Just the same problem like @hepin1989 https://github.com/ochafik/nativelibs4java/issues/364

And my OS is win7 ultimate But, not all the win7 can not work ,just one of mine throw this exception, i don`t know why. Could you help please ??

More thoughts - BridJ can also fail the load because of some libraries missing (not sure about this, need to clarify), so there is a tool called Dependency Walker which allows you to check if all DLL dependencies are available on your PC.

To find the OpenIMAJGrabber.dll you have to open webcam-capture-0.3.10-RC1.jar with e.g. WinRAR and go to the com/github/sarxos/webcam/ds/buildin/lib/win32 and extract OpenIMAJGrabber.dll. Then, when you have itn on your desktop, fire Dependency Walker and go to File / Open, choose extracted DLL and hit Open button.

I also get this issue after trying to git checkout the repo into Eclipse. I test the dev environment by exporting the unedited webcam-capture jar and then use it in an existing project (to test the dev environment before I edit the library) and I get the following printing to console Note the github jar file you can download for webcam-capture-0.3.12.jar works with my existing project just fine but upon Eclipse 09-2022 -> File -> Import -> Git -> Projects from Git (with smart import) -> Clone URI -> URI: https://github.com/sarxos/webcam-capture.git Host: github.com Repository path: /sarxos/webcam-capture.git Protocol: Https -> Branch: Master -> Select All -> Finish -> No visible errors -> then Eclipse -> Export -> Java -> JAR file -> Next -> webcam-capture_webcam-capture -> Finish and upon importing the jar into my working other project (in place of the one available at the repo) I get this error:
