Gstreamer“；filesrc"；在Fedora/Centos/Ubuntu中缺少与VLC交互的插件？在它可用之前

这是安装在我的盒子Fedora 12。和Rpmfusion存储库。但它仍然不允许我使用filesrc插件。我怎么能得到这个？注意：在我的另一个旧FedoraBox中，GST与filesrc一起运行，来自那些默认存储库。我试图使用filesrc加载一个简单的文件，并在普通Linux发行版中用VLC对其进行测试，但它不起作用。下面的测试已经在新的Fedora12中进行了（其他发行版也一样）

不确定如何不使用filesrc元素，它是corelements.so文件的一部分，因此，如果它丢失了，那么许多其他核心功能也应该丢失。以下是FC14上我的gst inspect命令的输出：

我在这台机器上使用Fedora12从LiveCD到磁盘。我该如何解决它呢？这是缺失的：gstreamer-plugins-ught.i686，但即使在installint之后，它仍然无法找到“filesrc”，我解决了它，这似乎让这个问题变得非常混乱。没有人对此有正确的答案。这只是使用“yum-y安装gstreamer等”安装包时出现的错误或失败，请参见答案。希望它能帮助别人，包括我。。

Problem (for me it happened for filesrc/audioconvert):
$ gst-inspect filesrc
No such element or plugin 'filesrc'

Step 1:
$ gst-inspect -b

Blacklisted files:
  libgstpython.so
  libgstcoreelements.so

Total count: 2 blacklisted files


Step 2:
$ rm ~/.gstreamer-0.10/registry*
rm: remove regular file `/root/.gstreamer-0.10/registry.i386.bin'? y
$ gst-inspect /usr/lib/gstreamer-0.10/libgstcore
$ gst-inspect /usr/lib/gstreamer-0.10/libgstcorelibgstcoreelements.so
No such element or plugin '/usr/lib/gstreamer-0.10/libgstcorelibgstcoreelements.so'

Step 3: suddently it works, just doing Step 1 and Step 2
