  The WooCommerce Analytics plugin for Matomo

  Tracking e-commerce websites is always challenging as there are so many things to be taken into consideration. However, the InnoCraft team (the professional branch of Matomo) has developed a premium feature in order to track all orders into Matomo (Piwik).

  The Matomo (Piwik) WooCommerce premium feature is straightforward and easy to install and configure. You can find the plugin settings in WooCommerce under “WooCommerce => Settings => Matomo” :

  

  Once done, you will see the data appearing in your Matomo (Piwik) when an order is completed :

  

  The InnoCraft team made sure the plugin will record all completed orders 100% correctly (eg. ignoring failed orders, not missing any completed orders). The plugin will even track orders of customers who use an ad blocker thanks to a server-side tracking technique.

  Is the WooCommerce Analytics plugin an alternative to my current Matomo tracking code ?

  No. The WooCommerce Analytics plugin only records orders and abandoned carts made through the WooCommerce plugin. It will not record any page views, events or other actions. If you are looking for a great WordPress plugin to insert the Matomo (Piwik) tracking code into your WP website, we strongly recommend WP-Piwik.

• PHP - Read and write the same file hangs

  2 février 2016, par Adracat

  I’m trying to use FFMPEG to make some works with video on the server, and something I need to do is to get the progress of the process.

  I searched a little and I found this solution which tells to write the log into a file and then reading and parsing it.

  The problem

  What is driving me crazy is that I tell FFMPEG - with exec - (process A) to write the log into a file, but when I try to read it - with file_get_contents() - (process B) it does not show the contents until process A is finished (or interrupted the PHP script).

  So, when process A finishes or it says "PHP script timeout", then I can read the file as times as I want, refreshing the page (process B) and showing the contents at the time.

  What I’ve tried

  I’ve tried to use fopen() to create the file with w, w+ and a parameters, using - and without using - fclose(). I’ve tried to use also flock() just in case it gets faster to read to process B if it knows it’s already locked and does not have to wait, but then FFMPEG is not able to write into the file.

  I’ve searched for multithreading too, but I think there must be an easier and simpler way.

  I’ve used also CURL and HTTP context, as this link suggests, but no luck.

  I’ve tried, too, to use PHP-FFMPEG but it’s not supporting the last FFMPEG version, so I cannot use it.

  When I said before "(or interrupted the PHP script)" is because I tried to wait and, when PHP got a timeout, process B worked alright and the file was still updating.

  The code

  Process A (fileA.php)

  exec('ffmpeg -y -i input_file.mp4 output_file.avi 2> C:\Full\Path\To\File\log.txt 1>&2');

  Process B (fileB.php)

  $content = file_get_contents($file);
  
  
  
  if($content){
  
      //get duration of source
  
      preg_match("/Duration: (.*?), start:/", $content, $matches);
  
  
  
      $rawDuration = $matches[1];
  
  
  
      //rawDuration is in 00:00:00.00 format. This converts it to seconds.
  
      $ar = array_reverse(explode(":", $rawDuration));
  
      $duration = floatval($ar[0]);
  
      if (!empty($ar[1])) $duration += intval($ar[1]) * 60;
  
      if (!empty($ar[2])) $duration += intval($ar[2]) * 60 * 60;
  
  
  
      //get the time in the file that is already encoded
  
      preg_match_all("/time=(.*?) bitrate/", $content, $matches);
  
  
  
      $rawTime = array_pop($matches);
  
  
  
      //this is needed if there is more than one match
  
      if (is_array($rawTime)){$rawTime = array_pop($rawTime);}
  
  
  
      //rawTime is in 00:00:00.00 format. This converts it to seconds.
  
      $ar = array_reverse(explode(":", $rawTime));
  
      $time = floatval($ar[0]);
  
      if (!empty($ar[1])) $time += intval($ar[1]) * 60;
  
      if (!empty($ar[2])) $time += intval($ar[2]) * 60 * 60;
  
  
  
      //calculate the progress
  
      $progress = round(($time/$duration) * 100);
  
  
  
      echo "Duration: " . $duration . "<br />";
  
      echo "Current Time: " . $time . "<br />";
  
      echo "Progress: " . $progress . "%";
  
  
  
  }

  The process

  I just open fileA.php on a Chrome tab and, after a few seconds, I open fileB.php on another Chrome tab (and it stays as loading).

  What I need

  I need to be able to load the file and show the information I want to show while the file is being written (by exec and FFMPEG or other PHP scripts), so I can update the progress percentage with some AJAX calls.

  Extra information

  At this point, I’m using PHP 5.4 on a IIS 7.5 with Windows 7 Professional.

  Thank you everyone for your time, help and patience !

  Best regards.

• Why my ffmpeg video encode codes does not work on other computer ?

  10 avril 2022, par Object Unknown

  I'm writing code to encode some cv::Mat images to a MP4 video. The program can run successfully in my computer which I developed it, but when I copied it (and all dlls it needs) to an other computer, it stopped work.

  Notes :

  


  


  callback is a function which prints error messsage and error code.

  
The error I recived is [uns::VideoWriter/Remux] Failed to write header to output file, error code: -22

  


  


  I want to know what is causing this and how to resolve it please.
