| FwStatus | fwiDequantTransformResidual_H264_16s_C1I | ( | Fw16s * pSrcDst, Fw32s step, Fw16s * pDC, Fw32s AC, Fw32s QP ); |
| AC | AC compoment | |
| QP | Quantizer scale factor read from the bitstream. | |
| pDC | Pointer to an output coefficient. | |
| pSrcDst | Pointer to the start of the block. | |
| step | Plane step |
This function steps through a source buffer, performs scaling, inverse transformation, and shift of a residual 4X4 block in accordance with JVTG050 8.5.7., and writes the result back to the source buffer.
For chroma block transforms, call this function after TransformDequantChromaDC_H264.
