Thank you,

I got success with the following line:

gst-launch vamp4sink name=sink location=./out.3gp { filesrc 
location=~/Dowload/AudioSample/m1_amrwb_23k05.wav ! wavparse ! audioscale 
frequency=8000 ! vaamrenc ! queue } ! sink.audiosink  { videotestsrc 
fourcc=I420 width=176 height=144 ! vah263enc  ! queue } ! sink.videosink

Now, I would like to know if it is possible to do the same thing with 
version 0.6.2 of GStreamer.  The parser seem to have change (0.6.2 vs VSS 
0.7), and I would like to make it work under 0.6.2.

I cannot find how to reuse the "name" of an element in the command line in 

Thank you for your help
