• The ultimate solution to knowing how your business is performing overall

  8 janvier 2018, par InnoCraft — Community, Plugins

  Would you like to know how your business is performing overall at a glance ? Guess what, you can now do this easily with Roll-Up Reporting.

  What is Roll-Up Reporting about ?

  Roll-Up Reporting is a premium feature which you can acquire through the Piwik Marketplace. Developed by InnoCraft, the professional company behind Piwik, this plugin will :

  1. Save you heaps of time and gives you completely new insights
  2. Make this process easy as pie
  3. Reflect the structure of your business or organization

  1 – Roll-Up Reporting does the maths for you

  Yes, you read it right. Compared to having to sum reports of multiple websites manually, you can get aggregated results for your business or departments instantly with a single click directly in Piwik. Not only does this save you heaps of time compared to doing this complicated work in a spreadsheet, you also avoid human errors. With this feature, you get a clear overview over all your websites, apps, and shops performances.

  For example, if you want to know which referrers bring you the most value across all websites, then you will get the answer in a report. Same results for e-commerce reports, actions, and other metrics.

  2 – Easy as pie, no tracking code involved

  The best part of this feature is that you do not need to push data through additional tracking code. The setup is simple and made through the UI of the plugin.

  3 – Roll-Up Reporting meets even the hardest requirements

  You can also create “nested roll-ups”. This feature allows you to create a roll-up consisting of several other roll-ups. With a nested roll-up, you can create a roll-up for each department in your company (and assign all the websites of a department to that roll-up), then group several departments easily into a new roll-up simply by assigning several department roll-ups to this new roll-up.

  

  For example, a company with multiple brands can assign multiple websites to each brand, and then get aggregated results for each brand and for the business overall. As a roll-up is basically the same as a website, you can give users access to a roll-up without having to give them access to each site, and the other way around.

  How does it work ?

  As with all premium features, this plugin is straightforward to use. Once activated in your Piwik administrator panel, you will notice that when you add a website, you have the choice between two possibilities :

  

  When you select the “Roll-Up” option, a new window will appear asking you which websites and mobile apps you would like to aggregate into a roll-up :

  

  The created roll-up will then be shown just like any other website that you have in Piwik. You can create as many roll-up entities as you want.

  

  Features, such as custom alerts, segments, and e-mail reports work for a roll-up just like for any website.

  Real-Time reports

  One of the most interesting features of Roll-Up Reporting is, that you can view all the Real-Time reports, such as the “Visitors in Real-Time” widget, the “Real-Time Map”, and the “Visitor Log” across several websites making it much easier to keep an eye on your business :

  

  How to get the Roll-up reporting plugin ?

  Developed by InnoCraft, the makers of Piwik, Roll-Up Reporting is a premium feature which you can purchase on the Piwik Marketplace. You can also try it for free on the Piwik Cloud for 30 days.

• Xvfb + ffmpeg/aconv not working

  29 décembre 2017, par ipauler

  I’m trying to capture screen using xvfb + aconv.
  I’’m using docker to run image. I’ve tried almost everything to make it working, different ubuntu images Debian Centos, different images from docker hub.
  My last build is simple ubuntu:trusty(14.04) image + xvfb + avconv

  FROM ubuntu:trusty
  
  RUN echo "deb http://ppa.launchpad.net/mozillateam/firefox-next/ubuntu trusty main" > /etc/apt/sources.list.d//mozillateam-firefox-next-trusty.list
  
  RUN apt-key adv --keyserver keyserver.ubuntu.com --recv-keys CE49EC21
  
  RUN apt-get update
  
  RUN apt-get install -y firefox xvfb python-pip
  
  RUN pip install selenium
  
  RUN mkdir -p /root/selenium_wd_tests
  
  #ADD sel_wd_new_user.py /root/selenium_wd_tests
  
  ADD xvfb.init /etc/init.d/xvfb
  
  RUN chmod +x /etc/init.d/xvfb
  
  RUN update-rc.d xvfb defaults

  I installed avcnov through apt-get
  then I run Xvfb

  Xvfb -ac :99 -screen 0 1280x1024x24

  and firefox
  Then I just run

  avconv -f x11grab -r 25 -s 1280x1024 -i :99 -vcodec libx264 -threads 4 $HOME/output.avi

  and nothing happens, avconv is stuck it doesn’t starts capturing

  avconv version 9.20-6:9.20-0ubuntu0.14.04.1, Copyright (c) 2000-2014 the Libav developers
  
    built on Dec  7 2016 21:22:31 with gcc 4.8 (Ubuntu 4.8.4-2ubuntu1~14.04.3)
  
  [x11grab @ 0x2189c60] device: :99 -> display: :99 x: 0 y: 0 width: 1280 height: 1024

  Anybody please any advice, i’ve spent 4 days trying to make it work.
  Thanks.

• FFMPEG command runs forever even on using timelimit

  21 décembre 2017, par t6nand

  Mostly I use a java code to run FFMPEG bash commands for watermarking a logo on video. I am using the following FFmpeg command to overlay an image on video. I have observed that at times for some random videos, the process keeps on running even after the timelimit assigned to it expires. At times it’s more than a day or couple of days until not directly killed using kill -9 pid :

  ffmpeg -timelimit 900 -y -i
  input_video
  -i logoImage -filter_complex "[0:v]scale=trunc(iw/2)*2:trunc(ih/2)*2[even] ;[1:v][even]scale2ref=iw*0.25 :(iw*0.25)*(0.46446702)[2nd][ref] ;[ref][2nd]overlay=(main_w-overlay_w) :(main_h-overlay_h)"
  -c:v libx264 -b:v 300K -crf 28 -preset slow outputVideo

  But this command never completes even on using -timelimit flag at times for some videos.

  I have observed that for such processes output from ps aux|grep ffmpeg yeilds in something like :

  ubuntu 16620 0.6 6.7 1595044 515392 ? Sl Dec20 12:05
  ffmpeg -timelimit 900 -y -i
  input_video
  -i logoImage -filter_complex "[0:v]scale=trunc(iw/2)*2:trunc(ih/2)*2[even] ;[1:v][even]scale2ref=iw*0.25 :(iw*0.25)*(0.46446702)[2nd][ref] ;[ref][2nd]overlay=(main_w-overlay_w) :(main_h-overlay_h)"
  -c:v libx264 -b:v 300K -crf 28 -preset slow outputVideo

  It indicates that this process is in interruptible sleep state i.e. waiting for an event to complete. On using sudo strace -p 16620 to trace which system call is this process hung up on it results in something like :

  Process 16620 attached write(2, "frame= 4121 fps= 10 q=33.0 size="...,
  99

  i.e. it’s stuck writing to a file.

  What could be the reason for this problem ?
  And is there any other way to kill FFMPEG process which overshoots desired time limit ?
