sarxos / webcam-capture

The goal of this project is to allow integrated or USB-connected webcams to be accessed directly from Java. Using provided libraries users are able to read camera images and detect motion. Main project consist of several sub projects - the root one, which contains required classes, build-in webcam driver compatible with Windows, Linux and Mac OS, which can stream images as fast as your camera can serve them (up to 50 FPS). Main project can be used standalone, but user is able to replace build-in driver with different one - such as OpenIMAJ, GStreamer, V4L4j, JMF, LTI-CIVIL, FMJ, etc.

Hi @jduke32,

The java.lang.ClassNotFoundException: Unknown points me to the thinking that some class is missing, but since Excelsior cuts out all useful informations it may be almost impossible to find out which one is missing.

Does it have some capabilities to disable obfuscation so we can see stack trace or "real" class name instead of Unknown?
