#401 closed enhancement (fixed)

DeblockingFilterControlPresent parameter misleading

Reported by: ksuehring Owned by: karlsharman
Priority: minor Milestone: HM-16.5
Component: HM Version: HM-6.0
Keywords: loop filter Cc: fbossen, ksuehring, davidf, jct-vc@…

Description

I think the DeblockingFilterControlPresent parameter is rather confusing at the encoder. I think the value of deblocking_filter_control_present_flag should automatically be determined based on the deblocking filter control parameters, i.e. if one of them has a non-default value this value should be included in the bitstream.

For instance for disabling the deblocking filter the user will currently have to set DeblockingFilterControlPresent=1 AND LoopFilterDisable=1 which is not very intuitive.

There is also no documentation on these parameters on the command line help and only outdated information in the software manual.
