[BUG] Unable to open both cameras

[dleporis]

Describe the issue I am getting the following when running $ python3 dual_camera.py:

Error: Unable to open both cameras

What version of L4T/JetPack System info (I got it using JetsonUtilities https://jetsonhacks.com/2017/08/28/quick-tip-which-version-of-l4t-is-running-nvidia-jetson-development-kit/) command $ python jetsonInfo.py: NVIDIA NVIDIA Jetson Nano Developer Kit L4T 32.7.2 [ JetPack 4.6.2 ] Ubuntu 18.04.6 LTS Kernel Version: 4.9.253-tegra CUDA NOT_INSTALLED CUDA Architecture: 5.3 OpenCV version: NOT_INSTALLED OpenCV Cuda: NO CUDNN: NOT_INSTALLED TensorRT: NOT_INSTALLED Vision Works: NOT_INSTALLED VPI: NOT_INSTALLED Vulcan: 1.2.70

What version of OpenCV 4.6.0

I got this by running:

$ python3
>>> import cv2
>>> print(cv2.__version__)

(Strange that JetsonUtilities didn't recognise it being installed)

Python Version 3.6.9

To Reproduce Run: $ cd CSI-Camera-master $ python3 dual_camera.py

Expected behavior I expected that feeds from both MIPI CSI cameras will show up on the monitor at the same time, and run until I press ^C
