• flutter-ffmpeg error on mixing audio and picture - Unable to find a suitable output format for 'ffmpeg

  18 juillet 2021, par tylyo

  I'm trying to mix an audio and a picture in order to have a video with the same length of the Audio and as content an image sequence of the source picture.

  


  I tried using the flutter-ffmpeg plugin with the command :

  


  ffmpeg command: ffmpeg -loop 1 -i '/data/user/0/com.attiliopatania.apshare/cache/file_picker/20210402_112326.jpg' -i '/data/user/0/com.attiliopatania.apshare/cache/file_picker/Voice001.m4a' -c:v mpeg4 -tune stillimage -c:a copy -shortest /data/user/0/com.attiliopatania.apshare/app_flutter/out.mp4


  


  some context :

  


  I did the same test with ffmpeg on my pc and it worked as expected. I liked it.

  


  I did some test and I tried to write a file on the same path where the out file should be and It worked as expected : file created

  


  Running the same command through flutter plugin I experienced an error I'm reporting below

• put_bits : make avpriv_align_put_bits() inline

  26 octobre 2020, par Anton Khirnov

  put_bits : make avpriv_align_put_bits() inline
  This function is so extremely simple that it is preferable to make it
  
  inline rather than deal with all the complications arising from it being
  
  an exported symbol.
  Keep avpriv_align_put_bits() around until the next major bump to
  
  preserve ABI compatibility.

• Announcing Long Term Support in Piwik 2 – The analytics platform for your mission critical projects

  11 janvier 2016, par Matthieu Aubry — About, Development

  We are proud to announce our Long Term Support (LTS) for Piwik 2.X !

  Why Long Term Support (LTS) ?

  Part of our mission is to ready Piwik for the enterprise — and ready the enterprise for Piwik. Our fast release cycle and our ability to quickly innovate has served us well for the past seven years and has lead Piwik to being one of the most popular open source projects, used by over one million websites worldwide. But Piwik’s success today has also shown us that this fast release cycle is not suited for all users and customers. Like most large open source projects (such as Ubuntu, Firefox, Debian, Symfony, Node.js, etc.) at Piwik we now also offer a Long Term Support release which gives users the confidence that Piwik can be used for mission critical projects for months to come.

  What does LTS mean for Piwik ?

  For the duration of the LTS period, Piwik 2.X will continue to receive the following fixes :

  • Critical bugs causing data loss or data corruption.
  • Major and Critical security issues.

  Our goal is to offer you a Piwik LTS release that you can trust for all your mission critical projects.

  How long will Piwik 2.X be supported ?

  Piwik 2.X will be supported for at least 12 months after the initial release of Piwik 3.0.0.
  Piwik 3.0.0 is expected to be released in the second half of 2016.
  This means that Piwik 2.X will be supported at least until the second half of 2017.

  Which Piwik version is LTS ?

  The latest Piwik 2.16.X release is our Long Term Support version.

  How do I benefit from the LTS version ?

  To get the full benefits of Piwik LTS, please make sure you are using the latest LTS version. First, update to the latest Piwik 2.X version, then Configure Piwik to use the LTS release channel and then update to the latest LTS version.

  How do I configure Piwik to use the LTS version ?

  By default, Piwik will not use the LTS version. When you use the one-click update your Piwik instance will be updated to the very latest release : when Piwik 3.0.0 will be released, the one click update will update your instance to 3.0.0. It is however possible to configure your Piwik so that you will stay on Piwik 2.X and keep using the LTS Long Term Support version :

  • Login Piwik as the Super User,
  • Go to Settings > General > Update settings,
  • Under “Release channel” click “Latest stable 2.X Long Term Support version”, and click “Save”.
    

  How do I get professional Piwik Support ?

  If you need professional support for your Piwik service get in touch with the Piwik experts.
