Using libcamera in a C++ application
====================================

This tutorial shows how to create a C++ application that uses libcamera to
interface with a camera on a system, capture frames from it for 3 seconds, and
write metadata about the frames to standard out.

.. TODO: Check how much of the example code runs before camera start etc?

Application skeleton
--------------------

Most of the code in this tutorial runs in the ``int main()`` function
with a separate global function to handle events. The two functions need
to share data, which are stored in global variables for simplicity. A
production-ready application would organize the various objects created
in classes, and the event handler would be a class member function to
