NullSrc Enable

Ravi,

    Null Src Link can be used to provide input to the next link.   This is used to integrate other links when capture link is not available. This is useful when capture link is not used but some input is needed for other links.

Below is the sample usage.

***********************************************************************************************************************************************************************

    nullSrcPrm.outQueParams.nextLink      = nextLinkId;
    nullSrcPrm.timerPeriod                = 33; /**< Time period at which Null/Dummy Output command has to be generated */
    nullSrcPrm.inputInfo.numCh            = 16;
    for(i=0; i<nullSrcPrm.inputInfo.numCh; i++)
    {
        System_LinkChInfo *pChInfo;

        pChInfo = &nullSrcPrm.inputInfo.chInfo[i];

        /* Configure each channel*/
        pChInfo->dataFormat = SYSTEM_DF_YUV420SP_UV;
        pChInfo->memType    = SYSTEM_MT_NONTILEDMEM;
        pChInfo->startX     = 48;
        pChInfo->startY     = 32;
        pChInfo->width      = 720;
        pChInfo->height     = 576;
        pChInfo->pitch[0]   = x;
        pChInfo->pitch[1]   = y;
        pChInfo->pitch[2]   = z;
        pChInfo->scanFormat = SYSTEM_SF_PROGRESSIVE;
    }
