Video recording format(.3gp or mp4) in android?

Question

I use the Intent MediaStore.ACTION_VIDEO_CAPTURE video recording method.

By default, the recorded video is stored as a .3gp file.

Answer 1

Yes

Set the MediaRecorder's OutputFormat to MPEG_4, like so:

recorder = new MediaRecorder(); 
recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);

This other SO answer describes it perfectly, as well.
