OpenCV library installation problems
Mar 29^th, 2009, 7:58am

I have been try to get my OpenCV library to work, and although Processing seems to recognize it, and is even able to import it,
I get:

>

!!! library OpenCV not found

Exception in thread "Animation Thread" java.lang.UnsatisfiedLinkError: hypermedia.video.OpenCV.capture(III)V

>
This happens when I try to use my OpenCV object:

opencv.capture( width, height );

Hello, recently also I tried to install the OpenCV library in Windows, it generated the same error that they describe to me, nevertheless are archives DLL, that noncopy in the system folder, and that must manually be copied, now I do not have the list of archives that must be copied, but the reason is that. I tomorrow hope to place the archives to them that are required to copy.

After to look for the archives of the OpenCV, I have the list, these archives must be copied in the folder " system32".

cv100.dll
cvaux100.dll
cvcam100.dll
cxcore.dll
cxts001.dll

These archives are created when the OpenCV installs, I do not have the original direction but with the names they are possible to be found.

I'm having the same problem. I'm using a linux machine (Ubuntu 8.10). Any suggestions I've been trying to get this to work for a few days now.

yes, this is frustrating.
i am trying to get it working on windows machine but with no success. i also tried using eclipse and i get the same error all the time.
processing imports the library but as soon as i try to make an instance of
OpenCV object and use opencv.movie( "movie.avi", width, height ); i get:

!!! required library not found : E:\processing-1.0.1\libraries\OpenCV\library\OpenCV.dll: Can't find dependent libraries
Verify that the java.library.path property is correctly set and the '\path\to\OpenCV\bin' exists in your system PATH

Also having a similar problem reading the OpenCV library on Mac OSX despite having the library correctly installed.

I get a error saying Unsatisfiedlinkerror: Capture

Then this is the error log:

!!! required library not found : /Users/tegabrain/Documents/Processing/libraries/OpenCV/library/libOpenCV.jnilib:

Verify that the java.library.path property is correctly set and the opencv.framework exists in '/Library/Frameworks' folder

I made it work under Linux, it's probably not the best solution but it works... I wrote a bit about this in my blog http://walkintothefuture.blogspot.com/2009/04/opencv-java-linux.html
