Hello Jason, I don't know if this helps you, but inside the examples that comes with PySide2 you can find one related to QCamera: https://code.qt.io/cgit/pyside/pyside-setup.git/tree/examples/multimedia/camera.py At least locally (I don't have a camera) I can access to that method through QCameraInfo: >>> from PySide2.QtMultimedia import QCameraInfo >>> QCameraInfo.availableCameras() [] let us know how it goes!
