  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • 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.

  • Le plugin : Gestion de la mutualisation

    2 mars 2010, par

    Le plugin de Gestion de mutualisation permet de gérer les différents canaux de mediaspip depuis un site maître. Il a pour but de fournir une solution pure SPIP afin de remplacer cette ancienne solution.
    Installation basique
    On installe les fichiers de SPIP sur le serveur.
    On ajoute ensuite le plugin "mutualisation" à la racine du site comme décrit ici.
    On customise le fichier mes_options.php central comme on le souhaite. Voilà pour l’exemple celui de la plateforme mediaspip.net :

  • Resize the video

    8 juin 2016, par Android dev

    I have a requirement for video size before upload on the server and would like to resize the video to make sure it will not go the threshold.

    So far I ended up with this command :

    ffmpeg -y -i E:\test3.mp4 -s 640*480 -r 15 -aspect 3:4 -ab 12288 -vcodec mpeg4 -b 2097152 E:\debug_video.mp4

    The issues with this command :
    - is it changes aspect ratio of the video
    - it works too slow (30 seconds for 12 seconds 24mb video on Nexus 5)

    The best solution so far for the first issue is to check the video resolution first and only than run the ffmpeg.

    Do you know how to do that with help of ffmpeg as two separate commands or as a single one ? Do you know how to make it faster ? Thank you in advance

    UPDATE
    The console output is below. Please let me know if you would like to get console output for onProgress callback

  • Ffmpeg avs to avi lossless conversion

    21 février 2016, par Piotr

    How to convert avs (Avisynth file) to avi without loss of quality ?

    Firstly, I’m changing avs to 264 :

    ffmpeg -i "Source.avs" -c:v libx264 -preset veryslow -crf 24 "Output.264"

    Secondly, I’m trying to convert 264 to avi :

    ffmpeg -i "input.264" "output.avi"

    Final avi should have almost 200MB, but has only 2MB. 264 file has almost 150MB, so it should be good. I think that I should use some codec in second command, but I don’t know which. I’m trying to change this for a few days, but without effect.

    Or maybe there is a way to lossless conversion without 264, only avs to avi ?

    Thank you for your help.

    Edit :

    Thank you for answers. Unfortunatelly, both methods fail.
    First gives me a video, which is blurry and I can’t see anything on it.

  • RTSP relay using ffmpeg library

    23 novembre 2015, par kiran_g

    I am implementing an RTSP relay using libavcodec (ffmpeg). Basically, it connects to an IP camera, which is an RTSP server, PULLs the stream and then PUSHes it to wowza. I am finding it very difficult to get any sample implementation for this in the internet. So I started implementing this using bits and pieces from here and there. I took code for code samples to a) read RTSP stream and write to file b)read from file and serve it over RTSP.

    This is the current state of the code :

    When we run this we are getting this error :

    But I could see that the correct pixel format macro "AV_PIX_FMT_YUV420P" is provided.

    UPDATE 1 :
    This is the section in ffmpeg where the error is thrown from(utils.c line 1547) :

    if (avctx->codec->pix_fmts) {
               for (i = 0; avctx->codec->pix_fmts[i] != AV_PIX_FMT_NONE; i++)

                   char buf[128];
                   snprintf(buf, sizeof(buf), "%d", avctx->pix_fmt);

                   ret = AVERROR(EINVAL);
                   goto free_and_end;
               }

    Can someone suggest a solution for this.

    Thanks
