We use four camera. The output image is normal, but why is it only concentrated in the upper left corner and the output screen cannot occupy the whole screen?

    Hi,

    Could you answer my below queries regarding the issue :

    1. Could you tell me which SDK are you using?

    2. Is this the multi-cam demo from SDK that you are trying to run or is it some other application?

    3. What is the resolution of the display that you are using? and what is the output resolution that is projected on the display?

    4. Are you trying to display the images from 4 cameras in a mosaic way?

    Regards,
    Nikhil

    Another question: how can I display 4 cameras in the mosaic way? Do I need to make some changes  in the code of the demo:'app_tidl_od_cam' inside dl_demos?

    Hi Ligen,

    Have you configured the mosaic node correctly? Could you please share your configuration and how the output is seen on the display currently?

    The demo "app_tidl_od_cam" already displays the images from the cameras in the mosaic way based on the number of cameras enabled.
