First, the surface type needs to be push buffers. In your Preview
constructor, add the following:
getHolder().setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
Second, you need to tell the media player where to display the video.
You have a line commented out:
//mp.setDisplay(mPreview.getHolder().getSurface());
It should look like this:
mp.setDisplay(mPreview.getHolder());
If you get stuck, take a look at the VideoView.java widget source code
on android.git.kernel.org. It's in the frameworks/base project at core/
java/widget/VideoView.java
