Abstract

The invention discloses a file processing method and device, a video playing method and device and an electronic device. The method comprises the following steps: integrating fragmented files into large files in a target video recording jitter scene through a technology of recording'hole information ', optimizing the file storage capability of a system, and breaking through the storage capability limit of the system under massive fragmented files. The technical problem that in the prior art, due to the fact that frequent interruption occurs in the video recording process, large file handles are increased sharply, and then ultimate pressure is caused to a file system is solved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a file processing method and device, a video playing method and device, and an electronic device. Background technique [0002] In the field of video surveillance, especially in the security industry, video data is collected in real time, such as video files. The collected data has continuity on the time axis, and the continuous data will grow infinitely with time. We call this type of data "streaming data". For streaming data, it will be divided according to time intervals, such as interval One hour is divided into one large file, and each large file is also continuous on the time axis. [0003] This streaming data file is continuous by default in scenarios such as video query, video playback, and video forwarding. If an interruption occurs, it will be switched to a different file by default, so that it can be fed back to the application layer for interruption through file attr...
