hello foss community!

Does anyone here have experience with background video recording apps? Basically an application where I could start or schedule a recording, and it would silently run in the background and collect the feed from camera, microphone, and ideally, GPS too, effectively turning the smartphone into a body camera without giving any sign on the screen that recording is going on. In order to check / finish the process, one would need to explicitly open the app.

Is there anything open-source of this kind? My primary use-case is recording my trips, but it could also be useful for security-sensitive activities. Real-time cloud synchronization would be nice too, but I guess it's not such a necessity.
