You will need Qt installed (4.7.3 or later recommended). Qt includes QtWebKit and QML. For more interesting effects (e.g. using WebGL, CSS 3D etc.) you may want to build a more current QtWebKit. You may also want to build QtQuick3D - 3D extensions to QML. WebVfx includes support for QtQuick3D.
WebVfx includes an MLT service that exposes producers, filters and transitions implemented in WebVfx. Install MLT Framework 0.7.2 or greater to build the plugin.
In the webvfx directory run
qmake -r PREFIX=/usr/local and then
PREFIX determines where WebVfx will be installed. If MLT is installed in a non-standard location, you may need to set the
PKG_CONFIG_PATH environment variable to where its pkgconfig file lives, e.g.
The MLT melt command will not work with WebVfx on MacOS because the Qt event loop must run on the main thread. If you set
MLT_SOURCE to the root of your MLT source code directory, then a
qmelt executable will be installed which behaves the same as
melt but works with WebVfx on MacOS. e.g.
qmake -r PREFIX=/usr/local MLT_SOURCE=~/Projects/mlt.
