In JVET-Q2001-vD,

refWraparoundEnabledFlag is miss-aligned inputs of between and
– The luma prediction sample value predSamplesLXL[ xL ][ yL ] is derived by invoking the luma sample bilinear interpolation process specified in clause with ( xIntL, yIntL ), ( xFracL, yFracL ), refPicLXL and refWraparoundEnabledFlag as inputs.
Inputs to this process are:
– a luma location in full-sample units ( xIntL, yIntL ),
– a luma location in fractional-sample units ( xFracL, yFracL ),
– the luma reference sample array refPicLXL.
Output of this process is a predicted luma sample value predSampleLXL

Suggested fix:

1) add
"– a variable refWraparoundEnabledFlag indicating whether horizontal wrap-around motion compensation is enabled."
to the inputs of


2) remove "refWraparoundEnabledFlag" as inputs in if refWraparoundEnabledFlag is a global variable

Good catch, thanks!
