\class QMediaRecorderControl
\inmodule QtMultimedia
\ingroup multimedia_control
\brief The QMediaRecorderControl class provides access to the recording
functionality of a QMediaService.
Generally you will use the QMediaRecorder class in application code - this
class is mostly used when implementing a new QMediaService or if there is
access to specific low level functionality not otherwise present in QMediaRecorder.
If a QMediaService can record media it will implement QMediaRecorderControl.
This control provides a means to set the \l {outputLocation()}{output location},
and record, pause and stop recording via the \l setState() method. It also
provides feedback on the \l {duration()}{duration} of the recording.
The interface name of QMediaRecorderControl is \c org.qt-project.qt.mediarecordercontrol/5.0 as
defined in QMediaRecorderControl_iid.
\sa QMediaService::requestControl(), QMediaRecorder

\macro QMediaRecorderControl_iid
\c org.qt-project.qt.mediarecordercontrol/5.0
Defines the interface name of the QMediaRecorderControl class.

/*!
\fn QUrl QMediaRecorderControl::outputLocation() const
Returns the current output location being used.
*/
/*!
\fn bool QMediaRecorderControl::setOutputLocation(const QUrl &location)
Sets the output \a location and returns if this operation is successful.
If file at the output location already exists, it should be overwritten.
The \a location can be relative or empty;
in this case the service should use the system specific place and file naming scheme.
After recording has started, the backend should report the actual file location
with actualLocationChanged() signal.
*/

\fn QMediaRecorder::State QMediaRecorderControl::state() const
Return the current recording state.
*/

\fn QMediaRecorder::Status QMediaRecorderControl::status() const
Return the current recording status.
*/
/*!
\fn qint64 QMediaRecorderControl::duration() const
Return the current duration in milliseconds.
*/
/*!
\fn void QMediaRecorderControl::setState(QMediaRecorder::State state)
Set the media recorder \a state.
*/
/*!
\fn void QMediaRecorderControl::applySettings()
Commits the encoder settings and performs pre-initialization to reduce delays when recording
is started.
*/
/*!
\fn bool QMediaRecorderControl::isMuted() const
Returns true if the recorder is muted, and false if it is not.
*/
/*!
\fn void QMediaRecorderControl::setMuted(bool muted)
Sets the \a muted state of a media recorder.
*/
/*!
\fn qreal QMediaRecorderControl::volume() const
Returns the linear audio gain of media recorder.
*/
/*!
\fn void QMediaRecorderControl::setVolume(qreal gain)
Sets the linear audio \a gain of a media recorder.
*/
/*!
\fn void QMediaRecorderControl::stateChanged(QMediaRecorder::State state)
Signals that the \a state of a media recorder has changed.
*/
/*!
\fn void QMediaRecorderControl::statusChanged(QMediaRecorder::Status status)
Signals that the \a status of a media recorder has changed.
*/
/*!
\fn void QMediaRecorderControl::durationChanged(qint64 duration)
Signals that the \a duration of the recorded media has changed.
This only emitted when there is a discontinuous change in the duration such as being reset to 0.
*/
/*!
\fn void QMediaRecorderControl::mutedChanged(bool muted)
Signals that the \a muted state of a media recorder has changed.
*/
/*!
\fn void QMediaRecorderControl::volumeChanged(qreal gain)
Signals that the audio \a gain value has changed.
*/
/*!
\fn void QMediaRecorderControl::actualLocationChanged(const QUrl &location)
Signals that the actual media \a location has changed.
This signal should be emitted at start of recording.
*/
/*!
\fn void QMediaRecorderControl::error(int error, const QString &errorString)
Signals that an \a error has occurred. The \a errorString describes the error.
