/**
* Function: omxVCM4P10_DecodeChromaDcCoeffsToPairCAVLC
*
* Description:
* Performs CAVLC decoding and inverse raster scan for 2x2 block of
* ChromaDCLevel. The decoded coefficients in packed position-coefficient
* buffer are stored in increasing raster scan order, namely position order.
*
* Remarks:
*
* Parameters:
* [in] ppBitStream Double pointer to current byte in bit stream
* buffer
* [in] pOffset Pointer to current bit position in the byte
* pointed to by *ppBitStream
* [out] ppBitStream *ppBitStream is updated after each block is decoded
* [out] pOffset *pOffset is updated after each block is decoded
* [out] pNumCoeff Pointer to the number of nonzero coefficients
* in this block
* [out] ppPosCoefbuf Double pointer to destination residual
* coefficient-position pair buffer
*
* Return Value:
* Standard omxError result. See enumeration for possible result codes.
