  • Other interesting software

    13 avril 2011, par

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • Déploiements possibles

    31 janvier 2010, par

    Deux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
    L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

  • Configuration spécifique d’Apache

    4 février 2011, par

    Modules spécifiques
    Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
    Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

  • Weird and unpredictable crash when using libx264 cross-compiled with MinGW

    2 mars 2012, par Daniel

    I'm working on a C++ project using Visual Studio 2010 on Windows. I'm linking dynamically against x264 which I built myself as a shared library using MinGW following the guide at

    http://www.ayobamiadewole.com/Blog/Others/x264compilation.aspx

    The strange thing is that my x264 code is working perfectly sometimes. Then when I change some line of code (or even change the comments in the file !) and recompile everything crashes on the line

    encoder_ = x264_encoder_open(&param);

    With the message

    Access violation reading location 0x00000000

    I'm not doing anything funky at all so it's probably not my code that is wrong but I guess there is something going wrong with the linking or maybe something is wrong with how I compiled x264.

    The full initialization code :

    x264_param_t param = { 0 };
    if (x264_param_default_preset(&param, "ultrafast", "zerolatency") < 0) {
     throw KStreamerException("x264_param_default_preset failed");
    }

    param.i_threads = 1;
    param.i_width = 640;
    param.i_height = 480;
    param.i_fps_num = 10;
    param.i_fps_den = 1;

    encoder_ = x264_encoder_open(&param); // <-----
    if (encoder_ == 0) {
     throw KStreamerException("x264_encoder_open failed");
    }

    x264_picture_alloc(&pic_, X264_CSP_I420, 640, 480);

    Edit : It turns out that it always works in Release mode and when using superfast instead of ultrafast it also works in Debug mode 100%. Could it be that the ultrafast mode is doing some crazy optimizations that the debugger doesn't like ?

  • FFMPEG : could not run filter error

    3 octobre 2013, par Vigo

    I have static builds for FFMPEG. I run a video streaming command from the console. I get a 'could not run filter error'.

    enter image description here

    What are the generic causes of this error ? Is it an issue with the parameters passed or is it something to do with the video capturing device (in my case, Webcam) itself ? Could anyone throw some light on this ?

  • Linphone OSx msx264 encryption VGA takes 97% CPU, why ?

    11 septembre 2013, par Maxim Shoustin

    I have problem and today don't know how to fix it or even from where to start.

    I have Linphone application that uses msx264 plugin.

    All stuff I run on OSx and my ffmpeg version installed from port , I didn't using selfupdate for port

    bash-3.2# port installed ffmpeg-devel

    The following ports are currently installed:
    ffmpeg-devel @20130205_0+gpl2
    ffmpeg-devel @20130328_0 (active)
    ffmpeg-devel @20130328_0+gpl2

    So I compiled and build msx264, no errors.

    Now I try to send video over CIP resolution VGA (640x480) and get huge delay 8-9 seconds, even self-view I see in big delay.

    when I configure CIF (352x288), all seems fine.

    It's really strange that self-view camera has delay 4-5 sec.

    So from logs during the session I found that msx264 plugin takes 97% CPU

    On PC (windows 7) the same code runs fine, even HD I don't see any problems.

    What is the problem should be ?
