我能够将.mp3文件转换为.wav文件.

但是,当我尝试将相同的.wav文件转换回.mp3时,我收到以下错误：输出流#0.0不支持的编解码器

me@me-desktop:~$ffmpeg -i Desktop/output.wav Desktop/output2.mp3
FFmpeg version SVN-r0.5.1-4:0.5.1-1ubuntu1.1,gcc: 4.4.3

Stream mapping:

我已经尝试按照上一个问题的建议安装unstripped-51但我仍然无法将.wav转换为.mp3

解决方法

我建议使用跛脚：

lame -b 192 -h input.wav output.mp3  # bitrate 192,highest quality

如果你没有它,apt-get install lame.

有关更多选项和/或示例,请参阅man lame.
