I’m sure you could also do the scripting part with a batch file, but this was easier for me:

1. Get MPlayer for Win32 from over here

2. Do some ruby magic:

1
2
3
4
5
6
7
8
9
10
11
12
13


require "Fileutils"

input_files = Dir["*.flv"]

input_files.each{|filename|
prefix = filename.split(".")[0]

commandline="MPlayer-p4-svn-27811\\mplayer.exe -dumpfile \"#{prefix}.mp3\" -dumpaudio \"#{prefix}.flv\""
puts "Executing: " + commandline
IO.popen (commandline) { |f| puts f.gets }
}

3. Profit!
