Hi 

i have a issue about image quality issue(line is blocked ) .  i guess this is a lowcostScaling issue. 

but lowcostscaling is setted FALSE. i tested this dvr_rdk_demo_mcfw(RDK_03.50) , progressive mode, HDMI xga resolution. 

i checked console log . 

7536.201301241812.txt

i have more images but upload two images (the same monitor)

do you know why image quality is more not good?

1.  DVRRDK_03.50.xx ( fluorescent light line is blocked)

2. DVRRDK_03.00 (fluorescent light line is smooth)

 

Best Regards.

    Are you seeing the quality issue with all layouts or only 4x4 layout.

    Hi,

    log file is captured data at the moment when i see that issue. 

    and LAYOUT_4CH is not shown that issue.

    Are you seeing the saw tooth edge when commenting out

    /dvr_rdk/mcfw/src_linux/mcfw_api/usecases/ti816x/multich_progressive_vcap_venc_vdec_vdis.c

    gVdisModuleContext.setMosaicFxn     = MultiCh_progressiveDVRSetMosaicParams;

    also ?

    Another thing is are you seeing the artifacts for all channels .Mainly is there difference between channel 0 -7 and channel 8 - 15 ?

    One more test is change /dvr_rdk/mcfw/src_bios6/links_m3vpss/swMs/swMsLink_drv.c

    Int32 SwMsLink_drvSetScCoeffs(SwMsLink_Obj * pObj, FVID2_Handle fvidHandle,
                    UInt32 curCoeffId_v, UInt32 curCoeffId_h, Bool isDei)
    {
        Int32 retVal = FVID2_SOK;
        Vps_ScCoeffParams coeffPrms;
        static char *scCoeffName[VPS_SC_SET_MAX] =
        {
            "3/16",
            "4/16",
            "5/16",
            "6/16",
            "7/16",
            "8/16",
            "9/16",
            "10/16",
            "11/16",
            "12/16",
            "13/16",
            "14/16",
            "15/16",
            "UPSCALE",
            "1/1",
        };

        //if(curCoeffId_h>=VPS_SC_SET_MAX) -- FORCE TO UPSCALE
            curCoeffId_h = VPS_SC_US_SET;

        //if(curCoeffId_v>=VPS_SC_SET_MAX) -- FORCE TO UPSCALE
            curCoeffId_v = VPS_SC_US_SET;

    Hi.

    Thank you for your reply. i checked two things. but there's nothing changed. 

    i wondering you can not see this issue? this issue seen only for me?

    1. 

    //gVdisModuleContext.setMosaicFxn     = MultiCh_progressiveDVRSetMosaicParams;

    2. One more test is change /dvr_rdk/mcfw/src_bios6/links_m3vpss/swMs/swMsLink_drv.c
