    4 février 2011, par

    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" ;

  • Déploiements possibles

    31 janvier 2010, par

    Deux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
    L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

  • php ming flash swf slideshow to mp4/avi

    19 août 2013, par Stefan

    After hours of searching and trying i finally got a nice script together that generates a good looking Flash .swf file with a nice transaction in between de images.
    It works great if you access the swf file directly in a browser, depending on the amount of images the flash created takes anywhere between 10 and 60 seconds.
    But when uploading to Youtube the movie created flashed by in one second.
    Because swf isnt really a accepted fileformat for Youtube we decided to convert the flash file to mp4 or avi using ffmpeg.
    Unfortunally that didnt work, it had the same effect as the youtube movie.
    We had a old version of ffmpeg and updated that to a recent version and tried to convert again with the same result.
    The main thing i see is that ffmpeg cant see the swf file duration and bitrate, they are both 'N/A' while were do set them in the php script.
    I thought it looked like the Metadata doesnt get written and i cant find anything on that regarding Ming.
    But i downloaded a phpclass that extracts the metadata from the swf and that tells me the framerate etc is getting set.

    Now i have to admit i havent really tested with the new version because the commandline options are a little different but ill work on that after i post this.
    In the previous version we tried setting the framerate of the source swf file, but that didnt work either.

    Anyone here that can has a idea ? it would be greatly appriciated.

    PHP Ming Script :

    How do i compile the sample programs given in FFMPEG. i am not able to compile as i get
    error as CODEC_TYPE_VIDEO undeclared. Can any one please suggest me how to compile the programs. I am using ubuntu 11.

    This is the first example :

    $ gcc -o tutorial01 tutorial01.c -lavutil -lavformat -lavcodec -lz

    This is the output I got :
