1449	Incorrect offset derivation in Eq 8-10x from chroma format for CPR	cgisquet		"Current formulas in 8.5.3.2.1 are:
offsetX = ( ChromaArrayType == 0 ) ? 0 : ( mvCLX[ 0 ] & 0x7 ? 2 : 0 )	(8-106)
offsetY = ( ChromaArrayType == 0 ) ? 0 : ( mvCLX[ 1 ] & 0x7 ? 2 : 0 )	(8-107)
They seem to enforce using an offset even for 4:4:4 with odd mvCLX coordinates.

These formulae should probably read something like:
offsetX = ( ChromaArrayType != 1 && ChromaArrayType != 2 ) ? 0 : ( mvCLX[ 0 ] & 0x7 ? 2 : 0 )	(8-106)
offsetY = ( ChromaArrayType != 1 ) ? 0 : ( mvCLX[ 1 ] & 0x7 ? 2 : 0 )	(8-107)
to properly account for 4:2:0 and 4:2:2.

Note: there does not seem to be an appropriate version for the SCC text."	defect	closed	major		SCC text		fixed	CPR, interpolation	patrice.onno@… rajan_joshi jct-vc@…
