Embodiment Construction

[0043] Exemplary embodiments of the present invention are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present invention to facilitate understanding, and they should be regarded as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

[0044] The existing video storage method utilizes file systems such as disk storage to store video files. For long-time video files, large storage resources are required to save them; and when they are transmitted in the network, the transmission speed is slow due to the large video files.

[0045] like figure 1 As shown, the video live broadcast mainly includes the foll...

Abstract

The invention discloses a video storage method and device and a video generation method and device, and relates to the technical field of computers. One specific embodiment of the method comprises thefollowing steps: analyzing video content of a video stream to obtain a content change result; extracting a change video from the video stream based on the content change result, and storing the change video; and extracting a non-change video from the video stream based on the content change result, and performing slice storage on the non-change video. According to the embodiment, the volume occupied for storing the video file is reduced, and meanwhile, the data redundancy is reduced; more video files can be stored in a limited volume; and the playing delay during live video broadcasting is reduced or eliminated.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for storing video and a method and device for generating video. Background technique [0002] Video surveillance is an indispensable part of our daily life. At the same time, many cameras are recording the world or people's lives every day, such as traffic monitoring, station monitoring or other public places. These real-time images (ie video files) are also To archive storage, the storage place is a file system such as disk storage. Among them, the disk memory uses the disk as the storage medium. It is an auxiliary memory that uses magnetic recording technology to store data on a rotating disc coated with a magnetic recording medium. It has large storage capacity, high data transmission rate, and long-term storage of data. Save and other features. [0003] For the scene of live video broadcast, the video source (that is, the anchor) needs to push ...
