• How to draw - dynamic - "safe areas" in ffplay

  16 juin 2023, par F.O.R.A.R.T.

  we need to preview videos with overlayed so-called "safe areas" according to this EBU document : SAFE AREAS FOR 16:9 TELEVISION PRODUCTION.

  


  Here's the scheme for 1080p resolution :
1080p Safe Areas

  


  Those consist of three different "zones", each with the same percentage size-to-the-edge of the video frame for any resolution :

  


  

  • Action Safe Area (GREEN box) : 3.5%

  


  • Graphics Safe Area (RED box) : 5%

  


  • 4:3 Safe Area (GREY box) : 16.25%

  


  


  It should be easily achieveable using the drawbox command, but how can be dynamically adapted to any video resolution ?

  


• vaapi_encode_h265 : Ensure that ref pics are always in the RPS

  vaapi_encode_h265 : Ensure that ref pics are always in the RPS
  When making a new P-frame when B-frames are present the previous P-frame
  
  is normally in the DPB because it will be referred to by subsequent
  
  B-frames.  However, this is not true if there are no B-frames, or in edge
  
  cases where a GOP ends with two P-frames.  Fix this by adding the direct
  
  ref pics to the RPS explicitly.
  Fixes #7699.

• Announcement : Piwik to focus on Reliability, Performance and Security

  7 octobre 2014, par Matthieu Aubry — About, Community

  To our valued team and community,

  Well, we have moved fast and achieved so much during the past few months. Relentlessly releasing major version after major version… We got a lot done including several major new features !

  The speed of adding new features was a great showcase of how agile our small teams and the larger community are. And I’m so proud to see automated testing becoming common practice among everyone hacking on Piwik !

  For the next few months until the new year we will focus on making what we have better. We will fix those rare but longstanding critical bugs, and aim to solve all Major issues and other must-have performance and general improvements. The core team and Piwik PRO will have the vision of making the existing Piwik and all plugins very stable and risk free. This includes edge cases, general bugs but also specific performance issues for high traffic or issues with edge case data payloads.

  We’ll be more pro-active and take Piwik platform to the next level of Performance, Security, Privacy & Reliability ! We will prove to the world that Free/Libre Web software can be of the highest standard of quality. By focusing on quality we will make Piwik even easier to maintain and improve in the future. We are building the best open platform that will let every user liberate their data and keep full control of it.

  If you have any feedback or questions get in touch or let’s continue the discussion in the forum.

  Thank you for your trust and for liberating your data with Piwik,

  Matthieu Aubry
  Piwik founder
