  The WooCommerce Analytics plugin for Piwik

  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 Piwik) has developed a premium feature in order to track all orders into Piwik.

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

  

  Once done, you will see the data appearing in your 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 Piwik 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 Piwik tracking code into your WP website, we strongly recommend WP-Piwik.

• libffmpeg writes bad mp4 file if the RTSP stream loses packets

  5 avril 2017, par user92238

  I’m working with libffmpeg in iOS, using it to open an RTSP stream and save the data to a file.

  I’ve been able to successfully save video files in both .mp4 and .mov formats, but there is a problem.

  If the RTSP stream is perfect — that is, if there are no dropped packets — then the resulting file is fine. I can play it in a player, and I can even transcode it using an AVAssetExportSession.

  The problem is, I’m dealing with a wireless camera that sends data over UDP only, so there are often dropped packets. When a dropped packet occurs, the resulting file has a big glitch in it : even if it’s just one or two packets, the playback freezes for about 12 seconds. Also, I cannot use AVAssetExportSession with these files. It fails, reporting a decoding problem.

  I feel like there must be some way I can cause ffmpeg to write a valid mp4 file when packets are missing. I don’t care what happens, whether the missing packets are simply deleted from the file or if they are replaced with something, I just don’t want a 12 second freeze.

  For what it’s worth, if I take the file off of my iOS device and play it on my computer, it plays fine. There’s a small glitch where the frame was dropped, but it doesn’t freeze for 12 seconds or anything.

  Thanks.

• Change Encoding of StandardInput.WriteLine

  25 avril 2018, par abdullah cinar

  I am trying to run ffmpeg executable using the Process to convert an input audio file to mp3 format. Below is the example call that works very well when I do it from the cmd.exe in Windows :

  "ffmpeg.dll -i "inputPath\input.wav" -vn -ar 44100 -ac 2 -ab 320k -f mp3 -y "outputPath\output.mp3"

  The input or output file paths can contain Turkish characters like ş ö ç ğ. So I have to take care of the encodings of StreamWriter.

  My snippet for the StreamWriter is :

  Process cmd = new Process();
  
  cmd.StartInfo.FileName = "cmd.exe";
  
  cmd.StartInfo.RedirectStandardInput = true;
  
  cmd.StartInfo.CreateNoWindow = false;
  
  cmd.StartInfo.UseShellExecute = false;
  
  cmd.Start();
  
  
  
  Encoding tr_encoding = Encoding.GetEncoding("iso-8859-9");
  
  
  
  using (StreamWriter sw = new StreamWriter(cmd.StandardInput.BaseStream, tr_encoding))
  
  {
  
      sw.WriteLine(ffmpeg_cmd + " & exit");
  
  }
  
  
  
  cmd.WaitForExit(); 

  But I always get No such file or directory error from the ffmpeg because the filepath contains a folder named as şşşş but my StreamWriter sends that folder name as ■■■.
