  • Demande de création d’un canal

    12 mars 2010, par

    En fonction de la configuration de la plateforme, l’utilisateur peu avoir à sa disposition deux méthodes différentes de demande de création de canal. La première est au moment de son inscription, la seconde, après son inscription en remplissant un formulaire de demande.
    Les deux manières demandent les mêmes choses fonctionnent à peu près de la même manière, le futur utilisateur doit remplir une série de champ de formulaire permettant tout d’abord aux administrateurs d’avoir des informations quant à (...)

  • 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.

  • 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 ?

    it works when i type -D WITH_FFMPEG=OFF
