  avfilter/vf_tinterlace : Fix vf_tinterlace mode 6 (interlacex2)
  The purpose of this filter mode is to allow interlaced content to
  
  display properly in interlaced video modes, as described in
  
  http://forum.xbmc.org/showthread.php?tid=81834 and
  
  https://github.com/mpv-player/mpv/issues/624#issuecomment-37685195 . The
  
  filter doubles the video frame rate, but does not work properly because :
  
  (1) it does not set the properties of the output stream to indicate the
  
  doubled frame rate, and
  
  (2) it does not set an appropriate PTS on the extra frames.
  
  The attached patch fixes these problems by settling these values the
  
  same way they are set in vf_yadif mode 1 (field) which also doubles the
  
  frame rate.

• Exporting MPEG Transport Stream (.ts) keyframes to images in C/C++ ? Libavcodec / FFMPEG ?

  11 mai 2021, par CyberBully2003

  I have some buffers made up of 188 byte TS packets. When I write them to a file, I can successfully view these .ts files in a video player. MPEG-2/H.264 is the format of the Transport Streams.

  


  Now, I would like to export the keyframes from these Transport Streams buffers (or .ts files) as .jpeg or some other common image format in my C/C++ project.

  


  This is a trivial task from the command line using ffmpeg, where I just feed it the .ts file and some parameters.

  


  However, for the purpose of this project, I would like to accomplish this conversion/exporting of keyframes as images code-side in my current C/C++ directory because the raw bytes from these generated images will be put into another format.

  


  People online seem to recommend using libavcodec. There is an mpegets file in the ffmpeg source that seems like it might have some of the backend to do what I want.

  


  However, the steps needed to achieve this task using the library is not apparent.

  


  I know I could call ffmpeg from C++ and use stdin, but this isn't a preferred solution for this project.

  


  If someone could give me some guidance (and even better some example code) to accomplish this task, it would be greatly appreciated !

  


• GDPR : How to fill in the information asset register when using Matomo ?

  4 avril 2018, par InnoCraft

  Disclaimer : this blog post has been written by digital analysts, not lawyers. The purpose of this article is to explain you in details how we filled in the information asset register for Matomo. This work comes from our interpretation of the UK privacy commission resources (ICO). It cannot be considered as professional legal advice. So as GDPR, this information is subject to change.

  The information asset register is for us one of the most important parts of the GDPR implementation process. It consists of an inventory of all information systems you are using to process personal data, exactly like a ledger for an accountant. Note that small and medium-sized organizations could be exempted.

  Filling out this register can be a time-consuming activity. Therefore, we decided to show you a real case sample which we did for Matomo Analytics
