1. A method for obtaining a candidate motion vector list, the method comprising:
when a left candidate picture block spatially neighboring to a current block is encoded or decoded and an inter prediction mode is used for the left candidate picture block, determining whether a reference picture of the left candidate picture block is the same as a reference picture of the current block; and
constructing a candidate motion vector list for the current block based on a result of the determining, wherein:
when the reference picture of the left candidate picture block is the same as the reference picture of the current block, the candidate motion vector list comprises a motion vector (MV) of the left candidate picture block; and
when the reference picture of the left candidate picture block is different from the reference picture of the current block, the MV of the left candidate picture block is not used to construct the candidate motion vector list.
