FMS FLV to mp3/aac/wav

Question

How can I decode a FLV's audio if it's recorded from a live stream using Flash Media Server and uses NellyMoser codec?

I'm writing a script that process several FLVs, using FFmpeg, so I need a command line solution.

Any ideas?

Answer 1

This should work for you, since NellyMoser is supported by FFmpeg.
1. Using mp3

ffmpeg -i yourinput.flv -vn -acodec libmp3lame output.flv

2. Using AAC (switch aac with libfaac depending on which you have loaded)

ffmpeg -i yourinput.flv -vn -acodec libfaac output.mp4

I'm assuming of course you dont care about video.
