• A *hot* Piwik Community Meetup 2015 !

  10 août 2015 — Community

  Last weekend I arrived in Germany to attend the Piwik Community Meetup 2015 and now I am in Poland. I joined Piwik PRO back in May as enterprise support project coordinator in North America. I am now writing this from the Piwik PRO main office in Wrocław, where I’ll be working from for the next two weeks.

  The meetup was HOT in every sense ! Berlin temperatures reached 35 degrees (celsius), as I finally meet in person several long-time, dedicated Piwik community contributors.

  In the first leg of my trip I was in Berlin to meet Piwik community members and Piwik PRO staff to prepare for the 2015 annual Piwik community meetup. These are my notes taken during the meeting at the request of one of my colleagues. I also relayed live on Framasphère, Twitter and IRC.

  This was harder than I expected, as I took notes with my laptop, pictures with my phone, wrote live to social media (using the Android Diaspora Native Web App), and used my laptop to relay on IRC. Going forward this requires better preparation, I was glad I had a few links and pictures ready before hand but it really requires intense focus to achieve this. I am glad presenters were patient when I requested repeating some of the ideas they shared. I am also a bit disappointed not much happened in IRC.

  Two day preparation sessions

  The discussions and session we had during the two days prior to the meetup are available here.

  We gathered in rented apartments in Berlin, this reminded me very much of similar community gatherings and perhaps of BarCamp and, at a much smaller scale, UDS sessions.

  A list of ideas of topics was initially submitted, we then proceeded to have scheduled sessions for open discussion. Several people shared their concern there was no possible remote participation which led to making public the Trello boards used/linked here.

  Note : The Trello links below still have action items and notes that are pending bug report / feature requests filing which should happen over the coming weeks. Most importantly, many action items will need identifying leads for different community team including Translations and Documentation, and better coordination of coming community engagement.

  Monday sessions consisted of the following subjects :

  • What are Piwik values & how to communicate them ? (see below for details)
  • How to encourage and recognize new external contributors ?
  • How could we double the Piwik userbase ?
  • How Community can organise help resources

  On Tuesday we met again to discuss the following subjects :

  • Piwik Long Term support (LTS)
  • How do Piwik.org (project) and Piwik PRO (company) sit together / are organized ? – An important part of this session was about having better communication channels and improving the new team page (bug #8520 and bug #8519, respectively)
  • Improving usability of Piwik e.g. for new users – this last session was not held has we ran out of time and prepared to go to the meetup venue.

  Some more details about individual preparation sessions

  What are Piwik values & how to communicate them ?

  The main subjects in this session were important changes proposed in the project mission and values. This was edited directly on on the wiki page on GitHub, some of the changes can be seen by comparing revisions.

  Piwik mission statement (bug #7376)

  “To create the leading Free and open source analytics platform, and to support global organisations and communities to keep full control over their data.”

  Our values

  • Openness
  • Freedom
  • Transparency
  • Data ownership
  • Privacy
  • Kaizen (改善) : continuous improvement

  This was also presented by Matthieu Aubry at the meetup and is published in the Roadmap page. Bringing more visibility and perhaps having a top page for Mission and Values was also brought up.

  Meetup agenda and notes

  The official agenda is available here.

  Many Piwik PRO employees stayed in Berlin for the meetup, and we had good participation although less than last year in Munich as my colleagues told me. Some were consultants, others staff from public organizations, universities, etc. In retrospect considering the very hot weather and summer holidays the attendance was good. I was very happy to arrive at the beautiful Kulturbrauerei and enter the air-conditioned Soda Club. T-Shirts were waiting for all attendees and free drinks (non-alcohol !) were welcome

  the tutorial code was update to work on new ffmpeg versions.I’m using VM Ubuntu 16.0.4 64 bit fresh install on windows 10 host.

  so why I’m having all of these errors ?

  Update :
  I moved to Ubuntu 12.04 VM and ffmpeg 0.11, I instilled it with opencv 2.4.2 here is the link . This should work yet i don’t why I’m having hard time compiling such small program.

  Update2

  I changged avcodec_free_frame to av_free and the file complied

  Dranger code is old

  Update 3
  i downloaded ffmpeg 1.0.10 which has the same library version that is the tutorial tested on. Everything complied without any problem now.

