good news !
I found that many fucntionswere absent in IPP4.0 , i.e. ippiAddWeighted etc.
we can find the responding function declaration in header file , but can notfind in the dll file .
what is the reason ? bugs ? or becauseit isfree version ?
Hope you give me answers!


there is no functionality limitation in evaluation version of IPP. Probably the reason is you are looking in the wrong DLL. If you are looking for ippiAddWeighted functions famility you should look in ippCV domain, because it is Computer Vision related functionality.

Your feedback about good and bad things in newest IPP version is very appreciated. It helps us to continuously improve our product and to deliver you (and all our customers) new functionality and so on.

So, you are welcome:)


Hello, I have tried to get a free license to test it, and when i fill the questionary it gives me the 999 unknow error.
What can i do?

Regards. Ben

Hi Ben,
This is just a time out error, which is usually resolved when you try to download again. If you haven't already done so, can you download again and post the results if you still have trouble?
Sorry for the inconvenience.

Dear Customer,
Could youtell us which version of IPP you are using? Could you also double check if you are loading the right version of IPP to run this demo?
If you still experience this problem in IPP 4.1, please submit a detailed report to Intel Premier Support at .

Hello !

Would you please specify what exactly new in Intel Xeon support in 4.1 version(relative to 4.0 version).

Thanks a lot .


I downloaded the evaluation version of IPP4.1 yesterday and began to use it and I got a similar error :
"The procedure entry point ofippiYUV420ToBGR_8u_P3C3R could not be located in ippi20.dll". What is the reason of that?

The Intel IPP 4.1 provide new support for Intel Xeon processors with Intel Extended Memory 64 Technology (Intel EM64T).

Please check "What's new" at for more details.


You may need to check your system to see if you have old version of IPP installed, especially in the directory system. Make sure you are not loading the older version of IPP Dll to run this demo..

I just checked this demo and it ran just fine.

Sorry if this message appears twice, but I posted it once and couldn't find it in the message listing...

We've been trying to install opencv 0.9.6.
No problem so far, except that we bought Intel's IPP library, and we
would like to have OpenCV use this library without modyfying our code.

Is there a switch (#define xxxx or like that) to make use of the
IPP library when building opencv (or our application)?

I can link the appropriate IPP libraries, but I figure that at some
point I need to tell opencv at compile time that it is supposed to use
the IPP functions rather than its own functions.

Thank you in advance for you answer,
