dm8168 DVRRDK_01.06.00.11 deinterlace scaler

We want run dual streaming on dm8168. We use deinterlace H and it can output 2 queues(DEI_LINK_OUT_QUE_DEI_SC and DEI_LINK_OUT_QUE_VIP_SC).
But we found the queue[DEI_LINK_OUT_QUE_VIP_S] can scale upto D1 but the queue[DEI_LINK_OUT_QUE_DEI_SC] just upto 4CIF.
Our problems:
(1) Whether dm8168 deinterlace H can support out queue[DEI_LINK_OUT_QUE_VIP_SC] queue[DEI_LINK_OUT_QUE_DEI_SC] both D1?
(2) Is this the problem of resource limitation of dm8168 capture scaler?

    I am not sure on how you got this inference. Both the queues can generate D1 output. Actually, the output of the DEIs are controlled in the application in the deiPrm. You can configure the absolute height and width or you can configure the scaling ratio.

    As i said above, there is no specific limitation of scalars which would cause such problem.

    Thanks for your reply Anshuman.

    Anshuman: I am not sure on how you got this inference.

    We use the links api as following:

    We exchange the encoder codec, and found that queue[DEI_LINK_OUT_QUE_DEI_SC] also can not upto D1.

    If the scaler is OK, did the nsf have the limition for the resolution of D1? Could you tell me the problem may exist in our media pipeline?

    We have checked. NSF link need set tilerEnable TRUE.
