• Spotlight : Alwaysdata.com the company behind Piwik.org web hosting [Interview]

  11 avril 2013, par matt — About, Community

  Piwik is the result of the work of many talented individuals and companies. Today we’d like to showcase Alwaysdata.com, the awesome web hosting company providing managed hosting for all Piwik.org websites and services.

  I recently met and asked a few questions to Cyril, co-founder of Alwaysdata.com and Piwik core developer. Learn more in the interview below !

  

  1. What is Alwaysdata ?
  2. Who are your customers and what kind of work do you do ?
  3. What sets Alwaysdata apart from the large web hosting competition ?
  4. Are you using Piwik internally or with customers ? If so, how are you using Piwik ?
  5. What is the next big thing for Alwaysdata ?
  6. Learn more

  What is Alwaysdata ?

  We are a French web hosting company created in 2006. If you need to host a website — a Piwik installation, for example — or even your domains/emails, we provide infrastructure and maintenance services.

  Who are your customers and what kind of work do you do ?

  We have several types of clients :

  • Individuals who need hosting for their personal site and who benefit from storage space with direct SSH access.
  • Web agencies who need hosting for their clients’ sites.
  • The largest customers, often on dedicated servers, for hosting their site/infrastructure.

  Our work falls into three categories :

  1. Support (via administration, telephone, Twitter, IRC, etc.)
  2. Development (in Python), primarily to add new features
  3. System administration, either for maintenance (e.g. adding servers), or for preparing new features

  What sets Alwaysdata apart from the large web hosting competition ?

  Two things :

  • Availability. We are a small team and often know our customers quite well. We are all on IRC, so you can contact us directly if you need any assistance.
  • Features. We are halfway between traditional web hosting and the cloud, combining the advantages of both.

  Are you using Piwik internally or with customers ? If so, how are you using Piwik ?

  All of our customers can view statistics for their sites via our global Piwik installation, without having to configure anything.

  To provide these analytics reports to our customers, we implemented import of the raw access logs in Piwik. The Log import toolkit is now a feature included in Piwik.

  What is the next big thing for Alwaysdata ?

  We are going to upgrade our pricing : instead of fixed costs, each of our clients will now pay exactly what they consume. This allows our clients the benefit of a very high quality service for the lowest possible price.

  We are also going to add native support for more technologies : Java, Node.js, ZeroMQ, etc.

  Thank you for your time and all the best to Alwaysdata for the future !

  Note from Matt, Piwik founder : Cyril and the team at Alwaysdata.com have been consistently great in their system administration work for Piwik.org services, providing a fast and reliable web hosting experience with top notch support and security practises. They also handled the migration of all services from our old servers with total piece of mind.

  Alwaysdata contributed to Piwik the popular Log Analytics toolkit. They are great software developers and system administrators with a passion for their work. Since 2006, they have been maintaining optimized hosting services for the entire web infrastructure (websites, domains, emails, databases, etc.), from the simplest to the most exotic. We do recommend their managed hosting services.

• video snapshot generating horizontally in node js.

  2 février 2016, par iam

  I am using FFMPEG for generating snapshot of video but problem is that snapshot is capturing horizontally i want it to vertical.

  code

  pathToFile = path+name;
  
          pathToSnapshot = path+'sshot.jpg';
  
  
  
            // Also a default node module
  
  
  
            require('child_process').exec(('ffmpeg -i '+ pathToFile +' -vframes 1 -s 450x450 -ss 02 '+ pathToSnapshot), function () {});  

• Conversion does not end using ffmpeg on Android device

  3 février 2016, par Belhaver

  I am trying to make an application with usage of ffmpeg-android-java https://github.com/WritingMinds/ffmpeg-android-java and i have a problem. File conversion just does not end.

  Here is code which i am using :

  try {
  
      // code...
  
          String commandStr = "-y -i /storage/emulated/0/input.mp4 -strict experimental -s " + fileWidth + "x" + fileHeight + " -vcodec libx264 -r 30 /storage/emulated/0/output.mp4";
  
  
  
          ffmpeg.execute(commandStr, new ExecuteBinaryResponseHandler() {
  
              @Override
  
              public void onSuccess(String message) {
  
                  Log.d("FFMPEG success", "");
  
                  // code...
  
              }
  
  
  
              @Override
  
              public void onFailure(String message) {
  
  
  
                  Log.d("FFMPEG failure: ", message);
  
                  // code...
  
              }
  
  
  
              @Override
  
              public void onProgress(String message) {
  
                  Log.d("FFMPEG process: ", message);
  
              }
  
  
  
              @Override
  
              public void onFinish() {
  
                  Log.d("FFMPEG done", "");
  
              }
  
          });
  
      } catch (Throwable e) {
  
          e.printStackTrace();
  
      }

  Here is the output process :
