Converting from pixel order YCbCr411 to BGR

Hi all,

I'm new to using the IPP library and  I'm having trouble converting from pixel order YCbCr411 data to BGR format.  From reading the documentation, I know that I first need to convert the pixel order to planar format first before calling the the library function ippiYCbCr411ToBGR_8u_P3C4R to convert planar YCbCr411 data to BGR format. I see that I can probably use the ippiCopy_8u_C3P3R call to convert my image buffer from pixel order to planar order. 

For example, is this the following the correct approach?

int pDstStep[3];
Ipp8u* pFirst = ippiMalloc_8u_C1(srcCols, srcRows, &pDstStep[0]);
Ipp8u* pSecond = ippiMalloc_8u_C1(srcCols/4, srcRows, &pDstStep[1]);
Ipp8u* pThird = ippiMalloc_8u_C1(srcCols/4, srcRows, &pDstStep[2]);

Ipp8u* pDst[3] = { pFirst, pSecond, pThird };

 ippiCopy_8u_C3P3R((Ipp8u*)pImageBuffer,
            pImageBufferStride,
            pDst,
            srcCols,
            imgSize);

// Convert from 3 plane YCbCr411 source image to BGR
ippiYCbCr411ToBGR_8u_P3C4R(const unsigned char**)(&pDst),
            pDstStep,
            pDestBuffer,
            destStride,
            imgSize,
            0);

Thanks!
