Description

I found erroe related to ticket#168 in HM3.0 so I modified the (TEncAdaptiveLoopFilter.cpp, TEncAdaptiveLoopFilter.h) files as suggested by Chih-Ming in jct-vc Digest, Vol 16, Issue 66,
but now I am getting error of corrupted heap , I tried to run this on other computers but they are also giving the same error chih-ming suggested it is the bug associate with TComPicSym::destroy()function.
I found the error in the memory allocation.

encoder config file

comment:1 Changed 13 years ago by ksuehring

I tried the used configuration with the current HM-3.1-dev r990 plus r951, the fix for #168 in HM-3.0-dev-mediatek.

The merged TEncAdaptiveLoopFilter.cpp and TEncAdaptiveLoopFilter.h look quite different than those provided in the email.

The setting

QuadtreeTULog2MinSize : 4

triggers an assert in

Assertion failed: 16 == uiNumCoeffPerAbsPartIdxIncrement, file ..\..\source\Lib\TLibEncoder\TEncSearch.cpp, line 4698

If I decrease the parameter to 2 encoder and decoder run without problems (Windows,Linux/both 64-bit)

  • Summary changed from currupted heap after appling ticket#168 solution to corrupted heap / assert failed for QuadtreeTULog2MinSize: 4

I can reproduce the heap corruption using HM 2.2 with the config file (Windows x64). It happens only for QuadtreeTULog2MinSize: 4.
