\brief The QAudioDecoderControl class provides access to the audio decoding
functionality of a QMediaService.
\preliminary
The functionality provided by this control is exposed to application
code through the QAudioDecoder class.
The interface name of QAudioDecoderControl is \c com.nokia.Qt.QAudioDecoderControl/1.0 as
defined in QAudioDecoderControl_iid.
\sa QMediaService::requestControl(), QAudioDecoder
*/
/*!
\macro QAudioDecoderControl_iid
\c com.nokia.Qt.QAudioDecoderControl/1.0
Defines the interface name of the QAudioDecoderControl class.
\relates QAudioDecoderControl
*/
/*!
Destroys an audio decoder control.
*/
QAudioDecoderControl::~QAudioDecoderControl()
{
}
/*!
Constructs a new audio decoder control with the given \a parent.
*/

{
}
/*!
\fn QAudioDecoderControl::state() const
Returns the state of a player control.
*/
/*!
\fn QAudioDecoderControl::stateChanged(QAudioDecoder::State state)
Signals that the \a state of a player control has changed.
\sa state()
*/
/*!
\fn QAudioDecoderControl::sourceFilename() const
Returns the current media source filename, or a null QString if none (or a device)
*/
/*!
\fn QAudioDecoderControl::setSourceFilename(const QString &fileName)
Sets the current source to \a fileName. Changing the source will
stop any current decoding and discard any buffers.
Sources are exclusive, so only one can be set.
*/
/*!
\fn QAudioDecoderControl::sourceDevice() const
Returns the current media source QIODevice, or 0 if none (or a file).
*/
/*!
\fn QAudioDecoderControl::setSourceDevice(QIODevice *device)
Sets the current source to \a device. Changing the source will
stop any current decoding and discard any buffers.
Sources are exclusive, so only one can be set.

\fn QAudioDecoderControl::start()
Starts decoding the current media.
If successful the player control will immediately enter the \l {QAudioDecoder::DecodingState}
{decoding} state.

/*!
\fn QAudioDecoderControl::stop()
Stops playback of the current media and discards any buffers.
If successful the player control will immediately enter the \l {QAudioDecoder::StoppedState}
{stopped} state.
*/
/*!
\fn QAudioDecoderControl::error(int error, const QString &errorString)
Signals that an \a error has occurred. The \a errorString provides a more detailed explanation.
*/
/*!
\fn QAudioDecoderControl::bufferAvailableChanged(bool available)
Signals that the bufferAvailable property has changed to \a available.
*/
/*!
\fn QAudioDecoderControl::bufferReady()
Signals that a new buffer is ready for reading.
*/
/*!
\fn QAudioDecoderControl::formatChanged(const QAudioFormat &format)
Signals that the current audio format of the decoder has changed to \a format.
\sa audioFormat(), setAudioFormat
*/
/*!
\fn QAudioDecoderControl::audioFormat()
Returns the current audio format of the decoded stream.
Any buffers returned should have this format.
\sa setAudioFormat, audioFormatChanged
*/
/*!
\fn QAudioDecoderControl::setAudioFormat(const QAudioFormat &format)
Set the desired audio format for decoded samples to \a format.
If the decoder does not support this format, \l error() will
be set to \c FormatError.
If you do not specify a format, the format of the decoded
audio itself will be used. Otherwise, some format conversion
will be applied.
If you wish to reset the decoded format to that of the original
audio file, you can specify an invalid \a format.
