  • 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.

  • Ajouter des informations spécifiques aux utilisateurs et autres modifications de comportement liées aux auteurs

    12 avril 2011, par

    La manière la plus simple d’ajouter des informations aux auteurs est d’installer le plugin Inscription3. Il permet également de modifier certains comportements liés aux utilisateurs (référez-vous à sa documentation pour plus d’informations).
    Il est également possible d’ajouter des champs aux auteurs en installant les plugins champs extras 2 et Interface pour champs extras.

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • FFmpeg static keyframe rate

    7 novembre 2011, par 2di

    I have a question about ffmpeg usage. Every time when I trying to convert video files into
    some different format, output file getting static keyframe sequence.

    What I mean is that keyframes appear at the distance of 12 frames. I know that its controllerd by parameter -g that you can change to any other number.

    ffmpeg -i 1.avi -vcodec mpeg4 -b 2000000  out.avi

    I believe there should be some way to make keyframes appear on uneven intervals. These interval should be calculated by codec, and it should be based on image changes in the video file. So keyframes should be inserted only when they needed, but not consistently after N frames.

    Can somebody please explain to me how this "smart" encoding can be done with ffmpeg ?
    Thank you

    SOLUTION : ok what I'ev been looking for has very simple solution. If you set -g to zero, ffmpeg will choose keyframes based on the video shots and bitrate

  • Trying to determine h.264 profile & level pragmatically

    23 juin 2012, par kryptobs2000

    Ideally the solution would be in python and cross platform, but that's probably not too likely, so all I require is it work in linux, and I can use a c extension to interface w/python if necessary. I see there is a python binding for ffmpeg which I was thinking about using, however I can't figure out how to determine the profile and level as it is, with fmmpeg or anything else, much less do it pragmatically. Google is not much help on the matter either.

    I've been able to determine what features I'd be looking for if I needed to determine the profile and levels manually then I can do that, but then that leads to the question, can ffmpeg then determine if the video was encoded with that feature set ? I guess what I'm wondering to that effect is, is it perhaps not possible to fully determine the level and specific profile after encoding ? I would think you'd have to know in order to decode it, but maybe not ; that would explain why I can't find any information on it. I've been toying with this on and off for awhile, but recently decided to consider a project I'd been thinking about, but this is one of this big things holding me back.

  • Anomalie #2712 : Admin restreint sauvegarde la base ?

    17 mai 2012, par Julien -

    OK, ça ne se limitait donc pas aux admins restreints. Par contre, la question que je me posais était plus de savoir s’il y avait un réel usage du "pour tous" aujourd’hui. Car dans le cas contraire, certes c’est pas nocif mais c’est un élément d’interface qui ne sert à rien ou peut donner (...)
