Ahem...

as you can see I have experimented with glc before. Unfortunately it still
shows the program on the screen. But yes it can be used to capture/display
any openGL program in LiVES. I have used it before to capture clips from
Second Life for example. So that is one possibility that can be done
already but it is not ideal.
Yesterday I tested running projectM in a framebuffer X (Xvfb), but it did
not work - the first thing that projectM does is to check the openGL
extensions, which makes it crash since the framebuffer doesn't have any...
I think that best solution is to create the window and hide it. This can
even be done at startup time if the projectM wrapper is loaded. SDL 2.0 has
a function for this, but SDL 1.2 which projectM uses does not. So basically
I tried messing with X directly (XUnmapWindow) but for some reason my first
test crashed in that function. Anyway I will keep on trying via this route.

Gabriel.
