title: Recording video from camera, overlaying bitmaps, adding audio, saving to the device all in as3/AIR mobile
body: <p>I am tasked with recording a live video stream from the camera on a mobile device, then overlaying bitmaps that change over time, and adding an audio mp3 track to the video file, and then saving it to somewhere on the device like the Camera roll.</p>
  
  <p>I saw a few posts that were helpful, mostly this one: <a href="https://stackoverflow.com/questions/6407442/as3-flash-air-recording-video-with-webcam-and-save-it">AS3 Flash/AIR recording video with webcam and save it</a></p>
  
  <p>But apparently, some have experienced app freezes on desktops. I can only imagine that on a mobile device it would be worse...</p>
  
  <p>Also, how can I add the video info together with a separate audio mp3 into one file?</p>
  
  <p>Has anyone accomplished something like this?</p>
