It even have a V4L2 compatiblity layer to emulate a high-level V4L2 camera device to make a smooth transition for all those V4L2 applications out there. libcamera does have a V4L2 compatability layer which is designed to allow other applications to open cameras as if they were self-contained V4L2 devices. This layer intercepts standard V4L2 system calls and translates them to libcamera API operations, enabling legacy applications to benefit from libcamera's advanced camera support. The CFE needs to be fed configuration buffers to run. I got into a situation where I have already gone through two Raspberry PI 3b+ and 3 cameras and for some particular reason I cannot make it work, because vcgencmd get_camera always outputs detected=0.
