• Premium Plugins now available on the Piwik Analytics Marketplace

  2 novembre 2016, par Piwik Core Team — Community, Press Releases

  We are super excited to announce the launch of three new premium plugins which are now available on the Piwik Marketplace : A/B Testing, Media Analytics, and Activity Log.

  All three plugins are easy to use and come with 100% data ownership, documentation, integration with Piwik, powerful data exports and no data limits.

  These first premium plugins and the new Marketplace capabilities have been designed and built with love by InnoCraft – the new company brought to you by the makers of Piwik.

  1. A/B Testing

  A/B Testing helps you grow your business by comparing different versions of your website or app to detect the most successful version that increases your sales, revenue, conversions, pageviews, and more.

  A/B tests are also known as experiments or split tests. In an A/B test you show two or more different variations to your users (visitors) and the variation that performs better wins. When a user enters the experiment, a variation will be randomly chosen and the user will see this variation for all subsequent visits. Piwik A/B testing uses advanced statistical analysis to detect which variation performs better for your conversion goals and success metrics. Even small tests can increase your sales and conversions massively !

  • A/B Testing – Experiments (website).
  • List of all features on the Marketplace : A/B Testing Plugin.

  • The A/B Testing User Guide and the A/B Testing FAQ help you getting started in running A/B tests. The A/B Testing developer guides help you embedding and implementing A/B tests into your project.

  • A/B Testing Platform for Piwik Analytics (blog post).

  

  2. Media Analytics

  Do you have videos or audio on your website, or in an app ? Media Analytics gives you powerful insights into how your audience watches your videos and listens to your audio, to ultimately maximize your success.

  Learn all about your audience. Which media your users are playing, for how long, how often, and where they dropped off ? Where are your users located around the world ? Who your audience are and what did people do before and after watching a video or listening to audio ? Many of the reports are also available in Real time, so you can gain insights and react quickly.

  3. Activity log

  Keep an eye on everything that is happening on your Piwik platform with the Activity Log plugin.

  The activity log, also known as audit log or audit trail, improves your Piwik’s security and diagnostic by showing a chronological set of entries that provides documentary evidence of activities that happened in your Piwik. It allows Piwik Super Users to quickly review the actions performed by members of your organization or clients, and also lets every user review details of their own actions.

• Change AVI creation date with ffmpeg ?

  1er novembre 2016, par brock

  As far as I can tell the following ffmpeg command should copy all existing metadata in the input file to the output file and modify the specified field in the output file :

  ffmpeg -i VID_20130502_220104.avi -metadata creation_time="2013-05-02 22:01:04" -codec copy VID_20130502_220104-2.avi

  Instead, it seems to strip all metadata from the output file. Here is the output of a few commands. I am going nuts. I think this should work, but why is it not ?

  Command to edit the creation time :

  ffmpeg -i VID_20130502_220104.avi -metadata creation_time="2013-05-02 22:01:04" -codec copy VID_20130502_220104-2.avi

• undefined reference to ffmpeg functions in native code using Android Studio 2.2

  12 octobre 2016, par Krzysztof Kansy

  I have a problem with using ffmpeg in Android Studio 2.2 using NDK 13 and new Cmake building system. FFmpeg version is 3.1.4.
  The system I’m working on is Linux Mint 18 64-bit.
  At the build time I’m getting undefined reference error each time I use ffpeg functions.

  My MainActivity.java :

  public class MainActivity extends AppCompatActivity {
  
  
  
      @Override
  
      protected void onCreate(Bundle savedInstanceState) {
  
          super.onCreate(savedInstanceState);
  
          setContentView(R.layout.activity_main);
  
  
  
      // Example of a call to a native method
  
      TextView tv = (TextView) findViewById(R.id.sample_text);
  
      tv.setText(stringFromJNI());
  
      }
  
  
  
      /**
  
       * A native method that is implemented by the 'native-lib' native library,
  
       * which is packaged with this application.
  
       */
  
      public native String stringFromJNI();
  
  
  
      // Used to load the 'native-lib' library on application startup.
  
      static {
  
          System.loadLibrary("native-lib");
  
      }
  
  }

  My native class (undefined reference is pointing to av_init_packet(&avPacket)) :

  #include 
  
  #include <string>
  
  #include <android></android>log.h>
  
  #include <libavcodec></libavcodec>avcodec.h>

      std::string hello = "Hello from C++";
  
  
  
      __android_log_print(ANDROID_LOG_INFO, "JNItest", "Hello from JNI!");
  
  
  
      AVPacket avPacket;
  
      av_init_packet(&amp;avPacket);

  Build process of ffmpeg seemed to be successful. Here’s my build script :

  #!/bin/bash
  
  NDK=/home/tito/Android/Sdk/ndk-bundle
  
  SYSROOT=$NDK/platforms/android-19/arch-arm/
  
  TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64
  
  function build_one
  
  {
  
  ./configure \
  
  --prefix=$PREFIX \
  
  --disable-static \
  
  --enable-shared \
  
  --disable-doc \

  --target-os=linux \
  
  --arch=arm \
  
  --enable-cross-compile \
  
  --sysroot=$SYSROOT \
  
  --extra-cflags="-Os -fpic -marm" \

  make clean
  
  make
  
  make install
  
  }
  
  CPU=armeabi
  
  PREFIX=$(pwd)/android/$CPU
  
  build_one

  One thing I noticed that could indicate that something is wrong with ffmpeg build is warning WARNING: /home/tito/Android/Sdk/ndk-bundle/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-pkg-config not found, library detection may fail. during building. I’m not sure if this may be cause of problems.
  

  I was trying to build for all of the ABIs, but for now I decided to focus on making just armeabi working. I’m having exact same failure after using e.g. arm64-v8a.

  Finally, here is the gradle console’s content with error :
