Embodiment Construction

[0023] figure 1 is a schematic flowchart of a method for recording video using multiple compression methods according to an embodiment of the present invention. like figure 1 As shown, methods for recording video with various compression methods include:

[0024] S1, receiving a recording instruction, creating a recording file in the memory, collecting video data, and buffering the collected video data into the RAM; wherein, the video data is the original image data captured by the camera sensor;

[0025] S2. When the video data in the random access memory reaches a preset value, continue to collect video data, wherein the remaining storage space of the memory is detected, and when the remaining storage space of the memory is less than the preset value, traverse all The video data in the random access memory, the video data in the random memory including the moving target and the data content not containing the moving target are respectively compressed in different compressi...

Abstract

The invention provides a method for recording videos in multiple compression modes, and relates to the field of video recording. The method comprises the following steps: S1, receiving a recording instruction, creating a recording file in a memory, collecting video data, and caching the collected video data in a random memory, wherein the video data are original image data grabbed by a camera sensor; S2, when the video data in the random memory reach a preset value, continuing to collect the video data, detecting a residual storage space of the memory, when the residual storage space of the memory is smaller than the preset value, traversing the video data in the random memory, and performing video compression on the data contents containing moving targets and not containing the moving targets in the video data in the random memory; and S3, writing the compressed video data in the recording file.

Description

technical field [0001] The invention relates to the field of video recording, in particular to a method for recording video using multiple compression methods. Background technique [0002] At present, video surveillance systems have been involved in all walks of life in society, such as traffic intersections, supermarkets, banks, stations, and residential quarters. Many monitoring equipment, such as Olympic venues, People's Square, World Expo site, etc. At the same time, due to the emergence of massive surveillance video data, the traditional video surveillance system that relies entirely on manual monitoring can no longer meet the needs. People need more intelligent, automated, and autonomous video surveillance systems. Therefore, intelligent video surveillance systems have become an upgrade The main development direction of video surveillance system performance. [0003] There are more and more electronic products with recording function on the market, but most of these...
