• It’s January 28th : Let’s celebrate Data Privacy !

  29 janvier 2018, par Matomo Core Team

  It is a special Sunday here for us at Matomo, as today is international Data Privacy Day. The day was created in 2007 to raise awareness of the importance of data privacy for people and businesses worldwide.

  

  What is data privacy about ?

  Personal data refers to any data which is collected and can be linked to an individual human being such as phone records, credit card transactions, GPS position, IP addresses, browsing history… So basically, personal data refers to your identity online. That is why you should be highly concerned about sending your personal data (or your customers’ personal data) away. It is important to be aware of who is collecting the information and how it is being used.

  What big changes are happening in 2018 ?

  New privacy regulations GDPR comes into play next May 2018 : GDPR will bring about some changes (in the right direction) by making people and businesses aware of what data privacy means, and what they should be doing to protect their customers’ privacy. With these new regulations, data privacy awareness is reaching a critical milestone this year.

  How can I protect my privacy ?

  Here are a few tips to protect your privacy :

  • Educate yourself on the importance of privacy : the more informed you are the better.
  • Use open source solutions where you can keep full control of your own data (such as NextCloud instead of Dropbox and of course Matomo instead of Google Analytics),
  • Experiment with different online services to protect your data privacy, for example using an alternative search engine (such as DuckDuckGo instead of Google) or an alternative email provider (such as ProtonMail).

• Python Youtube-dl convert to mp4

  27 mars 2021, par Church.exe

  (if it matters, I'm on windows)

  


  So I am trying to download a Youtube video in an Mp4 format (the program I am putting it into has limited compatibility) with audio but whatever I find online either doesn't work how people are saying it does (leading me to believe it is either outdated, missing context, or for a different OS) or is formatted in a way that doesn't make sense.

  


  My current code is :

  


  if PreferredOutput == 1:
    with youtube_dl.YoutubeDL({'format' : 'bestvideo+bestaudio[ext=m4a]/bestvideo+bestaudio/best', 'merge-output-format' : 'mp4'}) as ydl:
        ydl.download([url])


  


  but when I test it, it just seems to output the file as normal.(which I am guessing is the format the video file was uploaded to youtube as though I could be mistaken) What should I do/am I missing to make this only output (final) Mp4s ? (after the fact ffmpeg conversion or something similar is fine for my purposes)

  


• ffmpeg decode one video frame at a time

  28 juillet 2014, par Krishna

  Most ffmpeg examples online show video decoding using a while () and the entire sequence is decoded in one attempt. For example,

  while(av_read_frame(pFormatCtx, &packet)>=0) {
  
      if(packet.stream_index==videoStream) {
  
  
  
          // Decode video frame
  
          avcodec_decode_video(pCodecCtx, pFrame, &frameFinished,
  
                       packet.data, packet.size);
  
  
  
          // Did we get a video frame?
  
          if(frameFinished) {
  
               ... do something   
  
          }
  
       } 
  
  
  
    // Free the packet that was allocated by av_read_frame
  
    av_free_packet(&packet);
  
  }

  Is there a technique to (1) create a function that will decode only one frame and (2) then call that function repeatedly (how many ever times needed).

  I wrote such a function and tried to decode an HEVC stream and I always get this error "Could not find ref with POC xx", where xx stands for some integer. Looks like it can’t find references — how do I get around this ?

  Thanks !
