Since the value of chroma offset is always held in 8bit (see equations (8-224) and (8-225)), the predicted value of chroma offset must be also held in 8bit. The original source code in the function of TDecCavlc::xParsePredWeightTable( TComSlice* pcSlice ) should be modified simply as follows (same for TEncCavlc): --------- '''Original;''' Int shift = ((1<<(g_uiBitDepth+g_uiBitIncrement-1))); --------- '''Modified;''' Int shift = 128; The modified patch is provided in this ticket.
