1. A decoding method, applied to a decoder and comprising:
obtaining an encoding result of a current block, a target index for the current block, and a block-coding enable flag for the current block by parsing a bitstream;
obtaining a feature map splicing order;
determining target block-coding motion information corresponding to the target index based on the feature map splicing order and pixel position information of the current block when the block-coding enable flag is valid; and
decoding the encoding result of the current block based on the target block-coding motion information.
