这个帖子没有图，好吧，找一张小的帖上，要不对不起大家了

够小吧，手里是根大葱，对，就是根葱，好啦，香蕉到手已经有一段时间啦，听说M2要出来啦，学生套又涨价啦，闲话少说，香蕉有3.5的音频输出口怎么让她输出音乐呢，查资料，很简单

参考了这篇文章，就不做链接了，防止被吃掉：

1、测试

root@bananapi:~# mplayer test.mp3
-bash: mplayer: command not found

2、安装

root@bananapi:~# apt-get install mplayer

3、播放

root@bananapi:~# mplayer test.wav

据说这个播放器很强大，可以播放网络上的音乐

root@bananapi:~# mplayer "http://yinyueshiting.baidu.com/data2/music/124574160/49046814400128.mp3?xcode=631ddae65590b6ba250388445b5acdc7b88a242702f69397&song_id=490468"

注意要加引号，原文中没有说，否则会报错的，这个是《独脚戏》估计是百度临时的url所以过一段时间试不一定有效，找新的吧

既然强大，应该也能播放avi，不过还是报错了

一堆洋文，看不懂，似乎是支持的，可能是没有地方显示，好吧，看看help，应该是可以加个参数关掉视频的
