Multiple pipelines in one gst-launch

[E-J van der Linden]

I try to have two pipelines in one gst-launch command.

gst-launch -v alsasrc ! "audio/x-raw-int,channels=2,rate=44100,depth=32,height=32" ! audioconvert ! rtpL16pay ! udpsink host=localhost port=8000 \
udpsrc port=8000 ! "application/x-rtp,media=audio,clock-rate=44100,channels=2,payload=96" ! rtpL16depay ! alsasink sync=false

The output is

Setting pipeline to PAUSED ...

I see that the second pipe doesn't run, there isn't sound !!
When I run two gst-launch commands, there is sound.

The thing is that I want to program the two pipelines in one program and if I can't get this to work with gst-launch I think I can't program it...
