[DM8148] Can driving ISS and VPSS at the same time

 Dear Sirs,

We are developing a video conference product on DM8148.

we need to drive Camera interface as video input, and HDMI-out as video output at the same time.

We have studied VC demo code which contains VPSS to drive HDMI-out only and IPNC demo code which contains ISS to drive camera-in only.

Can  ISS (for camera interface) and VPSS (for HDMI-out) be driven simultaneously?

Is there any sample code?

Thank you.

    Yes they can both be functional at the same time.

    In fact, you could also use the VPSS for camera capture too, depending on your camera/capture device. (As shown in the VC demo I believe, which uses HDMI capture and HDMI display if I am not mistaken)

    I don't know too much about the software side, but it should be fairly straight forward to merge the two demos you mentioned , replacing the VC capture code with the IPNC capture code since the frame works can run at the same time.

    BR,

    Thank your response.
    Our camera is parallel bus camera module, so we use ISS.
    We are trying to merge the VC and IPNC as you mentioned.
    Is there any reference code about it?

    Hi,

    I think there is some code for ISS interface.This is but not a part of ezsdk release. So you can contact your local FAE for same for gettting some code on ISS.

    Hi,

    We have IPNC demo(IPNC/Alpha_Release_0.5.0) now. 

    Is there any other sample about the "driving ISS+ VPSS" ?
