FreeJ - realtime video processing

freej [ options ] [ files and video devices ]

FreeJ is a digital instrument for video livesets, featuring realtime rendering of multilayered video and chained effect filtering directly on the screen. FreeJ threats every video source as a layer, making then possible to dynamically apply on each a chain of filters, loadable as effect plugins and easily customizable. Layers are implemented to mix together live inputs (video4linux devices), DIVX/AVI files (with avifile library), PNG images and text files word by word.

FreeJ is being developed in the hope to provide the free software community with a modular and highly customizable application for realtime video manipulation; a free and open framework that lets anybody implement hisown filters concentrating simply on the dsp algorithm developed and furthermore to combine them over any supported layer.

FreeJ is a software written in C, C++ and a bit of assembler, it can run on GNU/Linux platform and it could be ported to other platforms; his sourcecode is released under the Gnu Public License, it comes with absolutely no warranty, and you are welcome to redistribute it under certain conditions (refer to the license for details).

FreeJ development is supported by the Nederlands Instituut voor Mediakunst - Montevideo/Time Based Arts.

FreeJ supports an infinite number of layers, as much as your CPU can handle. They can be layers of different types, depending on how you (or your distribution) compiled this software: if any layer format is missing then you can still make it work recompiling FreeJ from the sources after installing all necessary libraries.

Supported layers include:

AVI (*.avi|*.asf|*.asf|*.wma|*.wmv|*.mov|*.mpeg)

depends from avifile library http://avifile.sf.net

TXT (*.txt)

depends from freetype library http://freetype.org
