Naturpic Video to MP3 is a powerful tool that not only can convert video to audio (for example, AVI to MP3), but also can convert video to video (for example, MKV to WMV). This software supports various formats like 3GP, AAC, APE, AVI, M4A, MP3, MP4, OGG, F4V, FLV, MOV, MKV, VOB, WMA, WMV, etc. It's very useful for those people who collect some music VIDEOs and only want to play the audio stream for some reasons. It doesn't install any codecs on your computer because all encoders/decoders are built-in.
