I have followed the instruction from this website http://docs.opencv.org/doc/tutorials/introduction/linux_install/linux_install.html but I ran into the following problems: [ 27%] Building CXX object modules/videoio/CMakeFiles/opencv_videoio.dir/src/cap_ffmpeg.cpp.o In file included from ~/opencv/modules/videoio/src/cap_ffmpeg_impl.hpp:65:0, from ~/opencv/modules/videoio/src/cap_ffmpeg.cpp:45: ~/opencv/modules/videoio/src/ffmpeg_codecs.hpp:171:7: error: ‘AV_CODEC_ID_H263I’ was not declared in this scope ~/opencv/modules/videoio/src/ffmpeg_codecs.hpp:287:7: error: ‘AV_CODEC_ID_WNV1’ was not declared in this scope make[2]: * [modules/videoio/CMakeFiles/opencv_videoio.dir/src/cap_ffmpeg.cpp.o] Error 1 make[1]: [modules/videoio/CMakeFiles/opencv_videoio.dir/all] Error 2 make: ** [all] Error 2
I have searched internet and can't find a solution for that. any comments? thanks.
