Issue with DEI in interlaced bypass mode

I use DEI link in interlaced bypass mode to scale down a 1080i capture before encoding.

When I encode the original 1080i capture, all is fine (see first snapshot) , but when I encode the DEI downscaled frames, one field ends up with an offset (see snapshot 2).  You will have too zoom on second snapshot to see that one field is not display where it should.

Is there any patch to fix this issue.

Thanks for support

Yann

Here are the settings I set for the DEI link

    deiPrm.inQueParams.prevLinkId   = dupId;
    deiPrm.inQueParams.prevLinkQueId= 1;
    deiPrm.outQueParams[DEI_LINK_OUT_QUE_DEI_SC].nextLink = nsfId;
    deiPrm.enableOut[DEI_LINK_OUT_QUE_DEI_SC] = TRUE;
    deiPrm.inputFrameRate[DEI_LINK_OUT_QUE_DEI_SC] = 60;
    deiPrm.outputFrameRate[DEI_LINK_OUT_QUE_DEI_SC] = 60;
    deiPrm.enableDeiForceBypass  = TRUE;
    deiPrm.enableForceInterlacedInput = FALSE;
    deiPrm.interlacedBypassMode = TRUE;
    deiPrm.enableLineSkipSc = FALSE;
    deiPrm.inputDeiFrameRate = 60;
    deiPrm.outputDeiFrameRate = 60;
    deiPrm.enableInputFrameRateUpscale = FALSE;

    
    deiPrm.outScaleFactor[DEI_LINK_OUT_QUE_DEI_SC][0].scaleMode = DEI_SCALE_MODE_ABSOLUTE;
    deiPrm.outScaleFactor[DEI_LINK_OUT_QUE_DEI_SC][0].absoluteResolution.outWidth = 1440;
    deiPrm.outScaleFactor[DEI_LINK_OUT_QUE_DEI_SC][0].absoluteResolution.outHeight = 540;

    It looks like there is some weird unwanted video processing being done, even though the DEI is in bypass mode.

    Anything to suggest ?

    Hi Lletiernn,

    Can you please share the input yuv so that I can check at my end?

    Regards,

    Hi Yann,
    Sorry for delayed response. I analyzed the register dump, DEI is used in bypass mode only as per your setting. Also I am not expecting any more issues with DEI. Scalar is used in progressive to progressive mode? Are you giving fields separately to the DEI driver or given as progressive frame? Can you please share register dump of scalar also.
    Regards,Murali

    Issue is coming from scaler.
    The parameters set in vpshal_sc.c scCalVertPolyphaseParams() are invalid for interlaced to interlaced mode. I also suspect wrong parameters for progressive to interlaced mode.

    I do not see the above issue when I use the progressive to progressive parameters, even though my video is interlaced to interlaced.

    Note that Im using interlaced with separate field.

    Hi Yann,
    I recommend you to use progressive to progressive mode of scalar for separate field scaling also. Please let me know if you have any other concerns.
