Description

Software version: TMuC 0.8
File TComPredFilter.h
Function: inline Void TComPredFilter::xCTI_FilterDIF_TEN(...)

case 13:

for (Int y=0; y<iHeight; y++)
{

piSrcTmp = piSrc-2*iSrcStride-2;
for ( Int x = 0; x < iWidth; x++, piSrcTmp++)

piDst[x*iDstStep] = Clip( (2*piSrcTmp[0*iSrcStride+5] + (-10)*piSrcTmp[1*iSrcStride+4] + 111*piSrcTmp[2*iSrcStride+3] + 37*piSrcTmp[3*iSrcStride+2] + (-10)*piSrcTmp[4*iSrcStride+1] + 2*piSrcTmp[5*iSrcStride+0] + 64)>>7);

piSrc += iSrcStride;
piDst += iDstStride;

}
break;

Should be changed to:
piDst[x*iDstStep] = Clip( (2*piSrcTmp[0*iSrcStride+5] + (-10)*piSrcTmp[1*iSrcStride+4] + 37*piSrcTmp[2*iSrcStride+3] + 111*piSrcTmp[3*iSrcStride+2] + (-15)*piSrcTmp[4*iSrcStride+1] + 3*piSrcTmp[5*iSrcStride+0] + 64)>>7);
