• Linker error using FFMPEG with Visual Studio 2013 Express

  19 décembre 2013, par Andres

  I am trying to write a program using FFMPEG libraries. I read about in this link. I downloaded Shared and Devs files from http://ffmpeg.zeranoe.com/builds/.

  I created a console project and this is the configuration :

  Additional Libraries Directories
  

  Additional Include Directories
  

  And here is my code :

  #include "stdafx.h"
  
  #pragma comment (lib, "avformat.lib")
  
  #pragma comment (lib, "avcodec.lib")
  
  #pragma comment (lib, "avutil.lib")
  
  
  
  extern "C"
  
  {
  
      #ifndef __STDC_CONSTANT_MACROS
  
      #define __STDC_CONSTANT_MACROS
  
      #endif
  
      #include 
  
      #include 
  
      #include 
  
      #include 
  
  }
  
  int _tmain(int argc, _TCHAR* argv[])
  
  {
  
      av_register_all();
  
      return 0;
  
  }

  And the error I am getting is this :

  Error 1 error LNK2019 : unresolved external symbol _av_register_all
  referenced in function _wmain C :\Users\Andres\Documents\Visual Studio
  2013\Projects\PruebaFFMPEG\PruebaFFMPEG\PruebaFFMPEG.obj PruebaFFMPEG

  Error 2 error LNK1120 : 1 unresolved
  externals C :\Users\Andres\Documents\Visual Studio
  2013\Projects\PruebaFFMPEG\Debug\PruebaFFMPEG.exe PruebaFFMPEG

  What am I missing ?

• Anomalie #2013 (En cours) : Limiter la previsu en redaction à ses propres articles

  17 décembre 2013, par Fil Up

  Le fix répond à une demande précise, qu’il faut prendre en compte : le besoin pour 1 rédacteur de pouvoir prévisualiser son propre article.

  Mais ce faisant, il ouvre la lecture à tous les rédacteurs de tous les articles en préparation.

  Sur un site comme uZine (†), cela aurait été gênant, car des rédacteurs extérieurs, invités à contribuer, ne sont pas censés avoir accès aux brouillons de tout le monde.

  Il me semblerait plus cohérent, si on veut prévisualiser son propre article, de passer cette demande sous forme d’argument dans l’URL de prévisu, qui "valide" cet article précisément au niveau du compilo, avec un truc du genre `statut IN (publie,prop) OR id_article=mon article`.

• [Aug-Sept 2013] Piwik 2.0 Development Update !

  3 octobre 2013, par Fabian Becker — Development

  This Development Update is the first in a new series of posts we’ll be writing to keep you, our loyal users, informed of our efforts. We hope these updates keep you excited about Piwik’s future, and if you’re a developer, we hope they inspire and challenge you to accomplish more yourself !

  Despite this being our first update, it will probably be one of our biggest. We’ve gotten a lot done as we race towards the Piwik 2.0 release ! Just see for yourself :

  What we’ve accomplished

  Theming

  Piwik now supports theming, a feature that was requested often in the past. Because of our switch to the Twig template engine and other major code changes it is now possible to change the way Piwik looks. Additionally, developers can use the dynamic stylesheet language LESS, instead of CSS. Piwik will automatically transform the LESS code into CSS.

  Piwik 2.0 will ship with a new dark theme called PleineLune (french for Full Moon) that makes use of the new theming feature. Another theme with a left-aligned menu was created during the Piwik Meetup in Paris. Both of these themes were created by Thomas Zilliox, a very talented designer and CSS expert.

  

  PHP 5.3 Namespaces

  For Piwik 2.0 we decided to make use of namespaces, a feature introduced in PHP 5.3. The usage of namespaces makes our code more readable and allows us to better modularize the platform. This is in part why we are raising the required minimum PHP version to 5.3 for Piwik 2.0. (Remember to update your server !)

  Translations in JSON

  All translations are now stored in JSON files which makes storing translations in Piwik a lot cleaner that the giant PHP array we previously used.

  Side note : if you’d like to make Piwik available to more languages, please sign up at translations.piwik.org. We’d love to have your help !

  UI Tests

  We now use UI tests to make sure that changes to the code don’t break the UI. UI tests use PhantomJS and CutyCapt and are automatically executed on Travis CI. Whenever an integration test fails the script produces a screenshot diff that shows the difference. Learn more.

  

  AnonymizeIP supports IPv6

  The AnonymizeIP plugin now masks IPv6 addresses. The concept of the config option ‘ip_address_mask_length’ has now changed to reflect the level of masking that should be applied to the IP. With a masking level of 1 Piwik will mask the last octet of an IPv4 address and the last 80 bits of an IPv6 address.

  All Websites Dashboard usable with 20,000+ Websites

  The All Websites Dashboard is now usable even if you track many thousands of websites in your Piwik instance. We rewrote parts of the archiving process in order to make this possible. Making Piwik fast and memory efficient is a constant concern for core developers.

  Plugins can now add new Visualizations

  Piwik Plugins and Themes can now create new visualizations for your report data. They can also specify their own ViewDataTable footer icons or modify existing ones. This will allow plugin developers to create new ways for you to view your data, customize existing reports so they look great in new visualizations and provide extra analytics functionality accessible in each of your reports.

  The new TreemapVisualization plugin makes use of this feature to let you view your reports as treemaps. It serves as an example of this new functionality.

  Piwik Marketplace

  The Piwik Marketplace is a new platform developers can use to publish their plugins and themes so all Piwik users can easily access them. The marketplace is hosted at plugins.piwik.org and is currently in an early development state, but we’re already able to host plugins !

  Developers can easily publish their plugins by adding a commit hook to their Github repositories. Every time you push a new tag, the marketplace will make a new version of your plugin available. The marketplace will provide a centralized platform to search for plugins and also provide statistics on plugin usage.

  Install Plugins and Themes in one click from within Piwik

  Piwik has offered since the beginning the much-loved “one click update” feature. We are bringing the same functionnality to the Marketplace : you will be able to install Plugins and Themes in one click directly within the Piwik interface ! Similarly to WordPress or Firefox, Piwik will let you extend the functionnality of your analytics platform.

  Conclusion

  In Piwik 2.0 you will be able to install plugins and themes from the marketplace. And, if you’re so inclined, you will be able to create and host your own plugins/themes on the marketplace so everyone can use them. This is by far the accomplishment we are most excited by… the possibilities it opens up for Piwik’s future are truly unlimited. We hope you share our excitement !

  Au revoir, until next time !

  PS : our mission is to liberate web analytics ; thank you for sharing the word about Piwik 2.0 !
