\brief The QVideoEncoderControl class provides access to the settings
of a media service that performs video encoding.
If a QMediaService supports encoding video data it will implement
QVideoEncoderControl. This control provides information about the limits
of restricted video encoder options and allows the selection of a set of
video encoder settings as specified in a QVideoEncoderSettings object.
The functionality provided by this control is exposed to application code
through the QMediaRecorder class.
The interface name of QVideoEncoderControl is \c com.nokia.Qt.QVideoEncoderControl/1.0 as
defined in QVideoEncoderControl_iid.
