====== Duga, a live video streamer ======

Duga is a tool that combines multiple video and audio streams from cameras, microphones, files and static images. It is intended for streaming lectures in [[http://jenda.hrach.eu/f/00000001.jpg|format similar to DefCon]], where you need to mix slides, the speaker and the audience.

Duga will be integrated to [[project:presentationcenter:start]] to stream future [[:video:start|brmlab lectures]].

Highlights:

  * Add and remove streams runtime.
  * Combine and switch multiple sources, put them side-by-side or [[https://en.wikipedia.org/wiki/Picture-in-picture|picture-in-picture]].
  * Graceful error handling (missing frames, desynchronized clock, accidentally disconnected cameras…)
  * Adjust brightness, contrast, volume level.
  * Script-friendly text-based configuration and control.

The following image shows video from a webcam, a small video of kittens (which is definitely important) from a file and brmlab logo overlay with demonstration of smooth alpha compositing (the blue strip).

===== TODO =====

  * test it with various video and audio sources to see if it is stable and if some A-V sync will be needed
  * maybe add TCP server for controlling via socket?
