title: Adding bitmap mask to video on Android?
body: <p>I've been looking for something about adding images to videos, but i haven't found what I wanted.</p>
  
  <p>I'd like to add a bitmap/image mask in each frame of a video (it can be recorded or from SD), keeping the original sound, and save the video to the SD with the image.</p>
  
  <p>Someone knows how it can be done in Android?</p>
  
  <p>Thnx</p>
