Video compression method, device and equipment and computer readable storage medium

Abstract

The invention discloses a video compression method, device and equipmentand a computer readable storage medium. The method comprises the steps of obtaining a current frame of to-be-compressed image; comparing the current frame of to-be-compressed image with the previous frame of to-be-compressed image to obtain change image block data, wherein the change image block data comprises target image blocks, which are different from the previous frame of to-be-compressed image, in the current frame of to-be-compressed image and image coordinates corresponding to the target image blocks; and performing image compression on the change image block data to obtain an image block compression file corresponding to the current frame of to-be-compressed image. According to the invention, the current frame of to-be-compressed image is compared with the previous frame of to-be-compressed image to obtain the data of the change image blocks, and the image blocks needing to be compressed are determined by using the inter-frame compression technology, so that the data volume needing to be compressed is reduced, the video compression ratio is greatly improved, the network transmission data volume is reduced, the image transmission time is shortened, and the remote display effect is ensured.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a video compression method, device, equipment and computer-readable storage medium. Background technique [0002] BMC is the base board management control chip on the server. It is mainly responsible for monitoring the temperature, voltage, fan, power supply and other information of the server's system hardware, and making corresponding adjustments to ensure that the system is in a healthy state. At the same time, BMC provides a remote access network interface for the server, and the client terminal remotely accesses the server through the network interface of the BMC, and realizes the desktop display of the server on the client terminal, thereby enabling KVM (Keyboard Video Mouse, keyboard, video and mouse) video transmission ; That is to say, the BMC can transmit the video stream of the server to the client terminal for display. [0003] In the prior art, since the v...

Problems solved by technology

[0003] In the prior art, since the video stream is composed of images frame by frame, video compression is often achieved by compressing each frame of image to reduce the amount of network transmission data; and video compression for compressing each frame of image In this way, the amount of data required for network transmission is still large, resulting in a long image transmission time, which is not conducive to remote display
