Meeting Notes
JVET-R0341 AHG9: on constraint flag for local chroma QP control [Philippe de Lagrange, Karam Naser, Philippe Bordes, Fabrice Le Léannec (InterDigital)]

The constraint flags defined in the current VVC draft allow disabling local luma QP control, using no_qp_delta_constraint_flag. This contribution proposes several methods to allow constraint flags to disable local chroma QP control too.

The proponent suggested to focus only on option 2, which proposes a no_chroma_qp_offset_constraint_flag.

Decision (general constraints cleanup): Adopt option 2.
