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

Answer 1

I faced this problem on Windows XP and Windows 7, and this is how I fixed it on both platforms, using Netbeans 7.2:

Install all required software:

• FFmpeg (32-bit shared): Zeranoe FFmpeg offers win32 builds. Download and extract ffmpeg-20121020-git-04bf2e7-win32-shared.7z. Place its content at C:\ffmpeg.

Note: make sure C:\ffmpeg\bin is a valid path.

• OpenCV 2.4.2 (32-bit): download OpenCV-2.4.2.exe and extract it. Place its content at C:\opencv.

Note: make sure C:\opencv\build\x86\vc10\bin is valid path.

• JavaCV 0.2: download javacv-0.2-bin.zip and extract it. Move the extracted folder to C:\javacv-bin.

• Microsoft Visual C++ redistributable package (32-bit): download and install vcredist_x86.exe.

Configure the environment:

• Edit the environment variable PATH and append the following paths at the end:

C:\ffmpeg\bin;C:\opencv\build\x86\vc10\bin

Now you ready to create a new Netbeans project and test your application. But before you compile it,dDon't forget to right-click the Libraries folder at the pProjects window* and click Add Jar/FOLDER to select all the .jar files located at C:\javacv-bin.
