can you use GStreamer here since that includes the SBC encoder and
decoder as elements. You can construct the pipeline as you like.

Meaning that Ekiga would be a GStreamer source. Of course you would have
to write that specific source element.

Having Ekiga as a GStreamer sink sounds like a good idea.

What kind of legal reasons are you talking about here. The SBC
implementation is released under LGPL. Worst case issue here is that you
actually build an independent library out of it and just link it
dynamically. We were planning to do so anyway, but currently that is not
really sufficient for us. It would just create a maintenance overhead.
