#790 closed defect (fixed)

Leftover disable_deblocking_filter_flag value used during slice header parsing.

Reported by: bheng Owned by:
Priority: minor Milestone: HM-9.1
Component: HM Version: HM-9.0
Keywords: Cc: fbossen, ksuehring, davidf, jct-vc@…

Description

When deblocking filter controls were included in the previous picture and deblocking was disabled, the HM-8.1 decoder fails to reset the slice_disable_deblocking_filter_flag for the current picture when deblocking filter controls are not enabled in the current picture’s PPS.

For the purpose of configuring the deblocking filter, the decoder still works correctly since this case is handled in TComLoopFilter::setCfg( ). However, re-enabling the deblocker also affects the parsing of the slice_loop_filter_across_slices_enabled_flag.

The attached patch provides one way to solve this issue.

Changing milestone. Slice header parsing is still incorrect in HM-9.0.1.
