3. Install ffmpeg

(1) wgethttps: // www.ffmpeg.org/releases/ffmpeg-2.8.tar.gz

(2) tar zxvf ffmpeg-2.8.tar.gz

(3) cd ffmpeg-2.8

(4) PKG_CONFIG_PATH =/usr/local/ffmpeg_build/lib/pkgconfig

Export PKG_CONFIG_PATH

(5 ). /configure ---- prefix = "/usr/local/ffmpeg_build" -- extra-cflags = "-I/usr/local/ffmpeg_build/include" -- extra-ldflags = "-L/usr /local/ffmpeg_build/lib "-- bindir ="/usr/local/bin"

-- Extra-libs =-ldl -- enablel-shared -- enable-gpl

. /Configure-prefix = "usr/local/ffmpeg_build"-extra-cflags = "-I/usr/local/ffmpeg_build/include" -- extra-ldflags = "-L/usr/ local/ffmpeg_build/lib "-- bindir ="/usr/local/bin "-- extra-libs =-ldl -- enablel-shared -- enable-gpl

Make-j8

(7) makeinstall

(8) cd/etc/bashrc

Add

ExportPKG_CONFIG_PATH =/usr/local/ffmpeg_build/lib/pkgconfig: $ PKG_CONFIG_PATH

ExportLD_LIBRARY_PATH =/usr/local/ffmpeg_build/lib: $ LD_LIBRARY_PATH

(9) Enter ffmpeg on the terminal

4. Install opencv

(1) unzip opencv-2.4.9.zip

(2) cd opencv-2.4.9.zip

(3) mkdir build

(4) cmake-D CMAKE_BUILD_TYPE = RELEASE-D CMAKE_INSTALL_PREFIX =./build/../opencv-2.4.9

(5) make-j8

(6) make install

(7) input at the terminal

ExportLD_LIBRARY_PATH =/usr/local/opencv-2.4.9/build/lib/: $ LD_LIBRARY_PATH

Or run vim/etc/ld. so. conf.

Add at the end of the file

/Usr/local/opencv-2.4.9/lib

Enter ldconfig on the terminal

(8) run the following command:

Cp/usr/local/opencv-2.4.9/lib/pkgconfig/opencv. pc/usr/lib64/pkgconfig/

Copy/usr/local/opencv-2.4.9/lib/pkgconfig/opencv. pc to/usr/lib64/pkgconfig/

Postscript:

Since we used opencv on windows, we started to use Opencv from windows to linux servers for project purposes. Although it is very easy to install opencv on centos, however, I have been tossing for several days. The main reason is that the related functions in CvCapture cannot be used to determine whether or not the installation packages are not installed, which video-related installation packages are missing, and we have not found out. I will try again later.
