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. \sa QMediaRecorder, QVideoEncoderSettings, QMediaService::requestControl() */ /*! \macro QVideoEncoderControl_iid \c com.nokia.Qt.QVideoEncoderControl/1.0 Defines the interface name of the QVideoEncoderControl class. \relates QVideoEncoderControl */ /*!
