[Nice] Starting with libnice

[Tiago Sá]

Hi Youness,

I have been trying to create a simple application based on the first link
you pointed before.
Thanks for the tips you gave me. I have a couple of questions though, if
you can help me.

I need to find a way to get the remote candidates passed from a peer to
another.
Can you point an easy way to do that?
Could I hardcode the remote candidates list, for testing purposes?

Right now, I only get two local candidates (HOST and SERVER_REFLEXIVE).
I am trying to use the numb TURN server, shouldn't I get a RELAYED
candidate too?

I am attaching the code. Can you please have a look at the code and check
where the error could be?

Thanks for helping!

Regards,
Tiago Sá
