Video processing method and device and storage medium

Abstract

The invention provides a video processing method and device and a storage medium. The method comprises the following steps: encoding and decoding an original video to obtain a mixed resolution video, wherein the mixed resolution video comprises a first resolution frame and a second resolution frame corresponding to a key frame, and further comprises a third resolution frame corresponding to a non-key frame, wherein the resolution of the first resolution frame is higher than the resolution of the second resolution frame and the resolution of the third resolution frame; and according to the first resolution frame and the second resolution frame, amplifying a third resolution frame corresponding to the non-key frame and outputting an amplified video, wherein the amplified video comprises the first resolution frame corresponding to the key frame and an amplified target frame corresponding to the non-key frame. According to the scheme, for the non-key frame, the low-resolution frame is obtained only by encoding and decoding, then the low-resolution frame is amplified according to the information of the key frame, the amplified high-resolution video is obtained with less code stream, and the bandwidth pressure of video transmission is reduced.

Description

technical field [0001] The present application relates to video processing technology, for example, to a video processing method, device and storage medium. Background technique [0002] In today's information age, the proportion of video information is getting higher and higher, and the amount of video data is increasing. Video transmission and compression are particularly important. Although the codec technology continues to develop, in areas with poor conditions, such as mountainous areas or other areas with harsh environments, due to insufficient base stations and insufficient broadband resources, video information may be lost and transmission delays may be large. The entire video is greatly compressed, and the decoded video has low resolution, poor subjective and objective quality, and poor amplification, which seriously affects the viewing experience. At present, there is no effective video processing method, which can not only reduce the resources occupied by video d...

AI Technical Summary

Problems solved by technology

Although the codec technology continues to develop, in areas with poor conditions, such as mountainous areas or other areas with harsh environments, due to insufficient base stations and insufficient broadband resources, video information may be lost and transmission delays may be large. Significantly compress the entire video, the decoded video has low resolution, poor subjective and objective quality and magnification effect, which seriously affects the viewing experience

At present, there is no effective video processing method, which can not only reduce the resources occupied by video data transmission, but also decode and obtain high-quality video in harsh environments, insufficient resources, or traffic restriction scenarios.
