  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • 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 (...)

  • Android : Build a decoder library from Jpeg to MP4 video

    9 juillet 2014, par Ilya_Gazman

    I am working on Android 2.2, and my goal is to covert a sequence of images to mp4 video, MPEG-4_Part_14, to be more exact.

    The most reasonable solution would be using FFmpeg libraries, and compile them to Android using NDK. How ever I am looking for solution without NDK.

    I do not expect from you to build this tool for me, or find some one else who did. I spent quit of time now searching for that, and it’s some thing that probably no1 one did yet.

    So the only thing that I am asking, is help me find the specs so I be able to build the decoder by my self. I know that it’s not a trivial task(May be this is why no one did it yet), but I want to do it any way. So please just help me start it.

  • How to increase video encoding speed in ffmpeg ?

    16 octobre 2017, par Ashutosh Tiwari

    I am recording video clips and then joining all the clips in a final video.
    Everything goes fine but the joining process takes too long.

    Tried to using some ffmpeg filters from here :
    https://trac.ffmpeg.org/wiki/Encode/H.264

    And here is my ffmpeg command that I am using to increase the speed (which seems to be wrong) :

    command = new String[]{"-y",
    
                "-f",
    
                "concat",
    
                "-safe",
    
                "0",
    
                "-i",
    
                "/storage/emulated/0/DCIM/my_file.txt",
    
                "-c:v",
    
                "-preset",
    
                "fast",
    
                "-crf",
    
                "22",
    
                "copy",
    
                "-flags",
    
                "+global_header",
    
                "/storage/emulated/0/DCIM/SampleApp/" + videoOutputPath
    
        };

    Please help ! Thanks much.

  • WMA Lossless and ProRes Encoder

    4 mars 2012, par Multimedia Mike — General

    The projects (FFmpeg / Libav) just got a WMA lossless decoder. For those keeping score, this means that there are open source methods for decoding every single one of Microsoft’s proprietary audio codecs (Windows Media Audio, or WMA) : WMA v1, WMA v2, WMA9/Pro, WMA Voice, and now WMA lossless. Currently, it’s only advertised to decode 16-bit audio (no 24-bit). Also, when I first tried it a few days ago, it didn’t decode the very end of the single sample file I concocted many years ago (luckynight.wma). But that might be cleared up by now.

    Some other recent developments in the projects that I wanted to call out : An encoder for the Apple ProRes encoder from Kostya ; XWD (X window dump) image decoding and encoding from Paul B. Mahol ; a Sun rasterfile encoder from Aneesh Dogra.

    And then there’s the new playback system for CDXL files, also courtesy of Paul B. Mahol. I wasn’t familiar with this format until I wrote this post, which is surprising, given the format’s vintage. This was a CD-ROM FMV format favored for Amiga computers. Here it is in all its 160x120x10fps glory :



    That’s the amigaball.cdxl sample available in the repository. The sample is 3835910 bytes large and plays for about 24 seconds. This yields a data rate of about 159 kbytes/second. So, yeah, single-speed CD-ROM FMV.
