MediaRecorder

I use MediaRecorder class.

I set up SurfaceView.

SurfaceView mySurfaceView = (SurfaceView) findViewById(R.id.surfaceView1);
SurfaceHolder holder = mySurfaceView.getHolder();
holder.addCallback(this);
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

And set up SurfaceHolder.Callback

public void surfaceCreated(SurfaceHolder holder) {
}
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
 _holder = holder;
}
public void surfaceDestroyed(SurfaceHolder holder) {
}

Create MediaRecorder

_recorder = new MediaRecorder();

Initialize MediaRecorder and start it.

_recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
_recorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
_recorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);
_recorder.setOutputFile("/sdcard/sample.3gp");
_recorder.setPreviewDisplay(_holder.getSurface());
try {
 _recorder.prepare();
} catch (Exception e) {
 Log.e("test", "recorder error");
}
_recorder.start();

stop it.

_recorder.stop();
_recorder.reset();
