  • 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.

  • 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 (...)

  • Mixed Reality WebRTC without Signalling Server

    25 mai 2021, par SilverLife

    I am trying to find a way, which allows me to use Mixed Reality WebRTC (link to git-repo) without a signalling server.
In detail, I want to create a sdp-file from my ffmpeg Video sender and use this sdp-description in my unity-Project to bypass the signaling process and receive the ffmpeg video stream.
Is there a way of doing so with Mixed Reality WebRTC ? I was already searching for the line of code, where the sdp-file is created within MR WebRTC but I didn´t find it.

    


    I am relatively new to this topic and I am not sure if this works at all but since ffmpeg is not directly compatible with webrtc I was thinking that this might be the most promising approach.

    


  • Subtitles in ffmpeg/libavfilter

    15 juin 2021, par Captain Jack

    I have a C program to read video/audio with libav/ffmpeg libraries and decode it.

    



    I am playing with some filters and most work just fine. I can draw text, overlay logos, flip and invert video colours. However, I am having big issues overlaying subtitles.

    



    My filter is very simple.

    



    const char *vfilter_descr = "[in]subtitles=subs.srt[out]";


    



    On the console I get this :

    



    [Parsed_subtitles_0 @ 0x7fe76c703240] Shaper: FriBidi 0.19.7 (SIMPLE) HarfBuzz-ng 2.4.0 (COMPLEX)
[Parsed_subtitles_0 @ 0x7fe76c703240] Using font provider coretext
[Parsed_subtitles_0 @ 0x7fe76c703240] fontselect: (Arial, 400, 0) -> /Library/Fonts/Microsoft/Arial.ttf, -1, ArialMT
[Parsed_subtitles_0 @ 0x7fe76c703240] fontselect: (Arial, 400, 100) -> /Library/Fonts/Microsoft/Arial Italic.ttf, -1, Arial-ItalicMT


    



    ...which somewhat confirms that subtitles are loading, though I am not sure why there are two fonts being loaded ?

    



    However, they are not showing at all - almost as if they never loaded. I tried several different files, including ASS ones but no luck.

    



    ffmpeg version is the latest one.
