Controlling burst mode

Hi, everybody. I recently posted a question regarding multiple shots, and I
want to elaborate on that. Here's what I have:

I have two Nikon D5300 mounted on top of a car and controlled by a
Raspberry Pi running Raspbian. The cameras are facing left and right.
Inside the vehicle I have a small embedded system that is simply a small
user interface. The cameras are in sports mode and in low-speed bursting
mode (2 to 3 shots per second), automatic focus. Each camera has a class
10, high capacity SD card and the car alternator supplies power. The
cameras are configured to take small images with basic JPEG compression,
which results in files below 1 Mbyte per picture.

I want to take pictures continuously as the vehicle travels very slowly
(about 15 miles per hour) and save them in the SD card. Using gphoto2, I
can configure burst mode, but I have to tell the camera beforehand how many
pictures to take.

The problem is that, inside the car, I have a start/stop button that I want
to use to control the cameras. I'm searching through the documentation and
the web, but I can't find a way to stop the cameras once they begin taking
pictures in burst mode. I want to be able to start and stop the burst
shooting on the Nikon D5300 using gphoto.

Any ideas? This is crucial to my project.

Thank you all.
