This article is a control for recording short videos with MediaRecorder. You can set the time, space size, and whether to turn on the camera initially, etc. for video recording. This control is a combination control and inherits from LinearLayout. To prevent errors, the android.media.MediaRecorder.OnErrorListener interface needs to be implemented.
Small video recording interface
