m4p file conversion app

Postby Tempest on Tue Apr 07, 2009 10:33 pm

First off...I own the music - purchased it off of Itunes. My question is, does anyone know of an app that will convert these files from m4p to mp3? Prior to making this post, I searched these forums and found one entry about using VLC to convert the file, but that did not work for me. I could always boot the windows machine to listen to my music or have the ability to burn the music to cd, but I was hoping to avoid this... :-) If I could solve this problem and figure out some way to actually like open-office (hate to admit it, but MS Office 2007 is actually a great program), perhaps I would never need to turn on the windows machine. :D

Hi

I do not have any m4p files so cannot try, but make sure ffmepeg and lame
are installed and try;


Code: Select all
ffmpeg -i oldfile.m4p newfile.mp3


IF this works I am sure someone can come up with a script for bulk
conversion
I do not know if it will work with DRM files

Hi Nick,

Thanks for the reply. I am fairly new to Linux and Mint...so, can you tell me where I could install ffmepeg and lame from and I will give it a try... I did not see it in the Mint software manager...

HI

To install ffmepeg and lame, goto Synaptic and install from
there

Code: Select all
sudo synpatic


But m4p means they have DRM on them as opposed to m4a so I am not sure
it will work

There are programs for windows to convert which "may" run under
wine

The other way is to burn to a CD-RW and then rip as Mp3
not good if you have thousands :) :)

Hi Nick,

I did a search for those under synaptic and neither was listed. I checked the the repositories and had all checked. I will see if I can find them somewhere else. Being new to this, I was just hoping someone had already created an app that could do something like this. As popular as ITunes is, I am surprised if one does not exist especially if some have already been developed under Windows. I looked into some apps that do this in Windows, but u have to pay for them and I am somewhat leary of them. Thanks again for taking your time to help. :-) Hal

Hi

ffmpeg and lame should be in your repositories, unless you are using
the lite version (note I spelt ffmpeg wrong in last post.)

You could try http://hymn-project.org/

A deb package is available at; http://ftp.metu.edu.tr/pub/linux/debian ... in/h/hymn/

I tried something like this a while back after I copied some files off a colleagues iPod, I thought maybe I could convert them but I couldn't do anything with the m4p those files because they are DRM'ed and encrypted, I think the encryption is tied to the iPod and iTunes that created the files. It seems the only way round it is to use the original iTunes to burn the tracks to CD then you can rip them (can you get virtual CD-RW to save time??)

I also got some m4a files which weren't DRM'ed and could convert these easily, using faad or mplayer to get wav files then use lame to convert them to mp3.
If anyone is interested, I was looking at writing some scripts but I found something on wikipedia using find to do mass conversion really easily, run the following commands from the folder contaning all the sub-folders and files you want to convert (if you have loads then you need lots of space to create lots of wav files)
find -name '*.m4a' -exec faad '{}' ';'
find -name '*.wav' -exec lame '{}' ';'
find -name '*.wav' -delete
worked for me :) I then used gprename to rename any .wav.mp3 to .mp3

Hope this helps
