title: Open Video Downloader Error: Postprocessing: ffmpeg not found
body: <p><strong>Error Thrown:</strong></p>
  <pre><code>ERROR: Postprocessing: ffmpeg not found. Please install or provide the path using --ffmpeg-location
  </code></pre>
  <p><strong>Context:</strong> macOS Big Sur M1 Chip, using the open video downloader program <a href="https://github.com/jely2002/youtube-dl-gui" rel="nofollow noreferrer">GitHub release</a> or <a href="https://formulae.brew.sh/cask/open-video-downloader#default" rel="nofollow noreferrer">Homebrew</a>. This specifically was thrown at the end of downloading the video file and the audio file from a given URL. The two files remained separate as a result of the error, the video was playable normally, but audio was in a .webm format (unusable for most people).</p>
  <p><strong>Analysis:</strong> It is clear that a dependency is missing, or its path cannot be located. For macOS users like me, the first step after checking the app's preferences for a path set or dependency download function is to check for the given dependency in the system. Once checking using Homebrew, it became clear that several dependencies were missing.</p>
