Description

In the luma sample interpolation process (clause 8.3.4.3.2), the input luma location in full-sample units ( xIntL, yIntL ) may be outside of the picture. However, clipping to the picture boundaries in only applied in the dimension for which interpolation is performed. Clipping to the picture boundaries should be added even when no interpolation is performed in a dimension:

  • Clipping of xIntL and yIntL should be added in equation (8-359)
  • Clipping of yIntL should be added in equation (8-360)
  • Clipping of xIntL should be added in equation (8-361)

The chroma sample interpolation process (clause 8.3.4.3.3) has the same problem.
