 hi,
I tried your suggestion and got the output below, but still I can not get w=
here the problem is, actually I don't know what kind of output is normal(so=
me info in the end of line is not showing correct, since i just copy them f=

here are the info:
***************************************************************************=

it seems i do get some thing output from the decoder and they are put into =
the sink.

Hi, maybe you can first try replacing the osssink by a fakesink and setting=
 it's property dump=3Dtrue : gst-launch-0.10 -v filesrc location=3D~/Media/=
test.mp3 ! mad ! audioconvert ! audioresample ! fakesink dump=3Dtrue then t=
ry the GST_DEBUG : GST_DEBUG=3D"baseaudiosink:4, audiosink:4" gst-launch-0.=
10 filesrc location=3D~/Media/test.mp3 ! mad ! audioconvert ! audioresample=
 ! osssink Cheers, -- Ali On Thu, 2007-09-20 at 09:50 +0800, Joyious He wro=
