QAudioEncoderControl Class Reference

Member Function Documentation

QAudioEncoderControl::QAudioEncoderControl ( QObject * parent = 0 ) [protected]

Create a new audio encode control object with the given parent.

QAudioEncoderControl::~QAudioEncoderControl () [virtual]

Destroys the audio encode control.

QAudioEncoderSettings QAudioEncoderControl::audioSettings () const [pure virtual]

Returns the audio encoder settings.

The returned value may be different tha passed to QAudioEncoderControl::setAudioSettings() if the settings contains the default or undefined parameters. In this case if the undefined parameters are already resolved, they should be returned.

This function was introduced in Qt Mobility 1.0.

See also setAudioSettings().

QString QAudioEncoderControl::codecDescription ( const QString & codec ) const [pure virtual]

Returns description of audio codec.

This function was introduced in Qt Mobility 1.0.

QVariant QAudioEncoderControl::encodingOption ( const QString & codec, const QString & option ) const [pure virtual]

Returns the value of audio encoding option for codec.

This function was introduced in Qt Mobility 1.0.

See also setEncodingOption().

void QAudioEncoderControl::setAudioSettings ( const QAudioEncoderSettings & settings ) [pure virtual]

Sets the selected audio settings.

This function was introduced in Qt Mobility 1.0.

See also audioSettings().

void QAudioEncoderControl::setEncodingOption ( const QString & codec, const QString & option, const QVariant & value ) [pure virtual]

Set the codec specific option to value.

This function was introduced in Qt Mobility 1.0.

See also encodingOption().

QStringList QAudioEncoderControl::supportedAudioCodecs () const [pure virtual]

Returns the list of supported audio codec names.

This function was introduced in Qt Mobility 1.0.

QStringList QAudioEncoderControl::supportedEncodingOptions ( const QString & codec ) const [pure virtual]

Returns the list of codec specific audio encoding options.

This function was introduced in Qt Mobility 1.0.

QList<int> QAudioEncoderControl::supportedSampleRates ( const QAudioEncoderSettings & settings, bool * continuous = 0 ) const [pure virtual]

Returns the list of supported audio sample rates, if known.

If non null audio settings parameter is passed, the returned list is reduced to sample rates supported with partial settings applied.

It can be used for example to query the list of sample rates, supported by specific audio codec.

If the encoder supports arbitrary sample rates within the supported rates range, *continuous is set to true, otherwise *continuous is set to false.

This function was introduced in Qt Mobility 1.0.
