Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur
8 février 2011, parLa visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

Installation en mode ferme
4 février 2011, parLe 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 (...) -
Creating farms of unique websites
13 avril 2011, parMediaSPIP 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 convert messed-up .vtt sub file from youtube-dl —write-auto-sub download ?
27 septembre 2023, par perry_the_pythonMy goal is to download a YouTube video with auto-generated subtitles in a separate file like
.vtt,.srt, etc.

I am currently trying to achieve this with
youtube-dlbut I am open to other solutions if needed.

When I run the following command, it downloads the video as
.mp4(which is fine) and a separate.vttfile, but the.vttseems to be messed-up somehow and displays all the text for the whole clip at once instead of the specified times.

Command I am running :


youtube-dl --write-auto-sub https://www.youtube.com/watch?v=Roc89oOZOF4&list=PLJBo3iyb1U0eNNN4Dij3N-d0rCJpMyAKQ&index=45


Downloads this .vtt :

I have read that this may be done on purpose by YouTube.


Even if this is true, is there any way to convert this
.vttto a usable format or simply download correctly-formatted auto-generated subtitles from YouTube ?

Python, FFMPEG, cmd-line preferred, but anything is helpful !


Thanks ! Any and all assistance is greatly appreciated !

hwcontext_vulkan : correctly download and upload flipped images
21 avril 2020, par Lynnehwcontext_vulkan : correctly download and upload flipped images
We derive the destination buffer stride from the input stride,
which meant if the image was flipped with a negative stride,
we'd be FFALIGNING a negative number which ends up being huge,
thus making the Vulkan buffer allocation fail and the whole
image transfer fail.Only found out about this as OpenGL compositors can copy an entire
image with a single call if its flipped, rather than iterate over
each line.
