Abstract
(EN)
Methods and apparatuses are provided for video coding. The method includes: partitioning video pictures into a plurality of coding units (CUs), at least one of which is further partitioned into two prediction units (PUs) including at least one geometric shaped PU; obtaining a first merge list including a plurality of candidates, each including one or more motion vectors; and obtaining a uni-prediction merge list for the geometric shaped PU; where the uni-prediction merge list including a plurality of uni-prediction merge candidates, and each uni-prediction merge candidate includes one motion vector of a corresponding candidate in the first merge list.
