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:

QObject::connect(BackendCapabilities::notifier(), SIGNAL(capabilitiesChanged()), ...

Notifier::capabilitiesChanged()

Notifier::availableAudioOutputDevicesChanged()

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();

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.

A list of AudioEffectDescription objects that give a name and description for every supported audio effect.
