"unsatisfiedlinkerror: hypermedia.video.OpenCV.capture(III)V" HELP!

in Contributed Library Questions • 3 years ago

Hi all! I`m really new to processing and I´m trying to work with the OpenCv library but after installing and downloading the library to processing and the examples I can't run anything using this library. I keep getting this error "unsatisfiedlinkerror: hypermedia.video.OpenCV.capture(III)V". I've tried some of the suggestions in different forums but didn't work. I'm using processing 1.2.1 and OpenCv2.0 on windows vista... any ideas please?

Have you updated the system path? Which version of OpenCV did you install?

Hey! thnx for answering!! I uninstalled the openCV 2.0 and installed the openCV 1.0 I followed all the recommendations from the Opencv website, and checked that the system path was updated... but I still got an error only this time even more complicated when I tried to run one of the OpenCv examples.
This is what I got:

OMP abort: Initializing libguide.lib, but found libguide40.lib already initialized.
This may cause performance degradation and correctness issues.
Set environment variable KMP_DUPLICATE_LIB_OK=TRUE to ignore
this problem and force the program to continue anyway.
Please note that the use of KMP_DUPLICATE_LIB_OK is unsupported
and using it may cause undefined behavior.
For more information, please contact Intel(R) Premier Support.

I found this solution online

To prevent this, set the Windows Environmental Variable for KMP_DUPLICATE_LIB_OK to TRUE.

For Windows Vista

Click Start > Control Panel.
Click System and Maintenance > System, and then click Advanced Settings in the left pane.
Click Environmental Variables at the bottom of the dialog box.
In the User Variables section, click New.
Type the variable name KMP_DUPLICATE_LIB_OK (type as shown).
Type the variable value TRUE and click OK.
In the System Variables section, click New.
Type the variable name KMP_DUPLICATE_LIB_OK(type as shown).
Type the variable value TRUE and click OK.
Click OK to close Environmental Variables.
Click OK again to close System Properties.

I tried it and it worked now I don´t get any error message buuuuut I'm not getting any video from my camera when I run the OpenCv examples.

I can´t believe it!! any idea why this happens.... I try my camera and it works with the processing video library but I get no image with the OpenCv examples

As I know, openCV 2.0 doesn't support Processing. Try 1.0 version only. Read Opencv install recomendations carefully

I have been trying on and off for a year to get
OpenCV working with Processing sketches on Windows XP

I always get:

The package “Hypermedia” does not exist etc etc warnings on compile.

I have tried all the suggestions on this thread and the old forum thread:
http://processing.org/discourse/yabb2/YaBB.pl?num=1238338691/0

I have tried to get it working on 4 on four different Windows XP machines,
with OpenCV_1.0.exe and OpenCV_1.1pre1a.exe
tried tweaking the environment variables, tried dropping dlls into all manner
of locations......

I can’t get the darn thing to work, and I have spent days trying......

Is anyone clever enough to have a solution?
Maybe someone who has got it working could give more in-depth info on their system settings.

So you've manually updated the path variable? That definitely seems to be a major cause of problems.

One other possibility to consider is your webcam. I recently tried running openCV with an old digital camera with built-in webcam functionality (on Windows 7) and encountered similar errors. I got myself an up-to-date webcam and it ran no problem at all....

Hi blindfish, yes i tried updating the path... even tried placing the dlls in different folder and each time it was a failure... I tried in a different laptop with windows 7 (I had tried in vista before) and I got the exact same results... So far best outcome with Opencv has been to not get an error message but just a black screen and no video after running processing. I found at the processing old forum a solution to the black screen / no video signal without error messsage appearing after run the face resolution example and after updating / linkg the haarcascades...xml (which apparently is another bug with Opencv)

envy44 replied to the post OpenCV capture hang under Windows XP/Vista/7 with: "So I create a Capture and OpenCv, and then I copy the capture's stream into the Opencv."

Which is basically putting the Opencv code into a sketch that uses the processing video library to do the video capture... :S

I'm not so happy about this solution because i feel can´t rely on a library that is only working half way... and this also adds to your point of it being a camera issue so I will try it out with another camera a newer one and one that is not built-in and hopefully that will be the final solution...

cheers and thnx!

I got the same error too.

My platform is mac mountain lion and using processing 2.0b5

import hypermedia.video.*;

OpenCV opencv;

void setup()

{

size( 640, 480 );

opencv = new OpenCV( this );

opencv.capture( width, height );

}

void draw()

{

opencv.read();

opencv.flip( OpenCV.FLIP_HORIZONTAL );

image( opencv.image(), 0, 0 );

}

But it show an error

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

Anyone know how to solve this.
