Script d’installation automatique de MediaSPIP

25 avril 2011, par kent1

Afin 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.

Que fait exactement ce script ?

18 janvier 2011, par kent1

Ce script est écrit en bash. Il est donc facilement utilisable sur n’importe quel serveur.
Il n’est compatible qu’avec une liste de distributions précises (voir Liste des distributions compatibles).
Installation de dépendances de MediaSPIP
Son rôle principal est d’installer l’ensemble des dépendances logicielles nécessaires coté serveur à savoir :

Automated installation script of MediaSPIP

25 avril 2011, par kent1

To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
The documentation of the use of this installation script is available here.

FFMPEG cannot encode .MP4 to usable .Y4M RAW video : "Operation not permitted"

26 janvier 2020, par Ham789

I am running ffmpeg version 4.2.2 on macOS Sierra and I cannot decode a RAW video.

First I create the .Y4M video :

ffmpeg -y -i inputfolder/GH012088.MP4 temp_raw_video.Y4M

Then I try to input it to ffmpeg :

ffmpeg -i temp_raw_video.Y4M

However I get the following error in the terminal : temp_raw_video.Y4M: Operation not permitted

I have checked the permissions for the ’temp_raw_video.Y4M’ file and I have both read and write permissions.

I have tried the above with .MOV videos from an iPhone and it works fine.

The problem seems to be with the .MP4 videos I am trying to convert. These videos were taken with a GoPro camera.

What is going on here ? Please see the GH012088.MP4 file info below :

Error opening video file with openCV cv2VideoCapture

7 juillet 2020, par kollo

I have a video file here /data/out.mp4 and its copy /data/out. 
I'm on Osx Sierra with Xcode 8.

Open video with mp4 extension is ok but get error with no extension or any other format.

I tryed opencv 2.4 and latest 3.2 from git.
Compiled with ffmpeg release/2.0 and also tryed release/3.0

With opencv version 3.2 :

Python 2.7.10 (default, Jul 30 2016, 19:40:32)&#xA;[GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.34)] on darwin&#xA;Type "help", "copyright", "credits" or "license" for more information.&#xA;>>> import cv2&#xA;>>> cv2.__version__&#xA;&#x27;3.2.0-dev&#x27;&#xA;>>> cv2.__file__&#xA;&#x27;/Users/johndoe/work/myproject/venv/local/lib/python2.7/site-packages/cv2.so&#x27;&#xA;

If video have extension :

If video have no extension :

My FFmpeg configure :

My opencv CMAKE :

cmake -D CMAKE_BUILD_TYPE=RELEASE \&#xA;-D CMAKE_INSTALL_PREFIX=/Users/johndoe/work/myproject/venv/local/ \&#xA;-D INSTALL_C_EXAMPLES=OFF \&#xA;-D PYTHON_PACKAGES_PATH=/Users/johndoe/work/myproject/venv/lib/python2.7/site-packages \&#xA;-D INSTALL_PYTHON_EXAMPLES=ON \&#xA;-D PYTHON_EXECUTABLE=/Users/johndoe/work/myproject/venv/bin/python \&#xA;-D WITH_CUDA=OFF ..&#xA;

I tryed various other formats reencoding my original video (ie : ffmpeg -i out.mp4 out.asf) :

>>> v=cv2.VideoCapture(&#x27;/data/out.avi&#x27;)&#xA;VIDEOIO(cvCreateFileCapture_AVFoundation (filename)): raised unknown C&#x2B;&#x2B; exception!&#xA;&#xA;>>> v=cv2.VideoCapture(&#x27;/data/out.flv&#x27;)&#xA;VIDEOIO(cvCreateFileCapture_AVFoundation (filename)): raised unknown C&#x2B;&#x2B; exception!&#xA;&#xA;>>> v=cv2.VideoCapture(&#x27;/data/out.asf&#x27;)&#xA;VIDEOIO(cvCreateFileCapture_AVFoundation (filename)): raised unknown C&#x2B;&#x2B; exception!&#xA;
