How to extract the sound track from a flv file

Question

Is there anyway to extract the sound track from a flv file on MacOS X? If yes, what are the tool/ways I can do that?

Thank you.

Answer 1

Simply use MPlayer:

$ mplayer -dumpaudio input.flv

This command dumps the whole audio track in the original format into a file called "stream.dump". Thus, the file's audio track is dumped lossless.

Alternatively, try FFmpeg:

$ ffmpeg -i input.flv -f mp3 -vn -acodec copy output.mp3

Answer 2

You can use the freeware named FLV to Audio Converter for Mac.

Answer 3

I use AudioExtractor for this (web)

Answer 4

Avidemux: all platforms, all manner of video processing tasks including saving audio (optionally without a re-encode quality loss, where possible).
