title: Recording text/image overlay on Android
body: <p>How can I put text or transparent image into a video? I can display text overlayed camera output but how can I record it? Using opencv is an alternative but I don't really want to use opencv manager(or 25+ mb binary).</p>
  
  <p>Is there a way to record overlayed video with Android SDK or 3rd party library. What are my options?  </p>
  
  <p>Update: I'm not looking for a "record to disc then load recorded video and process every frame" solution. I'm trying to find a way to process every camera frames before recording. Something like opencv.</p>
