Is it possible to record video on a smartphone from the main and front cameras at the same time?

Question

Programming

Dear IT industry experts,
a question about the fundamental possibility: Is it possible to simultaneously record video from the main and front cameras of a smartphone. That is, when a video is being shot, it was possible to shoot both the filmed (what is being filmed) and the author of the video (the one who is currently filming). It is clear that the video is written to different files.
Maybe there are already solutions.
Thanks in advance to all who answer.
