207	HM4.0 encoder issue on chroma ALF for multiple slice coding	yamakage		"ALF coefficient design for Cr uses Cb information when coding multiple slices per picture.  This does not affect coding results for the common test conditions (i.e., single slice per picture), but affects when multiple slice coding is enabled such as CE8.c.5 and CE8.c.6.

Suggested change is as follows:

In TEncAdaptiveLoopFilter.cpp, line 6130,

      xCalcCorrelationFuncforChromaSlices(ALF_Cb, pOrg, pCmp, iShape, pcPicOrg->getCStride(), pcPicDec->getCStride());

should be modified to the following:

      xCalcCorrelationFuncforChromaSlices(ALF_Cr, pOrg, pCmp, iShape, pcPicOrg->getCStride(), pcPicDec->getCStride());

(the first argument should be modified from ALF_Cb to ALF_Cr.)
