OpenCV-2.3.1 and FFmpeg-2.1.2 compilation and installation on CentOS

OpenCV-2.3.1 and FFmpeg-2.1.2 compilation and installation on CentOS

Tested environment:

1. CentOS 6.3 32bit
2. CentOS 6.5 64bit

I have installed OpenCV in CentOS 6.3 32bit. For more information, see install OpenCV2.3.1 in CentOS 6.3 (see). Now I have changed the 64 bit system and tried it again.

Check and install related programs to ensure that gtk is successfully installed. Otherwise, the image cannot be displayed.

Yum install gcc-c ++ # g ++ Compilation
Yum install gtk-devel # It is actually gtk-devel, not necessarily gtk-devel. You can use * gtk-devel * to match
Yum install gimp-devel
Yum install gimp-devel-tools
Yum install gimp-help-browser
Yum install zlib-devel
Yum install libtiff-devel # tiff Format Image Support
Yum install libjpeg-devel # jpeg Image Support
Yum install libpng-devel # png Image Support
Yum install gstreamer-devel # process multimedia data in MP3, Ogg, MPEG1, MPEG2, AVI, and other formats
Yum install libavc1394-devel #1394 audio interface control command set
Yum install libraw1394-devel
Yum install libdc1394-devel

Yum install swig
Yum install python # python Environment Support
Yum install libtool
Yum install nasm # Assembly Tool

Install ffmpeg2.1.2

Ffmpeg does not have ready-made rpm packages for CentOS. Therefore, you must use the source code for compilation and installation,

./Configure -- enable-shared-disable-yasm
Make
Make install

In this case, ffmpeg is installed under/usr/local by default.

Install OpenCV-2.3.1
1.
Use VI to open the cmakelists.txt file, find the following line, and comment it (#)

Set_property (CACHE CMAKE_BUILD_TYPE property strings $ {CMAKE_CONFIGURATION_TYPES })
# Set_property (CACHE CMAKE_BUILD_TYPE property strings $ {CMAKE_CONFIGURATION_TYPES })

2.
Use VI to open the cmakelists.txt file, search for the keyword ffmpeg, and find the corresponding location,

If (EXISTS/usr/include/ffmpeg/libavformat/avformat. hOR HAVE_FFMPEG_SWSCALE)

Make sure that the directory above is/usr/include. If the path is modified when ffmpeg is installed, modify the directory accordingly.
