487	Mismatch between spec text and vtm on long-tap filter	wzeng		"In JVET-O2001-vE 8.8.3.6.7,
–	Otherwise, if one of the following conditions are true,
  –	maxFilterLengthQ is equal to 7 and maxFilterLengthP is equal to 5, 
  –	maxFilterLengthQ is equal to 5 and maxFilterLengthP is equal to 7,
the following applies:
refMiddle = ( p4 + p3 + 2* ( p2 + p1 + p0 + q0 + q1 + q2 ) + q3 + q4 + 8 )  >>  4	      (8-1178)

While in VTM6.0 function LoopFilter::xFilteringPandQ(),
    if (newNumberPSide == 7 && newNumberQSide == 5)
    {
      refMiddle = (2 * (srcP[0] + srcQ[0] + srcP[-offset] + srcQ[offset]) + srcP[-2 * offset] + srcQ[2 * offset] + srcP[-3 * offset] + srcQ[3 * offset] + srcP[-4 * offset] + srcQ[4 * offset] + srcP[-5 * offset] + srcQ[5 * offset] + 8) >> 4;
    }

I think VTM6.0 is correct. The spec text should be corrected to:

refMiddle=(2 ∗ (q0 + p0 + p1 + q1) + q2 + p2 + q3 + p3 + q4 + p4 + q5 + p5 + 8) >> 4      (8-1178)
