Abstract

The embodiment of the invention provides a video data processing method and video data read-write equipment. The video data processing method comprises the following steps: receiving a data read request message, wherein the data read request message comprises initial time of video data to be read; according to the initial time, determining position information of an initial I frame of the video data to be read in a video data storage region; and according to the position information, reading the video data to be read from the video data storage region. According to the embodiment of the invention, by receiving the data read request message comprising the initial time of the video data to be read, the accurate position information of the initial I frame corresponding to the video data to be read in the video data storage region is rapidly determined and the video data to be read is read from the video data storage region according to the position information so as to improve the extraction speed and the working efficiency of the video data.

Description

technical field [0001] The embodiment of the present invention relates to video technology, and in particular to a video data processing method and a video data reading and writing device. Background technique [0002] With the widening of video application fields, the amount of video data is also increasing, and how users can quickly locate the required video data in the massive video data has become an urgent problem to be solved. [0003] In the prior art, video data can usually be divided into multiple video files for storage, and each video file stores a period of video data in the video data, and the video file can include the start time and end time of the video data . When the video data reading and writing device needs to read a certain piece of video data, it needs to first locate which video file the video data to be read is located in. If the start time of the video data to be read is exactly the start time, the video data read-write device can read the video d...
