| countU | Number of the last non-zero U coefficient in zig-zag order. When a block contains no non-zero coefficients, the value is -1. | |
| countV | Number of the last non-zero V coefficient in zig-zag order. When a block contains no non-zero coefficients, the value is -1. | |
| dstStep | Step of the destination array. | |
| pDstUV | Pointer to a UV destination array. | |
| pSrcU | Pointer to a block of DCT coefficients for U component. | |
| pSrcV | Pointer to a block of DCT coefficients for V component. |
These functions step through transposed 8X8 U and V block of DCT coefficients in two source buffers, perform an IDCT based on the AAN algorithm, and write the result to a joined UV block in a sestination buffer.
