Description

In function PU::getInterMergeCandidates (UnitTools.cpp),

in part related to 8.5.2.11 Derivation process for temporal luma motion vector prediction:
If ph_temporal_mvp_enabled_flag is equal to 0 or
(cbWidth*cbHeight) is less than or equal to 32,
both components of mvLXCol are set equal to 0 and availableFlagLXCol is set equal to 0

In VTM implementation, 12 is present instead of 32 (probably a typo).

I missed the fact that VTM checks this with an addition instead of multiplication.

cbWidth + cbHeight > 12, instead of cbWidth * cbHeight > 32.

Both conditions are equivalent.

Thus, this ticket can be closed.
