[Mp4-tech] [Video] AVC deblocking filter

[Alan Thomson]

Hi all -
If I understand correctly, setting disable_deblocking_filter_idc to 1
completely turns off the in-loop filter. (14496-10:2003 para 8.7)
Given that the filter effectively turns itself off for small quantiser
values, and that images are likely to be blocky for larger quantiser values,
my question is:
under what circumstances would you _want_ to disable the filter? 
I'm not sure of the usefulness of this provision - am I missing something?
OK, 2 questions.
Thanks,
Alan
