1257	Chroma subsampling directions are transposed in weighted prediction	jackh		"I'm surprised that this one is not on the bug tracker as it's clearly been spotted already. In HM-13.0+RExt-6.0, TComWeightPrediction.cpp, there are two pairs of lines like this:

{{{
    const Int  iHeight     = uiHeight>>csx; // TODO: RExt - fix this bug
    const Int  iWidth      = uiWidth>>csy;  // TODO: RExt - fix this bug
}}}

The shifts are transposed. The correct code would be:

{{{
    const Int  iHeight     = uiHeight>>csy;
    const Int  iWidth      = uiWidth>>csx;
}}}

This occurs in both TComWeightPrediction::addWeightBi() and Void TComWeightPrediction::addWeightUni(). I'm slightly confused as to why such a simple fix was marked as a TODO!"	defect	closed	minor	HM+RExt-4.2	HM RExt	RExt-4.1 (HM-12.0)	fixed		davidf karlsharman jct-vc@…
