mplayer 不能播放某些rmvb文件的音频(AAC音频？)

linuxjerry

我的mplayer是MPlayer 1.0pre5-3.4.1 (C) 2000-2004 MPlayer Team
基本上正常，就是遇到一些rmvb的文件放不出声音，它是用哪中音频编码呢？real的codecs我都装了，包括rp32win，各位大虾，帮我看看这么解决啊。
我在google上找了很久都找不到缺什么，看到有类似的说不要用internal faad，要用external faad，我就去找faad来，又不会编译。

我的./mplayer/codecs.conf里面关于faad的内容如下：
audiocodec faad
  info "FAAD AAC (MPEG2/MPEG4 Audio) decoder"
  status working
  fourcc mp4a,MP4A
  fourcc "AAC " ; Used in NSV
  format 0xff
  driver faad
  dll libfaad2
我去下载了一个faad2-2.0.tar.gz，又不会编译。
]$ cd faad2

To compile under Linux.
----------------------
just run :
- autoreconf -vif
then run configure with options you want.
run ./configure --help for more informations.

about the xmms plugin.
---------------------
The xmms plugin need to be build after the install of the faad project.
so after you have installed correctly faad (--with-xmms options) you need
to configure and build the xmms plugin part in the plugins/xmms directory.
Read the README and INSTALL files into the xmms directory.
可是我找不到autoreconf来run。

这一部分信息是不是说文件坏了？

编译时没有加相应参数，默认不支持faad音频。
解决方法就是重新编译加上 --enable-external-faad 配置参数。

谢谢楼上两位，我是rpm安装的，也加--enable-external-faad参数吗？晚上试试。
