Equation(8-9) in spec:

for(rIdx = 0; rIdx <= num_ref_idx_l0_active_minus1; rIdx++)
    RefPicList0[rIdx] = ref_pic_list_modification_flag_l0 ? RefPicListTemp0[list_entry_l0[rIdx]] : RefPicListTemp0[rIdx]
if(pps_curr_pic_ref_enabled_flag && !ref_pic_list_modification_flag_l0 && NumRpsCurrTempList0 > (num_ref_idx_l0_active_minus1 + 1))
    RefPicList0[num_ref_idx_l0_active_minus1] = currPic

But function TComSlice::setRefPOCListSliceHeader() in HM16.15_SCM8.4:

  for (Int rIdx = 0; rIdx < m_aiNumRefIdx[REF_PIC_LIST_0]; rIdx ++)
  {
    cIdx = m_RefPicListModification.getRefPicListModificationFlagL0() ? m_RefPicListModification.getRefPicSetIdxL0(rIdx) : rIdx % numPicTotalCurr;
    assert(cIdx >= 0 && cIdx < numPicTotalCurr);
    m_aiRefPOCList[REF_PIC_LIST_0][rIdx] = rpsPOCCurrList0[cIdx];
  }

  if ( m_eSliceType != B_SLICE )
  {
    m_aiNumRefIdx[REF_PIC_LIST_1] = 0;
  }
  else
  {
    // Equation (8-11)
    for (Int rIdx = 0; rIdx < m_aiNumRefIdx[REF_PIC_LIST_1]; rIdx ++)
    {
      cIdx = m_RefPicListModification.getRefPicListModificationFlagL1() ? m_RefPicListModification.getRefPicSetIdxL1(rIdx) : rIdx % numPicTotalCurr;
      assert(cIdx >= 0 && cIdx < numPicTotalCurr);
      m_aiRefPOCList[REF_PIC_LIST_1][rIdx] = rpsPOCCurrList1[cIdx];
    }
  }

It is necessary to insert if clause. For example:

  if (getPPS()->getPpsScreenExtension().getUseIntraBlockCopy() &&
    !m_RefPicListModification.getRefPicListModificationFlagL0() && numPicTotalCurr > m_aiNumRefIdx[REF_PIC_LIST_0])
  {
    m_aiRefPOCList[REF_PIC_LIST_0][m_aiNumRefIdx[REF_PIC_LIST_0]-1] = getPOC();
  }

In TEncSearch.cpp between line 1493 and 1494, as well as between line 7039 and 7040, the following three lines need to be added:

#if HHI_MRG

m_pcEntropyCoder->encodeMergeInfo( pcCU, 0, true );

#endif

This fixes the issue, that an incorrect bitrate is estimated for RD-decisions.

In TEncEntropy.cpp between line 382 and 383, the following needs to be added:

if ( pcCU->getSlice()->isIntra() ) {

return;

}

This avoids the encoding of unwanted merge flags.

In TEncEntropy.cpp between line 900 and 901, the following needs to be added:

if( bRD )

uiAbsPartIdx = 0;

This corrects a wrong determination of merge candidates during the estimation process.

All line numbers are valid for version 0.6.

When using encoder_lowdelay.cfg with parameter "GOPSize" set to 4 and parameter "RateGOPSize" set to 4, the decoder crashes at POC 5:

Assertion failed: 0, file ..\..\source\Lib\TLibCommon\TComBitStream.cpp, line 153

The sequence-specific config file used was per-sequence/BlowingBubbles.cfg with parameter "FrameToBeEncoded" set to 10.
