#1072 closed defect (fixed)

numDU = 0 causes divide by zero, run time error

Reported by: gregcoppa Owned by:
Priority: minor Milestone: HM-11.0
Component: HM Version: HM-10.0
Keywords: Cc: fbossen, ksuehring, davidf, jct-vc@…

Description

In TEncGOP::compressGOP(...) numDU is initialized to zero for SliceMode != 1:

UInt numDU = ( m_pcCfg->getSliceMode() == 1 ) ? ( pcPic->getNumCUsInFrame() / maxCU ) : ( 0 );

this leads to a divide by zero when SliceMode == 0 in the following call:

pcSlice->getSPS()->setHrdParameters( m_pcCfg->getFrameRate(), numDU, m_pcCfg->getTargetBitrate(), ( m_pcCfg->getIntraPeriod() > 0 ) );

...

ducpbSizeValue = bitRate/numDU;

Not sure how to best prevent this - greg
