Look at the pipeline_description for mp3 in gconf. When you have it, try running the command:
$ gst-launch-0.10 fakesrc ! $DESCRIPTION ! fakesink Does the above command fail with an error, or simply sit until you Ctrl+C? For me, it starts up fine and runs until I type ctrl+c. For the record, my pipeline_description is as follows: audio/x-raw-int,rate=44100,channels=2 ! lame name=enc mode=0 vbr- quality=6 ! id3v2mux -- 0.9.8 iPod writing not working in Feisty https://launchpad.net/bugs/86920 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
