| * Function: omxVCCOMM_SAD_16x (6.1.4.1.4) |
| * |
| * Description: |
| * This function calculates the SAD for 16x16 and 16x8 blocks. |
| * |
| * Input Arguments: |
| * |
| * pSrcOrg - Pointer to the original block; must be aligned on a 16-byte |
| * boundary. |
| * iStepOrg - Step of the original block buffer |
| * pSrcRef - Pointer to the reference block |
| * iStepRef - Step of the reference block buffer |
| * iHeight - Height of the block |
| * |
| * Output Arguments: |
| * |
| * pDstSAD - Pointer of result SAD |
| * |
| * Return Value: |
| * |
| * OMX_Sts_NoErr - no error |
| * OMX_Sts_BadArgErr - bad arguments. Returned if one or more of the |
| * following conditions is true: |
| * - at least one of the following pointers is NULL: |
| * pSrcOrg, pDstSAD, or pSrcRef |
| * - pSrcOrg is not 16-byte aligned. |
| * - iStepOrg <= 0 or iStepOrg is not a multiple of 16 |
| * - iStepRef <= 0 or iStepRef is not a multiple of 16 |
| * - iHeight is not 8 or 16 |
| * |
