;/**
; * Function: omxVCCOMM_Copy16x16
; *
; * Description:
; * Copies the reference 16x16 block to the current block.
; * Parameters:
; * [in] pSrc - pointer to the reference block in the source frame; must be aligned on an 16-byte boundary.
; * [in] step - distance between the starts of consecutive lines in the reference frame, in bytes;
; * must be a multiple of 16 and must be larger than or equal to 16.
; * [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 16-byte boundary: pSrc, pDst
; * - step <16 or step is not a multiple of 16.
