Hi excuse me if this is not the place to post this issue, I have jus clone the repository and built the it on Mac os Yosemite and the VideoWriter class still does not appear in the java jar.
I followed the instructions on this page http://blogs.wcode.org/2014/10/howto-install-build-and-use-opencv-macosx-10-10/ to install opencv on my device. I appreciated any help with this.
