Abstract

The invention provides a video coding method, which comprises the following steps: receiving a video image frame, and obtaining at least one tree coding unit of the video image frame; dividing the tree-shaped coding units according to different video prediction unit division rules so as to obtain video prediction units with different sizes of the tree-shaped coding units; performing primary selection on the predicted brightness directions of intra-frame prediction of the video prediction units of different sizes to obtain the set number of intra-frame prediction primary selection brightness directions of the video prediction units of different sizes; setting an intra-frame prediction optimal brightness direction of a video prediction unit of the current size; selecting predicted chrominance directions of intra-frame prediction of video prediction units of different sizes to obtain an intra-frame prediction optimal chrominance direction of the video prediction units of different sizes;and performing intra-frame prediction coding on the current video image frame according to the intra-frame prediction optimal brightness direction and the intra-frame prediction optimal chromaticity direction.

Description

technical field [0001] The present invention relates to the field of video coding, in particular to a video coding method, a video coding device, electronic equipment and a storage medium. Background technique [0002] The development trend of future video is high definition, high frame rate and high compression rate. The popular H.264 compression method has certain limitations in principle and cannot meet the needs of the future. Therefore, HEVC (High Efficiency Video Coding, efficient Video coding) coding protocol came into being. [0003] Such as figure 1 as shown, figure 1 It is a standard HEVC coding frame structure. A frame of image is sent to the encoder, after intra-frame prediction or inter-frame prediction, the predicted value is obtained, and the predicted value is subtracted from the input data to obtain the residual, and then DCT change and quantization are performed to obtain the residual coefficient, and then sent to The input entropy coding module outputs...
