Récupération d’informations sur le site maître à l’installation d’une instance

Utilité
Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

Can I convert a django video upload from a form using ffmpeg before storing the video ?

5 mai 2014, par GetItDone

I’ve been stuck for weeks trying to use ffmpeg to convert user uploaded videos to flv. I use heroku to host my website, and store my static and media files on amazon S3 with s3boto. The initial video file will upload fine, however when I retrieve the video and run a celery task (in the same view where the initial video file is uploaded), the new file won’t store on S3. I’ve been trying to get this to work for over a month, with no luck, and really no good resources available for learning how to do this, so I figure maybe if I can get the ffmpeg task to run before storing the video I may be able to get it to work. Unfortunately I’m still not a very advanced at python (or django), so I don’t even know if/how this is possible. Anyone have any ideas ? I am willing to use any solution at this point no matter how ugly, as long as it successfully takes video uploads and converts to flv using ffmpeg, with the resulting file being stored on S3. It doesn’t seem that my situation is very common, because no matter where I look, I cannot find a solution that explains what I should be trying to do. Therefore I will be very appreciative of any guidance. Thanks. My relevant code follows :

Unresolved symbols when linking ffmpeg 2.7.1 on OSX 10.10.4/amd64 with Xcode 6.4

9 juillet 2015, par Corey Brenner

I am seeing a problem linking against ffmpeg 2.7.1 (as installed by homebrew just today). Though the libraries in question are referenced on the command line, and though the linker admits to pulling in the correct libraries, and though the libraries themselves have the desired symbols (verified with NM), the symbols I need from the ffmpeg libraries do not show up.

My host and target platform is Mac x86_64, Xcode 6.4, OS X v10.10.4.

("ERROR (LINK.dll) : " is from my build system)

Thanks in advance !
