hi all ,i found that 

if i set the below

vdMosaicParam->useLowCostScaling[winId] = 0;

the image display effect is better than the vdMosaicParam->useLowCostScaling[winId] = 1;

so why?

    Enabling low cost scaling will cause the scaler to skip alternate input lines and it is expected to cause lower quality. It is meant to be used for 4x4 layout type of configuration where each window resolution is small and skipping alternate input lines will not result in noticeable quality degradation.
