1457	rplIdx variable for list 1 is not always set in parseSliceHeader()	hallapur		"
setRPL1idx function is not called in the ""if"" and ""else if"" clauses in the following code in parseSliceHeader():

        if (sps->getNumRPL(1) > 1 && pps->getRpl1IdxPresentFlag())
        {
          int numBits = ceilLog2(sps->getNumRPL1());
          READ_CODE(numBits, uiCode, ""ref_pic_list_idx[1]"");
          *rpl1 = *sps->getRPLList1()->getReferencePictureList(uiCode);
        }
        else if (sps->getNumRPL(1) == 1)
        {
          *rpl1 = *sps->getRPLList1()->getReferencePictureList(0);
        }
        else
        {
          assert(pcSlice->getRPL0idx() != -1);
          pcSlice->setRPL1idx(pcSlice->getRPL0idx());
          *rpl1 = *sps->getRPLList1()->getReferencePictureList(pcSlice->getRPL0idx());
        }

This does not seem to cause problems in the decoder, but it does cause incorrect bitstream creation in some cases when decoded slice header is re-encoded such as in subpicMergeApp. I will submit a merge request that adds missing function calls.
