title: Overlay image in ts file
body: <p>I'm using the FFmpeg library in Android. </p>
  
  <p>I'm able to generate a .ts file which i can play later using VLC player. But now i want my app to overlay a .png image over the whole video.</p>
  
  <p>The .ts file i want to overlay an image in is called "out.ts". The name might seem confusing, but it is called that way because it is the output of my camera.</p>
  
  <p>This is the line i'm using:</p>
  
  <pre><code>ffmpeg -i /storage/emulated/0/out.ts -i /storage/emulated/0/mustache.png -filter_complex "overlay=10:10" /storage/emulated/0/newout.ts
  </code></pre>
  
  <p>This is the output i'm receiving:</p>

  <p>Some explaination on how to tell ffmpeg where to position the .png image would be appreciated.</p>
