基于Qt的多媒体播放器
应用背景自己写的基于Qt的多媒体播放器,包含音乐播放器的必备功能,以及歌词显示,系统托盘,拖曳播放等扩展功能关键技术// 创建用来解析媒体的信息的元信息解析器
metaInformationResolver = new Phonon::MediaObject(this);
// 需要与AudioOutput连接后才能使用metaInformationResolver来获取歌曲的总时间
Phonon::AudioOutput *metaInformationAudioOutput =
new Phonon::AudioOutput(Phonon::MusicCategory, this);
Phonon::createPath(metaInformationResolver, metaInformationAudioOutput);
connect(metaInformationResolver, SIGNAL(stateChanged(Phonon::State, Phonon::State)),
this, SLOT(metaStateChanged(Phonon::State, Phonon::State)));
connect(mediaObject, SIGNAL(currentSourceChanged(Phonon::MediaSource)),
this, SLOT(sourceChanged(Phonon::MediaSource)));
connect(mediaObject, SIGNAL(aboutToFinish()), this, SLOT(aboutToFinish()));
