fedora 17 下配置mp3和RMVB播放

关于mp3 mp4格式解决：
1.添加软件源#

sudo rpm -ivh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm

2.更新yum 缓存#

sudo yum makecache

3. 安装播放器和解码器#

sudo yum install ffmpeg ffmpeg-libs gstreamer-ffmpeg xvidcore libdvdread libdvdnav lsdvd gstreamer-plugins-good gstreamer-plugins-bad gstreamer-plugins-ugly gstreamer-plugins-bad gstreamer-ffmpeg gnome-mplayer

关于播放器乱码，设置登陆全局环境变量即可：
export GST_ID3_TAG_ENCODING=GB18030:UTF-8
export GST_ID3V2_TAG_ENCODING=GB18030:UTF-8
在/etc/profile里面加这俩句然后重新在Rythmbox里重新导入歌曲，重新登陆后即可.
