Description Miguel Luis 2007-05-15 11:05:20 UTC 
Please describe the problem:
When trying to run a pipeline with gst-launch-0.10 that uses lame encoder it tells to report a bug.

Steps to reproduce:
1. gst-launch-0.10 filesrc location=Woman.mp3 ! lame ! udpsink host=127.0.0.1 port=9090 typefind


Actual results:
Program tells to report a bug.


Expected results:
Something less than a bug, maybe pipeline starts prerolling.

Does this happen every time?
Yes.

Comment 1 Tim-Philipp Müller 2007-05-15 11:29:45 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.
