In the VTM-5.0 code, in function xEdgeFilterChroma, the position for the horizontal CTU boundary seems to be computed incorrectly, which is as follows: pos.y % cuP.slice->getSPS()->getCTUSize() == 0 which does not take into account the Chroma re-scaling based on the Chroma format. A possible fix could be as follows: (pos.y % (cuP.slice->getSPS()->getCTUSize() >> ::getComponentScaleX(COMPONENT_Cb, nChromaFormat)) == 0)" defect closed minor VTM VTM-5.0 invalid Longer tap deblocking for Chroma ksuehring XiangLi fbossen jvet@…
