  Dear Piwik community,

  We are excited today to announce our publicly available Piwik 3.0.0 beta 3 release. We have been been working hard behind the scenes on the new 3.0.0 release for almost one year now. We, the passionate team at Piwik, are dedicated to bringing you a new and improved Piwik experience and invite you to join our beta channel to switch to Piwik 3 today !

  Enable the beta release channel

  Ready to enjoy a much faster Piwik experience and the magic of a modern user interface ? Follow the instructions here and you can upgrade to Piwik 3.0.0 beta in just one click.

  Please note that beta versions have a risk of containing bugs so we don’t recommend to use on a production server. If you find and report a bug in a beta version, we will aim to fix it as quickly as possible.

  Premium plugins in Piwik 3

  In the Piwik Marketplace you can discover & download plugins to enrich the functionality of your Piwik, as well as themes to change the look and feel of your Piwik user interface. The Marketplace integration was much improved in this new release, most notably : you can now purchase and download Premium plugins within Piwik !

  Important changes

  The Piwik 3 upgrade comes with some important changes that may require your attention which we detail in this blog post and in the developer changelog.

  The full list of more than 150 changes can be found in the Piwik 3 beta changelogs : beta 1, beta 2, beta 3.

  What to do next

  When you use the Piwik beta channel and if you come across any issues in Piwik such as a bug, feature missing, regression… let us know on our tracker and create a new issue so we can get this sorted.

  As we are in the final days of Piwik 3 development, we are looking forward to your feedback and help testing !

  Welcome to the future of Piwik,

  Happy Analytics !

• how can i insert an empty subtitle

  22 avril 2020, par Ginso

  i have a bunch of mp4 files and i would like to convert them to mkv, so that the automatic selection auf audio and subtitle track of vlc works.
the thing is some of them have 4 subtitles (first german and english only for foreign languages and then german and english for all) and some of them only 2 (because in those episodes there are no foreign languages). Can i insert 2 empty subtitle tracks before them so that i can set my vlc to select the first or second subtitle when i watch them ?

  



  i convert the episodes with 4 subtitles like this :

  



  ffmpeg -i in.mp4 -map 0:0 -map 0:1 -map 0:2 -map 0:3 -map 0:4 -map 0:5 -map 0:6 out.mkv

  



  0:0 is of course the video

  



  0:1 and 0:2 are audio tracks

  



  the rest are the subtitles

  



  BTW : is there a language code for forced subtitles ? -metadata:s:s:1 language=?

  


• Code library for image processing [on hold]

  1er septembre 2014, par user3928079

  Dear Stack Overflow Users,

  I am looking to create my programming portfolio as a graduate of Kennesaw State University by July 2015, when I graduate. I want to create at least 3 cross platform programs related to video or animation. In the package there will be a program for playing video and music files, a program for converting video and music files, and either a program upscaling video and image files or a program that helps animators create animation like Flipbook Pro. Since Java is cross platform, and Java is the language I’m more comfortable with, I’ll develop the software in Java, unless of course Python is cross platform as well. May you please recommend me some image processing libraries that will help me accomplish the development of these types of software programs. For the upscaling program, an upscaling algorithm from BenVista called S-Spline Max is needed, especially since I want to preserve the detail of the image, because in upscaling, you are unable to gain new information from the original information. What are some good image processing libraries I can use. I know of OpenCV, but what do a lot of programs use, high profile or low profile, like Adobe Premiere Pro or Davinci Resolve. FFMPEG is a good video library, but can it easily accomplish what I need ? What are some others that can help me in my 11 month long quest ?

  Regards,

  Jordan White
