Problems solved by technology

[0002] The existing technology is to directly write small video files (less than 4MB) into the storage system. When many cameras are connected, the concurrency will lead to a large number of random IO, which puts huge IO pressure on the mechanical disk.
If the position of the I frame is not recorded, the playback video positioning is not timely, and redundant videos are downloaded, which wastes network bandwidth and causes the video to freeze and not smooth

Abstract

The invention relates to a method for realizing high concurrency and quick playback of Internet video monitoring cloud storage. The method comprises the following steps of: A, recording a video and transmitting the video to a video server; b, processing and storing, by the video server, the video recorded in the step A; and C, quickly playing back the processed video. The method has the advantagesthat a plurality of small video files are combined into a large video recording file, random IO is changed into sequential IO, the number of files is reduced, the IO pressure of a storage system is greatly reduced, and the video server can improve the video concurrent write-in capacity by nearly 5-10 times; according to the I-frame index file, the video position of video playback can be quickly positioned, the video playing waiting time of a user is greatly shortened, and the user experience is improved.

Description

technical field [0001] The invention relates to a method for realizing high concurrency and fast playback of video surveillance cloud storage, which is used in the field of high concurrency video processing by a video server system when accessing a large number of cameras. Background technique [0002] The existing technology is to directly write small video files (less than 4MB) into the storage system. When many cameras are connected, the concurrency will lead to a large amount of random IO, which puts huge IO pressure on the mechanical disk. If the position of the I frame is not recorded, the playback video location is not timely, and redundant videos are downloaded, which wastes network bandwidth and causes the video to freeze and not smooth. Contents of the invention [0003] In order to overcome the defects of the prior art, the present invention provides a method for realizing high concurrency and fast playback of video surveillance cloud storage in an Internet envi...
