Video coding method and device and electronic equipment

Abstract

The invention provides a video coding method and device and electronic equipment. A video to be coded is divided into a plurality of frame sequences; for each frame sequence, determining a target coding parameter of the current frame sequence based on a plurality of preset initial coding parameters and a parameter determination principle; wherein the parameter determination principle comprises that the total quality parameter of the to-be-coded video meets a preset quality parameter threshold value, and the total code rate of the to-be-coded video is the lowest; and coding the video to be coded through the target coding parameter of each frame sequence. In the mode, the frame sequence is used as an analysis unit, and the target coding parameter of the current frame sequence is determined for each frame sequence under the conditions that the total quality parameter of the video to be coded meets the preset quality parameter threshold and the total code rate of the video to be coded is the lowest, so that a lower code rate can be obtained on the premise of ensuring the video quality, and the coding efficiency is improved. And the coding efficiency of video coding is improved.

Description

technical field [0001] The present invention relates to the technical field of video coding, in particular to a video coding method, device and electronic equipment. Background technique [0002] Video coding is to encode video signals through specific compression technology to realize video format conversion, thereby reducing the amount of video data and signal bandwidth, which is conducive to video storage and transmission. Video encoding can reduce the bit rate of the video, thereby affecting the quality of the video. Generally, the lower the bitrate of the video, the lower the quality of the video. [0003] During the video encoding process, the bit rate of the video can be controlled by CRF (Constant Rate Factor, constant rate factor). CRF is a code rate control method. Usually, according to the service to which the video belongs, the video quality to be achieved by video coding can be determined. Based on the video quality, the CRF value used for video coding is dete...

Problems solved by technology

CRF is a code rate control method. Usually, according to the service to which the video belongs, the video quality to be achieved by video coding can be determined. Based on the video quality, the CRF value used for video coding is determined, and then the video is globally implemented based on the CRF value. encoding, which leads to low encoding efficiency of video encoding
