  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • Why does FFMPEG report the wrong duration ?

    27 avril 2013, par Adrian Lynch

    I have an oldish build of FFMPEG that I can't easily change.

    We use FFMPEG to find the duration of video and sound files. So far it has been working wonderfully.

    Recently on an uploaded file, FFMPEG has reported a 30 second file as being 5 minutes 30 seconds in length.

    Could it be something wrong with the file rather than FFMPEG ?

    If I use FFMPEG to convert to another file, the duration is restored.

    In case it matters, ffmpeg -i 'path to the file' produces :

        FFmpeg version Sherpya-r15618, Copyright (c) 2000-2008 Fabrice Bellard, et al.

    Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'H :\path\to\file.mov' :

        Stream #0.0(eng) : Audio : aac, 44100 Hz, stereo, s16
        Stream #0.1(eng) : Video : h264, yuv420p, 720x576, 25.00 tb(r)
    Must supply at least one output file

    It's that very command I use to then extract the duration with RegEx.

    Does anyone have a nice application that can do what I'm trying above but get it right 100% of the time ?

  • FFmpeg returning an error - What does it mean ?

    19 mars 2013, par user1031947

    I am using FFmpeg, libmp3lame & libx264 along with the node fluent-ffmpeg module. This is my first foray into processing uploaded videos.

    From node, I use the following code to process an uploaded video :

    var proc = new ffmpeg({ source: src, nolog: true })
    
    .usingPreset( "podcast" )
    
    .withAudioCodec( "libmp3lame" )
    
    .saveToFile( dest, function( retcode, err ){
    
         if( err ) throw err;
    
         ...
    
    });

    When I try to process a video, this fails with the following error, which I don't understand. I am hoping someone here can help point me in the right direction. Thanks !
