问题描述
我尝试使用opencv java接口捕获视频，我发现isOpened总是假的。
I tried to use opencv java interface to capture the video, I find isOpened is always false.
我尝试过不同的视频格式和不同的版本（2.4.11和3.0.0），都遇到了同样的问题。
I have tried different video format and different version (2.4.11 and 3.0.0), both met the same issues.
我已配置-Djava.library.path = D：\Project \opencv \ openncv3。 0\build\x64\vc12\bin，并将opencv_java300.dll复制到此文件夹。
I have configure "-Djava.library.path=D:\Project\opencv\opencv3.0\build\x64\vc12\bin", and have copied opencv_java300.dll to this folder.
我检查了提示和，对我来说都不适用。
And I checked tips OpenCV 3.0 VideoCapture doesn't open video file in Java and OpenCV 2.4 VideoCapture not working on Windows, neither works for me.
任何人都知道捕获视频的技巧部分是什么？
Anyone knows what's the trick part to capture the video?
我的示例代码是：
VideoCapture capture=new VideoCapture();
capture.open("D:\\StopMoti2001.mpeg");
if(!capture.isOpened()){
return;
}
推荐答案
我遇到了同样的问题但感谢你的评论，我已经弄清楚了。对于对解决方案感兴趣的任何人：
将opencv / build / java / x64文件夹中的opencv_ffmpeg310_64.dll复制到项目主文件夹（包含文件夹：src，.settings，bin）。
I have had the same issue but thanks tou your comments I have figured it out. For anyone intrested in the solution:copy opencv_ffmpeg310_64.dll from opencv/build/java/x64 folder to your project main folder (containing folders: src, .settings, bin).
