  • La file d’attente de SPIPmotion

    28 novembre 2010, par

    Une file d’attente stockée dans la base de donnée
    Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
    Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...)

  • 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 (...)

  • Force x264 to encode all frames relative to the first (IDR) frame

    12 décembre 2019, par cloudraven

    I want to generate a h.264 stream in which P-frames are using references exclusively using a long-term reference to the first frame (an IDR frame). This would also require the first frame to be an IDR frame.

    



    This is an academic experiment to understand the encoding behavior of long-term references and the consequences of forcing frames to refer to a specific (single) frame rather than several.

    



    It would be great if I could do this from the command line, but if not possible I am open to modifying x264 for this purpose.

    



    Could anyone point me to where in the source code it is determined :

    



      

    • the reference frame / macroblock / partition for the current macroblock

      • 


    • changes made to the short term, long term reference frame list

      • 


    • whether to use a short term reference frame or a long term reference frame.

      • 


    



    Using another encoder like nvenc is also acceptable.
