记录：继续探索moblin 2上的GSTREAMER：播放MP3及AVI文件

在Moblin 2 上使用Gstreamer播放MP3和AVI文件

1、机器环境，某个牌子NetBook

uname -a

Linux localhost
2.6.29.1-18.1.moblin2-netbook #1 SMP PREEMPT Fri Apr 17 17:25:17 UTC 2009 i686
i686 i386 GNU/Linux

2.播放MP3

2.1运行gst -launch filesrc location="bb.mp3" ! mad ! alsasink 报错

2.2.下载、编译、安装
gst-plugins-ugly-0.10.11及libmad-0.15.1b，需要解决一些编译问题。前者包含了系列的ugly的plugins，包括GStreamer的mad，mad依赖于libmad-0.15.1b。

2.3、运行成功。能够正确听到MP3中的音乐。
