CameraUI auto complete?

I want to record 30s video clips using native camera and timer only with no user interaction.  A remote control will be used to start the timer on the iPad.  When the timer stops, the CameraUI will open, start the recording, and complete/close the CameraUI.

Is there an Air Native Extension or something that allow you to control the native camera?

I know there are options with using flash Camera attached to Video component and use something like FLVRecorder or Red5 embedded.  These are options.  But, I don't want the video in FLV format and I don't need the video recording done inside my app necessarily.

If I have to go with Video component approach, what is the easiest way to record the camera clips?

Thanks,

Don
