Abstract: This application provides an inter prediction method and apparatus, a video encoder, and a video decoder. The method includes: determining N target picture blocks from M picture blocks in which M neighboring locations of a current picture block are respectively located, where any two of the N target picture blocks are different, M and N are both positive integers, and M is greater than or equal to N; determining candidate motion information of the current picture block based on motion information of the N target picture blocks, and adding the candidate motion information of the current picture block to a motion information candidate list of the current picture block; and performing inter prediction on the current picture block based on the motion information candidate list. In this application, comparison operations during obtaining of the motion information candidate list can be reduced, to improve inter prediction efficiency.

Abstract: A motion information candidate list construction method includes: performing a first processing process on all neighboring image blocks of a current image block until a quantity of candidate motion information sets in a candidate motion information list is equal to a first preset value or all the neighboring image blocks are traversed; then traversing at least two extra to be selected motion information sets, and storing, in the candidate motion information list, an extra to be selected motion information set that satisfies a preset condition, until the quantity of candidate motion information sets in the candidate motion information list is equal to a preset quantity value or the extra to be selected motion information sets are traversedextra to be selected motion.
