• 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.

• Working with ffmpeg in Xamarin Android

  8 janvier 2018, par Ahmed Mujtaba

  I’m building an android app using Xamarin. The requirement of the app is to capture video from the camera and encode the video to send it across to a server. Initially I was using an encoder library on the server side to encode recorded video but it was proving to be extremely unreliable and inefficient specially for large sized video files. I have posted my issues on another thread here I then decided to encode the video on the client side and then send it to the server. I’ve found encoding to be a bit complicated and there isn’t much information available on how this can be done so I search for the only way I knew how to encode a video that is by using ffmpeg codec. I’ve found some solutions. There’s a project on github that demonstrates how ffmpeg is used inside a Xamarin android project. However running the solution doesn’t give any output. The project has a binary ffmpeg file which is installed to the phone directory using the code below :

  _ffmpegBin = InstallBinary(XamarinAndroidFFmpeg.Resource.Raw.ffmpeg, "ffmpeg", false);

  Below is the example code for encoding video into different set of outputs :

              _workingDirectory = Android.OS.Environment.ExternalStorageDirectory.AbsolutePath;
  
          var sourceMp4 = "cat1.mp4";
  
          var destinationPathAndFilename = System.IO.Path.Combine (_workingDirectory, "cat1_out.mp4");
  
          var destinationPathAndFilename2 = System.IO.Path.Combine (_workingDirectory, "cat1_out2.mp4");
  
          var destinationPathAndFilename4 = System.IO.Path.Combine (_workingDirectory, "cat1_out4.wav");
  
          if (File.Exists (destinationPathAndFilename))
  
              File.Delete (destinationPathAndFilename);
  
          CreateSampleFile(Resource.Raw.cat1, _workingDirectory, sourceMp4);
  
  
  
  
  
          var ffmpeg = new FFMpeg (this, _workingDirectory);
  
  
  
          var sourceClip = new Clip (System.IO.Path.Combine(_workingDirectory, sourceMp4));
  
  
  
          var result = ffmpeg.GetInfo (sourceClip);
  
  
  
          var br = System.Environment.NewLine;
  
  
  
          // There are callbacks based on Standard Output and Standard Error when ffmpeg binary is running as a process:
  
  
  
          var onComplete = new MyCommand ((_) => {
  
              RunOnUiThread(() =>_logView.Append("DONE!" + br + br));
  
          });
  
  
  
          var onMessage = new MyCommand ((message) => {
  
              RunOnUiThread(() =>_logView.Append(message + br + br));
  
          });
  
  
  
          var callbacks = new FFMpegCallbacks (onComplete, onMessage);
  
  
  
          // 1. The idea of this first test is to show that video editing is possible via FFmpeg:
  
          // It results in a 150x150 movie that eventually zooms on a cat ear. This is desaturated, and there's a fade in.
  
  
  
          var filters = new List<videofilter> ();
  
          filters.Add (new FadeVideoFilter ("in", 0, 100));
  
          filters.Add(new CropVideoFilter("150","150","0","0"));
  
          filters.Add(new ColorVideoFilter(1.0m, 1.0m, 0.0m, 0.5m, 1.0m, 1.0m, 1.0m, 1.0m));
  
          var outputClip = new Clip (destinationPathAndFilename) { videoFilter = VideoFilter.Build (filters)  };
  
          outputClip.H264_CRF = "18"; // It's the quality coefficient for H264 - Default is 28. I think 18 is pretty good.
  
          ffmpeg.ProcessVideo(sourceClip, outputClip, true, new FFMpegCallbacks(onComplete, onMessage));
  
  
  
          //2. This is a similar version version in command line only:
  
          string[] cmds = new string[] {
  
              "-y",
  
              "-i",
  
              sourceClip.path,
  
              "-strict",
  
              "-2",
  
              "-vf",
  
              "mp=eq2=1:1.68:0.3:1.25:1:0.96:1",
  
              destinationPathAndFilename2,
  
              "-acodec",
  
              "copy",
  
          };
  
          ffmpeg.Execute (cmds, callbacks);
  
  
  
          // 3. This lists codecs:
  
          string[] cmds3 = new string[] {
  
              "-codecs",
  
          };
  
          ffmpeg.Execute (cmds, callbacks);
  
  
  
          // 4. This convers to WAV
  
          // Note that the cat movie just has some silent house noise.
  
          ffmpeg.ConvertToWaveAudio(sourceClip, destinationPathAndFilename4, 44100, 2, callbacks, true);
  
  </videofilter>

  I have tried different commands but no output file is generated. I have tried to use another project found here but this one has the same issue. I don’t get any errors but no output file is generated. I’m really hoping someone can help me find a way I can manage to use ffmpeg in my project or some way to compress video to transport it to the server.

  I will really appreciate if someone can point me to the right direction.

• Piwik Analytics becomes Matomo to reflect Users’ Privacy Focus

  10 janvier 2018, par Matomo Core Team

  One of the world’s leading analytics software platforms is changing its name. Piwik is the sixth most-used web and mobile analytics computer solution worldwide. It is now changing its name to Matomo.

  The name change comes after 10 years of Piwik building its top analytics software, with great success. It is already used on over one million websites in more than 170 countries. Matomo will build on that success, and focus even more on privacy.

  ‘Privacy has become a huge concern worldwide’, says Matomo’s creator, Matthieu Aubry. ‘Privacy legislation is being developed in Europe, and we will be ahead of the game in being ready for those changes. We’ll grow in line with the law and regulation changes.’

  Matomo will lead the way in openness and transparency for its users. Its new name means honesty in Japanese.
  ‘Matomo will always be free and community-driven, just as Piwik was’, says Matthieu Aubry. ‘We have worked with hundreds of people to create the best open digital analytics solution in the world. We’re committed to giving every user full control of their data.’

  The change of name is appropriate as the Matomo platform moves into a new stage of growth. But for its community, little will obviously change. The same people will still be involved, and users will still get useful data to improve their own website. That data includes who visits their site, what they do there, how long they stay, and what they buy.
  Matomo is an all-in-one analytics solution that gives companies a 360 degree view of their users.

  ‘They can grow their business while still keeping 100% ownership of their data, and being fully compliant with privacy laws’, says Matthieu Aubry. ‘We’re more motivated than ever to building on that, so that Matomo stays ahead of the pack.’

  The platform can be fully customised with hundreds of plug-ins, integrations and configurations.

  Matomo’s updated website and new logo is now available on https://matomo.org.
