Function Documentation

PHONON_EXPORT Notifier* Phonon::BackendCapabilities::notifier ( )

Use this function to get a QObject pointer to connect to one of the Notifier signals.

Returns
a pointer to a QObject.

To connect to the signal do the following:

Notifier::availableAudioCaptureDevicesChanged()
PHONON_EXPORT QStringList Phonon::BackendCapabilities::availableMimeTypes ( )

Returns a list of mime types that the Backend can decode.

See also
isMimeTypeAvailable()
PHONON_EXPORT bool Phonon::BackendCapabilities::isMimeTypeAvailable ( const QString mimeType)

Often all you want to know is whether one given MIME type can be decoded by the backend.

Use this method in favor of availableMimeTypes() as it can give you a negative answer without having a backend loaded.

availableMimeTypes();
PHONON_EXPORT QList<AudioOutputDevice> Phonon::BackendCapabilities::availableAudioOutputDevices ( )

Returns the audio output devices the backend supports.

Returns
A list of AudioOutputDevice objects that give a name and description for every supported audio output device.
PHONON_EXPORT QList<AudioCaptureDevice> Phonon::BackendCapabilities::availableAudioCaptureDevices ( )

Returns the audio capture devices the backend supports.

Returns
A list of AudioCaptureDevice objects that give a name and description for every supported audio capture device.
PHONON_EXPORT QList<EffectDescription> Phonon::BackendCapabilities::availableAudioEffects ( )

Returns the video output devices the backend supports.

Returns
A list of VideoOutputDevice objects that give a name and description for every supported video output device. Returns the video capture devices the backend supports.
A list of VideoCaptureDevice objects that give a name and description for every supported video capture device. Returns the visualization effects the backend supports.
A list of VisualizationEffect objects that give a name and description for every supported visualization effect. Returns descriptions for the audio effects the backend supports.
