    This page lists some websites based on MediaSPIP.

  • Amélioration de la version de base

    Jolie sélection multiple
    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • 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" (...)

  • lavc/qtrle : Do not use aligned writes for 24bit frames.

    lavc/qtrle : Do not use aligned writes for 24bit frames.

    pixel_ptr is 3 and leads to aligned access on odd memory addresses.
    
Fixes crashes on systems that do not allow unaligned access like sparc32.

  • Use ffmpeg static and not binaries for Discord Bot

    25 novembre 2019, par Ellis Thompson

    I am running a CentOS Linux server. I am trying to get ffmpeg to work on my discord bot. I have followed the guides using npm and switched npm i ffmpeg-binaries for npm i ffmpeg-static but it is still telling me that ffmpeg cannot be found.

    Most of the answers I’ve looked at either resolve around using sudo, which is not an option here, or they are for windows based systems.

  • How can I quantitatively measure gstreamer H264 latency between source and display ?

    16 décembre 2014, par KevinM

    I have a project where we are using gstreamer , x264, etc, to multicast a video stream over a local network to multiple receivers (dedicated computers attached to monitors). We’re using gstreamer on both the video source (camera) systems and the display monitors.

    We’re using RTP, payload 96, and libx264 to encode the video stream (no audio).

    But now I need to quantify the latency between (as close as possible to) frame acquisition and display.

    Does anyone have suggestions that use the existing software ?

    Ideally I’d like to be able to run the testing software for a few hours to generate enough statistics to quantify the system. Meaning that I can’t do one-off tests like point the source camera at the receiving display monitor displaying a high resolution and manually calculate the difference...

    I do realise that using a pure software-only solution, I will not be able to quantify the video acquisition delay (i.e. CCD to framebuffer).

    I can arrange that the system clocks on the source and display systems are synchronised to a high accuracy (using PTP), so I will be able to trust the system clocks (else I will use some software to track the difference between the system clocks and remove this from the test results).

    In case it helps, the project applications are written in C++, so I can use C event callbacks, if they’re available, to consider embedding system time in a custom header (e.g. frame xyz, encoded at time TTT - and use the same information on the receiver to calculate a difference).
