Claim 5:
6. The method of claim 5, wherein performing affine motion estimation on the coding block according to the candidate list corresponding to the coding mode to obtain the coding parameter corresponding to the coding block comprises:
when the coding mode is the second affine motion mode, traversing the second candidate list to acquire MVPs of at least two control points corresponding to each second reference block in the second candidate list,
calculating MVs of control points at corresponding positions of the coding block based on the MVPs of the at least two control points corresponding to each second reference block, and
acquiring a second coding parameter corresponding to the coding block from the MVs, the second coding parameter representing a group of coding parameters that are obtained in the second affine motion mode for the coding block and have a minimum coding prediction cost; and
performing predictive coding on the coding block based on the coding parameter corresponding to the coding block comprises:
performing predictive coding on the coding block based on the second coding parameter corresponding to the coding block.
