Property Documentation

[read-only] availableCameras : list<object>

This property provides information about the cameras available on the system.

Each object in the list has the following properties:

Note: This property is static; it is not updated when cameras are added or removed from the system, like USB cameras on a desktop platform.

The following example shows how to display a list of available cameras. The user can change the active camera by selecting one of the items in the list.

Item {

    Camera {
        id: camera
    }

    VideoOutput {
        anchors.fill: parent
        source: camera
    }

    ListView {
        anchors.fill: parent

        model: QtMultimedia.availableCameras
        delegate: Text {
            text: modelData.displayName

            MouseArea {
                anchors.fill: parent
                onClicked: camera.deviceId = modelData.deviceId
            }
        }
    }
}

[read-only] defaultCamera : object

The defaultCamera object provides information about the default camera on the system.

Its properties are deviceId, displayName, position and orientation. See availableCameras for a description of each of them.

If there is no default camera, defaultCamera.deviceId will contain an empty string.

Note: This property is static; it is not updated if the system's default camera changes after the application started.
