title: Where can I find the native source code of android API of camera?
body: <p>In order to make the streaming and saving data of the recording at the same time, I would like to use the output of Mediarecorder which an Api in Android to record a video.
  <br />
  However, when I save the data that produced by <code>recorder.setOutputFile</code>, It is not a legal 3gp format.
  <br />
  Therefore, I would like to study the source code of <code>camera.start()</code> and <code>camera.stop()</code> to make the output file become readable.
  <br />
  Does someone can tell me where can I find the native code of these member?</p>
