I appologize in advance if this info is already somewhere on the forum...it escaped my searching
Anyone who has ripped CDs to play on an iPod or personal machine in iTunes was likely using the AAC format and possibly bummed to not be able to listen to those files in Linux. This should remedy your troubles.
This HOWTO will allow you to play mp3 and m4a files in Rhythmbox on FC4. I assume you've installed a fairly standard desktop setup, with Rhythmbox, on an i686 machine.
To begin, in a root terminal, you should add the livna source (for additional programs/libraries) to yum by running
rpm -ivh http://rpm.livna.org/fedora/4/i386/RPMS.lvn/livna-release-4-0.lvn.2.4.noarch.rpm
Next, if you've installed the gstreamer-plugins-mp3, remove it since it will conflict with the rpm version installed below. That can be removed by typing
yum remove gstreamer-plugins-mp3
Next, you'll need to fetch some additional libraries and the gstreamer-plugins for mp3 and m4a files by typing
Next you'll install the libraries and plugins by typing
rpm --import http://freshrpms.net/packages/RPM-GPG-KEY.txt
yum install faad2 gsm
rpm -ivh liba52-0.7.4-1.i686.rpm libmpcdec-1.2-1.2.fc4.i386.rpm gstreamer-plugins-extra-audio-0.8.8-2.2.fc4.i386.rpm
You'll then need to register the new gstreamer plugins by typing
At this point everything is installed and should be ready to go. You may need to reboot, but I suggest launching Rhythmbox and trying to add some mp3 and m4a files.
Please post any errors or problems you encounter and I'll happily update the post.
Edit 1: Fixed install of gstreamer-plugins-extras-audio to grab dependencies autmatically (using yum rather than rpm)
Edit 2: Streamlined installation
Edit 3: Fixed wget cut and paste boo boo
Edit 4: Added copying of GPG key
Edit 5: Reverted to old method of install until I have time to clean things up...at least it should work properly (error free) now. I'll fix it eventually...
