You want to lower the the CPU usage in the mp3 deoder not in
gstreamer as you found out it is caused by the mp3 decoder. You'll
need to get a mp3 decoder that performs better. Some time ago people
wrote a decoder based on libmpg123, but it is incomplete and noone
ever bothered to make it mature and submit it for inclusion with
gstreamer.<br>
