1. A method of encoding a video sequence into a bitstream, the method comprising:
receiving a video sequence;
encoding one or more pictures of the video sequence; and
generating a bitstream, wherein the encoding comprises:
inserting a set of spatial merge candidates to a merge candidate list of a coding block, wherein:
when the coding block is part of low-delay pictures, the set of spatial merge candidates are inserted according to a first construction order;
when the coding block is part of non-low-delay pictures, the set of spatial merge candidates are inserted according to a second construction order, the first construction order being different from the second construction order; and
adding to the merge candidate a zero motion vector, wherein the zero motion vector is inserted an end of the merge candidate list until a maximum merge candidate number is reached.
