| /** |
| * Function: omxVCM4P10_InterpolateChroma, |
| * |
| * Description: |
| * Performs 1/8-pixel interpolation for inter chroma MB. |
| * |
| * Remarks: |
| * |
| * Parameters: |
| * [in] pSrc Pointer to the source reference frame buffer |
| * [in] srcStep Reference frame step in byte |
| * [in] dstStep Destination frame step in byte. Must be multiple of roi.width. |
| * [in] dx Fractional part of horizontal motion vector component |
| * in 1/8 pixel unit;valid in the range [0,7] |
| * [in] dy Fractional part of vertical motion vector component |
| * in 1/8 pixel unit;valid in the range [0,7] |
| * [in] roi Dimension of the interpolation region;the parameters roi.width and roi.height must |
| * be equal to either 2, 4, or 8. |
| * [out] pDst Pointer to the destination frame buffer. |
| * if roi.width==2, 2-byte alignment required |
| * if roi.width==4, 4-byte alignment required |
| * if roi.width==8, 8-byte alignment required |
| * |
| * Return Value: |
| * If the function runs without error, it returns OMX_Sts_NoErr. |
| * If one of the following cases occurs, the function returns OMX_Sts_BadArgErr: |
| * pSrc or pDst is NULL. |
| * srcStep or dstStep < 8. |
| * dx or dy is out of range [0-7]. |
| * roi.width or roi.height is out of range {2,4,8}. |
| * roi.width is equal to 2, but pDst is not 2-byte aligned. |
| * roi.width is equal to 4, but pDst is not 4-byte aligned. |
| * roi.width is equal to 8, but pDst is not 8 byte aligned. |
| * srcStep or dstStep is not a multiple of 8. |
