/**
 * OpenCV demo application in C.
 *
 * Uses the cvbase C module (cvbase.c, cvbase.h).
 *
 * This is just a translation of the C++ example in cvdemo.cpp, cvbase.cpp,
 * and cvbase.hpp.
 *
 * Opens a display window and reads input frames from either a camera or video
 * file.  Processes each frame (no operation by default) and displays the
 * results.
 *
 * Provides basic functions to pause/unpause the live input, emit debugging
 * information for selected frames, and to save both raw capture and processed
 * images.
 *
 * If you have installed opencv libraries system-wide, and have pkg-config
 * (default on most modern Linux, available but not default on Windows and OS
 * X), build like this:
 *
 * gcc -o cvdemo cvdemo.c cvbase.c `pkg-config --cflags --libs opencv`
 *
 * Otherwise, replace the part in backquotes with
 *
 * -Iprefix/include/opencv  -Lprefix/lib -lml -lcvaux -lhighgui -lcv -lcxcore 
 *
 * where prefix is the base path where you installed the opencv development
 * binaries (e.g. /usr/local, or somewhere under your homedir).
 *
 * Tested on:
 *
 * ubuntu 10.04 + opencv 2.1.0 src + libv4l-dev
