Hi,

I use Intel IPP Composer XE 2011 SP1 and ipp-samples_p_7.0.7.064. My machine OS in Win7  32-bit my DirectX version is 11.

When I used the VC1 decoder I got Access Violation Exception as I notice using WinDBG:

This exception may be expected and handled.
eax=00000000 ebx=0bebdb68 ecx=000000f0 edx=000000f0 esi=00094cd1 edi=0b70903c
eip=099d049d esp=09e8eca4 ebp=09b5e3c0 iopl=0 nv up ei pl nz na pe nc
cs=001b ss=0023 ds=0023 es=0023 fs=003b gs=0000 efl=00010206
*** WARNING: Unable to verify checksum for d:\UMI\ACS\Bin\Verint.MediaCore.Codecsd.dll
Verint_MediaCore_Codecsd!DecodeBlockACIntra_VC1+0x3d:
099d049d 0fb6142e movzx edx,byte ptr [esi+ebp] ds:0023:09bf3091=??

the exception occurs in DecodeBlockACIntra_VC1 - when I open this function I notice that there is define :

#ifdef VC1_VLD_CHECK

How can I enable this define? I used the build_ia32.bat (cl8) in order to built the audio-video-codecs.

Thanks for your help.

Hi Genady,

First of all it is not clear why that warning

>>*** WARNING: Unable to verify checksum for d:\UMI\ACS\Bin\Verint.MediaCore.Codecsd.dll

is diplayed? Is there any possibility that the Verint.MediaCore.Codecsd.dll is corrupted?

Can you check who is the caller of this function and what are passed parameters "DecodeBlockACIntra_VC1+0x3d:"
