  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • Why opencv3 requires libavcodec56 although opencv2 requires libavcodec57

    10 juin 2018, par TSR

    I have installed opencv using apt-get. I got opencv2 with the following version and it works fine :

    rover@rover_pi:/usr/lib/arm-linux-gnueabihf $ python2.7
    
Python 2.7.13 (default, Nov 24 2017, 17:33:09) 
    
[GCC 6.3.0 20170516] on linux2
    
Type "help", "copyright", "credits" or "license" for more information.
    
>>> import cv2
    
>>> cv2.__version__
    
'2.4.9.1'

    Then I wanted to install opencv on a conda environment using pip. I got the following version

    (olfatf)rover@rover_pi:/usr/lib/arm-linux-gnueabihf $ pip list | grep opencv
    
opencv-python          3.4.0.14  

    However, I get the following error when I import the module :

    (olfatf)rover@rover_pi:/usr/lib/arm-linux-gnueabihf $ python
    
Python 3.4.3 |Continuum Analytics, Inc.| (default, Aug 21 2015, 00:53:08) 
    
[GCC 4.6.3] on linux
    
Type "help", "copyright", "credits" or "license" for more information.
    
>>> import cv2
    
Traceback (most recent call last):
    
  File "<stdin>", line 1, in <module>
    
  File "/home/pi/.conda/envs/olfatf/lib/python3.4/site-packages/cv2/__init__.py", line 3, in <module>
    
    from .cv2 import *
    
ImportError: libavformat.so.56: cannot open shared object file: No such file or directory
    
</module></module></stdin>

    I checked the install libavcodec library and I get the version 57.

    (olfatf)rover@rover_pi:/usr/lib/arm-linux-gnueabihf $ ls | grep libavformat
    
libavformat.a
    
libavformat.so
    
libavformat.so.57
    
libavformat.so.57.56.101

    So I want to know why a later version of opencv requires an older version of libavcodec. Also, how can I installed both libavcodec56 and libavcodec57 on my machine ?

    I use a raspberry pi with Raspbian Strech

  • compat : remove in-tree NVidia headers

    26 février 2018, par Timo Rothenpieler
    compat : remove in-tree NVidia headers

    External headers are no longer welcome in the ffmpeg codebase because they
    
increase the maintenance burden. However, in the NVidia case the vanilla
    
headers need some modifications to be usable in ffmpeg therefore we still
    
provide them, but in a separate repository.
    

    The external headers can be found at
    
https://git.videolan.org/?p=ffmpeg/nv-codec-headers.git
    

    Fate-source is updated because of the deleted files, and dynlink_loader.h
    
license headers were updated with the standard FFmpeg headers.
