  • 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" (...)

  • Evolution #4573 (Nouveau) : Enlever Jquery UI du Core

    13 octobre 2020

    Jquery UI (https://jqueryui.com/) n’a plus d’activité maintenue (en tout cas aucune release depuis 4 ans maintenant).

    Il serait opportun de supprimer jQuery_UI du core, et de le remplacer par des librairies spécifiques pour les besoins identifiés.

    Tout d’abord l’usage dans le Core.

    Je crois que l’on utilise :

    le dateur

    À remplacer par https://duetds.github.io/date-picker/ ?
    Voir également la discussion sur Saisies : https://git.spip.net/spip-contrib-extensions/saisies/issues/43

    le sortable

    À remplacer par https://sortablejs.github.io/sortablejs/ ?

    D’autres plugins s’appuient sur d’autres éléments le jQuery-UI :

    - Accordéons et Tabs (Fabrique)
    - Une extension picker multidate (Agenda)
    - ...

    Dans un premier temps, il « suffit » qu’ils mettent le plugin jQueryUi actuel en dépendance...
    Dans un second temps... trouver des alternatives adaptées... et faire en sorte qu’elles soient partageables entre différents plugins si besoin.

    Sur le partageables

    Il pourrait y avoir un plugin du core regroupant des librairies js utilisées régulièrement, comme le faisait le plugin jquery-ui, mais avec différentes librairies plus indépendantes.
    Pourquoi pas. Plutôt que de faire N petits plugins JS.

  • Saving Raw Uncompressed Video Files using OpenCv, Gstreamer, and/or FFMPEG ?

    20 septembre 2022, par adav0033

    I have been trying to implement the cv::VideoWriter function from OpenCV to generate a an uncompressed (raw) video file. I started this because of a statement within the OpenCV Documentation which I will link here along with the statement.

    


    cv::VideoWriter::VideoWriter    (   const String &  filename,
int     fourcc,
double  fps,
Size    frameSize,
bool    isColor = true 
)       


    


    "If FFMPEG is enabled, using codec=0 ; fps=0 ; you can create an uncompressed (raw) video file."

    


    Ref. https://docs.opencv.org/3.4/dd/d9e/classcv_1_1VideoWriter.html

    


    However whilst troubleshooting the function I came across the refuting statement,

    


    " VideoCapture and VideoWriter do not provide interface to access raw compressed video stream, except maybe MJPEG in some cases.
Make sure you actually use FFmpeg backend by setting apiPreference parameter : VideoWriter("outfile.avi", cv2.CAP_FFMPEG, ...)"

    


    Ref. https://github.com/opencv/opencv/issues/14573

    


    I am now confused about how I go about writing the cv::VideoWriter function to satisfy the requirements to create a raw uncompressed video file (.avi) and if it is even possible. If it is not possible how do I achieve the outcome of saving an raw uncompressed video file, as I assume it would use some combination of FFMPEG, OpenCV,or Gstreamer.

    


    Note : My code is implemented in c++
