count   Number of the last non-zero coefficient in zig-zag order. When a block contains no non-zero coefficients, the value is -1.
dstStep   Step of the destination array.
pDst   Pointer to a location in a destination buffer, a location in a destination array or to a destination result.
pSrc   Pointer to a block of DCT coefficients.


These functions step through a transposed 8X8 block of DCT coefficients in a source buffer, perform an IDCT based on the AAN algorithm, and write the result to a destination buffer.
