I use the following code to implement the camera part:

Intent i = new Intent("android.media.action.IMAGE_CAPTURE"); 
File photo=new File(Environment.getExternalStorageDirectory(), "123.jpg"); 
i.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photo)); 
startActivityForResult(i, 1); 

any suggestions on this???

Didn't tried it myself, but you could try to add the EXTRA_VIDEO_OUTPUT extra in the intent.

Just add:

i.putExtra(MediaStore.EXTRA_VIDEO_OUTPUT, 1);

See the reference for further information.
