| pDst | Pointer to a location in a destination buffer. | |

| pSrc | Pointer to a location in a source buffer. | |
| srcStep | Source buffer step size (width of the buffer in bytes). |
This function reads an 8X8 data block of 8-bit unsigned data in a source buffer, level-shifts the unsigned values to signed values, performs forward DCT and quantization, then writes the output data block to a destination buffer.
