Koen Kooi 888509e75f opencv, opencv-samples: add 2.4.2
Libav is easier to get right than gstreamer, so switch back. Also enable libv4l for better v4l(2) support

Subject: [PATCH] Fix CMakeLists.txt numpy detection
Right now, the code opencv uses to detect where the numpy include files are doesn't work with cross-compiling because it uses the native python to determine the environment. To make this a little better, allow the user to explictly specify the path using -DPYTHON_NUMPY_INCLUDE_DIRS=path/to/numpy/include/dir .
