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

  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.

  Ideas and Support

  If you have ideas for new features or need support with your Piwik AOM installation or leveraging your marketing data’s potential in general, feel free to get in touch with the plugin’s co-author Daniel or me.

• when concatenating video segments ffmpeg shows error : "Media type mismatch between the parsed_overlay_20"

  27 janvier 2018, par user2642511

  773/5000
  I’m trying to apply a scaling and chromakey effect to different segments of a video and then combine those segments again into one.

  To improve the time and performance I have developed a program that creates all the filters in a single command.

  The plan is simple, I have a video * .mov recorded with a green screen and a background * .jpg,

  1. I first prepare a couple of backgrounds with blur effect from the JPG image
  2. I then apply chromakey to make the green part of the video transparent
  3. I trim the video to which I applied the chromakey in several time segments and to each segment I applied a scale and crop and I overlay it to one of the backgrounds prepared in step 1
  4. Concatenate all segments already processed.

  When I execute the resulting command it gives me the error

  the command is this :

  ffmpeg -i "C:\ffmpeg\pruebas\FFBlue_ProjectsFiles\chroma\green1.mov" -i C:\ffmpeg\pruebas\FFBlue_ProjectsFiles\fondos\sc.jpg -filter_complex " [1:v]scale=iw*3:-1,crop=w=iw/3:h=ih/3:y=(ih-oh)/3:x=((iw-ow)/2)+(ow/2-ow/3),boxblur=7:2[fondo_3IZQ] ; [1:v]scale=iw*4:-1,crop=w=iw/4:h=ih/4:y=(ih-oh)/3:x=(in_w-out_w)/2,boxblur=6:2[fondo_4CEN] ; [1:v]scale=iw*5:-1,crop=w=iw/5:h=ih/5:y=(ih-oh)/3:x=((iw-ow)/2)+(ow/2-ow/3),boxblur=5:2[fondo_5IZQ]  ; [0]chromakey=color=#83BD46:similarity = 0.1 : blend = 0.05,selectivecolor=reds=0 0 0 -1:yellows=0 0.1 0 -0.5:greens=0 0 -1 0:whites=0 0 0 -0.7 [vid]  ;  [vid] trim=start=0:duration=0,setpts=PTS-STARTPTS,scale=iw*4:-1,crop=w=iw/4:h=ih/4:y=(ih-oh)/3:x=((iw-ow)/2)+(ow/2-ow/3)[vid_0] ; [fondo_4CEN][vid_0]overlay[toma_0] ; [vid] trim=start=0:duration=3.41933,setpts=PTS-STARTPTS,scale=iw*3:-1,crop=w=iw/3:h=ih/3:y=(ih-oh)/3:x=(in_w-out_w)/2[vid_1] ; [fondo_3IZQ][vid_1]overlay[toma_1] ; [vid] trim=start=3.41932988166809:duration=2.85067,setpts=PTS-STARTPTS,scale=iw*5:-1,crop=w=iw/5:h=ih/5:y=(ih-oh)/3:x=(in_w-out_w)/2[vid_2] ; [fondo_5IZQ][vid_2]overlay[toma_2]  ; [toma_0] [toma_1] [toma_2] concat=n=3:v=1:a=1:unsafe=1 [v_concatenado][a_concatenado]" -map [v_concatenado]  -map [a_concatenado] "C:\ffmpeg\pruebas\FFBlue_ProjectsFiles\chroma\green1_FINAL.mov"

  when I execute it ffmpeg says :

• Convert an RTSP/RTMP-Livestream with G.711 audio into RTMP/RTSP with aac-audio

  31 août 2018, par Alex Fuhr

  im new at this forum and my english skills are not the best !

  I have a website where i publish the videostreams of the cameras to show what happens inside during the nesting-time live ! An guy with high IT-skills has build me a little Server for Restream it (Datarhei-Restreamer) But this guy has still no time and worse response-times...

  To my Problem : The Restreamer dont support the "G.711" Audio-Codec from the cameras and the Livestream are still without audio at the website. So, i need to convert the Livestreams (RTSP and RTMP- in H.264) so that the audio changes to "aac" or something other supported. But i have no plan how to do this. I tried it with FFMPEG but i dont find the correct commands to get the my result. There is something with an Streaming-server to send the new created stream to - i dont get it into my head to do this (i need just a stream that are viewable with VLC player and then as input for my restreamer-server, jsut the same like ca

  I want to change the source-stream into the correct codec (audio from G.711 to AAC, the rest like source) and then, put this "new" stream into my Restreamer-Server and it will work fine ! (Tested with XSplitbroadcaster, but dont runs on Raspberry, only 1 instance runable but 2 livestreams needs to be encoded at same time) And this programm has annoying bugs (endless and not removeable error-messages, but running stream)

  I have a new second raspberry that are planned as "live-encoder" for the restreamer-raspberry were the "new" streams are are going in (rtmp/rtsp-input on a graphical ui) I try it still with FFMPEG but still no result...

  Sorry about this long text with all the language-issues but im really frustrated with it because i have purchased 2 new cameras with total 450 euros just to get the livestream with sound now :(
