OT : mp4 to mp3 conversion tool

Hi All I have decided to share with you something I did for my self as I found my self doing many conversion of mp4 to mp3 for my iPhone, i did an automation script that takes the path of a directory or file and convert all mp4 to mp3.

#!/bin/bash

# mp4tomp3

#

# Cool Tool created to automate the conversion process of mp4 files to mp3

#

# Creator : Shiran Guez

#

# Created under ubuntu but should work on any linux distribution 

# That have ffmpeg installed

#

#

CONVERTER_PATH=$1

if [ -z $1 ] ; then

    CONVERTER_PATH=$(echo "`pwd`")

fi

if [ -d $CONVERTER_PATH ] ; then

    for i in *.mp4

    do

        ffmpeg -i "$i" -f mp3 -ab 192000 -vn $(echo $i | sed 's/.\mp4/.\mp3/') 

    done

    echo "Done"

else 

    file $CONVERTER_PATH | grep "MPEG v4"

    if [ $? -eq 0 ] ;then

        ffmpeg -i "$CONVERTER_PATH" -f mp3 -ab 192000 -vn $(echo $CONVERTER_PATH | sed 's/.\mp4/.\mp3/')

    else

        echo "That is not a valid format of mp4 file to convert"

        echo "either provide a path of  directory containing mp4 extensions"

        echo "or provide a path to a valid mp4 file"

    fi

fi

I moved the script to /usr/sbin and added excutable priv “chmod +x /usr/sbin/mp4tomp3” to run it simply run the command from cli example:

sudo mp4tomp3 <path_of_dir or file_name>

or just under the directory you have files to convert

cd /to/desired/path sudo mp4tomp3

enjoy
