-/**
- * Function: omxVCM4P10_BlockMatch_Integer (6.3.5.2.1)
- *
- * Description:
- * Performs integer block match. Returns best MV and associated cost.
- *
- * Input Arguments:
- *
- * pSrcOrgY - Pointer to the top-left corner of the current block. If
- * iBlockWidth==4, 4-byte alignment required. If iBlockWidth==8,
- * 8-byte alignment required. If iBlockWidth==16, 16-byte alignment
- * required.
- * pSrcRefY - Pointer to the top-left corner of the co-located block in the
- * reference picture. If iBlockWidth==4, 4-byte alignment
- * required. If iBlockWidth==8, 8-byte alignment required. If
- * iBlockWidth==16, 16-byte alignment required.
- * nSrcOrgStep - Stride of the original picture plane, expressed in terms
- * of integer pixels; must be a multiple of iBlockWidth.
- * nSrcRefStep - Stride of the reference picture plane, expressed in terms
- * of integer pixels
- * pRefRect - pointer to the valid reference rectangle inside the reference
- * picture plane
- * nCurrPointPos - position of the current block in the current plane
- * iBlockWidth - Width of the current block, expressed in terms of integer
- * pixels; must be equal to either 4, 8, or 16.
- * iBlockHeight - Height of the current block, expressed in terms of
- * integer pixels; must be equal to either 4, 8, or 16.
- * nLamda - Lamda factor; used to compute motion cost
- * pMVPred - Predicted MV; used to compute motion cost, expressed in terms
- * of 1/4-pel units
- * pMVCandidate - Candidate MV; used to initialize the motion search,
- * expressed in terms of integer pixels
- * pMESpec - pointer to the ME specification structure
- *
- * Output Arguments:
- *
- * pDstBestMV - Best MV resulting from integer search, expressed in terms
- * of 1/4-pel units
- * pBestCost - Motion cost associated with the best MV; computed as
- * SAD+Lamda*BitsUsedByMV
- *
- * Return Value:
- * OMX_Sts_NoErr, if the function runs without error.
- * OMX_Sts_BadArgErr - bad arguments: if one of the following cases occurs:
- * - any of the following poitners are NULL:
- * pSrcOrgY, pSrcRefY, pRefRect, pMVPred, pMVCandidate, or pMESpec.
- * - Either iBlockWidth or iBlockHeight are values other than 4, 8, or 16.
- * - Any alignment restrictions are violated
- *
