[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...
