  avcodec/aom_film_grain : implement AFGS1 parsing
  Based on the AOMedia Film Grain Synthesis 1 (AFGS1) spec :
  
    https://aomediacodec.github.io/afgs1-spec/
  The parsing has been changed substantially relative to the AV1 film
  
  grain OBU. In particular :
  1. There is the possibility of maintaining multiple independent film
  
     grain parameter sets, and decoders/players are recommended to pick
  
     the one most appropriate for the intended display resolution. This
  
     could also be used to e.g. switch between different grain profiles
  
     without having to re-signal the appropriate coefficients.
  2. Supporting this, it's possible to *predict* the grain coefficients
  
     from previously signalled parameter sets, transmitting only the
  
     residual.
  3. When not predicting, the parameter sets are now stored as a series of
  
     increments, rather than being directly transmitted.
  4. There are several new AFGS1-exclusive fields.
  I placed this parser in its own file, rather than h2645_sei.c, since
  
  nothing in the generic AFGS1 film grain payload is specific to T.35, and
  
  to compartmentalize the code base.

• 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 !
