  • Le plugin : Gestion de la mutualisation

    2 mars 2010, par

    Le plugin de Gestion de mutualisation permet de gérer les différents canaux de mediaspip depuis un site maître. Il a pour but de fournir une solution pure SPIP afin de remplacer cette ancienne solution.
    Installation basique
    On installe les fichiers de SPIP sur le serveur.
    On ajoute ensuite le plugin "mutualisation" à la racine du site comme décrit ici.
    On customise le fichier mes_options.php central comme on le souhaite. Voilà pour l’exemple celui de la plateforme mediaspip.net :

  • Initialisation de MediaSPIP (préconfiguration)

    20 février 2010, par

    Lors de l’installation de MediaSPIP, celui-ci est préconfiguré pour les usages les plus fréquents.
    Cette préconfiguration est réalisée par un plugin activé par défaut et non désactivable appelé MediaSPIP Init.
    Ce plugin sert à préconfigurer de manière correcte chaque instance de MediaSPIP. Il doit donc être placé dans le dossier plugins-dist/ du site ou de la ferme pour être installé par défaut avant de pouvoir utiliser le site.
    Dans un premier temps il active ou désactive des options de SPIP qui ne le (...)

  • Data Privacy Day 2020

    27 janvier 2020, par Matthieu Aubry — Privacy

    It’s January 28th which means it’s Data Privacy Day !

    Today is an important day for the Matomo team as we reflect on our mission and our goals for 2020. This year I wanted to send a video message to all Matomo users, community members and customers. 

    Check it out (full transcript below)

    A video message from Matomo founder, Matthieu Aubry

    Privacy-friendly alternatives

    Video transcript

    Hey everyone,

    Matthieu here, Founder of Matomo.

    Today is one of the most significant days of the year for the Matomo team – it’s Data Privacy Day. And so I wanted to quickly reflect on our mission and the significance of this day. 

    In today’s busy online world where data is king, this day is an important reminder of being vigilant in protecting our personal information online.

    Matomo began 12 years ago as an open-source alternative to Google Analytics – the goal was, and still is to give full control of data back to users. 

    In 2020, we are determined to see through this commitment. We will keep building a powerful and ethical web analytics platform that focuses on privacy protection, data ownership, and provides value to all Matomo users and customers.

    And what’s fantastic is to see the rise of other quality software companies offering privacy-friendly alternatives for web browsers, search engines, file sharing, email providers, all with a similar mission. And with these products now widely available, we encourage you to take back control of all your online activities and begin this new decade with a resolution to stay safe online.

    I’ll provide you with some links below the video to check out these privacy-friendly alternatives. If you have a website and want to gain valuable insights on the visitors while owning your data, join us ! 

    Matomo Analytics On-Premise is and always will be free to download and install on your own servers and on your own terms.

    Also feel free to join our active community or spread the word to your friends and network about the importance of data privacy.

    Thank you all and wishing you a great 2020 !

  • Gstreamer channel reordering failed

    31 octobre 2017, par user972851

    I installed the library essentia which causes my previously working pipeline to crash :

    ** (gst-launch-1.0:22515): CRITICAL **: gst_audio_reorder_channels: assertion 'size % ((info->width * channels) / 8) == 0' failed
    
ERROR: from element /GstPipeline:pipeline0/GstRtpL16Depay:rtpl16depay0: Channel reordering failed.
    
Additional debug info:
    
gstrtpL16depay.c(276): gst_rtp_L16_depay_process (): /GstPipeline:pipeline0/GstRtpL16Depay:rtpl16depay0

    The pipeline looks like this :

    udpsrc port=5000 ! application/x-rtp,media=(string)audio,channels=1, clock-rate=(int)44100,encoding-name=(string)L16,payload=10 ! rtpL16depay ! audioconvert ! tee name=t ! queue ! autoaudiosink sync=false t. ! queue ! appsink name=codesink

    I am using gstreamer 1.0 on Ubuntu 16.04 and (re-)installed the libraries mentioned in the essentia doc :

    build-essential libyaml-dev libfftw3-dev libavcodec-dev libavformat-dev libavutil-dev libavresample-dev python-dev libsamplerate0-dev libtag1-dev
    
python-numpy-dev python-numpy python-yaml
    
ffmpeg

    The essentia install script finished ’successfully’ even though I cannot find MonoLoader or any other Audioloader.... (so still something wrong with essentia as well, but thats not the main problem !)

    Cleaned out parts of the gstreamer debug log look like this :
