Abstract

The invention relates to a video encoding and decoding method, device and system and electronic equipment, which are used for solving the technical problem of low efficiency of decoding high-resolution video data by using the prior art. The method comprises the steps of obtaining feature information of original image data; If the feature information of the original image data is greater than the preset feature threshold value, controlling a graphics processing unit (GPU) to execute a first compression operation on the original image data to obtain intermediate compressed data, the graphics processing unit (GPU) supporting identification and loading of the intermediate compressed data; And executing a second compression operation on the intermediate compressed data to obtain target video coded data.

Description

technical field [0001] The present disclosure relates to the field of video technology, and in particular, to a video encoding and decoding method, device, system and electronic equipment. Background technique [0002] As video technology tends to develop in the direction of high resolution and high frame rate, the resolution of pictures and video data is getting higher and higher. Correspondingly, the requirements for system hardware configuration are also getting higher and higher. In the existing technology, the international video codec standard H.265 can realize high-efficiency coding, can support 4K (4096×2160) and 8K (8192×4320) ultra-high-definition video at the same time, and can transmit higher-quality network under limited bandwidth Video, mobile devices such as smartphones and tablets can directly play high-resolution videos online after decoding. However, when a graphics processor GPU with a certain codec capability decodes high-resolution video data, if the re...
