• Introducing CI Status : the build dashboard for Travis CI

  6 octobre 2014, par Matthieu Napoli — Development, Meta

  The Piwik team has been working on a new tool for developers : CI Status.

  CI Status is a dashboard displaying the latest build status for all your repositories set up on Travis-CI.org or Travis-CI.com. The usage is meant to be as simple as possible : just login using your GitHub account and enjoy.

  CI-status.com

  Give CI Status a try now at ci-status.com !

  

  On your server : Setup CI Status

  The application is open source (released under the GNU Affero General Public License) and developed on GitHub. You are encouraged to contribute to the GitHub project if you find any bug or if you want to add new features. Since it was developed with reusability in mind, you can also install and maintain the application on your own server.

  We hope you will find this tool as useful as we do !

• Piwik SSO options and why is it useful ?

  8 novembre 2017, par Piwik Core Team — Plugins

  Bored with typing again and again different logins and passwords for each service you have access to ? Would you like to add hundreds or thousands of users with different roles to your Piwik at once ? Would you like to save time and effort of managing your users while increasing the security in your business ? Guess what, Piwik has come up with great features to do just that.

  But what is a SSO ?

  Before introducing you to new Piwik features, let me explain what a SSO is.
  SSO is the acronym for Single Sign On. As its name suggests this authentication process allows a user to access multiple applications with one set of login credentials.

  Advantages of using a SSO are numerous :

  • improving security, for example when an employee is leaving your company, how can you check that all his credentials have been removed ?
  • reducing employees time-wasters such as having to enter logins/passwords each time.
  • providing a centralized database for administrators. They can then easily manage permissions of all employees saving them heaps of time.
  • reduces support costs related to authentication / accounts management.

  In order to provide SSO options, two Piwik plugins have been developed and are available on the marketplace :

  • SAML
  • LDAP

  SAML

  

  SAML stands for “Security Assertion Markup Language”, it is a standard in order to exchange authentication and authorization between an identity provider (OneLogin, Okta, Ping Identity, ADFS, Google, Salesforce, SharePoint…) and a service provider.
  An identity provider is an online service that authenticates users on the Internet by using security tokens.

  Are you wondering if your business or organization is using any of these providers ? We recommend to ask your operations team or sysadmin.

  At InnoCraft, we developed a plugin in order to allow SSO with SAML for Piwik. It can ensure consistent access control across the enterprise and external providers, potentially reducing support costs related to authentication and accounts management.

  The installation process is straightforward. All you need is to get the SAML premium feature from the marketplace. Once installed, you will access the SAML configuration interface through the admin where you can configure various settings :

  • SAML Status
  • Identity Provider (Entity ID, SSO endpoint info, Public x509 certificate)
  • Just-in-time provisioning and Mapping attributes
  • Access Synchronization
  • Advanced settings

  

  From there you will need to follow our detailed documentation to have it up and running :
  https://piwik.org/docs/login-saml/.
  Once finished, you will then be able to use SAML to authenticate to your Piwik account :

  

  As all premium features, SAML is eligible to a 30-day period money back guarantee, so do not hesitate to have it a try.

  LDAP

  

  LDAP stands for Lightweight Directory Access Protocol. As its names implies LDAP is a directory, hosted on a server, which organizes the data about people in your company.
  Thanks to the LDAP plugin, Piwik can be connected to your LDAP infrastructure and then use all its power in order to give each individual an access with different rights according to their needs.

  Let’s say that you have 1,000 employees within a company and they all need right now an access to the analytics reports in Piwik with different roles. This is what LDAP can do.

  Moreover if your business or organization is already using LDAP, we recommend using the LDAP connector for Piwik for better security, to stop wasting time of your users and sysadmins, and to reduce the costs related to account management.

  You understood it well. LDAP is a plugin which saves a LOT of time within an organization. Here is a preview of the settings part :

  

  LDAP has been developed by the Piwik core team and is available as a Free plugin on the marketplace.

  If you are surprised by the possibilities that Piwik is offering in terms of plugins, the good news is that many other plugins are waiting for you on the marketplace. Check out our premium marketplace which offers state-of-the-art plugins to get the most out of Piwik.

  And if you are a developer feel free to create your own plugin, a detailed documentation is available at : https://developer.piwik.org/guides/getting-started-part-1.

• Capture CMOS video with FPGA, encode and send over Ethernet

  23 décembre 2015, par ya_urock

  I am planning a open source university project for my students based on Zynq Xilinx FPGA that will capture CMOS video, encode it into transport stream and send it over Ethernet to remote PC. Basically I want to design yet another IP camera. I have strong FPGA experience, but lack knowledge regarding encoding and transfering video data. Here is my plan :

  1. Connect CMOS camera to FPGA, recieve video frames and save them to external DDR memory, verify using HDMI output to monitor. I have no problems with that.

  2. I understand that I have to compress my video stream for example to H.264 format and put into transport stream. Here I have little knowledge and require some hints.

  3. After I form transport stream I can send it over network using UDP packets. I have working hardware solution that reads data from FIFO and sends it to remote PC as UDP papckets.

  4. And finally I plan to receive and play video using ffmpeg library.

     ffplay udp://localhost:5678

  My question is basically regarding 2 step. How do I convert pixel frames to transport stream ? My options are :

  1. Use commercial IP, like
     • http://www.xilinx.com/products/intellectual-property/1-4iso32.html
     • http://www.xilinx.com/products/intellectual-property/1-1lk9j1.html#overview

  Here I doubt that they are free to use and we don’t have much funds.

  2. Use open cores like

     • http://sourceforge.net/projects/hardh264/ - here core generates only h264 output, but how to encapsulate it into transport stream ?
     • I have searched opencores.org but with no success on this topic
     • Maybe somebody knows some good open source relevant FPGA projects ?

  3. Develop harware encoder by myself using Vivado HLS (C Language). But here is the problem that I don’t know the algorithm. Maybe I could gig ffmpeg or Cisco openh264 library and find there a function that converts raw pixel frames to H.264 format and then puts it into transport stream ? Any help would be appriciated here also.

  Also I am worried about format compatibility of stream I might generate inside FPGA and the one expected at host by ffplay utility. Any help, hints, links and books are appriciated !
