我在WinXP上遇到声音直接显示后端的问题。基本上它对我来说根本不起作用我已经尝试了 4.7.0 SDK 和从源代码构建的版本。在这两种情况下, phonon_ds94.dll 都位于/ plugins / phonon_backend / dir中。我的系统是WinXP,我使用VS 2008。
这是我创建视频播放器的方式:
vp = new Phonon::VideoPlayer(this);
...
vp->play(QUrl("..."));
在正常的程序运行中,这是我的输出:
WARNING: Phonon::createPath: Cannot connect Phonon::MediaObject ( no objectName ) to Phonon::VideoWidget ( no objectName ).
这是我在调试运行qt-creator时得到的输出:

有没有人有任何想法?
答案 0 :(得分:0)
我记得有一点感到沮丧。您的'phonon_ds94.dll'是否使用相同版本的Qt构建?它必须与版本号匹配,并且是正确的“Debug”或“Release”构建类型。链接“Debug”Qt库的应用程序不会加载“Release”插件,反之亦然。
另外,如果您正在构建针对调试qt库的构建,您可以进入插件加载代码,看看为什么它没有拿起您的声子后端。
