Code: picam2_qt5_global.py """ Python 3/PyQt5 + picamera2 List available cameras. Run picam2_qt5_.py base on user selection. """ from PyQt5.QtWidgets import (QComboBox, QMainWindow, QApplication, QWidget, QVBoxLayout, QLabel, QLineEdit, QPushButton) from PyQt5.QtCore import QProcess import sys from picamera2 import Picamera2 cameras_info = Picamera2.global_camera_info() num_of_cam = len(cameras_info) if num_of_cam == 0: print("No camera attached!
