    Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
    Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

  • ffmpeg how to ignore (skip) errors when concatenate and speed up multiple video files

    3 avril 2016, par user1767834

    I’m trying to concatenate many files from my car DVR but some time ffmpeg fails with "Invalid argument" error.
    My list of files in cf.txt looks like :

    file '2016_0403_170004_098.MOV'
    
file '2016_0403_170459_099.MOV'
    
file '2016_0403_170630_100.MOV'
    
...

    And I run ffmpeg using next command :

    ffmpeg -f concat -i cf.txt -qscale:v 0 -filter:v "setpts=0.05*PTS" -an e:\MOVIE\all.mov

    After some outputs ffmpeg crushes with message :

    Output #0, mov, to 'e:\MOVIE\all.mov':

    See line :

    cf.txt : Invalid argument

    So, I want to ignore this error (and any other if possible) and continue to process the files.
    Is it possible ?

  • Compilation of x264 with newest libswscale and libavformat

    4 décembre 2016, par pcroland

    Yesterday I wanted to compile x264 myself because the latest binary on videolan is compiled without libswscale : link

    If I just use

    ./configure --enable-static --enable-shared

    then the binary will compile libswscale 3.1.101 and libavformat 56.40.101 from the libswscale-dev and libavformat-dev packages. If I clone FFmpeg’s git and use

    ./configure --enable-static --enable-shared --extra-cflags="-I$HOME/FFmpeg"

    the binary will have the latest libswscale and libavformat, but it wont work :

  • FFmpeg libx264 Llicense

    2 juillet 2014, par user416472

    We have Java Spring application. The application interacts with FFmpeg through Java Runtime.exec() call in order to encode video into mp4 format. Are we ok with the commercial aspect of our application, having in mind that libx264 is released under GPL license, ffmpeg under LGPL license and we are using ffmpeg as external command line utility already installed and hosted on the client’s computer ?
