1. A method for video encoding comprising:
partitioning a video picture into a plurality of coding units (CUs), wherein at least one of the plurality of CUs is further partitioned into two prediction units (PUs); and
in response to determining that a current CU is coded in an inter prediction mode,
signaling coded information for inferring whether the current CU is coded in triangle prediction mode; and
in response to determining that the current CU is coded in the triangle prediction mode, signaling a partition orientation syntax element indicating a partitioning orientation, and signaling index values corresponding to uni-prediction motion vector candidates;
wherein the coded information comprises a triangle prediction tool enable/disable flag signaled in sequence parameter set (SPS), and the current CU is inferred as not being coded in the triangle prediction mode in response to determining that the triangle prediction tool enable/disable flag is false.
