Convert mp4 to mp3
Hello everybody,
Could you please suggest me a quick way to convert just the audio of movies from AC3 to MP3 ? I would like to get a new Avi with the same video, but different audio (mp3). OS: windows 7.
(I do not need to convert video, just audio)
thank you !

You can do it with ffmpeg. Try a command line like this:
ffmpeg -i <input_filename> -f <container> -vcodec copy -acodec libmp3lame -ar 44100 -ab 128k -ac 2 <output_filename>
Replace the <> stuff with whatever filenames and containers you are using. Do note that this will downmix surround to 2 channel audio.

Could downmixing be avoided by removing -ac 2? – user1686 – 2011-03-20T17:03:38.447
