You can get help on #phonon on irc.freenode.org.
See Development/Tutorials/Phonon/Introduction/Python for the same example in Python.
The following is based on the documentation available here Phonon API.
By getting involved with Phonon, you can choose between three different main tasks.
Beginners will probably be more interested by the first task.
The following example is taken from http://www.englishbreakfastnetwork.org/apidocs/apidox-kde-4.0/kdelibs-apidocs/phonon/html/index.html. It plays /tmp/example.wav. To change the sound device that is used by default, use the command systemsettings.
You need a file CMakeLists.txt to compile the software later:
CMakeLists.txt project (tutorial2) find_package(KDE4 REQUIRED) include (KDE4Defaults) include_directories(${KDE4_INCLUDES}) set(tutorial1_SRCS tutorial2.cpp) kde4_add_executable(tutorial2 ${tutorial1_SRCS}) target_link_libraries(tutorial2 ${KDE4_KDEUI_LIBS} phonon) install(TARGETS tutorial2 ${INSTALL_TARGETS_DEFAULT_ARGS})
#include <phonon/mediaobject.h> #include <phonon/audiooutput.h> #include <QtGui/QApplication> #include <QtGui/QMainWindow> #include <QUrl> class MainWindow : public QMainWindow { Q_OBJECT public: MainWindow(); }; MainWindow::MainWindow() { Phonon::MediaObject* media = new Phonon::MediaObject(this); createPath(media, new Phonon::AudioOutput(Phonon::MusicCategory, this)); media->setCurrentSource(QUrl("/tmp/example.wav")); media->play(); } int main(int argc, char **argv) { QApplication app(argc, argv); QApplication::setApplicationName("Phonon Tutorial 2"); MainWindow mw; mw.show(); return app.exec(); } #include "tutorial2.moc"
cmake . && make && ./tutorial2
