I have the same trouble

I used the trick but open cv didnt work :S

Also having issues here myself. I've tried every single suggestion in the old Discourse thread linked to earlier, and I've also tried daeva's suggestions, but still I get an Unsatisfied Link Error. I've spent the last few hours installing, removing, rebooting, and reading and have not made any headway :(

Hi i dont understand this step:

then right at the end of the Variable value list type in a ; and then C:\Program Files\OpenCV\bin; ->
 
In this Path i have to JavaFX.

Thanks

I too have spent an unhappy afternoon on this same problem. It seems to have a long history so at least I don't feel alone :)

I'm using Eclipse on a Mac. OpenCV works fine in the Processing IDE, but when I try the same scripts in Eclipse (with a library reference to OpenCV.jar), I get the error:

!!! required library not found : no OpenCV in java.library.path
Verify that the java.library.path property is correctly set and the opencv.framework exists in '/Library/Frameworks' folder

The framework is there, so I'm assuming it has to be something to do with Eclipse's path to it. But how to change that? I've been through all the possible solutions in the old thread http://processing.org/discourse/yabb2/YaBB.pl?num=1238338691/0 with no joy.

Eventually I just gave up and went back to the Processing IDE, where everything works fine.

If anyone has an OSX fix for this, or even an idea of what's going wrong, it would be greatly appreciated.

Hi All!
I spent many days trying to get OpenCv to work on Windows without getting the Hypermedia error.
Here is a list of instructions I have created that worked for me to get openCv to work with Processing on Windows:

- Save all of your working files that you want to keep onto a memory stick.
-Put all programmes and files associated with processing and opencv  on your computer into your recycling bin.
-Reinstall Processing from Processing.org
-Download and place it into your documents folder.
-Go to following page: http://ubaa.net/shared/processing/opencv/ and following link to downloading openCV. You need to download version called release version 1.0 (Direct link: http://sourceforge.net/projects/opencvlibrary/files/opencv-win/1.0/OpenCV_1.0.exe/download).
-Once downloaded, unzip and save to desktop.
-Once unzipped, the installation process should start automatically.
-During the installation process, make sure that you tick the box that says "add path".
-Next go back to the open cv page: http://ubaa.net/shared/processing/opencv/ and download "OpenCv processing library".
-Unzip straight into your "libraries" folder within processing.
-Open up processing folder. go to libraries>openCv.You should see 3 folders called reference, source and library. Create a new folder called "Examples".
-Go back to openCV webpage: http://ubaa.net/shared/processing/opencv/ click on "OpenCv processing examples" Download and save to desktop.
-Open Examples folder and highlight all examples. Press copy and go to your documents>Processing>libraries>openCv>Examples folder and paste the examples in there.
-Reboot your computer and hoepfully it should work!

Hope this helps peeps!

I got the following error when I tried to use opencv/eclipse/processing on mac

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

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

at processing.core.PApplet.run(PApplet.java:1530)

I found a really simple solution that fixed everything instantly. Go to Run --> Run Configurations, open the Arguments tab and under VM arguments type

-d32

Then just hit apply and everything works (it did for me).

I hope this helps someone!

I had a similar problem....it actually ended up being 2 problems:

[1]    64 bitness

 I have a 64bit system and both x64 java and x86 (32bit) java installed. The problem is that x64 java (at least version 1.7.x) places entries in the registry under SOFTWARE/JavaSoft and becomes the default, even if you override PATH and JAVA_HOME in the enviroment. The OpenCV processing library has a 32bit dll precompiled so it will complain with an error saying that it can't load on a IA64/AMD 64 system.
Fortunately, processing.exe (at least version 1.5.x) will look under <processing path>/java first before searching for the defaults...

under Windows 7, this can be fixed this way:

cd <your processing dir, where processing.exe lives>
mklink /d java <path to your 32bit java JDK>

you will need Admin priv. to do this.

Ok, now that's solved and running processing.exe with the debug logging flag shows:

C:\processing-1.5.1>processing.exe --l4j-debug

C:\processing-1.5.1>more launch4j.log


CmdLine:        C:\processing-1.5.1\processing.exe --l4j-debug

[2]  Incompatible with version 2+ of OpenCV

Now trying to run the "blobs" example in processing shows:
C:\processing-1.5.1\modes\java\libraries\OpenCV\library\OpenCV.dll: Can't find dependent libraries

running Dependency Walker (google for it), shows the following dependencies of OpenCV.dll:

CV100.DLL
CXCORE100.DLL
HIGHGUI100.DLL

...obviously version "1" DLLs of OpenCV.

So....seems [2] is irreconcilable with Version 2+ of OpenCV.  The processing library of it probably have to be recompiled and possibly ported to use the version 2 interfaces/DLLs of OpenCV.

I have just bought a new macbook pro retina

I think it has something to with processing 2.0b5 as opencv doesn't even work on my old machine unless I roll back to version 1.5.1

seems to be the Mac equivalent of what I described in [#2]. That is, incompatibility between the dynamic-link (shared) libraries of OpenCV 2.x and the other libraries OpenCV depends on that are installed as a part of Processing 1.5 vs Processing 2
