\class QCameraInfo
\brief The QCameraInfo class provides general information about camera devices.
\since 5.3
\inmodule QtMultimedia
\ingroup multimedia
\ingroup multimedia_camera
QCameraInfo lets you query for camera devices that are currently available on the system.
The static functions defaultCamera() and availableCameras() provide you a list of all
available cameras.
This example prints the name of all available cameras:
\snippet multimedia-snippets/camera.cpp Camera listing
A QCameraInfo can be used to construct a QCamera. The following example instantiates a QCamera
whose camera device is named 'mycamera':
\snippet multimedia-snippets/camera.cpp Camera selection
You can also use QCameraInfo to get general information about a camera device such as
description, physical position on the system, or camera sensor orientation.
\snippet multimedia-snippets/camera.cpp Camera info
