[Nice] Turn in libnice

[Youness Alaoui]

Hi,

This is basically the question about "how open is google". They released
libjingle by taking a snapshot of their development tree at some point, then
they completely modified how the turn server works, but never updated/released
that.. I personally never tried libnice against the turn server from libjingle,
but I've read its code (headache) and I had to reverse engineer the real google
servers because they work completely differently from what's in libjingle's code.

If you use the NICE_COMPATIBILITY_GOOGLE mode, then it's possible it won't work
with the libjingle turn server simply because it's outdated. I suggest you try
it and see for yourself whether or not it works.

Either way, I see absolutely no reason any sane person in the world would decide
to use libjingle for anything (apart from looking for a migraine). If you want a
TURN server, I suggest you check turnserver.org as Marcus suggested. They should
have a version that uses draft 9 of the TURN spec (which is what libnice
currently supports), but I will soon review patches from Marcus and merge proper
TURN RFC support into libnice which should make it work with the latest version
of turnserver.org.
Other solution would be to (temporarily) use Marcus' branch of libnice until it
get merged upstream : https://github.com/mlundblad/libnice/

Hope it helps.
Youness.
