    \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

    \sa QCamera
