Description

In two places in EncSlice (in setUpLambda and in calculateLambda) the calculations for lambda depend on whether dependent quantization is used or not. However, in both places the checks are performed with "if( m_pcCfg->getDepQuantEnabledFlag() )" which will be true whenever dependent quantization is turned on for the sequence regardless of if the current slice has dependent quantization enabled or not. It seems to me that it would be better to check "if( slice->getDepQuantEnabledFlag()" instead so that the special lambda calculations are done only for slices that use dependent quantization.
