Change codec of WAV file

Question

Is there a way to change the codec/format of WAV file? Can I use ffmpegor anything else?

From

RIFF (little-endian) data, WAVE audio, Microsoft PCM, 8 bit, mono 8000 Hz

to

RIFF (little-endian) data, WAVE audio, ITU G.711 u-law, mono 8000 Hz

UPDATE

root]# ffmpeg -codecs
FFmpeg version SVN-rUNKNOWN, Copyright (c) 2000-2007 Fabrice Bellard, et al.
configuration: --enable-shared --disable-static --enable-amr_nb
libavutil version: 49.3.0
libavcodec version: 51.38.0
libavformat version: 51.10.0

ffmpeg: missing argument for option '-codecs'

UPDATE2: And here is what happen when I try

root]#ffmpeg -i 110.wav -c:a pcm_mulaw new.wav
FFmpeg version SVN-rUNKNOWN, Copyright (c) 2000-2007 Fabrice Bellard, et al.
configuration: --enable-shared --disable-static --enable-amr_nb

Input #0, wav, from '110.wav':
Duration: 00:00:06.8, start: 0.000000, bitrate: 64 kb/s
Stream #0.0: Audio: pcm_u8, 8000 Hz, mono, 64 kb/s
ffmpeg: unrecognized option '-c:a'

Solution

It's pretty simple:

ffmpeg -i input.wav -c:a pcm_mulaw output.wav

Check ffmpeg -codecs for a list of supported codecs. An E in the listing means encoding support.

Dude, why is your version of ffmpeg from 2007?

[S.I.]

Hm.. it's seems that there is no codecs on the system. Please check my updated question.

Well, you're running a version from 2007 (that's seven years old!), so head to ffmpeg.org/download.html and download a new static build.

Yeah .. the linux distribution on this machine is also from the prehistoric but I can't 'refreshing' it at this time. I'll try to update ffmpeg at least and will let you know if it's work the conversion

Ok, I've tried ot virtual box under Ubuntu. The output file is RIFF (little-endian) data, WAVE audio, ITU G.711 mu-law, mono 8000 Hz which is good OK but is there a differents between ITU G.711 mu-law and ITU G.711 u-law? What is this m in mu-law?

[S.I.]

Also I don't see codec just for u-law so is mu-law same as u-law?
