Encoder Bug in HM-6.0 on ALFMaxNumFilter

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

Description

In HM-6.0 picture-based ALF encoder, ALFMaxNumFilter is used incorrectly to derive TEncAdaptiveLoopFilter::m_alfPQTMaxDepth.

When ALFMaxNumFilter==16, m_alfPQTMaxDepth shall be equal to or less than 2.
However, m_alfPQTMaxDepth can be more than 2 even if ALFMaxNumFilter == 16.

In order to solve the issue, the attached patch is suggested.

Note that in the common test condition, this fix will affect only HE10-RA (picture-based encoding with ALF) case.
