Extra data in SPS?

I'm working with a DynaColor H264 camera (using IPP to write a decoder). I'm playing games with the max_frame_buffering value to minimize latency. This requires that I unpack and repack the SPS. But (unless I'm making a dumb mistake) there seem to be 2 extra values at the end of this camera's SPS. I get 25 bytes (the '54' is the last one).

unsigned char src[256] = {

0x4d, 0x60, 0x1f, 0x8d, 0x68, 0x0c, 0x81, 0x37, 0xe5, 0xc0,

0x5b, 0x20, 0x00, 0x00, 0x03, 0x00, 0x20, 0x00, 0x00, 0x03,

0x00, 0xa1, 0xe2, 0x84, 0x54, 0x00, 0x00, 0x00, 0x00, 0x00

};

Difficulty understanding FFT documentation

I'm having a hard time understanding the docs for implementing an FFT , and some other minor issues.

1) when I look at the intel folder in my build environment, I see several dynamic libraries. Which one is necessary to implement the FFT

2) Also not clear if I should be using mkl instead of ipp for FFT

3) In trying to follow the example for using the FFT here : https://software.intel.com/en-us/articles/how-to-use-intel-ipp-s-1d-four...

ippi function is undefined

I am trying to use the function ippiFilterBoxBorder and i keep getting a compiler error of
Error    4    error : identifier "y8_ippiFilterBoxBorder_16u_C1R" is undefined   
Error    3    error : identifier "y8_ippiFilterBoxBorderGetBufferSize" is undefined

If i change the FilterBoxBorder function to FilterBox (which is deprecated) everything compiles and runs with no issue.
I am using the latest c++ Intel compiler 15.0.2.179 on windows

Any idea what am i doing wrong?
 

 

ippiTranspose crashing

Hi,

I am calling ippTranspose with the following parameters (and valid buffer pointers of course):

void *pSrc = <input buffer>;
void *pDst = <output buffer>;
int iWidth  = 640;
int iHeight = 480;
int iSrcStep = iWidth * 3;
int iDstStep = iHeight * 3;
int iSrcOffset = iSrcStep * (iHeight - 1);
int iSrcStepT  = -iSrcStep;
IppiSize sizeSrc = { iWidth, iHeight };
ippiTranspose_8u_C3R((Ipp8u*)pSrc + iSrcOffset, iSrcStepT, (Ipp8u*)pDst, iDstStep, sizeSrc);

It crashes here:

Create a LIB File from Intel IPP

Hello,

I'm using Visual Studio 2013 and the Intel IPP 8.2.

I have some Auxiliary Functions I build upon Intel IPP for image manipulation in C++ style by overloading some operators and defining function which are composition of many Intel IPP functions.

Now, I want to build a library of that functions I created and I want this library to be "Self Defined".
Namely, on my future projects I want to link to that library (And only that) and be able to use my functions (Which relies on Intel IPP).
Basically, it is something like the question here:
