now i do some compare test.
i construct the link like cap->swms->dis
and cap->scalar->swms->dis
so if i add the scalar link ,the image quality will be a little worse ,so why? and how can i fix it?
the below is my scalar link parameters
SclrLink_CreateParams sclrPrm;
SclrLink_CreateParams_Init(&sclrPrm);
sclrPrm.inQueParams.prevLinkId = gVcapModuleContext.captureId;
sclrPrm.inQueParams.prevLinkQueId = 0;
sclrPrm.outQueParams.nextLink = gVdisModuleContext.displayId[0];
sclrPrm.tilerEnable = FALSE;
sclrPrm.enableLineSkipSc = FALSE;
sclrPrm.inputFrameRate = 60;
sclrPrm.outputFrameRate = 60;
sclrPrm.outScaleFactor.ratio.widthRatio.numerator = 1;
sclrPrm.outScaleFactor.ratio.widthRatio.denominator = 1;
sclrPrm.outScaleFactor.ratio.heightRatio.numerator = 1;
sclrPrm.outScaleFactor.ratio.heightRatio.denominator = 1;
sclrPrm.numBufsPerCh = 2;
the following is the log:
