  • 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 (...)

  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • Encodage et transformation en formats lisibles sur Internet

    10 avril 2011

    MediaSPIP transforme et ré-encode les documents mis en ligne afin de les rendre lisibles sur Internet et automatiquement utilisables sans intervention du créateur de contenu.
    Les vidéos sont automatiquement encodées dans les formats supportés par HTML5 : MP4, Ogv et WebM. La version "MP4" est également utilisée pour le lecteur flash de secours nécessaire aux anciens navigateurs.
    Les documents audios sont également ré-encodés dans les deux formats utilisables par HTML5 :MP3 et Ogg. La version "MP3" (...)

  • Build FFMPEG with libx264 Android

    4 juin 2015, par Biraj Zalavadia

    I was able to Build FFMPEG with libx264 Android successfully and was working well before 2 months.

    I uses halfninja for building.

    Today I take latest source of ffmpeg and libX264 from here.

    git clone git://git.videolan.org/x264.git
    

    
git clone git://git.videolan.org/ffmpeg.git

    And try to rebuild whole project. But now it throws following errors.

     ffmpeg.c:2406: error: undefined reference to 'hwaccels'

  • Create a RTSP video stream on a .NET platform

    12 décembre 2012, par Goro

    I want to create a RTSP/h264 video stream from static images, and incorporate it into my .NET application. So far I have found two possible ways to do this :

    1. Use ffmpeg/ffserver, but I would need to compile ffserver on windows and then rely on it... and I don't necessarily want to rely on an external application

    2. Use the LIVE555 (http://www.live555.com) library, but they do not have any .NET libraries, so I would need to spend some effort to make it work with the rest of my .NET application.

    Can you comment on either #1, #2, or which is better. Is there a faster way to bring up a RTSP server in .NET ? I do not mind putting in development time if there is a solid solution that takes time, but it would be good to have something we can work with fast, for prototyping and demos.

    Thank you,

  • Fetching movies' frames via ffmpeg and feed it to vlfeat's sift

    16 novembre 2012, par Karl

    I am going to develop a program that uses ffmpeg and vlfeat on a linux server.

    My task is simply : get some frames from a movie file and feed these frames to vlfeat's sift.

    I am reading through some documents regarding using ffmpeg in c development, mainly here and here. As stated in the site, "There is not much "web based" official documentation for using these libraries." And some tutorials there might be a little outdated. I also read around that the API might differ from version to version. So I would like to ask for the following :

    1. Is it safe to follow this tutorial for the current implementation ?

      • If so, given the impression from above, what are some of the things that should be change for the current implementation ? (currently I got ffmpeg-git-c995644)
      • If not, what are the functions to acquire the frames of the movie file in any format ?

    2. For vlfeat side, if I am to feed a movie's image frame from ffmpeg, what kind of conversion is required so that vlfeat's sift implementation can "digest" the movie's image frame ?
