[gephex-devel] Results of Drone's yesterday meeting

Hi Jean-Sebastien

A intensive exchange of ideas and goals will open ways of inter project

My aim is to port all gephex video filters and generators to the frei0r 
api if there is no loose of functionality. Let's hope the main actors in 
the livido api discussion will reach a reasonable consensus soon.

I'm at the moment working on a c++ helper library(just a header) to ease 
implementing effects and to encourage the use C++ for filter development 
instead C.

In my opinion the 0.4 engine would not be worth to fork. As Georg 
already pointed out it is in many ways overengineered. The design of the 
0.5 engine will be a lot simpler and more flexible. There will only a 
"small realtime core" library written in c++. The idea is to make this 
core usable for different high level applications. E.g.

1. a simple battle mixer vj app with two video players and a crossfader.

2. A generic dataflow graphbuilder app similar to the current user 
interface.

As the current ui concept is quite problematic for live usage 
experimenting with different kind of userinterfaces should be as easy as 
possible.

The idea to archive this is to use scheme for gluing the core layer with 
the ui layer.

I'm looking forward to a collaboration of both projects.
