Comment 4 for bug 945987

I talked with Jonathan today about this.
Currently the only way to get rhythmbox to use a new lame preset, is to first create the preset.
In python this looks like something like:

import gst;

l = gst.element_factory_make("lamemp3enc");
l.props.quality = 2.0;
l.save_preset("precise-defaults")

This will create the preset in ~/.gstreamer-1.0/presets/GstLameMP3Enc.prs

We will need to ship the preset so it ends up /usr/share/gstreamer-0.10/presets/ and reference it's name in the rhythmbox.gep.

Attached you will find the preset and the updated rhythmbox.gep which references this preset.
