  • 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 (...)

  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • HEVC : Fetching the input width and height from input bin stream

    1er juillet 2022, par Zax

    I have created an elementary bin stream using HM-12.0 reference code. So the out put is an HEVC encoded bin stream (say input.bin).

    



    I have a task which involves reading the header of this elementary stream. That is i need to fetch information such a the stream width, height etc. from the input.bin file.

    



    After seeing a lots of streams, i can conclude that all these bin streams starts from the sequence :

    



    00 00 00 01


    



    So whenever i see this sequence in any bin stream, i can say that this stream has to be decoded by HEVC decoder.

    



    Further if i want to fetch the width, height, fps etc. from the input.bin (like ff_raw_video_read_header function in ffmpeg), that are the steps need to be performed to fetch this information ?

    



    I have gone through the parsing section of the HEVC draft, but its very complicated for my level in video domain. Can anyone suggest a simple way to fetch the required information from the encoded bin file ?

    



    Any suggestions will be really helpful to me. Thanks in advance.
