Wouldn't you use the DVR from the FPV connect on your mobile or general DVR on the goggles? It might be dangerous to have a single button on the goggles that cuts the feed. If that button gets pressed during a flight it could be what causes the crash.
Watching the video on your phone would only take a few extra seconds.
the desired button could be that battery-check button, just hold it a couple of seconds and it could stop recording and starts playing the last video reversed!?
