  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • 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 (...)

  • Keeping control of your media in your hands

    13 avril 2011, par

    The vocabulary used on this site and around MediaSPIP in general, aims to avoid reference to Web 2.0 and the companies that profit from media-sharing.

  • Change the framerate of a video including audio without re-encoding using ffmpeg

    12 août 2018, par Trojaner_

    I have a 30.02 FPS .mp4-video and I’m trying to convert it to 30 FPS. I found this question but if I try the method like described in the first answer the audio gets lost because the video is getting converted in a .h264-file which can’t contain audio as I read here.

    (I’m sorry if i’ve got issues with the english language, it isn’t my mother language)

    EDIT : Here goes the content I enter in the terminal and the output that returns

    Input : ffmpeg -y -i 01.mp4 -f h264 -c copy temp1.h264

    Output : (I replaced the real paths with path\to\...)

  • FFMPEG : Generate segments with millisecond precision [on hold]

    10 septembre 2018, par Kalpit

    I’m generating 10s mp3 segments off a local udp stream with

    ffmpeg -i "udp://localhost:5000/live/stream" -f segment -segment_time 10 -map 0:a -strftime 1 "/usr/share/streamed/%Y-%m-%d-%H-%M-%S.mp3"

    However, strftime doesnt seem to support millisecond precision. Is there a way I can generate filenames with millisecond accuracy ? Or is there some alternative way other than building my own ffmpeg ?

    Bah…
    Tu mets : define('_BOUCLE_PROFILER', 5000);
    Ce qui indique de logguer les boucles qui mettent plus de 5s à se calculer.
    Voilà… ton log indique que la boucle des résultats de recherche de plugins met 184s à se faire.
    En fait c’est très long car elle télécharge (et met en cache) chaque logo de plugin trouvé...
    Je dirais… que… bah voilà… c’est pas un bug, c’est une feature :)
