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 (...)

Adding text to the video without next converting
2 janvier 2020, par urbciechI have to add a short text at the beginning of the films 0:10 - 0:20. My client has a large database of 1M + movies. Currently, adding text to one movie is about 20 minutes, the reason is the conversion. Is it possible to do it faster without having to re-encode the movie ?. I came up with the idea to cut the beginning of each film 0:00 - 0:30 then add the text to this short excerpt and finally replace the beginning with a new piece of the film from with the text.
Is there any other way to speed up this process ?

Fetching movies' frames via ffmpeg and feed it to vlfeat's sift
16 novembre 2012, par KarlI am going to develop a program that uses ffmpeg and vlfeat on a linux server.
My task is simply : get some frames from a movie file and feed these frames to vlfeat's sift.
I am reading through some documents regarding using ffmpeg in c development, mainly here and here. As stated in the site, "There is not much "web based" official documentation for using these libraries." And some tutorials there might be a little outdated. I also read around that the API might differ from version to version. So I would like to ask for the following :
-
Is it safe to follow this tutorial for the current implementation ?
- If so, given the impression from above, what are some of the things that should be change for the current implementation ? (currently I got ffmpeg-git-c995644)
- If not, what are the functions to acquire the frames of the movie file in any format ?
-
For vlfeat side, if I am to feed a movie's image frame from ffmpeg, what kind of conversion is required so that vlfeat's sift implementation can "digest" the movie's image frame ?
