Description
In 8.8.3.6.7 Filtering process for a luma sample using long filters
the equation (8-1167):
“refMiddle = ( p4 + p3 + 2* ( p2 + p1 + p0 + q0 + q1 + q2 ) + q3 + q4 + 8 ) >> 4 (8-1167)”
should be updated to:
“refMiddle = ( p5 + p4 + p3 + 2* ( p2 + p1 + p0 + q0 + q1 + q2 ) + q3 + q4 + q5 + 8 ) >> 4 (8-1167)”
