Easily capture screenshots with this small tool. Teppefall Capture is a convenient software that allows you to take snapshots. Teppefall Capture is a simple Photo Booth clone. By simple I mean it is built on the FX/Layout stack, has an OpenGL powered live preview (JOGL + TextureRenderer) and gets its video feed from a custom video capture library.

These screenshots show Teppefall Capture under the Substance Graphite look and feel running on Windows Vista. The video feed is provided by a JMyron decoder.

This software has something like 30 threads, 10Mb of dependencies and is extremely volatile. It might still be shelved since it has a high number of problematic bugs. This software not only takes down Java VM's... it can crash Windows XP if there is a driver problem. Blue screens for everybody ! This is usually because my primary video decoder is based on Jmyron, which is a native library with zero tolerance for sloppy coding. Just a small change in the threading or start/stop code can crash the entire application.

Capture was built using Teppefall FX/Layout and has only a few lines of JFC/Swing layout code. Everything else is done in Teppefall Layout JFC - my homegrown XML format. The 2D renderer on top was prototyped in Javascript and then converted to Java, but it still runs in the same SurfacePanel component (the one used in FX). I though about compiling the Javascript into a Java renderer, but I doubt it will work as well - or at all. I also need all the performance I can get. I had to do my own hit code for the RSS tag and stuff like that is easy to mess up.

Performance is a big problem in an software like this. The current version eats up 98% CPU when showing a live video feed (no restrictions on FPS or JOGL). Because of this I am forced to shut down the live preview when an image is being written to disk. There might not be enough CPU power available on my machine to do both things at the same time. I am primarily worried that Capture will make media players skip on single core systems. So a lot of thought has to be put into the way you move data around. Telling people that "it works on my system" might not be the best route.

The license of this software is Freeware, you can free download and free use this screen capture software.
