In SHM-5.1-dev r614, the DPB-parameters in SPS are inferred when they are not signalled for nuh_layer_id greater than 0. The following inference in TDecCavlc.cpp:parseSPS() is incorrect because the inference rule is dependent on which layer accesses the SPS; that information will be unavailable at the point of parsing the SPS and hence the following should not be included in parseSPS().

for(UInt i=0; i <= pcSPS->getMaxTLayers()-1; i++) {

pcSPS->setMaxDecPicBuffering( parameterSetManager->getPrefetchedVPS(pcSPS->getVPSId())->getMaxVpsDecPicBufferingMinus1( parameterSetManager->getPrefetchedVPS(pcSPS->getVPSId())->getTolsIdx(), pcSPS->getLayerId(), i)+1, i);

}

In some places, the SPS layer ID is used instead of the slice layer ID, which could be wrong in many cases.

Attached ticket fixes this issue.

The array m_maxTSLayerMinus1 is declared in TComSlice.h as

UInt m_maxTSLayerMinus1[MAX_VPS_LAYER_ID_PLUS1 - 1];

It should be

UInt m_maxTSLayerMinus1[MAX_VPS_LAYER_ID_PLUS1];

because the #sub-layers is signalled for each layer; hence "-1" should not be there.
