Answer 1

Took me two weeks to figure this out. By setting the surfaceholder to TRANSPARENT, Android will destroy the surface. Then setting it back to OPAQUE creates a new surface "clearing" the surface. Note surfacecreate and surfacedestroy events will fire, so if you have code there, beware. I put a imageview set to black to give it a black background. There maybe better ways for that.

private void playVideoA() { 
     imageViewBlack.bringToFront();
     surfaceHolder.setFormat(PixelFormat.TRANSPARENT);
     surfaceHolder.setFormat(PixelFormat.OPAQUE);
     surfaceView.bringToFront();
     mediaPlayerA.setDisplay(surfaceHolder);
     //surfaceView.setAlpha((float) 0.01);
     mediaPlayerA.start();
};
private void prepareVideoA(String url) {
     try {
        mediaPlayerA = new MediaPlayer();
        mediaPlayerA.setDataSource(url);
        mediaPlayerA.prepareAsync();
        mediaPlayerA.setOnPreparedListener(this);
        mediaPlayerA.setOnCompletionListener(this);
        mediaPlayerA.setOnBufferingUpdateListener(this);
        mediaPlayerA.setOnInfoListener(this);
    } catch (IllegalArgumentException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (SecurityException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IllegalStateException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
};
@Override
public void onPrepared(MediaPlayer mp) {
     playVideoA()
}
