GStreamer运行时错误

GStreamer Runtime Error

它尝试运行GStreamer教程示例，该示例已经起作用，但现在不再起作用。我没有更改源代码。我用CMake构建项目。

我的每个测试程序都会出现以下错误，它们彼此略有不同：

(GStreamer_Test_AppSrc:28073): GLib-GObject-CRITICAL **: g_param_spec_boxed: assertion `G_TYPE_IS_BOXED (boxed_type)' failed

问题是，我安装了GStreamer 0.10.x AND 1.x，并将两者分别混合在一起CMake。

当我试图用GStreamer 1.x编译我的项目时，CMake记得一些缓存设置。在清理了CMake项目的源代码外构建目录并仅用GStreamer-0.10.x依赖项重新构建项目后，我的程序再次按预期工作。
