VLC and vlc-dev are not compatible with opencv4.<br>
<br>
- video_filter/opencv_example.cpp should be rewritten or excluded.
It seems to require objectdetect_c.h, which is not longer part of
opencv.<br>
<br>
- video_filter/opencv_wrapper.c needes to be converted to a cpp
file, to enable cplusplus a.o.<br>
<br>
So I tried to do this with the help of the opencv_example.cpp
file. My knowledge is very smal, but the following patches do not
break my vlc-dev (git/videolan/vlc_branch_master) build anymore.<br>
