Then pass @code{--enable-libilbc} to configure to enable it. +@section AviSynth + +Libav can read AviSynth scripts as input. To enable support you need a +suitable @file{avisynth_c.h} header to compile against. The header in +classic AviSynth'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} to +configure to enable AviSynth support. + +For Windows, supported AviSynth variants are +@url{http://avisynth.nl, AviSynth 2.6} for 32-bit builds and +@url{http://avs-plus.net, AviSynth+ 0.1} for 32-bit and 64-bit builds. +The necessary @file{avisynth_c.h} header is the variant in the @file{extras/} +directory of the @url{https://www.videolan.org/developers/x264.html, x264} +source tree. For convenience, this header is also available from a +@url{https://github.com/qyot27/avisynth_headers, temporary repository} +along with an installation routine. + +For Linux and OS X, the supported AviSynth variant is +@url{https://github.com/avxsynth/avxsynth, AvxSynth}. +@file{avxsynth_c.h} is installed as part of the normal +build routine, as illustrated on +@url{https://github.com/avxsynth/avxsynth/wiki/System-Setup, AvxSynth's wiki}. +(the instructions for compiling its prerequisites are outdated, as FFMS 2.18 +or higher is now needed; the list of dependencies to be downloaded from the +repositories is still the same, though). +@float NOTE +AviSynth and AvxSynth are loaded dynamically. Distributors can build Libav +with @code{--enable-avisynth}, and the binaries will work regardless of the +end user having AviSynth or AvxSynth installed - they'll only need to be +installed to use AviSynth scripts (obviously). +@end float @chapter Supported File Formats and Codecs |