• Building my JAVA parameter array for FFMPEG

  29 janvier 2016, par user3541092

  FFmpeg Version : N-63893-gc69defd Copyright (c) 2000-2014 the FFmpeg developers
  built on Jul 16 2014 05:38:01 with gcc 4.6 (Debian 4.6.3-1)

  Machine : Amazon Linux t2.micro (free tier)

  Sample File : sample_iTunes.mov
  Sample File URL : https://support.apple.com/en-us/HT201549

  I’m trying to replicate the following FFmpeg command, using a string array and then pass this array into the Runtime.getRuntime().exec().

  ffmpeg -i file:/var/local/ffmpegtest/media_input/sample_iTunes.mov -pix_fmt yuv420p -c:v libx264 -vtag mp42 -metadata major_brand="mp42" -b:v 8000k -minrate 8000k -maxrate 10000k -ac 2 -strict experimental -c:a aac -b:a 256k -metadata:s:a:0 handler="Stereo" /var/local/ffmpegtest/media_output/sample_iTunes.mp4 -y

  NOTE : This works when I pass the full command, as a single string into Runtime.getRuntime().exec().

      String _cmd = "ffmpeg -i %s -pix_fmt yuv420p -c:v libx264 -vtag mp42 -metadata major_brand=\"mp42\" "
  
              + "-b:v 8000k -minrate 8000k -maxrate 10000k -ac 2 -strict experimental -c:a aac -b:a 256k -metadata:s:a:0 handler=\"Stereo\" %s -y";
  
      String _ffmpegCommand = String.format(_cmd, _inputFile, _outPutFile);
  
      p = Runtime.getRuntime().exec(_ffmpegCommand);
  
      BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
  
  
  
      String _line = null;
  
  
  
      while((_line = _reader.readLine()) != null) {
  
          lw.writeLine(_logPath + _logName, _line);
  
          System.out.println(_line);
  
      }

  I started out with just a basic parameter list. As I add add each additional parameter, I re-build the JAR file and upload it to my EC2 instance to test for any errors.

  The following string array works :

  try
  
          {
  
              String[] _params = {"ffmpeg",
  
                         "-i",
  
                         String.format("%s", _inputFile),
  
                         "-pix_fmt",
  
                         "yuv420p",
  
                         "-c:v",
  
                         "libx264",
  
                         String.format("%s", _outPutFile),
  
                         "-y"};
  
  
  
              p = Runtime.getRuntime().exec(_params);
  
  
  
              BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
  
  
  
              String _line = null;
  
  
  
              while((_line = _reader.readLine()) != null) {
  
                  lw.writeLine(_logPath + _logName, _line);
  
                  System.out.println(_line);
  
              }
  
          }
  
          catch (Exception e) {
  
              BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
  
  
  
              String _line = null;
  
  
  
              while((_line = _reader.readLine()) != null) {
  
                  lw.writeLine(_logPath + _logName, _line);
  
                  System.out.println(_line);
  
              }
  
  
  
          }

  However, when I continue to build the array with additional parameters, I begin to experience problems (lets add -vtag mp42) :

  try
  
          {
  
              String[] _params = {"ffmpeg",
  
                         "-i",
  
                         String.format("%s", _inputFile),
  
                         "-pix_fmt",
  
                         "yuv420p",
  
                         "-c:v",
  
                         "libx264",
  
                         "-vtag", // <---- New
  
                         "mp42", // <---  New
  
                         String.format("%s", _outPutFile),
  
                         "-y"};
  
  
  
              p = Runtime.getRuntime().exec(_params);
  
  
  
              BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
  
  
  
              String _line = null;
  
  
  
              while((_line = _reader.readLine()) != null) {
  
                  lw.writeLine(_logPath + _logName, _line);
  
                  System.out.println(_line);
  
              }
  
          }
  
          catch (Exception e) {
  
              BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
  
  
  
              String _line = null;
  
  
  
              while((_line = _reader.readLine()) != null) {
  
                  lw.writeLine(_logPath + _logName, _line);
  
                  System.out.println(_line);
  
              }
  
  
  
          }
