Javacv UnsatisfiedLinkError in windows 7

Question

In my project I want to capture image from my webcam.

I configured step by step following the instructions from this "OpenCV-JavaCV : eclipse project configuration windows 7" blog post.

After configuration is finished, i tested samples codes and the application found my webcam

SETUP: Setting up device 0

SETUP: Namuga 1.3M Webcam

SETUP: Couldn't find preview pin using SmartTee

SETUP: Capture callback set

SETUP: Device is setup and ready to capture.

and then i got an error which is .dll error.

I use windows 7 x64.

Answer 1

Check whether your Opencv version and JavaCv versions are matching each other. You can check that on the readme file on javacv-bin it specifically say about the required version of the opencv.
