mp3 plugin for rhythmbox

[umberto rossi]

Since my Rhythmbox does not read MP3s I have downloaded a plugin from
Fluendo, because several websites said that was an easy solution, but
now that I have the file (libgstflump3dec.so) I do not know where I
should put it... the instructions in the install file that cames with
the plugin do not seem to have had any real effect (they should create a
folder and copy the file there, but it seems the folder has not been
created, or I haven't been able to find it). Anyway, the Rythmbox can't
read mp3s...

Btw, these are the instructions I found in the install file:

To install this GStreamer plug-in:

- make sure you have a plugins directory in your home directory:
  mkdir -p $HOME/.gstreamer-0.10/plugins

- copy this plug-in there:
  cp libgstflump3dec.so $HOME/.gstreamer-0.10/plugins

- verify that it works:
  gst-inspect-0.10 flump3dec

Can anybody help?
