Feature description

It would be great if the camera supported Bluetooth microphones and headsets with microphones.

Why do you want this feature?

Providing support for wireless microphones makes the app much more flexible, extensible, and user friendly.

Additional information

There are currently only two apps I have found that provide the capability to use Bluetooth audio sources. I THINK they come from the same original source based on the app names and appearance of the apps themselves. Perhaps there is some source code available out there? https://play.google.com/store/apps/details?id=com.AwamiSolution.wirelessmicvideorecorder https://play.google.com/store/apps/details?id=com.sufiantech.wirelessmicvideoaudiorecorder

@summersab I know it's for helping, but it's best to avoid linking non-FOSS apps here.
