-/**
- * Function: omxVCM4P2_BlockMatch_Half_16x16 (6.2.4.2.3)
- *
- * Description:
- * Performs a 16x16 block match with half-pixel resolution. Returns the
- * estimated motion vector and associated minimum SAD. This function
- * estimates the half-pixel motion vector by interpolating the integer
- * resolution motion vector referenced by the input parameter pSrcDstMV, i.e.,
- * the initial integer MV is generated externally. The input parameters
- * pSrcRefBuf and pSearchPointRefPos should be shifted by the winning MV of
- * 16x16 integer search prior to calling BlockMatch_Half_16x16. The function
- * BlockMatch_Integer_16x16 may be used for integer motion estimation.
- *
- * Input Arguments:
- *
- * pSrcRefBuf - pointer to the reference Y plane; points to the reference
- * macroblock that corresponds to the location of the current
- * macroblock in the current plane.
- * refWidth - width of the reference plane
- * pRefRect - reference plane valid region rectangle
- * pSrcCurrBuf - pointer to the current block in the current macroblock
- * buffer extracted from the original plane (linear array, 256
- * entries); must be aligned on a 16-byte boundary. The number of
- * bytes between lines (step) is 16.
- * pSearchPointRefPos - position of the starting point for half pixel
- * search (specified in terms of integer pixel units) in the
- * reference plane, i.e., the reference position pointed to by the
- * predicted motion vector.
- * rndVal - rounding control parameter: 0 - disabled; 1 - enabled.
- * pSrcDstMV - pointer to the initial MV estimate; typically generated
- * during a prior 16X16 integer search; specified in terms of
- * half-pixel units.
- *
- * Output Arguments:
- *
- * pSrcDstMV - pointer to estimated MV
- * pDstSAD - pointer to minimum SAD
- *
- * Return Value:
- *
- * OMX_Sts_NoErr - no error
- * OMX_Sts_BadArgErr - bad arguments. Returned if one of the following
- * conditions is true:
- * - at least one of the following pointers is NULL: pSrcRefBuf,
- * pRefRect, pSrcCurrBuff, pSearchPointRefPos, pSrcDstMV.
- * - pSrcCurrBuf is not 16-byte aligned, or
- *
