However, in VTM7.0 function PU::getInterMergeSubPuMvpCand(), current processing CU's top-left position is used instead. centerPos.x = puPos.x + (puSize.width >> 1) + tempX; centerPos.y = puPos.y + (puSize.height >> 1) + tempY; clipColPos(centerPos.x, centerPos.y, pu); centerPos = Position{ PosType(centerPos.x & mask), PosType(centerPos.y & mask) }; Suggest to align the text with VTM. A quick fix is to remove the definition of (xColCtrCb, yColCtrCb) and replace with (xCtrCb, yCtrCb). ",defect,closed,minor,,spec,VVC D7 vE,fixed,,ksuehring bbross XiangLi fbossen jvet@…
