Abstract

The present application provides a video encoding method, system and storage medium, through the first encoding pipeline stage: performing integer pixel motion estimation on the current CTU to obtain the integer pixel motion estimation result; the second encoding pipeline level: according to the integer pixel motion estimation result Judging the current CTU motion intensity; determining the specific task of sub-pixel motion estimation according to the current CTU motion intensity, and making mode decisions according to the current CTU motion intensity; wherein, the pipeline time slice of the second encoding pipeline level is fixed, and the sub-pixel motion estimation needs When the time slice decreases, the time slice of mode decision increases. This application combines the traditional pipeline-level sub-pixel motion estimation FME and mode decision-making MD into a single CTU-level processing pipeline, which reduces unnecessary encoding time in the encoding process, and greatly improves the encoding by flexibly adjusting the overall encoding space and time. performance.

Description

technical field [0001] The present application belongs to the technical field of digital signal processing, and in particular relates to a video encoding method, system and storage medium. Background technique [0002] Video compression, also known as video coding, aims to eliminate redundant information between video signals. Continuously optimized video coding standards help to further improve the compression efficiency of video images and reduce the cost of video image storage and network transmission, including the latest AVS3, AV1, H.266 and other video coding standards. However, these new video coding standards employ larger processing units, more candidate modes, and higher data dependencies. This means that the new video coding standard has higher processing complexity, longer video compression time, more resources required, and higher parallel design difficulty, all of which put forward higher requirements for the design of high-performance hardware video encoders....
