AudioOutput Class Reference
(Phonon::AudioOutput)
[Phonon module]

Detailed Description

The AudioOutput class is used to send data to audio output devices.

The AudioOutput class plays sound over a sound device. The audio output needs to be connected to a MediaObject using createPath(). To start playback, you call play() on the media object.

     Phonon::MediaObject *mediaObject = new Phonon::MediaObject(this);
     mediaObject->setCurrentSource(Phonon::MediaSource("/mymusic/barbiegirl.wav"));
     Phonon::AudioOutput *audioOutput =
         new Phonon::AudioOutput(Phonon::MusicCategory, this);
     Phonon::Path path = Phonon::createPath(mediaObject, audioOutput);

The class supports changing the volume(). It is also possible to mute the sound.

To find out what AudioOutputDevices are available for AudioOutput, you can call BackendCapabilities::availableAudioOutputDevices(). A default device is selected by the backend, but it is possible to set the device to be used with setOutputDevice(). The outputDeviceChanged() signal will be emitted if the device changes.

If an error occurs with the playback, for instance, if no valid output device is found, the media object will receive a stateChanged() signal with the ErrorState.

Note that the default values of properties are dependent on the backend.
