• No sounds on Apple devices after encoding videos [migrated]

  15 décembre 2013, par Ricardo

  I'm having a problem setting up a media server.
  Everything works just great except the sound of Apple devices, I'm not sure if that's something with "mute" on iOS or our codecs are just not compatible with iOS.

  By default I use 'libmp3lame' now because 'libfaac' is not supported by ffmpeg
  and when Im trying to encode sound by libfaac I'm getting that codec not found

  Thanks in advance !

• Creating a thumbnail from MP4 video crashes on shared hosting but working fine locally

  15 juillet 2019, par Mariam Nagy

  i am working on a web page to upload MP4 video and getting a thumbnail from the video

  i am using NReco FFMpeg Converter to achieve this . it is working fine locally but upload it on a shared hosting it crashes at ffMpeg.GetVideoThumbnail

          string VideoUrl = dataMediaUrl.ImageUrl;
  
          string extension = VideoUrl.Split('.')[VideoUrl.Split('.').Length - 1];
  
          var ffMpeg = new NReco.VideoConverter.FFMpegConverter();
  
          string thumbnailJPEGpath = Server.MapPath(VideoUrl.Replace("~/upload/MediaGallery/", "~/upload/MediaGallery/Thumb_").Replace("." + extension, ".jpg"));
  
          ffMpeg.GetVideoThumbnail(Server.MapPath(VideoUrl), thumbnailJPEGpath);
  
          dataThumbUrl.ImageUrl = VideoUrl.Replace("~/upload/MediaGallery/", "~/upload/MediaGallery/Thumb_").Replace("." + extension, ".jpg");

• 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.
