title: Flutter: How to use flutter_ffmpeg to add overlays like watermarks and texts to a video?
body: <p>I try to implement the <code>video_editing</code> feature to my app, and I'd tried the <a href="https://pub.dev/packages/tapioca" rel="nofollow noreferrer">Tapioca Package</a> and the <a href="https://pub.dev/packages/video_manipulation" rel="nofollow noreferrer">Video_Manipulation package</a> but found that they both do not meet my criteria, so I put my last hope on the <a href="https://pub.dev/packages/flutter_ffmpeg" rel="nofollow noreferrer">flutter_ffmpeg package</a>.</p>
  <p>But as I read through its official doc on pub.dev, not a thing on my mind but <strong>&quot;WHAT THE HECK&quot;</strong>, I can't understand what those commands are used for, and though I can't find anything related to <em>add widget overlays to a video</em>. And almost no tutorial on the web that explains how to use it.</p>
  <p>So if you successfully implemented adding <strong>watermarks/texts</strong> to a video with the ffmpeg package, please show me how. <strong>Thanks</strong>!~</p>
