Description
In the current spec text, alf_chroma_num_alt_filters_minus1 is not restricted (coded in ue(v)) which leads to unlimited ALF APS size. Per the adoption of JVET-O0090 variant CE5-4.2, the maximum value of alf_chroma_num_alt_filters_minus1 should be set to 7. The proponents might want to confirm the design intent.
Suggested changes:
replace
alf_chroma_num_alt_filters_minus1 plus 1 specifies the number of alternative filters for chroma components.
with
alf_chroma_num_alt_filters_minus1 plus 1 specifies the number of alternative filters for chroma components. The value of alf_chroma_num_alt_filters_minus1 shall be in the range of 0 to 7, inclusive.
