18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

Install OpenCV3 for Python3 on Ubuntu 14.04
20 mai 2015, par AmorimI need to install OpenCV on Ubuntu 14.04 to work with Python3 but the only version that is compatible is OpenCV3 which is at 3.0 RC1 http://opencv.org/downloads.html
Following installation instructions I need to satisfy given dependencies :
- ...
- ffmpeg or libav development packages : libavcodec-dev, libavformat-dev, libswscale-dev
- [optionals] ...
However I can’t seem to be able to install neither ffmpeg or libav*. AFAIK ffmpeg doesn’t exist anymore (or isn’t recommended) for Ubuntu 14.04 so the best option is libav.
:~$ sudo apt-get update
:~$ sudo apt-get install libavcodec-dev
The following packages have unmet dependencies:
libavutil-dev : Depends: libavutil52 (= 6:9.18-0ubuntu0.14.04.1) but 7:1.2.6-1~trusty1 is to be installed
E: Unable to correct problems, you have held broken packages.System information
:~$ uname -a
Linux alande-Satellite-P755 3.13.0-53-generic #88-Ubuntu SMP Wed May 13 18:10:29 UTC 2015 x86_64 x86_64 x86_64 GNU/LinuxQ : Is there a neater (easier) way to install ffmpeg or libav* ? Or alternatively, a better way to install OpenCV3 on Ubuntu 14.04 (original problem) ?

How to convert video to Archos compatible format ? (details below)
19 mai 2015, par barrycarterEDIT : Rewriting completely to reflect what I’m actually trying to do.
Below are the results of "ffmpeg -i" on two files that I know my
Archos player will play properly.My question : what ffmpeg, vlc, mencoder, etc commands/options do I
need to convert an existing video to either one of the two formats
below ?In other words, how do I make non-Archos-compatible videos compatible
with Archos ?(note : Archos has confirmed they no longer even sell plugins to view
other types of videos, so transcoding is my only option)> ffmpeg -i Video\ 358\ -\ 24\ Jun\ 10,\ 00h00.AVI

[mpeg4 @ 0xa5deb80] Video uses a non-standard and wasteful way to store B-frames ('packed B-frames'). Consider using a tool like VirtualDub or avidemux to fix it.
