  • 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 (...)

  • How to "extend" aws docker base image (.net core from scratch) by ... libs/ubuntu/ffmpeg ?

    26 avril 2022, par Nigrimmist

    i would like to use AWS Lambda through the image containers using .net core 3.1 and it is works fine for me in simplest code case. But i stucked with next scenario :

    


    By default, aws provide base image with .net core with aws libs based on "from scratch". So as i know, it minimal Linux that does not contains even package manager.

    


    I need to work with ffmpeg in the code, but to do it i need to install few packages and ... fmpeg. I have working code on image

    


    FROM mcr.microsoft.com/dotnet/runtime:3.1-bionic


    


    It is ubuntu with .net core runtime. But what is the right strategic in case of AWS Lambda image ? How can i ... merge them ?.

    


    Have few ideas, but not sure :

    


      

    1. use as is FROM public.ecr.aws/lambda/dotnet:core3.1 and try to install package manager, all depenendencies to use ffmpeg and so on ?

      2. 


    2. Use mcr.microsoft.com/dotnet/runtime:3.1-bionic, somehow add required by amazon dependencies (how ? download content and attach from local ?) and configure it to run in Lambda runtime ?

      3. 


    3. ... ?

      4. 


    


    Will be glad to hear where is the solution here. Thanks !

    


  • Building ffmpeg on mac results in undefined symbols

    9 juin 2017, par Peter

    Environment : macOS 10.12.5, Xcode 8.3.3, pkg-config installed via brew

    I need to build a minimal version of ffmpeg that supports H.264 decoding. I have downloaded the source for ffmpeg version 3.3.1 and have successfully built it for Windows and Linux. Now, I am trying to build it for mac.

    The specific flags of the configuration that are relevant are :

    --disable-yasm
    
--disable-everything
    
--enable-decoder=h264
    
--enable-decoder=h264_vda
    
--enable-vda

    After running the configuration, when I run make, all the libraries such as libavcodec.a, libavfilter.a, libavformat.a, are built. However, ffmpeg itself does not get built. The error I get is :

    Undefined symbols for architecture x86_64:
    
  "_ff_vda_create_decoder", referenced from:
    
      _vdadec_init in libavcodec.a(vda_h264_dec.o)
    
  "_ff_vda_destroy_decoder", referenced from:
    
      _vdadec_init in libavcodec.a(vda_h264_dec.o)
    
      _vdadec_close in libavcodec.a(vda_h264_dec.o)
    
ld: symbol(s) not found for architecture x86_64

    Looks like the functions are defined in ./libavcodec/vda_h264.c. However, it appears vda_h264.c is never compiled. Other vda related files such as vda.c and vda_h264_dec.c do get compiled (and added to libavcodec.a).

    I am thinking perhaps I am missing a configuration flag. Can someone please help ? Regards.
