  • Keeping control of your media in your hands

    13 avril 2011, par

    The vocabulary used on this site and around MediaSPIP in general, aims to avoid reference to Web 2.0 and the companies that profit from media-sharing.
    While using MediaSPIP, you are invited to avoid using words like "Brand", "Cloud" and "Market".

  • Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur

    8 février 2011, par

    La visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
    Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

  • 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 :

    Piwik AOM Marketing Performance Report

     

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

    Piwik AOM Visitor Profile Popup

     

    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. You can find our contact details on the plugin’s website http://www.advanced-online-marketing.com.

    How to get the Piwik AOM plugin ?

    The Piwik AOM plugin is freely available through the Piwik marketplace at https://plugins.piwik.org/AOM

  • ffmpeg not converting entire video in java application

    12 décembre 2017, par Urvashi Soni

    My code converts a video into different formats (160p to 2160p). The codec of video with rotate tag 90 needs to be changed. below id the code for the same which works fine for all videos till date.

    log_wfm.debug("Changing the codec video for file [" + orgFileName + "] and name of source file ["
                       + srcFileName + "]");
               String codecFlipCommand = "ffmpeg -i " + orgFileName + " -c:v libx264 -preset ultrafast " + srcFileName;

               log_wfm.info("Executing command to change the codec of video!");
               fp = Runtime.getRuntime().exec(codecFlipCommand);

               inputStream = new BufferedReader(new InputStreamReader(fp.getInputStream()));
               outputStream = new BufferedReader(new InputStreamReader(fp.getErrorStream()));

               StringBuffer output = new StringBuffer();
               String line;
               while ((line = inputStream.readLine()) != null) {
                   output.append(line).append('\n');
               }
               log_wfm.debug("stdInputForCodecChange: " + output);

               output = new StringBuffer();
               while ((line = outputStream.readLine()) != null) {
                   output.append(line).append('\n');
               }
               log_wfm.debug("stdErrorForCodecChange: " + output);

    now have a file of size 1.5Gb. The video does not create the file with changed codec. The file till size 848.5 MB is created and then the program hangs (with no exception or error logs)
    Please suggest some way to finish this codec change process.
    The ffmpeg command converts the video, but via java application, the process hangs

  • No such filter : 'drawtext'

    29 décembre 2020, par Femzy

    My main objective is to collect user inputs and convert it to a video with black background, then the input text will be moving from left to right while the video is playing with audio in the background.

    



    Currently I was suggested to use "drawtext" but i have not find it working.
