  • 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 (...)

  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • ffmpeg - Frames flip upside-down when using -c:v copy

    26 décembre 2019, par Berndi

    I tried to just copy (a period of time of) an AVI-Video into another newly created AVI-file using ffmpeg’s copy option.
    (On Windows 32-bit)

    ffmpeg -i "C:\Temp\zzz\myAvi.avi" -c copy -t 00:00:10 "C:\Temp\zzz\myAviNew.avi"

    Why are the pictures flipped upside-down in the resulting file ?
    (Also the generated new audio is a little distorted.)

    Using the same command again on the newly created file will not flip them back again - the pictures stay upside down.
    Why this ? Is it a bug ?

    Console brings the following output :

  • Create 1080p videos with javacv and ffmpeg or alternate lib

    20 novembre 2012, par 501 - not implemented

    is there a option in JavaCV to capture 1080p videos from images ?
    If i use the FFmpegFrameRecorde, i only find 480p.

    Or is there a alternate library for Java ?
    I want to use it to create a video from kind of pictures (with zooming and rotating effects)

    greetings

    //EDIT

    Okay,
    now i've tested a very simple code :

        FrameRecorder  recorder = FFmpegFrameRecorder.createDefault("out.avi", 1920, 1080);
    
    recorder.start();
    
    recorder.record(iplImage);
    
    recorder.stop();

    and it's works ! But the file is very large (10sec around 300MB...)

    Now i want to add a codec like xvid. I've get the following eyxception :

    com.googlecode.javacv.FrameRecorder$Exception: codec not found

    But i've installed the xvid paket. Must i add the codec in a special folder like the ffmpeg bin ?
