  30 octobre 2013, par Piwik team

  Mattias Levin, a Mobile developer enthusiast from Sweden, has released the first public beta version of the official Piwik SDK for iOS !

  If you are building apps for iOS or OSX, you will be able to track your App usage with Piwik. Learn more in this blog post.

  Apps & Mobile apps Analytics

  Using Piwik to track your app usage would give interesting statistics usage such as :

  • number of active users (per day, week, month, …) of my mobile or desktop app,
  • how long users spend in the app,
  • track which icons, buttons are clicked (or any other custom event),
  • record device info, operating system,
  • reports on any Custom Variables you that are relevant to your app (see examples below),
  • how often is the app opened ? When and how long is the app opened ?
  • number of new users, active users, total users,
  • record errors or exception thrown

  Piwik SDK for iOS
  

  The PiwikTracker is an Objective-C framework (for iOS and OSX) designed to send app usage data to a Piwik analytics server. It is realeased under MIT license. Piwik server is a downloadable, Free/Libre (GPLv3 licensed) real time analytics platform.

  2. Download the PiwikTracker SDK.
  3. Add the PiwikTracker files to your project.
  4. Create and configure the PiwikTracker.
  5. Add code in your app to track screen views, events, exceptions, goals and more
  6. Let the dispatch timer dispatch pending events to the Piwik server, or dispatch events manually.

  For more info, check out the Readme.

• ffmpeg iOS and SDL2

  24 décembre 2015, par user3487978

  I created a app for iPhone, the core source is based on the latest ffplay.c, I just changed the rendering part to support iOS, general it can play video, but I found the quality is not as good as enough, see screenshot below, the first image is the what expected, the second is image that my app on iPhone produced, and the last the produced by my app on iPad.
  on the iPhone’s image, you can found there is a dash line, and the colour is not correct, it seems that there is a shadow of the image.
  I am new to ffmpeg, can anyone help me what is the problem

• AudioQueue bytes to ffmpeg understandable WAV format

  24 décembre 2015, par moeseth

  I got the recorded AudioQueueBufferRef buffer using the following code.

  NSData *data = [NSData dataWithBytes:inBuffer->mAudioData length:inBuffer->mAudioDataByteSize];

  And then, I send the data to my server. However, FFMPEG isn’t able to read that because the data is not in any audio standard format.

  It’s just plain data.

  So, how do I do either on iPhone or backend ffmpeg to convert that raw buffer to WAV ?

  Thank so much.
