In a fork of seanbright's opus patch for 13 there are further patches
for Forward Error Correction and Package Loss Concealment, both of which
ought to very useful in voip:

https://github.com/traud/asterisk-opus

Anybody used these patches ? Puzzled why they weren't committed to the
main patch.

We're testing this branch for a while, not with the latest commits.

For now, it works, however, time to time audio quality issues with transcoding, but I don't know yet where is the problem.


We'll test with the latest commits.


BTW, it isn't included in the main because potential patent license issues.

Those two patches are not on the opus code and hence this is irrelevant
to them (regardless of what I personally think about the patent
concerns).

While not on the opus code itself, the patches claim to allow FEC ,
which otherwise has problems, at least with HD voice :

https://github.com/seanbright/asterisk-opus/issues/9

Or am I missing something ?
