  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 - Width/ Height Not Divisible by 2 (Scaling to Generate MBR Output)

  15 avril 2020, par Sanjeev Pandey

  I am trying to generate multilple variants of videos in my library (Mp4 formats) and have renditions planned ranging from 1080p to 240p and popular sizes in between. For that I am taking a video with a AxB resolution and then running through a code (on bash) which scales them to desired following sizes - 
426x240
640x360
842x480
1280x720
1920x1080, with different bitrates of course, and then saves as Mp4 again.

  



  Now, this works just fine if source video has height and width divisible by 2, but code breaks on the following line for the videos with odd width and height :
-vf scale=w=${width}:h=${height}:force_original_aspect_ratio=decrease"

  



  Where 'width' and 'height' are the desired (and hardcoded) for every iteration : E.g. "426x240", and "640x360"

  



  The Error :
[libx264 @ 00000187da2a1580] width not divisible by 2 (639x360)
Error initializing output stream 1:0 -- Error while opening encoder for output stream #1:0 - maybe incorrect parameters such as bit_rate, rate, width or height

  



  Now approaches those are explained in this one doesn't work for me since I am scaling - FFMPEG (libx264) "height not divisible by 2"

  



  And, I tried this one too but it seems all qualities are getting the same size -ffmpeg : width not divisible by 2 (when keep proportions)

  



  


  

  • This is how I tried to use this one : scale='bitand(oh*dar,65534)':'min(${height},ih)'

  


  


  



  Kindly suggest how to solve this, keeping in view that :
1. I have a very large library and I can't do manual change for every video
2. I need to scale the video and keep the aspect ratio

  



  Thanks !

  



  PS : [Edit] One way that I can see is padding all of the odd height/ weight videos using a second script in advance. This however doubles my work time and load. I would prefer to keep it in single script. This is the script I see that I can use for padding :
```ffmpeg -r 24 -i -vcodec libx264 -y -an -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2"`` (from : FFMPEG (libx264) "height not divisible by 2")
