To begin with:
  1) gstreamer-0.10 has no { } syntax for gst-launch any more. Just
remove them.
  2) You probably want a queue on the video part too
  3) Don't use ffdec_mp3 for any purpose ever, I don't think it works
much.
  4) After your mp3 decoder, add an audioconvert and perhaps an
audioresample. 
  5) If it still doesn't work, then there's something else wrong too :-)
