There are probably bugs and I'd like to hear about them if you find one.
The latest release now uses V4L2 to support a wider array of modern cameras. Additionally it currently only supports YUYV cameras, which are much more common than the RGB cameras that earlier releases required.
This should work without problems, but use at your own risk.
This release contains a prebuilt .jar and .so so you can start using it right away. The source is also included with build instructions.
Refer to the included README for installation instructions.
A spanish translation of the build and installation instructions is available from Gabriel Zea.
