The Installation Procedure
To install and configure OpenCV 2.4.1, complete the following steps.
The commands shown in each step can be copy and pasted directly into a
Linux command line.
Remove any installed versions of ffmpeg and x264.
sudo apt-get remove ffmpeg x264 libx264-dev
Get all the dependencies for x264 and ffmpeg.
sudo apt-get update
sudo apt-get install build-essential checkinstall git cmake libfaac-dev libjack-jackd2-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libsdl1.2-dev libtheora-dev libva-dev libvdpau-dev libvorbis-dev libx11-dev libxfixes-dev libxvidcore-dev texi2html yasm zlib1g-dev
Download and install gstreamer.
sudo apt-get install libgstreamer0.10-0 libgstreamer0.10-dev gstreamer0.10-tools gstreamer0.10-plugins-base libgstreamer-plugins-base0.10-dev gstreamer0.10-plugins-good gstreamer0.10-plugins-ugly gstreamer0.10-plugins-bad gstreamer0.10-ffmpeg
Download and install gtk.
sudo apt-get install libgtk2.0-0 libgtk2.0-dev
Download and install libjpeg.
sudo apt-get install libjpeg8 libjpeg8-dev
Create a directory to hold source code.
cd ~
mkdir src
Download and install install x264.
Download a recent stable snapshot of x264 from ftp://ftp.videolan.org/pub/videolan/x264/snapshots/. The exact version does not seem to matter. To write this guide, I used version x264-snapshot-20120528-2245-stable.tar.bz2, but I have used previous versions too.
cd ~/src wget ftp://ftp.videolan.org/pub/videolan/x264/snapshots/x264-snapshot-20120528-2245-stable.tar.bz2 tar xvf x264-snapshot-20120528-2245-stable.tar.bz2 cd x264-snapshot-20120528-2245-stable
Configure and build the x264 libraries.
./configure --enable-static
make
sudo make install IMPORTANT: If you are running a 64-bit version of Ubuntu, you must configure x264 as shown in the following command: ./configure --enable-shared --enable-pic The -shared and -pic options might also be required when you compile for some other architectures, such as ARM. You know you need these options if you get the following error when compiling OpenCV:
[ 25%] Building CXX object modules/highgui/CMakeFiles/opencv_highgui.dir/src/bitstrm.cpp.o
