Integration of O0650 (Chroma Mapping Table) with O0919 (TS Min QP)

Description

When both O0919 and O0650 are enabled, the chroma QP mapping table fails to use the Joint Cb/Cr table where it's supposed to.

Specifically, in the following line of QpParam::QpParam( )

#if JVET_O0919_TS_MIN_QP
#if JVET_O0650_SIGNAL_CHROMAQP_MAPPING_TABLE

*this = QpParam(QP <= -MAX_INT ? tu.cu->qp : QP,

compID, <-- should depend on useJQP

tu.cs->sps->getQpBDOffset(toChannelType(compID)), tu.cs->sps->getMinQpPrimeTsMinus4(toChannelType(compID)), chromaQpOffset, tu.chromaFormat, dqp, tu.cs->sps);

#else
