question about the rotation and tiler

Hi,

I want to realize the 90-degree, 180-degree and 270-degree rotated used tiler.

I create the link as follow:

capture->dup->dei->framesout-> ...

At dupLink, I copy the non-tiler memory to tiler memory by edma transfer.

At deiLink, I translate the tiler-address and realize the tiler memory to non-tiler memory and rotation.

I modify the deiLink input frame as follow:

#define UTILS_TILER_CNT_8BIT_PITCH_XY_SWAP  (8192)

#define UTILS_TILER_CNT_16BIT_PITCH_XY_SWAP (8192)

switch(rotationView)

{
case AVAL_ROTATION_90_DEGREE:
    pInFrame->addr[0][0] = (Ptr)Utils_tilerGetOriAddr((UInt32)pInFrame->addr[0][0], UTILS_TILER_CNT_8BIT, 6, width, height);
    pInFrame->addr[0][1] = (Ptr)Utils_tilerGetOriAddr((UInt32)pInFrame->addr[0][1], UTILS_TILER_CNT_16BIT, 6, width, height/2);
    pInFrameInfo->rtChInfo.width = height;
    pInFrameInfo->rtChInfo.height = width;
    pInFrameInfo->rtChInfo.pitch[0] = UTILS_TILER_CNT_8BIT_PITCH_XY_SWAP;
    pInFrameInfo->rtChInfo.pitch[1] = UTILS_TILER_CNT_16BIT_PITCH_XY_SWAP;
break;

case AVAL_ROTATION_180_DEGREE:
    pInFrame->addr[0][0] = (Ptr)Utils_tilerGetOriAddr((UInt32)pInFrame->addr[0][0], UTILS_TILER_CNT_8BIT, 3, width, height);
    pInFrame->addr[0][1] = (Ptr)Utils_tilerGetOriAddr((UInt32)pInFrame->addr[0][1], UTILS_TILER_CNT_16BIT, 3, width, height/2);
break;

case AVAL_ROTATION_270_DEGREE:
    pInFrame->addr[0][0] = (Ptr)Utils_tilerGetOriAddr((UInt32)pInFrame->addr[0][0], UTILS_TILER_CNT_8BIT, 5, width, height);
    pInFrame->addr[0][1] = (Ptr)Utils_tilerGetOriAddr((UInt32)pInFrame->addr[0][1], UTILS_TILER_CNT_16BIT, 5, width, height/2);
    pInFrameInfo->rtChInfo.width = height;
    pInFrameInfo->rtChInfo.height = width;
    pInFrameInfo->rtChInfo.pitch[0] = UTILS_TILER_CNT_8BIT_PITCH_XY_SWAP;
    pInFrameInfo->rtChInfo.pitch[1] = UTILS_TILER_CNT_16BIT_PITCH_XY_SWAP;
    break;
    default:
    Vps_printf("DEI_DEBUG: %s, Line%d, don't support the rotation view!\n", __func__, __LINE__);
    return -1;
}

And modify the function Utils_tilerGetOriAddr() as follow:

UInt32 Utils_tilerGetOriAddr(UInt32 tilerAddr,  UInt32 cntMode,

                                                   UInt32 oriFlag, UInt32 width, UInt32 height)
{
    UInt32 oriAddr;
    UInt32 hOffset, vOffset;
    UInt32 hStride, vStride;

    /* Get the base address without orientation and container modes */
    oriAddr = tilerAddr;
    oriAddr &= ~(0x1Fu << 27u);
    oriFlag &= (UTILS_TILER_ORI_X_FLIP |
    UTILS_TILER_ORI_Y_FLIP | UTILS_TILER_ORI_XY_SWAP);

    /* Figure out horizontal stride and max lines as per container mode */
    if (UTILS_TILER_CNT_8BIT == cntMode)
   {
       hStride = VPSUTILS_TILER_CNT_8BIT_PITCH;
       vStride = UTILS_TILER_CNT_8BIT_MAX_LINES;
   }
   else if (UTILS_TILER_CNT_16BIT == cntMode)
   {
        hStride = VPSUTILS_TILER_CNT_16BIT_PITCH;
        vStride = UTILS_TILER_CNT_16BIT_MAX_LINES; 
   }
    else
    {
         hStride = VPSUTILS_TILER_CNT_32BIT_PITCH;
         vStride = UTILS_TILER_CNT_32BIT_MAX_LINES;
    }

    hOffset = oriAddr & (hStride - 1u);
    vOffset = (oriAddr / hStride);
    switch (oriFlag) {
        case 5:
               UTILS_assert((hStride > (hOffset + width)));
               oriAddr = (hStride - (hOffset + width - 1)) * vStride;
               oriAddr += vOffset;
               break;
        case 6:
               oriAddr = hOffset * vStride;
               UTILS_assert(vStride > (vOffset + height));
               oriAddr += vStride - (vOffset + height);
               break;
        default:
        break;
    }

    /* Set the orientation modes */
    oriAddr &= ~UTILS_TILER_ORI_MODE_MASK;
    oriAddr |= (oriFlag << UTILS_TILER_ORI_MODE_SHIFT);

    /* Set the container mode */
    oriAddr = UTILS_TILER_PUT_CNT_MODE(oriAddr, cntMode);

    return (oriAddr);
}

The 180-degree rotation is succeed, however, the 90-degree and 270-degree rotation as follow:

270-degree rotation image as follow:

Could you give me some advices?
