Abstract

The invention provides a video compression method and device, computer equipment and a storage medium, and relates to the technical field of computers. The method comprises the following steps: acquiring an initial quantization parameter corresponding to an Nth frame of image to be compressed; obtaining quality evaluation parameters corresponding to the first M frames of compressed images adjacent to the Nth frame of image; determining a target quantization parameter corresponding to the Nth frame of image according to the initial quantization parameter and the quality evaluation parameter; determining a compression code rate corresponding to the Nth frame of image according to the target quantization parameter; and compressing the Nth frame of image based on the compression code rate. Therefore, according to the quality evaluation parameter of the compressed image frame, the initial quantization parameter of the to-be-compressed image frame is adjusted to determine a more reasonable target quantization parameter, so that a more appropriate compression code rate can be allocated to the to-be-compressed image frame, and the to-be-compressed image frame has better fidelity after being compressed.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a video compression method, device, computer equipment and storage medium. Background technique [0002] With the continuous development of science and technology, video has become a popular way of information transmission. However, due to the large size of video, it is not convenient for transmission and storage. Therefore, video needs to be compressed to save transmission and storage costs. Usually, the amount of video compression, the fidelity of video compression, etc., are mainly affected by the quantization parameter (QuantizationParameter, QP). Therefore, how to determine the quantization parameter so as to assign an appropriate bit rate for each frame of image has become a key research direction. Contents of the invention [0003] The present disclosure aims to solve one of the technical problems in the related art at least to a certain extent. [0004] ...
