MediaSPIP en mode privé (Intranet)
17 septembre 2013, parÀ partir de la version 0.3, un canal de MediaSPIP peut devenir privé, bloqué à toute personne non identifiée grâce au plugin "Intranet/extranet".
Le plugin Intranet/extranet, lorsqu’il est activé, permet de bloquer l’accès au canal à tout visiteur non identifié, l’empêchant d’accéder au contenu en le redirigeant systématiquement vers le formulaire d’identification.
Ce système peut être particulièrement utile pour certaines utilisations comme : Atelier de travail avec des enfants dont le contenu ne doit pas (...) -
Publier sur MédiaSpip
13 juin 2013Puis-je poster des contenus à partir d’une tablette Ipad ?
Oui, si votre Médiaspip installé est à la version 0.2 ou supérieure. Contacter au besoin l’administrateur de votre MédiaSpip pour le savoir -
Support de tous types de médias
10 avril 2011Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

New proposed ePrivacy Regulation and why Piwik might not need tracking consent compared to Google Analytics & co
11 janvier 2017, par InnoCraft — CommunityThe EU is proposing new ePrivacy Regulations. The proposed Regulation on Privacy and Electronic Communications will increase the protection of people’s private life and open up new opportunities for business.
The new ePrivacy Regulation proposal
The proposal mentions several changes for example to the “Cookie Law” where no longer a cookie consent will be needed when the cookies improve the user’s internet experience, for example to remember the shopping cart history or when completing a form over several pages.
However, consent to track a user’s behaviour may be needed in the future, unless the analytics data collection is hosted on the first-party website.
From TheRegister : O’Neil noted a minor change in which visitors to a website for analytics purposes do not require consent, as long as any personal data collected is only processed by the first party.
First party Analytics respecting privacy
Piwik is an open-source analytics platform that is used on more than 1 million websites and apps in over 150 countries, and available in more than 50 languages. The difference with other analytics solutions is that you can download and install Piwik on your own infrastructure. Websites and mobile apps tracking users with their own Piwik very likely won’t require a consent from their users if these regulations become reality.
We have regularly written about why privacy matters, or more recently 11 ways Piwik Analytics helps you to protect your visitors privacy.
Besides the standard Piwik features, there are Premium Features that let businesses and organizations further maximize their success based on the tracked data. Need help in hosting Piwik on premise ? InnoCraft are THE Piwik experts and know it best as it is the company of the makers of Piwik. InnoCraft provides support subscriptions and enterprise packages to help you setting up, configuring and maintaining Piwik on your infrastructure as well as offer training and custom development.
We’re excited to be building the best digital analytics platform which respects our privacy on the Internet.
Thank you for being a valued member of the Piwik community !

Encoding of two full hd streams in Linux + GPU with Intel HD4000 / VA API / FFMPEG / OpenGL
27 juin 2017, par qknighti want to encode/stream two full hd streams in realtime from my laptop to a remote location using linux/xorg on the host.
VA API
for this i’ve been playing with the VA API but the performance is pretty bad with 5.59 fps (see paste below).
FFMPEG
using ffmpeg with CPU encoding i get about 200 fps but then all cores of my Intel(R) Core(TM) i7-3520M CPU @ 2.90GHz are busy and the fan turns on.
future plans
i want GPU support in encoding and later integrate this into a program which streams a virtual xorg ’screen’, see https://lastlog.de/wiki/index.php/Raspberry_PI_virtual_screen for more details on my plans.
maybe h264 isn’t even what i want ? so if someone advices towards a different implementation, i’d welcome that.
besides VA API there seems to be QuickSync but i didn’t experiment with that yet as it is not packaged on NixOS just yet.
note : i need a library to have a smooth integration into the code.
