Dudes, problem solved here!!!
what the problem here I have is, it lack some dll files. I found out Opencv 1.0 need *.dll file both from 1.0 and 1.1 (weird @_@) So, what you have to do is, install 1.1, copy all the *.dll from lib folder to C:\windows\system32\ and then remove 1.1, install 1.0, repeat the same thing, and then it should work. GOOD LUCK guys!!

Mac Intel imac OSX 10.5.6

Hey i have had this problem (and with other libraries before). How i "fixed " with a midi library was to put the library files into a CODE directory in the sketch directory directly. This is incorrect and i have seen one of the founders say that this is not the correct thing to do and that it is mixing up two totally different things. However it did work with the midi library...SO after trying everything else to get the FaceDetection example working i did the same and dropped all the OpenCV files into a CODE directory in the sketch directory. It worked first time !!!!!

If you are desperate to get this working then you can use this method. I think someone really needs to dig deeper into the way processing uses libraries because i have had this problem several times now..

I got it to work with these files (see screenshot) in the root directory of my eclipse folder (which is the current path when it executes a file): ://img529.imageshack.us/img529/8878/opencvfiles.jpg

Dear windows users,

I'm pretty sure I followed the very same steps but I still get:

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

I'm just using processing on Vista 64 (not Eclipse or cool stuff like that) if that makes a difference.

Could someone please summarize an (dummy-proof) installation approach that definitely works at a system level (not by having the dlls in the project path) ?

Any help would truly be more than welcome as my hair loss rate is beating new records by the minute.

I went the brute force way and put ALL the DLLs in one place. Added that path to the the system env path variable. And bingo. Phew, someone at openCV megalabs could have made it a bit easier but hey, I'm so happy it's working now that he/she is easily forgiven.

I fought with this problem all afternoon, and after doing what this guy did (he's on Windows Vista, but I'm on XP) it now works... not sure why... but it does.

The other thing that I did was copy OpenCV.dll into the OpenCV/bin folder AS WELL AS WINDOWS/system32 which may have also solved the problem.

Hello guys!

Just to thank everybody for the useful discussion. I've encountered the same installation problem (the message from processing was: UnsatisfiedLinkError: hypermedia.video.OpenCV.capture(III)V) using a windows XP machine. I solved it following edion's instructions, simply copying the OpenCV.dll into the OpenCV/bin folder AS WELL AS in the WINDOWS/system32 folder.
