FMS FLV to mp3/aac/wav

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?

Solution

  • 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.
