Answer 1

I had the exact same issue using Manjaro 17.0.2 and OpenCV 3.2.0 with Java. I removed the old implementation of OpenCV, went and reinstalled it from scratch. Ran cmake with these parameters cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_LIBV4L=ON .. (thanks @emre)

Then in the output of the Cmake installation I noticed Can't find ffmpeg - 'pkg-config' utility is missing. Installed the pkg-config and re ran cmake, make and now everything works.
