| ; * 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. |
