• I want to change the file name with exiftool. To “Result of adding time zone (+9) to CreateDate”

  7 décembre 2019, par user3474300

  I shot a video with a sony camera.
  A file with the extension .mp4 was created.
  I want to change the shooting date and time to a file name.
  The environment is Windows10.

  ---

  What I tried

  I first dragged and dropped the .mp4 video file to exiftool (-k) .exe.

  ExifTool Version Number         : 11.76
  
  File Name                       : C0001.MP4
  
  File Modification Date/Time     : 2019:10:23 13:10:49+09:00
  
  File Access Date/Time           : 2019:11:17 21:50:24+09:00
  
  File Creation Date/Time         : 2019:11:17 21:50:21+09:00
  
  MIME Type                       : video/mp4
  
  Major Brand                     : Sony XAVC
  
  Create Date                     : 2019:10:23 04:10:32
  
  Modify Date                     : 2019:10:23 04:10:32
  
  Track Create Date               : 2019:10:23 04:10:32
  
  Track Modify Date               : 2019:10:23 04:10:32
  
  Media Create Date               : 2019:10:23 04:10:32
  
  Media Modify Date               : 2019:10:23 04:10:32
  
  Time Zone                       : +09:00
  
  Last Update                     : 2019:10:23 13:10:32+09:00
  
  Creation Date Value             : 2019:10:23 13:10:32+09:00

  I then typed the following command at a Windows 10 command prompt :

  C:\hoge>"exiftool(-k).exe" -r "-FileNamehoge/C0001.MP4
  
  Warning: Error removing old file - C:/hoge/C0001.MP4
  
      1 directories scanned
  
      1 image files updated
  
  -- press RETURN --

  The following file was created.

  2019-10-23_04-10-32 - C0001.MP4

  ---

  How can I output the following file ?

  I don’t know how to add time zone (+9) to CreateDate.

  2019_1023_131032.MP4

• Berlin website owners need consent for using Google Analytics

  19 novembre 2019, par Joselyn Khor — Uncategorized

  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 with frei0r libraries fails on os x 10.14.6

  13 novembre 2019, par Bernhard Wagner

  I’m on Mac OS X 10.14.6 (Mojave), used homebrew to install both ffmpeg and frei0r.
  If you check the output below, the option --enable-frei0r is there.

  I verified the path to the frei0r libaries and call ffmpeg like this :

  FREI0R_PATH=/usr/local/Cellar/frei0r/1.6.1/lib/frei0r-1/ ffmpeg -v debug -i running.mkv -filter:v frei0r=pixeliz0r=0.02:0.02 pixel.mkv

  however it fails the exact same way as if I hadn’t passed the env var FREI0R_PATH :

  FREI0R_PATH=/usr/local/Cellar/frei0r/1.6.1/lib/frei0r-1/ ffmpeg -y -v debug -i running.mkv -filter:v frei0r=pixeliz0r=0.02:0.02 pixel.mkv
