[SR-Users] RtpEngine and iLBC support

[Lars Olsson]

Hi,

Can anyone give a quick answer regarding RtpEngine and support for iLBC
codec?

I have followed the instructions how to build and enable codecs according
to the GitHub manual. But iLBC codec is missing when performing "rtpengine
--codecs".

I have tried to google around for iLBC references, but the only thing that
I have found so far is libilbc, which is a lib for ffmpeg, and it looks
like ffmpeg needs to be recompiled.

What is the correct/fastest way forward for getting iLBC support on
RtpEngine on debian 9?
The purpose it to test a-law to iLBC transcoding.

Best Regards,
Lars

You need an ffmpeg (libavcodec) that supports it. For Debian Stretch,
this is achievable with the packages from
http://www.deb-multimedia.org/, e.g. libavcodec57 version
10:3.3.8-dmo1+deb9u1.
