------- Comment #1 from Tim-Philipp Müller 2007-05-15 11:29 UTC -------
This is not a bug in this case. Your pipeline is faulty. Try something like:

gst-launch-0.10 filesrc location=foo.mp3 ! mp3parse ! udpsink host=...

or

gst-launch-0.10 filesrc location=foo.mp3 ! decodebin ! audioconvert !
audioresample ! lame ! udpsink host=...


If that doesn't work, please seek advice on the gstreamer-devel mailing list or
stop by on IRC.
