of video data can be supported.

Description

technical field [0001] The invention relates to the technical field of computer data storage, in particular to a method for storing streaming data in video surveillance applications. Background technique [0002] In the field of video surveillance, the file system is usually used to store video files, but when using the traditional file system, there are the following disadvantages: [0003] 1) Video files are usually hundreds of megabytes of large files. The traditional file system is an application that takes into account the reading and writing of small files, and usually cannot provide the best performance support for large files. [0004] 2) In the current video surveillance application, there are usually dozens or hundreds of cameras on the front end, and each camera on the back end corresponds to a video file. The traditional file system is inefficient in the case of multi-channel concurrent writing. [0005] 3) When the file system is full, the old video fil...
