mencoder rmvb压缩mp3

最近很喜欢看crash里面的英语也很不错,也可以当练英文的“工具”。所以在Linux下面使用mencoder把rmvb压缩成mp3

打开一个terminal然后运行。比如说1是rmvb文件。那么运行下面命令输入2.mp3

mencoder 1.rmvb -oac mp3lame -lameopts preset=32 -lameopts ratio=100
-lameopts aq=9 -lameopts br=3 2 -ovc frameno -of rawaudio -o 2.mp3

or

mencoder input_file.rm -ovc frameno -oac mp3lame -of rawaudio -lameopts cbr:br=128 -o output_file.mp3

-o <filename> the filename to save the encoded file to
-ovc <video codec> OVC stands for ‘output video codec’. This is the library you want to use to encode the video
-oac <audio codec>
OAC stands for ‘output audio codec’. This is the library you want to encode the audio portion with.

You can pass more options using -lameopts foo=bar
* abr sets average bitrate.
* cbr uses a constant bitrate.
* br=<0-1024> sets bitrate in kbps, for CBR and ABR only
