The location (xCb, yCb) input to appears to be intended to be in sample units of the colour component cIdx. In it is described as a luma location when invoking This seems incorrect. It is also inconsistent with other usage of (xCb, yCb) in
Furthermore, in, these locations are compared to virtual boundary locations without appropriate scaling related to chroma subsampling.

Good catch, thanks! Fixed in JVET-S2001-vE by removing "luma" in the invocation and scaling the virtual boundary locations according to scaleWidth and scaleHeight.

Note that scaleWidth and scaleHeight should be locally defined. Currently they are only locally defined in the SAO process.

Reopening since scaleWidth and scaleHeight do not appear to be appropriately defined in JVET-S2001-vE

Thanks, both will be defined in deblocking as well in JVET-S2001-vF.
