  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • ffmpeg link error with CodeBlocks

    12 juillet 2016, par Yoohoo

    Hi，I am currently doing a real time video encoding c program using ffmpeg, initially I encountered a lot of "undefined reference" error, after I set the linker in build options, some error got disappeared, but still some error remains.

    Here are my screen shot of the CodeBlock linker setting.

    ffmpeg_build/lib/libvpx.a
    
ffmpeg_build/lib/libswscale.a
    
ffmpeg_build/lib/libwresample.a
    
ffmpeg_build/lib/libpostproc.a

ffmpeg_build/lib/libvformat.a
    
ffmpeg_build/lib/libavfilter.a
    
ffmpeg_build/lib/libavdevice.a
    
ffmpeg_build/lib/libavcodec.a

    Totally 10 libs.

    My Questions :

    1. Are these errors caused by lacking libs or libs not linked.
    2. What libs I missing or what libs should I add to linker.

  • Invoking ffmpeg from Java correctly

    10 mars 2015, par Srinivas Suresh

    I would like to call on ffmpeg to split a video into frames, I used

    Process p=Runtime.getRuntime().exec("ffmpeg -i /home/video.mp4 -t 100 -filter:v \"fps=fps=60\" /home/%d.jpeg");
    
p.waitFor();

    But I don’t get the desired result. Nothing happens to the video. How do invoke ffmpeg from java correctly

    EDIT

    Additionally when I invoke ffmpeg without any arguments that have quotes in them it works fine.

    Why is this getting voted down ??
