<a name="libilbc"></a>
<h2 class="section"><a href="general.html#toc-libilbc">1.8 libilbc</a></h2>

<p>iLBC is a narrowband speech codec that has been made freely available
by Google as part of the WebRTC project. libilbc is a packaging friendly
copy of the iLBC codec. Libav can make use of the libilbc library for
iLBC encoding and decoding.
</p>
<p>Go to <a href="https://github.com/dekkers/libilbc">https://github.com/dekkers/libilbc</a> and follow the instructions for
installing the library. Then pass <code>--enable-libilbc</code> to configure to
enable it.
</p>
<a name="AviSynth"></a>
<h2 class="section"><a href="general.html#toc-AviSynth">1.9 AviSynth</a></h2>

<p>Libav can read AviSynth scripts as input. To enable support you need a
suitable &lsquo;<tt>avisynth_c.h</tt>&rsquo; header to compile against. The header in
classic AviSynth&rsquo;s CVS repository is not compatible as it has not been
updated to support AviSynth 2.6. AviSynth 2.5 is not supported by Libav.
Once you have the appropriate header, pass <code>--enable-avisynth</code> to
configure to enable AviSynth support.
</p>
<p>For Windows, supported AviSynth variants are
<a href="http://avisynth.nl">AviSynth 2.6</a> for 32-bit builds and
<a href="http://avs-plus.net">AviSynth+ 0.1</a> for 32-bit and 64-bit builds.
The necessary &lsquo;<tt>avisynth_c.h</tt>&rsquo; header is the variant in the &lsquo;<tt>extras/</tt>&rsquo;
directory of the <a href="https://www.videolan.org/developers/x264.html">x264</a>
source tree. For convenience, this header is also available from a
<a href="https://github.com/qyot27/avisynth_headers">temporary repository</a>
along with an installation routine.
</p>
<p>For Linux and OS X, the supported AviSynth variant is
<a href="https://github.com/avxsynth/avxsynth">AvxSynth</a>.
&lsquo;<tt>avxsynth_c.h</tt>&rsquo; is installed as part of the normal
build routine, as illustrated on
<a href="https://github.com/avxsynth/avxsynth/wiki/System-Setup">AvxSynth&rsquo;s wiki</a>.
(the instructions for compiling its prerequisites are outdated, as FFMS 2.18
or higher is now needed; the list of dependencies to be downloaded from the
repositories is still the same, though).
</p>
<div class="float alert alert-info">
<p>AviSynth and AvxSynth are loaded dynamically.  Distributors can build Libav
with <code>--enable-avisynth</code>, and the binaries will work regardless of the
end user having AviSynth or AvxSynth installed - they&rsquo;ll only need to be
installed to use AviSynth scripts (obviously).
