trying to install opencv on my centos6and always got this error meesagefatal error: sys/videoio.h: No such file or directory#include <sys/videoio.h>Anybody understand what sys/videoio.h is? where do I get a file like this one?
what is sys/videoio.h?
video;ffmpeg;opencv
Here it is a workaround by deselecting WITH_V4L and selecting WITH_LIBV4L in cmake-gui which  stop checking for sys/videoio.h.Again,same as other solutions I posted, I do not known why it is working this way.
