Copy the sound content of a video to an mp3 file

ffmpeg -i source.flv -vn acodec copy destination.mp3
-vn removes tha video content, the copy option tells ffmpeg to use the same codec for generating the output

What Others Think

That, of course, will only work properly if you have a video source with an mp3 audio stream. If you downloaded an mp4, or an mov, it's likely to have an aac audio stream. I, personally, would keep it as aac, since I think it's a better codec. To do that, one could do: ffmpeg -i source.mp4 -vn -acodec copy destination.aac But if you really want an mp3, just take out -acodec copy, since ffmpeg is smart enough to figure it out. ffmpeg -i source.mp4 -vn destination.mp3 If you do want to be explicit, try: ffmpeg -i source.mp4 -vn -acodec libmp3lame destination.mp3 Of course, that won't work on many Linux distributions because they disable mp3 encoding in ffmpeg, unless you compile it from source.
