libconfig
Download ffmpeg from http://ffmpeg.mplayerhq.hu/download.html. 11 The ffmpeg program has a lesser general public license (LGPL). To use it with non-GPL software (such as OpenCV), build and use a shared ffmpg library: $> ./configure --enable-shared $> make $> sudo make install You will end up with: /usr/local/lib/libavcodec.so.*, /usr/local/lib/libavformat.so.*, /usr/local/lib/libavutil.so.*, and include files under various /usr/local/include/libav*. To build OpenCV once it is downloaded: 12 $> $> $> $> mkdir build && cd build cmake .. && make sudo make install sudo ldconfig After installation is complete, the default installation path is /usr/local/lib/ and /usr/local/include/opencv2/. Hence you need to add /usr/local/lib/ to /etc/ld.so.conf (and run ldconfig afterwards) or add it to the LD_LIBRARY_PATH environment variable; then you are done.
