| /** |
| * Function: omxVCM4P10_DeblockLuma_I |
| * |
| * Description: |
| * This function performs deblock filtering the horizontal and vertical edges of a luma macroblock |
| *(16x16). |
| * |
| * Remarks: |
| * |
| * Parameters: |
| * [in] pSrcDst pointer to the input macroblock. Must be 8-byte aligned. |
| * [in] srcdstStep image width |
| * [in] pAlpha pointer to a 2x2 table of alpha thresholds, organized as follows: { external |
| * vertical edge, internal vertical edge, external horizontal |
| * edge, internal horizontal edge } |
| * [in] pBeta pointer to a 2x2 table of beta thresholds, organized as follows: { external |
| * vertical edge, internal vertical edge, external horizontal edge, |
| * internal horizontal edge } |
| * [in] pThresholds pointer to a 16x2 table of threshold (TC0), organized as follows: { values for |
| * the left or above edge of each 4x4 block, arranged in vertical block order |
| * and then in horizontal block order) |
| * [in] pBS pointer to a 16x2 table of BS parameters arranged in scan block order for vertical edges and then horizontal edges; |
| * valid in the range [0,4] with the following restrictions: i) pBS[i]== 4 may occur only for 0<=i<=3, ii) pBS[i]== 4 if and only if pBS[i^1]== 4. Must be 4-byte aligned. |
| * [out] pSrcDst pointer to filtered output macroblock. |
| * |
| * Return Value: |
| * OMX_Sts_NoErr - no error |
| * OMX_Sts_BadArgErr - bad arguments |
| * - Either of the pointers in pSrcDst, pAlpha, pBeta, pTresholds or pBS is NULL. |
| * - pSrcDst is not 8-byte aligned. |
| * - srcdstStep is not a multiple of 8 |
| * - pBS is out of range, i.e., one of the following conditions is true: pBS[i]<0, pBS[i]>4, pBS[i]==4 for i>=4, or (pBS[i]==4 && pBS[i^1]!=4) for 0<=i<=3. |
