  • 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 (...)

  • Encoding and processing into web-friendly formats

    13 avril 2011, par

    MediaSPIP automatically converts uploaded files to internet-compatible formats.
    Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
    Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
    Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
    All uploaded files are stored online in their original format, so you can (...)

  • imageresizing.net : remote, extensionless files

    21 janvier 2015, par cwnchckn

    I am trying to set up a thumbnailing service supporting the most common image formats as well as PDF and some video formats. The storage backend is a simple HTTP server. The files, however, are stored using synthetic names equal to their crytographic hash and do not have extensions.

    I have a working system running ImageResizer as a HttpModule, loading the files using RemoteReader. It is set up to skip file type checks. However, I need to find a way to specify the exact decoder to use (such as with WIC, that supports &decode=wic in the request arguments), for instance &decoder=pdf or &decoder=ffmpeg. I suppose parsing the request arguments in PostAuthorizeRequestStart and extracting the decoder parameter value would be a good place to start, but I have no idea what to do next, as this is my first time ever touching Microsoft tech and the ASP.NET app anatomy is not immediately obvious.

    I would appreciate any hints, thanks

    6 février 2020, par user8606643

    initially, pip install av asked me to download visual C++ 14 build tools which I did
    but it is still showing me LINK 1181 errors

    I need this pyAV pakcage which is obtained by pip install av for a project, but it always shows some kind of error linked with C++ and i also have ffmpeg installed.
