Body: <p>I am trying to use ffmpeg to concatenate 2 videos (prelude and the actual content). I want the transition to start with a circle that grows from a specific location and opens the view to the second video. I tried using ffmpeg-gl-transition, which seems to have a zoomInCirlce transition, but in that case, the second video looses audio. Are there other ways to achieve this?</p>
  
  <p>Here's a link to a sample, </p>
