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
$ gst-inspect filesrc

我在這臺機器上使用Fedora 12從LiveCD到磁盤。我該如何解決它。 – YumYumYum 2011-04-13 19:00:40
這是缺少的：gstreamer-plugins-ugly.i686，但即使在installint之後，它仍然無法找到「filesrc」 – YumYumYum 2011-04-13 19:12:46
我解決了它，這個問題似乎很混亂。沒有人對此有過正確的答案。它只是在使用「yum -y install gstreamer etc」等軟件包時出現的錯誤或失敗，請參閱答案。希望它有助於其他人和包括我.. – YumYumYum 2011-04-13 22:52:22
