Error running program for Processing

I can not run OpenCV for Processing in Windows 7.

I have this error all the time, even with the examples:

UnsatifiedLinkError:hypermedia.video.OpenCV.capture(III)V

I was looking on the internet to find the solution, it seems a very common error, but no one gives a good answer to what I have to do to solve it. If somebody can help me, please, do it!! I need this for a personal art project in Argentina. Thanks Jimena

That OpenCV library for Processing is very old and hasn't been maintained. I'm not surprised it doesn't work on Windows 7. There are currently two options for working with OpenCV in Processing: JavacvPro and OpenCVPro. JavacvPro is available here (website in French):

http://www.mon-club-elec.fr/pmwiki_reference_lib_javacvPro/pmwiki.php

It requires building opencv on your platform. It uses JavaCPP and JavaCV. It leaks memory.

The other option, OpenCVPro, is a new Processing library I am working on for OpenCV:

http://github.com/atduskgreg/opencvpro

It is very new (I've only been working on it for about a month). And I haven't tested it yet on Windows. However, it is built off of the new officially-supported OpenCV java bindings. If you'd like to help me get it working on Windows it might be a good solution for you. If not, I will likely add basic Windows support in the next month.
