Embodiment 1

[0070] A video encoding method provided by an embodiment of the present invention, such as image 3 Shown, including:

[0071] Step S301: Obtain prediction data of a target coding unit, where the target coding unit is a coding unit obtained by dividing a frame to be coded, and the target coding unit is a coding unit currently to be processed;

[0072] Step S302, based on the prediction data, execute the first process and the second process in parallel, where the first process is a process of obtaining reference data based on the prediction data, and the second process is a process of obtaining the encoding result of the target coding unit based on the prediction data, wherein,

[0073] The reference data is the reference data for intra prediction of the next coding unit to be processed.

[0074] It should be noted that the video encoding process needs to first divide the frame to be encoded into blocks. The block size of the AVS2 video encoding technology is mostly 64x64. One block is ...

Abstract

The invention provides a video encoding method and apparatus, and relates to the field of video encoding technology. The method comprises the following steps: acquiring prediction data of a target encoding unit, wherein the target encoding unit is an encoding unit obtained after a to-be-encoded frame is divided, and the target encoding unit is a to-be-processed encoding unit at present; based on the prediction data, executing a first process and a second process in parallel, wherein the first process is a process of obtaining reference data based on the prediction data, the second process is aprocess of obtaining an encoding result of the target encoding unit based on the prediction data, and the reference data are reference data of the next to-be-processed encoding unit to perform intra-frame prediction. By adoption of the video encoding method and apparatus, the technical problem that the existing AVS2 encoding technology cannot achieve real-time encoding is solved.

Description

Technical field [0001] The present invention relates to the technical field of video coding, in particular to a video coding method and device. Background technique [0002] AVS2 is a brand new video coding technology proposed by the AVS standard group in 2016. AVS2 uses a traditional hybrid coding framework. The entire coding process includes steps such as intra prediction, inter prediction, transform quantization, loop filtering, and entropy coding. It has the characteristics of high coding complexity, large coding image size, and long coding time. Therefore, the pressure of real-time coding is quite large, and the main frequency of the coding chip needs to meet very high requirements. [0003] In view of the small room for improvement of the main frequency of the current encoding chip, the method of rapidly increasing the number of encoding cores is currently used to meet the real-time encoding requirements of the AVS2 video encoding technology. In this case, because the curren...
