AviSynth+ is an improved version of the AviSynth frameserver, with improved features and developer friendliness.
Visit our forum thread for compilation instructions and support. The original homepage of the project is not functional at the moment (June, 2018). Development branch: https://github.com/AviSynth/AviSynthPlus/tree/master
Building the documentation:
(note, that the bundled documentation was not following the numerous changes in Avisynth+. You can always check the online documentation at http://avisynth.nl/index.php/Main_Page)
AviSynth+'s documentation can be generated into HTML by using Sphinx.
Make sure that Sphinx is installed. This requires that Python is already installed and the pip tool is available. Sphinx 1.3 is the recommended version.
pip install sphinx
For various Linux distributions, a Sphinx package should be available in the distro's repositories. Often under the name 'python-sphinx' (as it is in Ubuntu's repositories).
There is currently a fallback so that distros that only provide Sphinx 1.2 can still build the documentation. It will look different than when built with Sphinx 1.3, because the theme used with Sphinx 1.3 (bizstyle) had not yet been added to the main Sphinx package.
Building the documentation
Once Sphinx is installed, we can build the documentation.
Headers for applications which dynamically load AviSynth+:
The expected use-case of AviSynth+ is as a dynamically loaded library (using LoadLibrary on Windows or dlopen everywhere else).
Due to this, it's not actually necessary to build the AviSynth+ library itself in order for applications using it this way to find it.
To facilitate this, we offer two ways to install just the headers. The GNUmakefile method has been the way to do so for the past few years, but we also support using CMake to do a limited install as well.
mkdir avisynth-build && cd avisynth-build
cmake ../ -DHEADERS_ONLY:bool=on
-DCMAKE_INSTALL_PREFIX can be used to override the
install location if need be.
Using GNUmakefile (legacy):
To install to a non-standard location:
make install PREFIX=/path/to/location
make uninstall PREFIX=/path/to/location
