    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 (...)

    MédiaSPIP ne modifie jamais le document original mis en ligne.
    Pour chaque document mis en ligne il effectue deux opérations successives : la création d’une version supplémentaire qui peut être facilement consultée en ligne tout en laissant l’original téléchargeable dans le cas où le document original ne peut être lu dans un navigateur Internet ; la récupération des métadonnées du document original pour illustrer textuellement le fichier ;

  • Thread count option in FFmpeg for FASTEST conversion to h264 ?

    9 février, par S B

    I need to maximize speed while converting videos using FFmpeg to h264

    



      

    • Any input format of source videos

      • 


    • User's machine can have any number of cores

      • 


    • Power and memory consumption are non-issues

      • 


    



    Of course, there are a whole bunch of options that can be tweaked but this question is particularly about choosing the best -thread <count></count> option. I am trying to find an ideal thread count as a function of

    &#xA;&#xA;

      &#xA;
    • no. of cores

      • &#xA;

    • input video format

      • &#xA;

    • h264-friendly values maybe ?

      • &#xA;

    • anything else missed above ?

      • &#xA;

    &#xA;&#xA;

    I am aware the default -thread 0 follows one-thread-per-core approach which is supposed to be optimal. But I am not sure if this is time or space-optimized. Also, on certain testcases, I've seen more threads (say 4 threads on my dual core test machine) finishes quicker than the default.

    &#xA;&#xA;

    Any other direction, say configure options w.r.t. threads, worth pursuing ?

  • avformat/framehash : also print channel layout as a string

    avformat/framehash : also print channel layout as a string

    This should be more useful for users since numerical values for channel
    
layout can be confusing and unintuitive.
