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.
# 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
if [ -z $1 ] ; then
if [ -d $CONVERTER_PATH ] ; then
for i in *.mp4
ffmpeg -i "$i" -f mp3 -ab 192000 -vn $(echo $i | sed 's/.\mp4/.\mp3/')
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/')
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"
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
