Slideshow Generator

Over the last few days I hacked together a little slide show generator that was inspired by still2dv, but as still2dv was a little to slow to be usable for me, I hacked together my own that can render in realtime using OpenGL. It also supports offline rendering to JPEG files which can then be further processed with mencoder/ffmpeg.

The slideshow generator works by supplying a bunch of JPEG files and a control file, the control file defines what path the camera shall take, how long fadeovers should last and things like that. The control file looks like this:

set fade 2.0
set dt 10.0

fade $fade

image test/screenshot5.jpg
pos center center
zoom fill

duration $dt

pos 60% center
zoom 1.5
end

fade $fade

image test/screenshot6.jpg
pos 60% center
zoom 1.5

duration $dt

zoom fill
end

fade $fade

image test/screenshot7.jpg
zoom fill

duration $dt

pos 40% center
zoom 1.5
end

[...]

An example video produced with the slideshow generator would look like this:



The code for the thing is floating around in the Windstille SVN repository in the directory extra/slideshow/. It is not separated from the whole thing, so you have to grab everything to build it:

svn co svn://svn.berlios.de/windstille/trunk/windstille
