我
安装的是qt-win-opensource-4.8.4-vs2008.exe，配合vs2008使用，编写代码如下：
- #include "userdefinecontrol.h"
- #include <QtGui/QApplication>
- #include <phonon/MediaObject>
- #include <phonon/VideoPlayer>
- #include <phonon/BackendCapabilities>
- int main(int argc, char *argv[])
- {
- QApplication a(argc, argv);
- // Phonon::MediaObject *music =
- // Phonon::createPlayer(Phonon::MusicCategory, Phonon::MediaSource("D://test.mp3"));
- Phonon::MediaObject *music =
- Phonon::createPlayer(Phonon::VideoCategory, Phonon::MediaSource("D://test.avi"));
- music->play();
- return a.exec();
- }
，但是
执行的时候却没有任何音视频播放。
学习Advanced Qt Programming的时候，下载了aqt的配套源码playmusic，用vs2008中的Qt菜单进行导入（“Open Qt Project File (.pro)”）时，输出
错误如下：

请问大侠，这是不是说明安装的4.8.4还是没有包含phonon模块啊？
