Cable Extension Kit libcamera-apps No Output

  1. Where did you get the camera module(s)?
    Arducam shop

  2. Model number of the product(s).

    • SKU: B0386 (16MP IMX519 NOIR)
    • SKU: U6248 (15m extension kit)
  3. What hardware/platform were you working on?
    Tested on both Pi 3B and Pi 4B

  4. Instructions you have followed. (link/manual/etc.)

  5. Problems you were having.
    When the camera is connected directly to the Pi 3&4, it is able to function properly by taking pictures & videos. But after connecting it to through the 15M cable extension kit, the libcamera-apps output is a blank screen with no fps.

  6. The dmesg log from your hardware.
