    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • Scroll one image top to bottom

    17 septembre 2018, par Cyber

    I am trying to scroll an image top to bottom like this video :
    https://youtu.be/8GCrrsiBLzs

    And here’s what I tried

    ffmpeg -loop 1 -t 24 -i "image.jpg" -filter_complex "color=000000:s=640x360[bg]; [bg][0]overlay=shortest=1:y='min(0,-(t)*26)'" -y out6.mp4

    But video didn’t created, ffmpeg close immediately and returns following results :

  • ffmpeg Too many bits per frame requested

    18 novembre 2016, par GRaecuS

    I am using ffmpeg to convert videos to mp4 format. Everything works fine except with MOV format.

    The command I use for everything is :

    ffmpeg -i input.mov -strict experimental -sameq -s vga -aspect 1.7777 -vcodec libx264 -preset fast -crf 22 -y output.mp4

    but the output I keep getting is :

Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height

    It seems the problem is with audio’s bit per frame.
    Which might be the right solution ?

  • FFMPEG Error while opening decoder for input stream

    6 mars 2016, par Chris

    While this command his been working for a couple of months, I suddenly began running into the following error when encoding video via my php application. Testing the encoding parameters on the command line yielded the same results, while the verion of ffmpeg on my local machine has no problem reading the input

    Command I used :

    ffmpeg -i clip_20121022150813.mp4 -acodec libfaac -ab 44100 encoded.mp4

    And the output (error on last line) :

    I have uninstalled ffmpeg, recompiled from source, also recompiled x264 and a host of other libraries, but this error persists. Is there anyway I can find out more about what exactly is failing ?
