( (shift*ChromaWeightL0[ i ][ j ]) >> ChromaLog2WeightDenom ) − shift ) where shift is 1 << BitDepth In the HM, the shift value is set to the incorrect value of g_uiIBDI_MAX>>1 (e.g., 127 instead of 128). For example in line 2694 of TDecCAVLC.cpp: wp[j].iOffset = iDeltaChroma - ( ( (g_uiIBDI_MAX>>1)*wp[j].iWeight)>>(wp[j].uiLog2WeightDenom) ) + (g_uiIBDI_MAX>>1); " defect closed minor HM-7.2 HM HM-7.1 fixed fbossen ksuehring davidf jct-vc@…
