  • 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.
    Version mono serveur
    La version mono serveur consiste à n’utiliser qu’une (...)

  • 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" (...)

  • How to use the —abr-ladder from x265 on ffmpeg

    14 septembre 2020, par Diego

    I'm trying to find out how to use the latest x265 abr-ladder option on ffmpeg, which promises up to 65% time savings compared to sequential generation, according to release notes, but : (1) I'm not sure if it is already available on ffmpeg or how to find out, and if it is (2) specifying the input/output inside the configuration file instead of the ffmpeg CLI causes ffmpeg to complain that required parameters are missing.

    &#xA;

    In the x265 repository there is a example for configuration file, but I couldn't find there or in the ffmpeg repository instructions on how to use this kind of parameter that doesn't seem to follow the CLI standards for ffmpeg. Apparently it is possible to create multiple outputs in a single command using ffmpeg, but again I couldn't make it work.

    &#xA;

    So what I'm looking for is a usage example for the --abr-ladder parameter for x265. Thank you.

  • Is ffmpeg support GPU acceleration on Jetson platform ?

    1er octobre 2020, par Vincent_Wang

    I want to run ZoneMinder on Jetson nano as an IP CAM server, but it seems that Jetson nano can not handle many cams which are using ffmpeg decode, if I open three cams on ZoneMinder, CPU usage is always 100%, but GPU usage is 0%, and I can not open more cams.

    &#xA;

    In this discussion https://forums.developer.nvidia.com/t/ffmpeg-using-hardware-gpu-cuda/72312, the NV Moderator said that

    &#xA;

    &#xA;

    ffmpeg with GPU support is not enabled on Jetson platform ...

    &#xA;

    &#xA;

    NVENC/NVDEC can help ffmpeg acceleration, but these hardware blocks is on CPU, not on GPU.

    &#xA;

    but I found a repo https://github.com/jocover/jetson-ffmpeg, is this repo can use GPU acceleration ? Because I tried but didn't work(still using NVENC/NVDEC acceleration of CPU).

    &#xA;

    If GPU on Jetson nano is sure that can not support ffmpeg acceleration, but I want to use ZoneMinder, is there a better way to solve this problem ? e.g. using GStreamer ?
