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.

why I can't compile x264 or ffmpeg downloaded from git [closed]
4 avril 2013, par Monjura RumiIt has been just a few days that I am using x264, ffmpeg and trying to take help from codes in git. I am always having some peculiar problem. It seems like no one or few people faced such problems. Here is one of those problems. If I download x264 or ffmpeg using git then I could not compile that source code. At first terminal will show
./configure: Permission denied
. Then If I change permission of configure file usingchmod 755
command then it will show./configure: /bin/bash^M: bad interpreter: No such file or directory
. To build x264 and ffmpeg I have followed this link https://github.com/lince/libffmpeg-c/wiki. My attempt to compile x264 has failed. Can you please tell me how can one use source code downloaded from git ? -
ffmpeg thumbnails : Every 2 seconds, generated at 0, 1, 3, 5 seconds
30 janvier 2014, par Jim MillerI'm using ffmpeg to generate thumbnails from a piece of .mov video. I want to get thumbnails every two seconds, and so, copying almost directly from https://trac.ffmpeg.org/wiki/Create%20a%20thumbnail%20image%20every%20X%20seconds%20of%20the%20video, I'm doing :
ffmpeg -i test.mov -f image2 -vf fps=fps=1/2 thumb%04d.jpg
This works, and gives me thumbnails, but they correspond to the images from the video at 0, 1, 3, 5, ... seconds. I was expecting 0, 2, 4, 6, ... seconds ; I'm not sure why there's an initial one second gap between thumbnails before it settles into making them every two seconds.
Is there a way to get them to come out at 0, 2, 4, 6... seconds, or is this just "how it works" ? Thanks !

How to extract image frames from a bagfile ?
12 mars 2014, par LeyonceI am using ROS hydro on Ubuntu 12.04. After using the command "rosrun image_view extract_images _sec_per_frame :=0.01 image :=IMAGE_TOPIC_IN_BAGFILE" I'm having an error when executing"ffmpeg -r -b -i frame%04d.jpg .avi" The thing is I am not seeing the sequence of images after I play the bagfile.I ran "rosbag info" to obtain the topic in the bag file but when I run "rosrun rqtgraph rqtgraph" the /extract_image frame node is there all by itself.
When I follow the tutorials on http://wiki.ros.org/rosbag/Tutorials/... I get an error " [FATAL] [1394583654.335465840] : Error opening file : play".After replacing play by "--clock" everything seemed to go just fine but there are no frames*.jpg in /home/.ros hence the sequence of images are still missing. I feel like I'm lacking something.Can anyone help ?
