install ffmpeg

1.下载源文件

http://ffmpeg.org/releases/ffmpeg-1.2.1.tar.bz2

2.解压：

tar xvjf ffmpeg-1.2.1.tar.bz2

3.配置ffmpeg:

./configure --enable-shared  --prefix=/usr --disable-yasm

make

sudo make install

cd /usr/include
sudo mkdir ffmpeg

cp -r libav* libsw* ffmpeg

因为opencv config在这里检查是否安装ffmpeg

install opencv

conda install -c https://conda.binstar.org/menpo opencv

conda install -c https://conda.binstar.org/jaimeivancervantes opencv   #with ffmpeg

conda install -c https://conda.anaconda.org/groakatffmpeg-dev

下载OpenCV

#切换到家目录
cd ~ 
#使用wget下载 Opencv-2.4.9
wget http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.4.9/opencv-2.4.9.zip   
#解压          
unzip opencv-2.4.9.zip      
#转到解压目录    
cd opencv-2.4.9

编译

#创建编译目录
mkdir build

#转到编译目录下    
cd build

#设置编译参数

cmake -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON -D WITH_VTK=ON -D CUDA_GENERATION=Auto ..

开始编译OpenCV-2.4.9

make
sudo make install

配置环境变量

配置OpenCV库引用(类似于windows环境变量)

sudo gedit /etc/ld.so.conf.d/opencv.conf

添加下面一行在文件末尾（它可能是一个空文件，这是确定的），然后将其保存：

/usr/local/lib

输入下面的命令使其生效

sudo ldconfig

打开另一个文件

sudo gedit /etc/bash.bashrc

添加这两行的文件的末尾并保存：

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH
