Description
In 8.5.8.2 Weighted sample prediction process for triangle merge mode, there is a mismatch between VTM and the specification for the calculation of the weight when the width of the block is less than its height.
In the four equations (8-891) (8-892) (8-893) and (8-894), "x / nCbR - y" should be replaced by "x - y / nCbR" when nCbW < nCbH (i.e. after ":").
