Q0346 proposed to add back slice level on/off control of LMCS. The slice header syntax has been added in Q2001-vA but the controls in low level decoding process haven't been updated properly. To be specific:

In When cIdx is equal to 0 and ph_lmcs_enabled_flag is equal to 1, ...

should be: When cIdx is equal to 0 and slice_lmcs_enabled_flag is equal to 1, ...

Depending on the value of ph_lmcs_enabled_flag, the following applies:
– If ph_lmcs_enabled_flag is equal to 0, ....
– Otherwise (ph_lmcs_enabled_flag is equal to 1),....

should be:
Depending on the value of slice_lmcs_enabled_flag, the following applies:
– If slice_lmcs_enabled_flag is equal to 0, ....
– Otherwise (slice_lmcs_enabled_flag is equal to 1),....

– ph_chroma_residual_scale_flag is equal to 0.

should be
– ph_chroma_residual_scale_flag is equal to 0 or slice_lmcs_enabled_flag is equal to 0.

In If ph_lmcs_enabled_flag of the slice that ...

should be: If slice_lmcs_enabled_flag of the slice that ...
