• New Matomo Mobile 2.4.0 released

  12 janvier 2018, par Matomo Core Team

  New Matomo Mobile 2.4.0 update is now available for Android 6+ and iOS10.3+ devices. This is the first mobile release that shows signs of the new Matomo branding instead of Piwik. Don’t be surprised if the app still shows the Piwik app icon. This is on purpose as the name of the app changed to Matomo Mobile and some users would otherwise not find the app anymore if they haven’t heard of the renaming from Piwik to Matomo before.

  What’s new in Matomo Mobile ?

  This new version brings some bug fixes and improvements to our Android and iOS apps :

  • Piwik is now Matomo which includes some name changes in the app as well as showing the new logo
  • Fixed broken “Get-involved” link
  • Links to Matomo or other websites now open in the browser app and no longer in the app itself
  • Improved visitor log to support more actions (see #12284)
  • We have updated the underlying framework bringing some performance and compatibility improvements

  Download the Apps

  Update now or install either the iOS version or the Android version. Android users can also download the latest version from our website : download Matomo Mobile 2.4.0 from our website.

  If you experience any issues with this version please let us know.

  Sponsor

  The new Matomo Mobile release has been sponsored by InnoCraft, the creators of Matomo.

• Writing only video (no audio) file using ffmpeg. av_write_header fails

  19 janvier 2018, par Kamal

  I have RTP packets with VP8 encoded data. I want to write it to a mkv file or webm file. I tried a bit, but I have not been successful yet. My code is as below

  }

  It is failing when I call avformat_write_header.

  From trace log (towards end) I see

  Please let me know why avformat_write_header is failing.
