  • Compliing OpenCV with FFMPEG failing

    20 mai 2016, par moorej

    I’m trying to install OpenCV 3.1.0 on Ubuntu 14.04 with ffmpeg and python 2.7 support. I’m able to compile with :

    cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local 
    
-D  INSTALL_C_EXAMPLES=OFF -D INSTALL_PYTHON_EXAMPLES=ON 
    
-D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-3.1.0/modules 
    
-D WITH_FFMPEG=OFF -D BUILD_EXAMPLES=ON ..

    But -D WITH_FFMPEG=ON fails with the error :

    /usr/bin/ld: /usr/local/lib/libavcodec.a(avpacket.o): 
    
relocation R_X86_64_32 against `.rodata.str1.1' can not be used when
    
making a shared object; recompile with -fPIC
    
/usr/local/lib/libavcodec.a: error adding symbols: Bad value
    
collect2: error: ld returned 1 exit status

    I’m compiling ffmpeg as well and I’ve looked at a number of posts relating to the problem and attempted to add —enable-pic and —enable-shared along with some other options but I have to admit I’m a bit stupid when it comes to anything compilation related. My process for compiling ffmpeg is below. Please help me with my mess. Thanks !

  • FFMPEG background music

    12 avril 2018, par Muhammad Sanaullah

    I am having a problem adding background music to concat videos, I read online using amerge and loop function can be possible, but i don’t have idea how i can achive that.

    My ffmpeg command, which is working, join video, add watermark, add intro and outro.

  • Linking to ffmpeg libraries fails while installing OpenCV

    12 août 2015, par Serhan

    FFMpeg 2.7.2 and all necessary libav* libraries are installed on my Ubuntu 14.04 machine. However, when I try to install OpenCV 2.4.11 (with FFMpeg enabled), I get the following error :

    /usr/bin/ld: cannot find -lavcodec
    
/usr/bin/ld: cannot find -lswresample
    
/usr/bin/ld: cannot find -lavutil
    
/usr/bin/ld: cannot find -lavformat
    
/usr/bin/ld: cannot find -lavcodec
    
/usr/bin/ld: cannot find -lswresample
    
/usr/bin/ld: cannot find -lavutil
    
/usr/bin/ld: cannot find -lavformat
    
collect2: error: ld returned 1 exit status
    
make[2]: *** [bin/opencv_annotation] Error 1
    
make[1]: *** [apps/annotation/CMakeFiles/opencv_annotation.dir/all] Error 2
    
make: *** [all] Error 2

    I already tried pointing LD_LIBRARY_PATH and PKG_CONFIG_PATH to the locations which contain the FFmpeg libraries. I also tried with OpenCV 3.0 and obtained the same error.

    It seems that there is some kind of incompatibility between these versions of FFMpeg and OpenCV. Is there a workaround for this ?

    EDIT :
    For example locate libavcodec.a outputs :

    /home/guel/cvpr2014/bin/dependencies/ffmpeg-2.4/libavcodec/libavcodec.a
    
/home/guel/cvpr2014/bin/dependencies/lib/libavcodec.a
    
/home/guel/cvpr2014/bin/dependencies/opencv-2.4.9/3rdparty/lib/libavcodec.a
    
/home/guel/ffmpeg_build/lib/libavcodec.a
    
/home/guel/git/ffmpeg/libavcodec/libavcodec.a
    
/home/guel/mplayer/ffmpeg/libavcodec/libavcodec.a
    
/home/guel/projects/mpegflow/dependencies/opencv-2.4.11/3rdparty/lib/libavcodec.a

    So, I have it in multiple places. Is that bad ?
