Is libilbc DFSG compatible?

[Pali Rohár]

Hello!

In past there were problems with iLBC implementation found in RFC3951
and some software had removed its implementation from source packages.

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=393402
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=664606
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=665938

In following git repository is extracted WebRTC implementation of iLBC
which claims "drop-in replacement for the non-free code from RFC 3591".

https://github.com/TimothyGu/libilbc

And there is also RFP bug:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=675959

So obvious question: Is this libilbc implementation DFSG compatible and
could be included into Debian archive?

If yes then I'm interested in packaging this library in Debian.

There are more applications which supports iLBC (e.g. ffmpeg) but in
Debian it is disabled at compile time due to missing library.
