VideoJack is a mechanism to route video signals between applications running on the same computer.
It enables users of "jackified" video processing software to publish and receive video livestreams.
The current proposal is based on an extended version of the Jack audio server. In the GNU/Linux audio developer community,
the Jack server is kind of an informal standard for realtime audio data exchange.
An improved Jack system with videowires tries to be the same in the videoworld.
