• Piwik 3 Development Update #2 – Git master branch will become Piwik 3

  2 septembre 2016, par Piwik Core Team — Community, Development

  As mentioned in the Piwik 3 Development Update #1 we are actively working on the new major Piwik 3 release.

  This blog post is an announcement regarding an upcoming change on our Git repository.

  On October 4th CET, we will merge the current changes done for Piwik 3 from the “3.x-dev” branch into the “master“ branch across our Piwik projects and plugin repositories. While this is not important for most of our users, it can be a problem if you have installed and deployed Piwik from git.

  • If you are currently on “master” branch and want to continue using Piwik 2, you need to checkout the newly created “2.x-dev” branch instead of “master” anytime within the next 4 weeks. Don’t forget to update your scripts and scheduled tasks (cronjobs) that may reference “master” branch.
  • If you want to receive an early version of Piwik 3 via git automatically, you won’t have to change anything.

  The final Piwik 3 release will be ready before the end of the year. If you want to give it a try, you can either use Piwik from Git and check out the “3.x-dev” branch, or download Piwik 3 from GitHub.

  Until our next Piwik 3 dev update, Happy analysis !

• How too keep highest value of ffmpeg crop detect

  15 juillet 2015, par Vincent Duprez

  Case :

  I’m converting an old archive of 18000 commercials
  I’d like to automate this reconversion from DV to some lighter and uptodate h264 mp4

  The whole process is ready but I’m stuck at the first part : cropping the black bars...

  Tools used :

  The thing is : all videos are different, I cannot use one static value, thus I use the wonderful cropdetect tool by ffmpeg which outputs me this kind of lines in the cli :

  [Parsed_cropdetect_0 @ 0xbe5e960] x1:22 x2:697 y1:93 y2:483 w:672 h:384 x:24 y:98 pts:63 t:2.520000 crop=672:384:24:98

  So the last part : crop= gives the result of the remaining frame (width, hight, starting x point starting y point. to crop the video..

  But these values are not always the same inside one video how can I extract ’the biggest values’ out of these hundreds of lines ?

  In this case, just keep crop=704:416:8:80

  Edit

  Actually, the result should take in account the lowest x1, highest x2, lowest y1 and highest y2, then create a rectangle multiple of 16 inside it...
