Frei0r is a minimalistic plugin API for video sources and filters. The behavior of the effects can be controlled from the host by simple parameters. The intent is to solve the recurring reimplementation or adaptation issue of standard effects. It is not meant as a generic API for all kinds of video applications.
frei0r plugins are used by several projects (e.g.: LiVES, Veejay, Open Movie Editor, FreeJ, Pure Data Visual Junk Tools, MLT framework).
This package contains a collection of plugins.
