Phonon was originally created to allow KDE 4 to be independent of any single multimedia framework such as GStreamer or xine and to provide a stable API for KDE 4's lifetime. It was done for various reasons: to create a simple KDE/Qt style multimedia API, to better support native multimedia frameworks on Windows and Mac OS X, and to fix problems of frameworks becoming unmaintained or having API or ABI instability. Subsequently it has been moved to Qt and can therefore be used independent of KDE. For example, a file can be played in four lines of C++ code,〔 〕 compared to 30 lines in the old audio framework for KDE (aRts)〔 〕 Phonon::MediaObject * media = new Phonon::MediaObject(this); createPath(media, new Phonon::AudioOutput(Phonon::MusicCategory, this)); media->setCurrentSource(QUrl("/tmp/example.wav")); media->play(); Phonon is not designed to have every conceivable multimedia feature, but rather as a simple way to perform common functions of computer media players. Developers that require more control over a given media backend than Phonon can provide are recommended to use the native media API or the GStreamer API on systems for which it is available.〔 == History == The idea behind Phonon started at aKademy 2004 in Ludwigsburg near Stuttgart (Germany), where a new multimedia API had to be chosen to replace aRts. No consensus was reached but a few developers got together and decided to try to develop a new framework with multiple backends. The earliest version was called KDEMM (KDE MultiMedia) and was only supported by JuK and Amarok. Matthias Kretz continued to work single handed on the project as part of his university thesis, The project changed name once more but in February 2006 the name Phonon was finally chosen. The first official release was part of KDE 4.0 in January 2008, the same year Phonon was adopted by Qt and released as part of Qt 4.4. Even though support for Phonon in Qt will continue for the 4.x series, Qt has already replaced Phonon with QtMultimedia and QtMobility.〔(【引用サイトリンク】title=Qt Multimedia/Mobility vs. Phonon: FIGHT!!! )〕〔(【引用サイトリンク】title=QtMultimedia Module )〕〔(【引用サイトリンク】title=Qt Mobility Project APIs Overview )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Phonon (software)」の詳細全文を読む スポンサード リンク
