TDA2EG-17: (VSDK0307) About Nullsrc -> XXX -> Display_Grpx

Part Number: TDA2EG-17

Dear all,

I need overlay object (line,word and image) on panel

For some reason (Can Not Grpx_Prm )

For some reasons I can't modify grpxSrcLink_tsk.c and modify draw2d Api inside

So.....

I need use Nullsrc (ex. Ti logo) -> Display_Grpx  (need display_gprx)

But I know it's incompatible

So is there any way to do the convert  by some mothed ? like

Nullsrc (ex. Ti logo) -> XXX ->Display_Grpx

Any suggestions?

and how do I do it??

Thanks!!

    Dear TI Experts,

    Is there a way to the above question?

    By the way,

    I try Nullsrc (ex. Ti logo) -> DssWb ->Display_Grpx

    Although the program runs normally

    But the TI logo is not displayed

    This is my Wb prm setting , and VID2 is NULL (Fake) , Because I don't know how to setting this param

    =======================================

    /* DSS M2M WB link */
    pUcObj->DssM2mWbPrm.enableOut = TRUE;
    pUcObj->DssM2mWbPrm.inPipelines[0U] = DSSM2MWBLINK_DISPC_PIPE_VID2;
    pUcObj->DssM2mWbPrm.numInPipeLines = 1U;
    pUcObj->DssM2mWbPrm.wbInNode = DSSM2MWBLINK_DISPC_WB_IN_NODE_VID2;

    /* input pipeline parameters */
    pUcObj->DssM2mWbPrm.inPosX[0U] = 0U ;
    pUcObj->DssM2mWbPrm.inPosY[0U] = 0U ;
    pUcObj->DssM2mWbPrm.inTarWidth[0U] = 1280;
    pUcObj->DssM2mWbPrm.inTarHeight[0U] = 256;

    /* Output parameters */
    pUcObj->DssM2mWbPrm.outDataFmt= SYSTEM_DF_BGR16_565;
    pUcObj->DssM2mWbPrm.outWidth= 1280;
    pUcObj->DssM2mWbPrm.outHeight = 256;

    /* The overlay width and height are used only if 'wbInNode' is overlay node */
    pUcObj->DssM2mWbPrm.ovlyWidth = 1280;
    pUcObj->DssM2mWbPrm.ovlyHeight = 256;

    =======================================

    Is there any other suggests??

    Thanks!

    Dear all,

    Supplementary details

    And I have an other chains is

    IssCapture -> Display_M4  (use VID1 pipe)   vencId = LCD2 , outputPort = DPI2_OUTPUT

    and camera can currently be displayed on the panel

    I hope  chains:Nullsrc (ex. Ti logo) -> DssWb ->Display_Grpx    can  overlay VID1 pipe (Panel)

    Thanks!!
