Abstract:
A video encoder performs an Advanced Motion Vector Prediction (AMVP) process for a current block of a current picture. As part of performing the AMVP process, the video encoder may determine whether local illumination compensation (LIC) is being applied in the AMVP process. Based on LIC being applied in the AMVP process, the video encoder may skip a bi-directional AMVP motion estimation process that sets a cost associated with encoding the current block using a bi-directional AMVP mode. Rather, the video encoder may set the cost to a maximum cost value.
