Method, device, equipment and storage medium for determining an encoding mode

Abstract

The embodiment of the present invention discloses a method, device, device, and storage medium for determining a coding mode, wherein the method includes: dividing a coding unit under each coding standard into a coding unit under the next coding standard adjacent to the coding standard transformation unit, and calculate the coding cost of each transformation unit; sequentially perform cost optimization integration on the coding unit and transformation unit under the same coding specification, and obtain the overall coding mode under the optimal coding cost. The technical solution provided by the embodiment of the present invention enables the encoding cost to be minimized when the overall encoding mode is used for video encoding, ensures the adaptability of the video encoding mode adopted under different videos, reduces the computational overhead of video encoding, and further improves Video encoding rate.

Description

technical field

[0001] The embodiments of the present invention relate to the technical field of video coding, and in particular, to a method, device, device and storage medium for determining a coding mode. Background technique

[0002] At present, video coding is usually coded with the coding unit (Coding Unit, CU) as the basic unit. At this time, the coding unit CU has four sizes: 64*64, 32*32, 16*16, and 8*8. All of them need to recursively try the quadtree from the 64*64 size CU to the 8*8 size CU in order to select the coding size with the best efficiency. At this time, the recursion depth of the 64*64 size CU is 0 , adding 1 to the depth of each downward recursion, and the recursion depth of the 8*8 size CU is 3. At the same time, at each recursion depth, the encoding cost of the current non-recursive CU and the current CU are divided after recursion Compare the sum of the coding costs of the 4 small CUs to determine whether recursive partitioning is required at this...
