Abstract

Embodiments of the present application provide a video decoding method, encoding method, device, medium and electronic equipment. The video decoding method includes: acquiring encoded data corresponding to a video frame to be decoded, wherein the encoded data contains an encoding result of a target syntax element, and the target syntax element is used to indicate a scanning mode of a coding block of the video frame; based on the target Performing a first decoding process on the encoding result of the syntax element to obtain the value of the target syntax element; determining the scanning mode according to the value of the target syntax element; performing a second decoding process on the encoded data based on the scanning mode. The technical solutions of the embodiments of the present application can select the most suitable scanning mode for encoding and decoding processing according to the coefficient distribution characteristics of the video frame coding block, which improves the coding efficiency and decoding efficiency of the video frame coding block.

Description

technical field [0001] The present application relates to the field of computer and communication technologies, and in particular, to a video decoding method, encoding method, device, medium and electronic equipment. Background technique [0002] In video coding standards, coefficient coding means that the entire coding block is coded one by one in a certain scanning mode, and the scanning mode determines the range of coefficient coding. However, none of the scanning methods proposed in the related art can effectively encode coding blocks with various coefficient distribution characteristics, which will affect the coding efficiency and decoding efficiency of the coding blocks. Contents of the invention [0003] Embodiments of the present application provide a video decoding method, encoding method, device, medium, and electronic equipment, and then at least to a certain extent, can select the most suitable scanning method for encoding and decoding processing according to t...
