TDA3XEVM: How can i display the 4-ch camera(CSI2) and 1-ch camera(VIP ) together in the same monitor?

Part Number: TDA3XEVM

Hi,

I'm looking for the solution to display with the 4-ch camera(CSI2) and the 1-ch camera(VIP) together in the same monitor.

For the 4-ch camera(CSI2), i use the DS90UB964,

and for the 1-ch camera(VIP), i use the DS90UB914.

How can i generate the application?

Is there the referenceable usecases in the PROCESSOR_SDK_VISION_03_00_00_00?

If you know about the solution or good idea, plz let me know.

Thanks.

    Hi Lee,

    As such, it is possible. But there is no usecase. We have usecases for capturing 4 channels over CSI2 and capture from VIP. but they are independent usecases. You could just merge them. it is possible

    Hi Brijesh

    As you said, I merged them (CSI-2 and VIP usecases).
    But, when i enable the blow source, the VIP camera only display in the monitor.
     When i disable the blow source, the CSI-2 camera only display.
    Currently, the VIP and CSI-2 didn't display in the same time.

    =========================================================
    ChainsCommon_StartCaptureDevice(
    CHAINS_CAPTURE_SRC_OV10635,
    pObj->captureOutWidth,
    pObj->captureOutHeight
    );
    =========================================================

    Hi Lee,

    How are you displaying both the camera to the display?
    You need to create some kind of mosaic image and include all five image into a single display image and then display it.
    Without this mosacing, it will just display image from one of the sources.

    Hi Brijesh,

    My application consist of below structure.

    ======================================================
    IssCapture -> Sync -> Alg_DmaSwMs -> Display_Video_1
    Capture -> Display_Video_2
    GrpxSrc -> Display_Grpx
    ======================================================

    The mosaic image meaning "Alg_DmaSwMs". Right?
    Could you suggest the application structure for CSI-2 and VIP?

    Regards,
    Lee

    Hi Lee,

    Yes, you will have to use DMASwMs, but before that you need to down scale images using either VPE or iss resizer to smaller resolutions.

    The flow would be like

    ISSCapture -> ISSResizer -> Merge - >Sync -> Alg_DmaSwMs -> Display
    Capture -> ISSResizer -> Merge

    You need to change parameters for resizer, merge, sync and dmaswms links in your usecase. This depends on how you want to display 5 channels in a single frame.
