A video mixer [1] is used to select one or many video streams from different video sources
and mix them together to form a single video output. The currently available video mixers
use specific hardware devices of very high cost. Our solution "Chamelean" is a cost
effective real-time video mixing and broadcasting software which can run on a regular
personal computer using generic devices. Chameleon performs the mixing of multiple
video streams such as applying transitions from one video to another, alpha blending of
multiple video streams and compositing videos within each other as well as applying text,
effects and images to videos
