[gst-devel] adder: Trying to get my head around it

[John R.]

Hello,

The following pipeline works for me:

gst-launch-v alsasrc ! audioconvert ! audioresample ! audio/x-raw-int, 
rate=8000, channel=1 ! alsasink device=bluetooth sync=false

Now I want to mix in the bluetooth mic input.  I have tried a variety of 
pipelines but have not gotten it to work.


This one seems the closet but fails at some point:

-0.10 -v alsasrc ! audioconvert ! audioresample ! audio/x-raw-int, 
rate=8000, channel=1 ! adder name=mix ! alsasink device=bluetooth 
sync=false alsasrc device=bluetooth ! mix.

Any ideas?
