Description

In 8.5.6.3.4 Chroma sample interpolation process, why is the unclipped value for xInti different based on the value of subpic_treated_as_pic_flag[ SubPicIdx ]?
xInti = Clip3( SubPicLeftBoundaryPos / SubWidthC, SubPicRightBoundaryPos / SubWidthC, xIntL + i )
vs.
xInti = Clip3( 0, picWC − 1, sps_ref_wraparound_enabled_flag ? ClipH( xOffset, picWC, xIntC + i − 1 ) : xIntC + i − 1 )
Shouldn't the unclipped value be xIntC + i − 1 in both cases, especially considering that xIntL is not defined in this process?
Same comment for yInti
