fedora下安装MP3，视频解码器提示 No package,,,,,,,,,,,available解决办法

1、su root

2、yum install gstreamer-plugins-ugly gstreamer-plugins-bad gstreamer-ffmpeg

如果出现“No package gstreamer-plugins-ugly available.No package gstreamer-plugins-bad available.No package gstreamer-ffmpeg available.”等错误，则需要安装YUM源，其方法如下：

rpm -ivh http://rpm.livna.org/livna-release.rpm
rpm -ivh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm
rpm -ivh http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm
安装完成后再重复第一步即可。

然后打开一首歌，，，，惊喜！！！
