install OpenCV Looking for ffmpeg/avformat.h - not found
Hi,
I try to install OpenCV from ffmpeg. Some errors happen.
OS: Centos 6, 64bit
The ffmpeg has been already installed via following commands.
1)download ffmpeg-0.11.1.tar.gz
2)uncompress
3)su and cd .....
4)./configure --prefix=/usr --enable-shared --disable-yasm
5)make
6)make install
Then I install OpenCV as following commands.
1) download OpenCv-2.4.1.tar.bz2
2) uncompress
3) su and cd ...
4) modify CMakeLists.txt
a: commend on the sentence " set_property( CACHE CMAKE_BUILD_TYPE PROPERTY STRINGS ${CMAKE_CONFIGURATION_TYPES} )"
b: change "set(CMAKE_INSTALL_PREFIX "/usr/local" CACHE PATH "Installation Directory") " to "set(CMAKE_INSTALL_PREFIX "/usr" CACHE PATH "Installation Directory") "
5) mkdir release
cd release
cmake ../
6) make
Here errors happen. It said that "../../lib/libopencv_highgui.so.2.4.1: undefined reference to `avformat_find_stream_info' ...". And I noticed that "libavformat/avformat.h - found" appears after running "cmake ../". I am stumped. Would any one help me fix this problem? Thanks.
