28 novembre 2010, parUne file d’attente stockée dans la base de donnée

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 (...) -
Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

How to open and view an image stored in .yuv format ?
20 juin 2018, par ElectrixI have an image(grayscale) stored as a .yuv file. How do i open the image to see with any viewer or preferably opencv ??
Using on command line -
display -size 640x480 -colorspace gray -depth 8 4:2:0 -interlace plane 0001.yuvshows the image in a blurred form.
ffmpeg -i 0001.bmp.yuv -f rawvideo -pix_fmt gray out.jpggives -Output file #0 does not contain any stream
Its a 640x480 image. All the related questions talk about .yuv videos.

Download a video from blob:https url from eventive
26 août 2020, par jjcasmarI want to download a video from eventive but the tag contains a blob url (blob :https://watch.eventive.org/**************).


I have been reading some answers to similar questions but they all assume that the video has a mp3u8 file extension, which in my case doesn't.


I have also tried to directly download that url (removing the blob :) with curl, but I obtained a html code which I cant really understand, which contains a lot of references to javascript files.


Any tip would be really helpful.


Edit :


I have been doing some more tests and I have been able to found a url to a manifest file which points apparently to the video data. I have tried to open that url using VLC and it loads some info about the video, and it even plays it, but the screen is completely black.


I have also tried to download it using ffmpeg but it gives a bunch of errors.


ffmpeg -i https://eventiveprod-usea.streaming.media.azure.net/02968382-069a-4f02-ab3b-67c0b5a8d5b7/5f427f2d65a569006ebd326c.ism/manifest\(format\=mpd-time-csf\) output.mp4
