Potential bug in TComPrediction::motionCompensation

Reported by: libin Owned by:
Priority: minor Milestone:
Component: HM Version: HM-8.0
Keywords: Cc: fbossen, ksuehring, davidf, jct-vc@…

Description

There are below lines in TComPrediction::motionCompensation()

if( pcCU->getSlice()->getPPS()->getUseWP())
{

xPredInterUni (pcCU, uiPartAddr, iWidth, iHeight, eRefPicList, pcYuvPred, iPartIdx, true );

}
else
{

xPredInterUni (pcCU, uiPartAddr, iWidth, iHeight, eRefPicList, pcYuvPred, iPartIdx );

}
xPredInterUni (pcCU, uiPartAddr, iWidth, iHeight, eRefPicList, pcYuvPred, iPartIdx );

I think the last xPredInterUni() is unnecessary.
This problem may be caused by removal the macro of WEIGHT_PRED.
Please refer to ​http://hevc.kw.bbc.co.uk/trac/changeset/1840/branches/HM-5.1-dev-cleanup/source/Lib/TLibCommon/TComPrediction.cpp for more information.
In my opinion, the line 482(474) should be removed together with WEIGHT_PRED.
