I just made a "silly" script to Convert flv files to mp3 using ffmpeg

Hello,

I proudly present my first all-made-by-me script which is converting flv files to mp3 using ffmpeg. You're also going to need libavcodec-unstripped-52 in order to succeed the conversion. Both ffmpeg and libavcodec-unstripped-52 can be apt-get install-ed. You can paste it to a new file inside ~/bin, make it executable with

chmode +x ~/bin/flv2mp3

and run it from terminal like that:

flv2mp3 inputfile.flv outputfile.mp3

or if you want to set the bit rate of the output mp3 to lets say 128kbps:

flv2mp3 inputfile.flv outputfile.mp3 128

It can also team up nicely with youtube-dl

And...here it is:

#!/bin/bash
#####################
## flv2mp3
#####################


if [ -z "$1" ]
then
  echo "No input file"
  echo "Help: $0 -h"
  exit
else
    case $1 in
        *.flv)
        input=$1 ;;
        -h) echo "Usage: $0 {inputfile.flv} {outputfile.mp3} {optional-bit-rate}"
            echo "ex: $0 test.flv test.mp3 192"
            exit;;
        *) echo "Input file is not flv" 
           echo "Help: $0 -h"
           exit;;
    esac
    
fi
if [ -z "$2" ]
  then
    echo "No output file"
    echo "Help: $0 -h"
    exit
else
    case $2 in
        *.mp3)
        output=$2 ;;
        *) output=$2".mp3"
    esac
fi
if [ -z "$3" ]
  then
    btr=""
else
    case $3 in
        *[!0-9]*|"") echo "Not acceptable Bit Rate"
                     echo "Help: $0 -h"
                     exit;;
        *)btr="-ab $3""k";;
    esac


fi
ffmpeg -i $input $btr $output
#end

I know it's not much, hence the "silly", but it was the best way to always "remember" how I can convert flvs to mp3s.
I hope it'll get handy to someone else too.

By the way this is my new ringtone

I just use

mplayer -vc null -vo null -dumpaudio -dumpfile audio.mp3 video.flv

Well, that's certainly annoying enough to make me want to answer the phone, if only to cut it off.
