The following is based on the documentation available here.
By getting involved with Phonon, you can choose between three different main tasks.
The following example is taken from englishbreakfastnetwork. It lets you select a music file and plays it. 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:
project (tutorial2) find_package(KDE4 REQUIRED) include (KDE4Defaults) include_directories(${KDE4_INCLUDES}) set(tutorial1_SRCS main.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); Phonon::createPath(media, new Phonon::AudioOutput(Phonon::MusicCategory, this)); media->setCurrentSource(QFileDialog::getOpenFileName(0,QString("Select a file to play"),QString())); 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 "main.moc"
cmake . && make && ./tutorial2
