There is nothing high-tech in this problem. You are trying to use non-existing
VideoCapture
constructor. Wasn't that quite obvious from the error message? You are trying to pass some mysterious argument of the string type, "video path", hard to understand for what purpose.
If you look at the original OpenCV documentation, you will find only two constructors, one without parameters, another one expecting
int
parameter:
http://docs.opencv.org/java/org/opencv/highgui/VideoCapture.html[
^].
That's all.
