• How you can use the Piwik AOM plugin to improve your data and make better online marketing decisions

  13 septembre 2017, par André Kolell — Plugins, AdWords, Bing, Case Study, Criteo, eccommerce tracking, Facebook Ads, how to install piwik analytics, how-to piwik, integration, piwik, Taboola

  Hi, this is André, one of the authors of the Piwik Advanced Online Marketing plugin, which has just hit 5,000 downloads on the Piwik marketplace. In this blog post I’ll show you how Piwik AOM improves your data and enables you to make better online marketing decisions.

  Piwik itself is excellent in tracking all kinds of visitor data, like where a visitor is coming from and what he’s doing on your page or app (pageviews, events, conversions). But what Piwik did not yet take a closer a look at, is how much you’ve invested into your marketing activities and how profitable they are.

  With the Piwik AOM plugin you can integrate data like advertising costs, advertising campaign names, ad impressions etc. from advertising platforms (such as Google AdWords, Microsoft Bing, Criteo, Facebook Ads and Taboola) and individual campaigns (such as such as cost per view/click/acquisition and fixed price per months deals) into Piwik and combine that data with individual Piwik visits.

  Piwik AOM adds a new marketing performance report to Piwik giving you a great overview of all your marketing activities with drill-down functionality :

  

   

  When taking a look at a specific visitor, Piwik AOM shows you the exact cost of acquiring a specific visit :

  

   

  Leveraging Piwik AOM’s full potential

  But although you can access Piwik AOM’s valuable data directly in the Piwik UI for ad-hoc analyses, Piwik AOM’s true strength comes into play when working with the raw data in an external business intelligence application of your choice, where you can further integrate Piwik AOM’s data with your most accurate backend data (like conversion’s contribution margins after returns, new vs. existing customer, etc.).

  Piwik AOM offers some API endpoints that allow you to fetch the data you need but you can also retrieve it directly from Piwik AOM’s aom_visits table, which includes all visits, all allocated advertising costs and advertising campaign details. As there is never data being deleted from aom_visits, the table can easily be connected to your ETL tool with its last update timestamp column. A third way to get data out of Piwik AOM is by developing your own Piwik plugin and listening to the AOM.aomVisitAddedOrUpdated event, which is posted whenever an aom_visits record is added or updated.

  Integrating Piwik AOM’s data with your backend data in the business intelligence application of your choice allows you to evaluate the real performance of your online marketing campaigns when applying different conversion attribution models, conduct customer journey analyses, create sophisticated forecasts and whatever you can think of.

  AOM Use case

  A company that followed this approach, is FINANZCHECK.de, one of Germany’s leading loan comparison websites. At the eMetrics summit 2016 in Berlin, Germany, I gave a talk about FINANZCHECK’s architectural online marketing setup. Until recently, FINANZCHECK used Pentaho data integration to integrate data from Piwik, Piwik AOM and additional internal tools like its proprietary CRM software into Jaspersoft, its data warehouse an BI solution. The enriched data in Jaspersoft was not only used for reporting to various stakeholders but also for optimising all kinds of marketing activities (e.g. bids for individual keywords in Google AdWords) and proactive alerting. Not long ago, FINANZCHECK started an initiative to improve its setup even further – I’ll hopefully be able to cover this in a more detailed case study soon.

  Roadmap

  In the past, we had the chance to make great progress in developing this plugin by solving specific requirements of different companies who use Piwik AOM. During the next months, we plan to integrate more advertising platforms, reimplement Facebook Ads, improve the support of individual campaigns and work on the general plugin stability and performance.

  Before you install Piwik AOM

  Before installing Piwik AOM, you should know that its initial setup and even its maintenance can be quite complex. Piwik AOM will heavily modify your Piwik installation and you will only benefit from Piwik AOM if you are willing to invest quite some time into it.

  If you are not familiar with Piwik’s internals, PHP, MySQL, database backups, cronjobs, creating API accounts at the advertising platforms or adding parameters to your advertising campaign’s URLs, you should probably not install it on your own (at least not in your production environment).

