Amélioration de la version de base
13 septembre 2013Jolie 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 (...) -
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" ; -
Le plugin : Gestion de la mutualisation
2 mars 2010, parLe plugin de Gestion de mutualisation permet de gérer les différents canaux de mediaspip depuis un site maître. Il a pour but de fournir une solution pure SPIP afin de remplacer cette ancienne solution.
Installation basique
On installe les fichiers de SPIP sur le serveur.
On ajoute ensuite le plugin "mutualisation" à la racine du site comme décrit ici.
On customise le fichier mes_options.php central comme on le souhaite. Voilà pour l’exemple celui de la plateforme mediaspip.net :

run ffmpeg commands from my own project
28 octobre 2013, par brunoI'm starting a project where I want ppl to upload videos of a talk and a the video of slides for that talk and want to merge them (to play at the same time) and then show results.
My question is :
Is it possible to do that from code ? if it is, can you point me to the right doc ?
I was able to do it running command line, but as I want this to run on a server with different ppl uploading their videos I think this would not be the best approach.
I have a preference for Java if it's possible to do it, but I can manage to use other languages what do you guys suggest ?The idea would be to have a service where I can point the urls of the videos stored in my server and it would merge them and save file where I can later stream. With different ppl uploading videos at the same time and being able to watch the result in a reasonable amount of time.
I used this tutorial to test :

mov : Export geotag metadata fields
3 juin 2014, par Martin Storsjömov : Export geotag metadata fields
The ’ ?xyz’ form is used by android devices (and according to apple
mailing list archives, also by older iOS devices). The ’loci’ field
(defined in 3GPP 26.244) is used by recent iOS devices.Even though the loci field can contain an altitude, it was plain
0 in my sample. Just export longitude and latitude, in a string
format matching the one used by the ’ ?xyz’ metadata field.Signed-off-by : Martin Storsjö <martin@martin.st>

FFmpeg conversion to mp3 works in terminal, not in script
19 juillet 2013, par user2598172I can run
ffmpeg -i test.m4a -vn -acodec libmp3lame -ab 256k test.mp3
And it works perfectly. However, when I have the line :
./ffmpeg -i "$SONG_SAVE.m4a" -vn -acodec libmp3lame -ab 256k "$SONG_SAVE$EXT" &> /dev/null
running in a .sh script (downloading the same file that I was able to successfully convert through the terminal), it returns an mp3 file with no audio data. Does anyone have any idea what could be causing this ? Thanks !
