Abstract

The invention relates to a video processing method, device and equipment and a storage medium, and belongs to the technical field of multimedia. According to some embodiments of the invention, the method comprises the steps of: preprocessing and encoding an original video; obtaining a compression distortion parameter of the video according to the coded video; adjusting the pre-processing parameters according to the compression distortion parameters; and considering the compression distortion after the video coding when the pre-processing parameters are adjusted, so that the accuracy of the adjusted pre-processing parameters is remarkably improved, the device performs pre-processing by applying the adjusted pre-processing parameters, the compression distortion of the video after encoding can be reduced, the quality of the video is improved, and the video pre-processing performance of the device is optimized.

Description

technical field [0001] The present disclosure relates to the field of multimedia technologies, and in particular to a video processing method, device, equipment and storage medium. Background technique [0002] Video pre-processing refers to operations performed on video at the pixel level before it is encoded. By pre-processing the video and then decoding the video, it helps to reduce the compression distortion of the video after encoding. In the related art, the filter coefficient of the filter is manually preset, and when the original video is obtained, the filter performs a low-pass filtering operation on the original video according to the manually set filter coefficient, thereby realizing video pre-processing. After the filter obtains the filtered video, the filtered video is input to the video encoder. The video encoder encodes the filtered video to obtain the encoded video. When the above method is adopted, the compression distortion of the encoded video is relati...
