Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

Ajouter des informations spécifiques aux utilisateurs et autres modifications de comportement liées aux auteurs
12 avril 2011, parLa manière la plus simple d’ajouter des informations aux auteurs est d’installer le plugin Inscription3. Il permet également de modifier certains comportements liés aux utilisateurs (référez-vous à sa documentation pour plus d’informations).
Il est également possible d’ajouter des champs aux auteurs en installant les plugins champs extras 2 et Interface pour champs extras. -
La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

Transcoding video using ffmpeg from the internet or over http
19 juillet 2015, par RobinI have a project for transcoding videos. Right now I am passing the absolute path of the video as the input variable, as such :
inputfile = str(MEDIA_ROOT)+'/'+str(video.original_video)
Here the MEDIA_ROOT is /home/user/code/Project/Viu/static/media
And then
subprocess.call(
'ffmpeg -i '+ inputfile +' -codec:v libx264 -crf 23 -preset faster -codec:a libfdk_aac -vbr 4 \-movflags faststart -vf scale="720:trunc(ow/a/2)*2",format=yuv420p '+ outputfile,
shell=True
)This is ok for now. But I will be keeping those videos on different location from the server, how can I convert videos from that location over the internet or http?
I tried this :
inputfile = 'http://localhost:8000/media/'+str(video.original_video)
But I get this error :

Node.js ffmetadata incorrect codec parameters
21 juillet 2015, par Ahmed HamdyI’m making a song downloader app in Node.js. I managed to get everything to work, the app downloads the song and downloads its artwork (image). So I have the mp3 file and jpg file. The only problem is attaching the jpg file to the mp3 file.
I’m using the ffmetadata node.js module. I downloaded and installed its dependency "ffmpeg" cli.
Now when I try to write the metadata to the mp3 file and attach the artwork it spits this error :
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument
My code :
ffmetadata.write('test.mp3', {}, {attachments: ['test.jpg']}, function(err) {
if (err) console.error(err);
});The error :
