  • 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 vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • Unable to install ffmpeg on CircleCi Ubuntu 14.04

    28 juillet 2017, par Mateusz Urbański

    I have Ruby on Rails project which uses CircleCI for continuous deployment. I’m trying to install ffmpeg because I need this to make all of my specs green. Unfortunately I’m not able to do that. I’ve read a lot of different topics but I didn’t find any solution for that. Currently I’m installing ffmpeg in the following way :

    cd ~/ffmpeg_sources
    
wget http://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2
    
tar xjvf ffmpeg-snapshot.tar.bz2
    
cd ffmpeg
    
PATH="$PATH:$HOME/bin" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure \
    
  --prefix="$HOME/ffmpeg_build" \
    
  --extra-cflags="-I$HOME/ffmpeg_build/include" \
    
  --extra-ldflags="-L$HOME/ffmpeg_build/lib" \
    
  --bindir="$HOME/bin" \
    
  --extra-libs="-ldl" \
    
  --enable-gpl \
    
  --enable-libass \
    
  --enable-libfdk-aac \
    
  --enable-libfreetype \
    
  --enable-libmp3lame \
    
  --enable-libopus \
    
  --enable-libtheora \
    
  --enable-libvorbis \
    
  --enable-libvpx \
    
  --enable-libx264 \
    
  --enable-nonfree \
    
  --enable-x11grab
    
PATH="$PATH:$HOME/bin" make
    
sudo make install
    
sudo make distclean
    
hash -r

    I didn’t see any errors in the console but when I run my specs some of them failing because of missing ffmpeg library. How can I solve this problem ?

    how to build ffmpeg with librist ?

    


    I cannot find any useful thing to do it.

    


    I run a sh file in minGW on Windows as below :

    


    `./configure\
 --prefix=/home/source/ffmpeg/build/ffmepg-5.1\
 --arch=x86_64\
 --enable-shared\
 --enable-gpl\
 --enable-libfdk-aac\
 --enable-nonfree\
 --enable-libvpx\
 --enable-libx264\
 --enable-libx265\
 --enable-libmp3lame\
 --enable-librist\
 --extra-cflags="-I/home/source/build/libfdk-aac/include"\
 --extra-ldflags="-L/home/source/build/libfdk-aac/lib"\
 --extra-cflags="-I/home/source/build/libvpx/include"\
 --extra-ldflags="-L/home/source/build/libvpx/lib"\
 --extra-cflags="-I/home/source/build/libx264/include"\
 --extra-ldflags="-L/home/source/build/libx264/lib"\
 --extra-cflags="-I/home/source/build/libx265/include"\
 --extra-ldflags="-L/home/source/build/libx265/lib"\
 --extra-cflags="-I/home/source/build/libmp3lame/include"\
 --extra-ldflags="-L/home/source/build/libmp3lame/lib"\
 --extra-cflags="-I/home/source/librist/build/include"\
 --extra-cflags="-I/home/source/librist/include/librist"\
 --extra-cflags="-I/home/source/librist/include"\
 --extra-ldflags="-L/home/source/librist/build/"`


    


    the error is :
ERROR : librist >= 0.2.7 not found using pkg-config

    


    If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.libera.chat.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

    


    ==================

    


    I have downloaded the latest librist source code !

    


    if I remove "—enable-librist" , everything is OK, but there is no librist in ffmpeg...
