Video encoding method and apparatus, video decoding method and apparatus, computer device, and storage medium

A computer device, comprising:

• a processor;
• and
• memory, the memory storing a plurality of computer programs that, when executed by the processor, cause the computer device to perform a plurality of operations including:
• obtaining a to-be-encoded current block in a current video frame;
• obtaining a first reference block corresponding to the current block in a reference video frame;
• obtaining, within the reference video frame, one or more second reference blocks matching the first reference block, the one or more second reference blocks and the first reference block being similar reference blocks;
• and
• encoding the current block according to the first reference block and the one or more second reference blocks, to obtain encoded data, including:
• performing image fusion according to the first reference block and the one or more second reference blocks, to obtain a first fused reference block;
• and
• selecting a target reference block from the first fused reference block and the first reference block;
• and
• encoding the current block according to the target reference block, to obtain the encoded data, the encoded data carrying reference block mode information corresponding to the target reference block.

A non-transitory computer-readable storage medium, storing a plurality of computer programs, the plurality of computer programs, when executed by a processor of a computer device, causing the computer device to perform a plurality of operations including:

• obtaining a to-be-encoded current block in a current video frame;
• obtaining a first reference block corresponding to the current block in a reference video frame;
