1. A method for decoding, comprising:
decoding a syntax element representative of a first merging candidate index of a triangular shape based motion compensation candidates list;
if a number of candidates in the triangular shape based motion compensation candidates list is larger than 2, then a signaling of a second merging candidate index in the triangular shape based motion compensation candidates list is skipped and a second merging candidate index in the triangular shape based motion compensation candidates list is derived from the first merging candidate index using a mapping function; and
decoding a block of a picture by performing a triangular shape based motion compensation using motion information of a merging candidate at a position indicated by the first merging candidate index in the triangular shape based motion compensation candidates list and of a merging candidate at a position indicated by the second merging candidate index in the triangular shape based motion compensation candidates list.
