-/**
- * Function:  omxVCM4P10_TransformDequantChromaDCFromPair   (6.3.4.2.2)
- *
- * Description:
- * Reconstruct the 2x2 ChromaDC block from coefficient-position pair buffer, 
- * perform integer inverse transformation, and dequantization for 2x2 chroma 
- * DC coefficients, and update the pair buffer pointer to next non-empty 
- * block. 
- *
- * Input Arguments:
- *   
- *   ppSrc - Double pointer to residual coefficient-position pair buffer 
- *            output by CALVC decoding 
- *   QP - Quantization parameter QpC 
- *
- * Output Arguments:
- *   
- *   ppSrc - *ppSrc is updated to the start of next non empty block 
- *   pDst - Pointer to the reconstructed 2x2 ChromaDC coefficients buffer; 
- *            must be aligned on a 4-byte boundary. 
- *
- * Return Value:
- *    OMX_Sts_NoErr, if the function runs without error.
- *    OMX_Sts_BadArgErr - bad arguments: if one of the following cases occurs: 
- *    -    ppSrc or pDst is NULL. 
- *    -    pDst is not 4-byte aligned. 
- *    -    QP is not in the range of [0-51].
