  • 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.

    Pictures from the meetup preparation sessions

    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.

    More pictures from the Piwik meetup

    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 :

    On Tuesday we met again to discuss the following subjects :

    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

  • VLC command line : RTSP to mp4 file (video + audio)

    8 février 2016, par Dmitriy Gerashenko

    Win 7 x64.

    When I watch this link in VLC player all is fine :

    rtsp ://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov

    When I try to capture link to file and to display :

    • There is video without sound on display.
    • Created file is not playable.

    Command :

    vlc.exe -vvv "rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov" --sout="#transcode{venc=ffmpeg,vcodec=mp4v,vfilter=canvas{width=800,height=600},aenc=ffmpeg{strict=-2},acodec=mp4a}:duplicate{dst=display,dst=standard{access=file,mux=mp4,dst=video.mp4}"

    There are some errors in log, for example : MPEG4GenericRTPSource Warning: Unknown or unsupported "mode": AAC-hbr. Is it cause of my problems ? How to solve my issue ?

  • Set the time according to the image height

    5 août 2019, par Võ Nhân

    I am creating video from the image using ffmpeg, I have some problems with image height and video length, I want to set the time automatically according to the image length.Is it possible to set the time -t to the automatic value ?

    ffmpeg -y -loop 1 -i "{output}_cut1.jpg" -ss 0 -t 25 -r 1 -loop 1 -i 01.png -ss 0 -t 25 -filter_complex " [1:v] scale=w=1:h=1[fg]; [0:v] scale=w=-2:h=3*ih, crop=w=3*1988:h=3*1600/1.2:y=t*(in_h-out_h)/25 , scale=w=1920:h=1080,  setsar=1 [bg] ; [bg][fg]overlay=shortest=1[v] " -map "[v]" -c:v h264 -crf 18 -preset ultrafast "{output}_cut1.mp4"
