startHighSpeedRecording abstract method
Starts a high-frame-rate (slow-mo) recording at fps (e.g. 120 / 240) to
path. Uses a dedicated high-speed capture session (Android) / high-fps
format (iOS), separate from the normal preview session. Returns 1 on
success, 0 when the device advertises no high-speed config for fps.
Photo capture and frame processing are unavailable while active.
