The Voctomix Project by the C3Voc (the Chaos Communication Congress' Video
Operation Crew) is their software implementation of a Live-Video-Mixer.
It is written in Python using GStreamer and consists of three parts:
- Voctocore, the videomixer core-process that does the actual video- and
- Voctogui, a GUI implementation in GTK controlling the core's functionality
and giving visual feedback of the mixed video.
- Voctomix Example Scripts, a collection of tools and examples for talking
to the core-process, feeding and receiving video-streams and controlling
operations from scripts or command-line.