  Piwik AOM has successfully been tested with up to 25k visitors a day for a period of more than two years, running on an AWS server with 4 GB RAM, once CPU and a separate AWS RDS MySQL database.

• Encoding video for streaming with multiple subtitle streams in VLC

  7 janvier 2018, par VinGarcia

  I am implementing an offline video streaming service, so our users can have the encrypted videos on their computers and open them only by using our streaming app.

  So what I need is to stream a freshly decrypted video file directly to a local VLC client so I don’t have to save it on disk. A minimum working example would be :

  cat my_video.mp4 | vlc -

  But this only shows the video and audio tracks, no subtitles.

  I want to know if there is a way to encode a video so that this would work with 3 audio tracks and 3 subtitle tracks.
  I would also settle for an answer explaining that it is not possible and why not.

  More details below :

  ---

  I have 3 audio tracks and 3 subtitle tracks and I am using FFMPEG.
  (The original format of the videos is mp4 with an h264 encoding)

  Currently, I am able to make streamable .mp4 files, thanks to this answer, and also to make .ts files that will show the video and the 3 audio options but not the subtitles. The command I am using is this :

  video_name=demo_0101.mp4
  
  sub_name=demo_0101.srt
  
  output=0101.mp4 # Or `.ts`
  
  
  
  ffmpeg\
  
    -i en_raw/$video_name -i pt_raw/$video_name -i es_raw/$video_name\
  
    -i en_subs/$sub_name\
  
    -i pt_subs/$sub_name\
  
    -i es_subs/$sub_name\
  
    -map 2:v\
  
    -map 0:a:0 -map 1:a:0 -map 2:a:0\
  
    -map 3:s -map 4:s -map 5:s\
  
    -c:v libx264 -crf 22\
  
    -movflags faststart\ # (This line is only necessary for .mp4)
  
    -c:a:0 aac -c:a:1 aac -c:a:2 aac\
  
    -c:s:0 mov_text -c:s:1 mov_text -c:s:2 mov_text\
  
    $output

  The problem is : The subtitles are not recognized (don’t show up at all) using the .ts format and when using .mp4 VLC reports an error :

  Unidentified codec :
  VLC could not identify the audio or video codec

  Please note when not streaming the .mp4 version works with all audios and the subtitles, i.e. :

  vlc my_video.mp4

  ---

  In case someone is wondering I plan on selecting the which subtitle and audio to play from command line with the VLC options : --audio-track 1 --sub-track 0

  I hope someone can help me. Thanks in advance.

• FFprobe command in a var in IF statement

  28 octobre 2017, par bdrilling33

  I am trying to set up a batch file (currently testing in CMD prompt) to run when there is a change in the directory. I have a command stored in a variable "test" which tells me what the first audio codec is. if it isn’t aa3 i plan to re encode the audio with ffmpeg. My first issue is that when i try to run a simple if statement with my var, i get an error.

  set test=ffprobe -v error -select_streams a:0 -show_entries stream=codec_name -of default=nokey=1:noprint_wrappers=1 "my movie (2017).mkv"

  when i run %test% it returns what is expected.

  if i run this as :

  if %test% == "ac3" echo true

  i get :

  -v was unexpected at this time.

  my end goal is to have something like this when something is added to the folder (haven’t go the when something changes part yet...probably just run this once a day idk) :

  set test=ffprobe -v error -select_streams a:0 -show_entries stream=codec_name -of default=nokey=1:noprint_wrappers=1 "%f"
  
  
  
  set outpath=S:\Blu Ray\New folder\"%f"
  
  
  
  for %f in (*.mkv) DO
  
      if %test% <> "ac3" (
  
          ffmpeg -i “%f” -vcodec copy -scodec copy -acodec ac3 -b:a 640k “%outpath%";
  
  del "%f";
  
  move "%outpath%" "s:\Blu Ray\")

  any help would be great
