Video coding method and device, computer equipment and storage medium

Abstract

The invention relates to a video coding method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a current coding block, wherein the current coding block is an uncoded coding block in a video sequence; obtaining a coding mark, wherein the coding mark is a pre-judgment mark generated by coding the previous coding block; if the coding mark is a first mark, coding the current coding block according to a first coding mode; if the coding mark is a second mark, coding the current coding block according to a second coding mode; if the coding of the current coding block is completed, obtaining corresponding coding data. The coding strategy of the current coding block is determined based on the pre-judgment mark generated by the previous coding block, namely the corresponding coding strategies are selected according to different types of coding blocks, so that the coding compression performance is improved, the coding time is shortened, and the coding efficiency is improved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a video coding method, device, computer equipment and storage medium. Background technique [0002] The so-called video encoding method refers to the method of converting the original video format file into another video format file through compression technology. The most important codec standards in video stream transmission are H.261, H.263, H.264, H.265 / HEVC (High Efficiency Video Coding), H.266 / VVC (Versatile Video Coding, multi-functional video encoding). [0003] Many encoding tools in H.266 / VVC usually use SCC encoding tools to encode video sequences. Video sequences are composed of several frames of images. One frame of images can be divided into several non-overlapping encoding blocks. When the video sequence contains SCC at the same time (Screen Content Coding, screen content video) fragments and non-SCC fragments, the prior art uses the same coding s...

Problems solved by technology

[0003] Many encoding tools in H.266 / VVC usually use SCC encoding tools to encode video sequences. Video sequences are composed of several frames of images. One frame of images can be divided into several non-overlapping encoding blocks. When the video sequence contains SCC at the same time (Screen Content Coding, screen content video) fragments and non-SCC fragments, the prior art uses the same coding strategy to compress the SCC fragments and non-SCC fragments in the video sequence through the SCC coding tool, and it is impossible to adopt different coding strategies for different types of fragments. The encoding strategy of SCC encoding tool can greatly improve the compression performance of SCC segments, but the compression performance improvement of non-SCC segments is small and time-consuming, which prolongs the encoding time and reduces the video encoding efficiency.
