Is libilbc DFSG compatible?

Hi,

Short version is: no problem with the one you linked to.

There are two common implementations of iLBC. One of them is "almost
free" from an older RFC:

This is a different (and incompatible) implementation of iLBC. It is
free and can be safely used in Debian. iLBC was the initial audio codec
in WebRTC implementations by Google and was released by them.

Thus the following two are OK. But can't be used as-is (without some
basic adaptation) for older code that was built for the former.

Go ahead!

Be sure to check which specific library they use. Though I gather that
nowadays most use the WebRTC one.
