;/**
 ; * Function: omxVCCOMM_Copy8x8
 ; *
 ; * Description:
 ; * Copies the reference 8x8 block to the current block.
 ; * Parameters:
 ; * [in] pSrc         - pointer to the reference block in the source frame; must be aligned on an 8-byte boundary.
 ; * [in] step         - distance between the starts of consecutive lines in the reference frame, in bytes;
 ; *                     must be a multiple of 8 and must be larger than or equal to 8.
 ; * [out] pDst        - pointer to the destination block; must be aligned on an 8-byte boundary.
 ; * Return Value:
 ; * OMX_Sts_NoErr     - no error
 ; * OMX_Sts_BadArgErr - bad arguments; returned under any of the following conditions:
 ; *                   - one or more of the following pointers is NULL:  pSrc, pDst
 ; *                   - one or more of the following pointers is not aligned on an 8-byte boundary:  pSrc, pDst
 ; *                   - step <8 or step is not a multiple of 8.
