Condition if( bOnlyIVP && m_pcEncCfg->getUseIVP() ) in function TEncSearch::estIntraPredQT() results in testing else case when getUseIVP() is false, but should test nothing. This only happens for non-CTC cases and only affects encoder optimization.

The bug can be fixed as follows: TEncCu.cpp:

1064a1065
>             Bool bUseIVP = true;
1072a1074
>               bUseIVP = m_pcEncCfg->getUseIVP();
1073a1076,1077
>             if( bUseIVP )
>             {
1106a1111,1113
> #if HHI_DMM4_ENC_I0066
>           }
> #endif

TEncSearch.cpp:

3142,3144
< #if SEPARATE_FLAG_I0085
<       if( bOnlyIVP && m_pcEncCfg->getUseIVP() )
< #else
3146d3142
< #endif

An element name of poc_lsb_not_present_flag[] in slice_segment_header(),i.e., if( nuh_layer_id > 0 && poc_lsb_not_present_flag[ nuh_layer_id ] | | ( nal_unit_type != IDR_W_RADL && nal_unit_type != IDR_N_LP ) )is missed in WD.

nuh_layer_id should be changed to LayerIdxInVPS[nuh_layer_id].

The decoder picture hash doesn't work in enhancement layer.

This is because encoder always send the decoded picture hash SEI with nal_layer_id equal to 0. The decoder decodes the SEI in enhancement layer but interprets that is associated with base layer.

A patch is attached.
