• Chrome’s New Audio Notifier

  30 janvier 2014, par Multimedia Mike — General

  Version 32 of Google’s Chrome web browser introduced this nifty feature :

  
  
  

  When a browser tab has an element that is producing audio, the browser’s tab shows the above audio notification icon to inform the user. I have seen that people have a few questions about this, specifically :

  1. How does this feature work ?
  2. Why wasn’t this done sooner ?
  3. Are other browsers going to follow suit ?

  Short answers : 1) Chrome offers a new plugin API that the Flash Player is now using, as are Chrome’s internal media playing facilities ; 2) this feature was contingent on the new plugin infrastructure mentioned in the previous answer ; 3) other browsers would require the same infrastructure support.

  Longer answers follow…

  Plugin History
  Plugins were originally based on the Netscape Plugin API. This was developed in the early 1990s in order to support embedding PDFs into the Netscape web browser. The NPAPI does things like providing graphics contexts for drawing and input processing, and mediate network requests through the browser’s network facilities.

  What NPAPI doesn’t do is handle audio. In the early-mid 1990s, audio support was not a widespread consideration in the consumer PC arena. Due to the lack of audio API support, if a plugin wanted to play audio, it had to go outside of the plugin framework.

  
  
  

  There are a few downsides to this approach :

  • If a plugin wants to play audio, it needs to access unique audio APIs on each supported platform. One of the most famous things I’ve ever written deals concerns this nightmare on Linux. (The picture worth a thousand words.)
  • Plugin necessarily needs free unrestricted access to system facilities, i.e., security measures like sandboxing become more difficult without restricting functionality.
  • Since the browser doesn’t mediate access to the audio APIs, the browser can’t reasonably be expected to know when a plugin is accessing the audio resources.

  So that last item hopefully answers the question of why it has been so difficult for NPAPI-supporting browsers to implement what seems like it would be simple functionality, like implementing a per-tab audio notifier.

  Plugin Future
  Since Google released Chrome in an effort to facilitate advancements on the client side of the internet, they have made numerous efforts to modernize various legacy aspects of web technology. These efforts include the SPDY protocol, Native Client, WebM/WebP, and something call the Pepper Plugin API (PPAPI). This is a more modern take on the classic plugin architecture to supplant the aging NPAPI :

  
  
  

  Right away, we see that the job of the plugin writer is greatly simplified. Where was this API years ago when I was writing my API jungle piece ?

  The Linux version of Chrome was apparently the first version that packaged the Pepper version of the Flash Player (doing so fixed an obnoxious bug in the Linux Flash Player interaction with GTK). Now, it looks like Windows and Mac have followed suit. Digging into the Chrome directory on a Windows 7 installation :

  AppData\Local\Google\Chrome\Application[version]\PepperFlash\pepflashplayer.dll

  This directory exists for version 31 as well, which is still hanging around my system.

  So, to re-iterate : Chrome has a new plugin API that plugins use to access the audio API. Chrome knows when the API is accessed and that allows the browser to display the audio notifier on a tab.

  Other Browsers
  What about other browsers ? “Mozilla is not interested in or working on Pepper at this time. See the Chrome Pepper pages.”

• How to track single-page websites and web applications using Piwik Analytics

  21 février 2017, par InnoCraft — Community, Development

  Single-page websites and web applications have become a standard over the last years. Getting the tracking of such websites and apps right is crucial to your success as you need to ensure the measured data is meaningful and correct. That’s why we, at InnoCraft, help our clients setting up their web tracking and measurement strategy. Some challenges our clients face are the tracking of single-page websites and web applications. We will cover this challenge in this post with a complete example at the bottom.

  Embedding the Tracking Code

  First you need to embed your JavaScript tracking code into your single-page website or web application as usual. To do this go to “Administration” in the top right in your Piwik, click on “Tracking Code” and adjust the tracking code to your needs.

