    hi Eason,

         I need to use DVRRDK 4.1 to prove that. After running the application below

    =========

    Main Menu

    =========

    1: 4CH VCAP + VENC + VDEC + VDIS - Progressive SD Encode + Decode

    2: 8CH <D1+CIF> VCAP + VENC + VDEC + VDIS - Progressive SD Encode + Decode

    3: 16CH RT VCAP + VENC + VDEC + VDIS - Progressive SD Encode + Decode

    4: 16CH NRT <D1+CIF> VCAP + VENC + VDEC + VDIS - Progressive SD Encode + Decode

    5: VDEC + VDIS - SD/HD Decode ONLY

    I use "case 2" for the beginning, I want to remove the path of 8xD1 MJPG. So I modify the code as below

    in multich_progressive_8ch_vcap_venc_vdec_vdis.c

    /*************** MJPEG DEI1_VIP1_SC Settings ******************************/
    set_DEI_BYPASS_VIP1_SC_MJPEG_params(
    &deiPrm[DEI_BYPASS_VIP1_SC_FOR_MJPEG],
    dupId[CAPTURE_DUP_LINK_IDX],
    3,
    SYSTEM_LINK_ID_INVALID,
    mergeId[D1_CIF_QCIF_MERGE_LINK_IDX]);  => SYSTEM_LINK_ID_INVALID);

    /* CH0..7 - D1 FOR MJPEG */

    mergePrm[D1_CIF_QCIF_MERGE_LINK_IDX].inQueParams[2].prevLinkId =
    gVcapModuleContext.deiId[DEI_BYPASS_VIP1_SC_FOR_MJPEG];  ==> SYSTEM_LINK_ID_INVALID;


    //gVcapModuleContext.nsfId[NSF_AFTER_SCALAR_LINK];
    mergePrm[D1_CIF_QCIF_MERGE_LINK_IDX].inQueParams[2].prevLinkQueId =
    DEI_LINK_OUT_QUE_VIP_SC;  ==> 0;

    mergePrm[D1_CIF_QCIF_MERGE_LINK_IDX].notifyNextLink = TRUE;
    mergePrm[D1_CIF_QCIF_MERGE_LINK_IDX].numInQue = 3;    ==> 2

    and I got following messages

    [m3vpss ] CAPTURE : Capture FPS: 0.0 fps ... in 4294952.7 secs
    [m3vpss ] 14691: Assertion @ Line: 61 in links_common/system/system_linkApi.c: procId < SYSTEM_PROC_MAX : failed !!!

    Please help me that~ thanks
