  • Emballe médias : à quoi cela sert ?

    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" ;

  • Gestion des droits de création et d’édition des objets

    8 février 2011, par

    Par défaut, beaucoup de fonctionnalités sont limitées aux administrateurs mais restent configurables indépendamment pour modifier leur statut minimal d’utilisation notamment : la rédaction de contenus sur le site modifiables dans la gestion des templates de formulaires ; l’ajout de notes aux articles ; l’ajout de légendes et d’annotations sur les images ;

  • 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 (...)

  • Unable to stream file onto localhost - ffmpeg

    18 octobre 2013, par trueblue

    I am new to ffmpeg/ffserver. I am trying to stream a local file named Trial onto a localhost using ffserver. I want to run the file in browser as http://localhost:8090/feed1.ffm
    I am executing the below command in Ubuntu(Trial is a Mpeg TS file) :

      ffmpeg -i Trial http://localhost:8090/feed1.ffm

    Upon execution of above command I am getting below error :

  • video overwriting using ffmpeg - I want to Add video rotation code and rewrite the existing file..How can i do that ?

  • FFMPEG enocde flv with alpha channel

    25 octobre 2013, par tree

    I'm trying to encode a video (mov) to an flv with alpha channel in FFMPEG but I can't seem to either

    1. find a codec that is supported
    2. find one that actually maintains the alpha

    Does anyone know how to set that up ?

    Thanks,

    ffmpeg -i abc_btr_1280x800_Takeover.mov -vcodec flv -pix_fmt yuv444p -s 1280x800 test4.flv

    here is the report...