  Tracking a New Page View

  The challenge begins when you need to track a new page view. A single-page app is different from a usual website as there is no regular new page load and Piwik cannot detect automatically when a new page is viewed. This means you need to let Piwik know whenever the URL and the page title changes. You can do this using the methods setCustomUrl and setDocumentTitle like this :

  window.addEventListener('hashchange', function() {
  
          _paq.push(['setCustomUrl', '/' + window.location.hash.substr(1)']);
  
          _paq.push(['setDocumentTitle', 'My New Title']);
  
          _paq.push(['trackPageView']);
  
  }

  Resetting previously set custom variables

  If you have set any Custom Variables in scope “page”, you need to make sure to delete these custom variables again as they would be attributed to the new page view as well otherwise. The following code requires Piwik 3.0.2 :

  _paq.push(['deleteCustomVariables', 'page']);      
  
  _paq.push(['trackPageView']);

  Updating the generation time

  Next you need to update the generation time before tracking a new page view. Otherwise, the initial page generation time will be attributed to all of your subsequent pageviews.

  If you don’t load new content from the server when the page changes, simply set the value to zero :

  _paq.push(['setGenerationTimeMs', 0]);
  
  _paq.push(['trackPageView']);

  In case you load new content from the server, we recommend to measure the time it took to load this content (in milliseconds) and set the needed time :

  _paq.push(['setGenerationTimeMs', timeItTookToLoadPage]);
  
  _paq.push(['trackPageView']);

  Updating the referrer

  Depending on whether you want to track the previous page as a referrer for the new page view, you should update the referrer URL by setting it to the previous page URL :

  _paq.push(['setReferrerUrl', previousPageUrl]);
  
  _paq.push(['trackPageView']);

  Making Piwik Aware of New Content

  When you show a new page, your single-page DOM might change as well. For example, you might replace parts of your page with new content that you loaded from your server via Ajax. This means you need to instruct Piwik to scan the DOM for new content. We’ll now go over various content types (Videos & Audio, Forms, Links and Downloads, Content tracking).

  Video and Audio tracking

  If you use the Media Analytics feature to track your videos and audios, whenever a new page is displayed you need to call the following method :

  _paq.push(['MediaAnalytics::scanForMedia', documentOrElement]);

  When you don’t pass any parameter, it will scan the entire DOM for new media. Alternatively, you can pass an element to scan only a certain area of your website or app for new media.

  Form tracking

  If you use the Form Analytics feature to measure the performance of your online forms, whenever a new page is displayed you need to call the following method :

  _paq.push(['FormAnalytics::scanForForms', docuemntOrElement]);

  Where documentOrElement points either to document to re-scan the entire DOM (the default when no parameter is set) or you can pass an element to restrict the re-scan to a specific area.

  Link tracking

  Supposing that you use the link tracking feature to measure outlinks and downloads, Piwik needs to re-scan the entire DOM for newly added links whenever your DOM changes. To make sure Piwik will track such links, call this method :

  _paq.push(['enableLinkTracking']);

  Content tracking

  If you use the Content Tracking feature, whenever a new page is displayed and some parts of your DOM changes, you need to call this method :

  _paq.push(['trackContentImpressionsWithinNode', documentOrElement]);

  Where documentOrElement points either to document or an element similar to the other methods. Piwik will then scan the page for newly added content blocks.

  Measuring Single-Page Apps : Complete Example

  In this example we show how everything works together assuming you want to track a new page whenever a hash changes :

  var currentUrl = location.href;
  
  window.addEventListener('hashchange', function() {
  
      _paq.push(['setReferrerUrl', currentUrl]);
  
       currentUrl = '' + window.location.hash.substr(1);
  
      _paq.push(['setCustomUrl', currentUrl]);
  
      _paq.push(['setDocumentTitle', 'My New Title']);
  
  
  
      // remove all previously assigned custom variables, requires Piwik 3.0.2
  
      _paq.push(['deleteCustomVariables', 'page']); 
  
      _paq.push(['setGenerationTimeMs', 0]);
  
      _paq.push(['trackPageView']);
  
      
  
      // make Piwik aware of newly added content
  
      var content = document.getElementById('content');
  
      _paq.push(['MediaAnalytics::scanForMedia', content]);
  
      _paq.push(['FormAnalytics::scanForForms', content]);
  
      _paq.push(['trackContentImpressionsWithinNode', content]);
  
      _paq.push(['enableLinkTracking']);
  
  });
