Record video with external bluetooth mic (ie headset) Can you record a video with the built-in camera while using a bluetooth audio source? Specifically, a standard bluetooth headset.

I know that you can record audio from the bluetooth headset using an app like this. And I just want to use the built-in camera.

I tried an experiment where I started recording audio using the bluetooth recorder app, then attemped to record a video. Unfortunately, the camcorder app refused to start a video recording. And I couldn't flip the order, because once I started recording the video, opening any other app (the bluetooth recorder, for example) caused the video recording to terminate. So it looks like I can't even record the two tracks separately and simultaneously to later splice together on a computer.

Does there exist an app that records video and lets the user choose the audio input? Is this even possible for android, or does the underlying kernel have a hardcoded audio input for video mode? I am a programmer, so if no app exists, I could try my hand at writing an android app if the system is capable.
This app worked better for me:
Cinema FV-5
After installing the app, but before recording the video, do the following:

Click Settings
Click Audio Source
Select Bluetooth Mic

Then record your video.
