• Berlin website owners need consent for using Google Analytics

  Website owners in Berlin need consent for using Google Analytics

  According to the Berlin Data Protection Office, if you’re a website owner collecting and sending data to third-party services (like Google Analytics) who are also using that data “for own purpose uses” in Berlin, you are now required to ask for specific consent from visitors in order to collect that information. 

  This means you can only use Google Analytics or similar services once you’ve gotten consent from visitors. In contrast, Matomo does not use information from Cloud or On-Premise users for “own purpose uses”.

  Consent is also needed when keystrokes or mouse movements are recorded. That means you need users to consent to your usage of features like Heatmaps and Session Recordings.

  It’s advised that website owners in Berlin should check their websites for third-party content and tracking mechanisms. If you do use these third-party functions that require consent, you must either get consent or remove the functions. Consent is only effective if the visitor (whose data you’re collecting) is informed and agrees to their data being processed.

  Currently this applies to website owners in Berlin, and should likely be applied for the whole of Germany to be on the safe side.

• FFMPEG hwaccel convert WEBM to MP4 video issue

  19 avril 2020, par Yen Nguyen

  I use FFMPEG to convert webm videos into mp4 format using a Nvidia GPU GeoForce GTX 1660 card on Windows 10. It has worked perfectly since the beginning for few months but now it's stopped working with strange error as below :

  



  [h264 @ 0000013d8b5eee00] missing picture in access unit with size 431
[extract_extradata @ 0000013d8b6aef40] No start code is found.
big-buck-bunny-trailer.webm: could not find codec parameters


  



  FFMPEG version and Nvidia driver version are the same as before it just crashed overnight without a clue. I tried Googling around and did update to the latest ffmpeg version as well Nvidia driver version but it still doesn't help.
If I switch to CPU decoder (without hwaccel arg) using libx264 it just works fine.

• FFmpeg create boomerang GIF effect from video trimmed Flutter

  3 septembre 2022, par nicover

  I have a 45seconds video file which I want to create a boomerang GIF from a trimmed part of the video, let's say from 20s to 23s.

  


  I tried to run in flutter a basic GIF command :

  


  " -i $videoInput -filter_complex ${"[0]reverse[r];[0][r]concat=n=2:v=1:a=0"} $gifOutput";


  


  But it was crashing every time without a short video file (OOM) :

  


  INFO: frame=  362 fps= 15 q=-0.0 size=  162048kB time=00:00:12.06 bitrate=110074.4kbits/s speed=0.514x

Target 0: (Runner) stopped.


  


  Questions :

  


  


  • Can the video be trimmed and the boomerang GIF created in the same command ?

    


  


  • Can the GIF in the same command be scaled down (as compression for low res files) ?

    


  


  • Can preset like veryfast or medium be used for GIF creation or only for video ?

    


  


  


  Thanks in advance for any help
