  • Milestone set to v5
  • Version changed from RExt D7 (Q1005) v8 to v4 (12/2016)

Agreed by the authors of the AHG2 report JCTVC-AD0002 (checked 2016/12 release of the HEVC specification).
Fix:
In 8.5.2, change
the luma location ( xBl, yBl ) set equal to ( nCS1L + ( nCbSL >> 2 ), 0 )
to
the luma location ( xBl, yBl ) set equal to ( ( nCbSL >> 1 ) + ( nCbSL >> 2 ), 0 )
