Il fournit également une page supplémentaire qui n’apparait que lorsque certains plugins sont activés permettant de contrôler l’affichage et les fonctionnalités spécifiques (...) -
Emballe médias : à quoi cela sert ?
4 février 2011, parCe plugin vise à gérer des sites de mise en ligne de documents de tous types.
Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ; -
Use, discuss, criticize
13 avril 2011, parTalk to people directly involved in MediaSPIP’s development, or to people around you who could use MediaSPIP to share, enhance or develop their creative projects.
The bigger the community, the more MediaSPIP’s potential will be explored and the faster the software will evolve.

Anomalie #4074 (Nouveau) : Le code de plugin-dist/medias/modeles/video.html , produit un paragraph...
11 janvier 2018, par eldk -Le code de plugin-dist/medias/modeles/video.html , produit un paragraphe de trop et casse le html.

Ffmpeg encoding too slow
8 mars 2024, par Marc CuadrasI'm using a Python script to encode mp4 videos in various qualities, in my case 360 +720 +1080.
Ffmpeg encoding videos very slow, 1 video taking 2 hours or more, I'm using good dedicated server from hetzner (ryzen 5 3600 + 64gm ram), any suggestion to improve speed will be really appreciated

avformat/segafilmenc : Postpone check for existence of video stream
14 janvier 2020, par Andreas Rheinhardtavformat/segafilmenc : Postpone check for existence of video stream
Up until now, the Sega FILM muxer complained if the first stream wasn't a
video stream that there is no video stream at all which is of course
nonsense. So postpone this check.Signed-off-by : Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
